HANDICAP CONDITIONS AND THEIR MANAGEMENT Developmental disability is not a term denoting clinical diagnosis but a grouping, established for the purpose of planning programme. Terms like mental retardation and epilepsy, on the other hand imply specific clinical diagnosis that fall into broad grouping know as developmental disabilities. The term handicapped in somewhat more inclusive than developmental disabilities but it is not the most acceptable term. Disabled is preferred and includes all forms of so called handicapping conditions. The dental condition of handicapped children may be directly or indirectly related to their physical or mental disabilities. The child born with cleft lip and palate or both may suffer from dental problems of great complexity and severity. MR children and those with cerebral palsy heart disease and bleeding disorders may not have specific dental problems but their physical or mental handicappers often hinder good oral hygiene and dietary habits, thereby creating a serious threat to their oral health. Defination A disabled child is one who has mental, physical, medical, or social conditions that prevents the child from achieving full potential when compared to other children of the same age. WHO – defines handicapped individual as one who over an appreciable time is prevented by physical or mental condition from full participation in normal activities of his age group, including those of a social, recreational, educational, and vocational nature. 1


American Public Health Association (APHA) “A child who cannot within limits play, learn, work, or do things other children of his age can do, he is hindered in achieving his full physical, mental and social potentialities”. Harris defined 3 terms: 1) Impairment – lacking part of body or all limbs or having defective limbs, organ or mechanism of body. 2) Disablement- in loss or reduction in functional ability. 3) Handicap – is the disadvantage or restriction caused by disability. Mental Handicap Mental handicap is states of arrested or incomplete development of mind. Physical Handicap WHO (1952) states that child one who over an appreciable period of time is prevented by physical or mental conditions from full participation compared to children of same age group including social, recreational, vocational nature. Classification I)

e) Epileptic. f) Physically handicapped. g) Defect of speech. h) Senile. II)

Holloway and Swallow (1982) Divided into 3 categories: a) Mental handicap. b) Physical handicap. c) Medical disability or disabilities.

III)

Nowak (1964)

Classified into a) Physically handicapped. b) Mental retardation. c) Congenital defect (SABE, Fallots tetralogy). d) Metabolic and systemic disorders e.g., DM. e) Convulsive disorders. f) Childhood autism. g) Blind and deaf. h) Hemophilia. Management of a handicapped child during dental treatment Since hospital visits or previous appointments with physician frequently result in the development of apprehension in the patient,

3


additional time with the parent and child is needed to establish rapport and dispel anxiety. If patient cooperation can’t be obtained, the dentist must consider alternatives such as physical restraints to perform dental procedures. Physical restraints Physical restraint is only one means of behaviour control to achieve an adequate level of dental treatment. Parents must be uniformed and given consent before use of physical restraints. Physical restraints is useful for managing extremely resistant patients who need dental care. Common mechanical aids for maintaining the mouth open are: -

Padded and wrapped tongue blades.

-

Molt mouth prop – allows accessability to opposite side of the mouth and operates on reverse scissor action.

Disadvantages – Lip and palatal laceration and luxation of teeth. Finger guard – It fits on the dentists finger. Disadvantage – Limited mobility of dentists hand. Rubber bite block (Mckesson bite blocks) These fit on occlusal surfaces of the teeth and stabilize the mouth in open position. Body control is gained through variety of methods and techniques like: Body -

Papoose board.

-

Triangular sheet.

-

Pedi wrap.

-

Bean bag dental chair.

-

Extra assistant.

Extremities -

Posey straps.

-

Velcro straps.

-

Towel and tape.

-

Extra assistant.

Head -

Forearm body support.

-

Head positioner.

-

Plastic bowl. Physical restraints should never be used as punishment. An

explanation of their benefits should be presented by the dentist before their use. The mouth prop can be identified as “tooth chair”, pediwrap as “safety robe” and restraining strap as safety but careful explanation should be given to patients, that physical restraints minimizes accidental injury and allow the needed dental work to be done. Prevention of handicapped child Prevention is the most important consideration in ensuring good dental health for any dental patient. 1) Home care – control of plaque, tooth brushing and flossing. 2) Diet and nutritional counseling. Home care The parents have a initial responsibility for establishing good oral hygienic in home.

5


-

Reinforcement of good home dental

care and follow up

observations can be provided through news papers, radio, TV. -

If child is institutionalized, the staff should be instructed in the proper dental care programme.

-

Although independent brushing is not contraindicated, parents and staff should known that unsurprised oral hygiene procedures in disabled children can have serious dental consequences.

-

Since disabled patients have gross motor deficiencies, thus ability to brush is hampered. One technique often recommended is the horizontal scrub method because it is easy and yielded good result.

Diet and nutrition: Diet and nutrition influence dental caries by affecting the types and virulence of the microorganism in dental plaque, the resistance of teeth and supporting structures and properties of saliva in oral cavity e.g. conditions associated with difficulty in swallowing, such as severe cerebral palsy, may require patient on liquid diet. Particular emphasis should be placed on discontinuation of bottle by 12 months of age after teeth begin to erupt, to decrease the likelihood of nursing caries. TYPES OF TRANSFER 1) Slide board transfer. 2) One person transfer 3) Two person transfer. 1) Slide border transfer – covered for patients who have good upper body strength and control but little or low lower body strength: 6


a) Remove footrests and side arm nail. b) Raise dental chair arm. c) Place the wheel chain with brakes as close as to the dental chair, is the patient is hemiplegic position dental chair to his strong side. d) Adjust height of the dental chair corresponding to the height of the wheel chair. e) Patients and eat but and place slide board under the patient. f) Keep wheel chair from tipping while patient transfers. g) Place patients legs into position in the dental chair once he has transfer. 2) One person transfer – for patients who have moderate strength or body control, but may fluid slide board to tracing – paraplegic, patients with cerebral palsy, muscular dystrophy. a) Remove footrests on wheel chair and side arm. b) Raise the arm of dental chair. c) Place the wheel chair at approximately 30° angle to the dental chair to facilitate kivotar type motion during transfer. d) Sit the brakes and adjust the height of dental corresponding to the wheel chair. e) Infaster, patients seat belts and block the patients knee and foot closest to the dental chair with your knee and foot closes to dental chair.

7


f) Have the patients place his hands around your neck while you hold patients waste or belt. g) On the predetermined signal help the patient stand, using his blocked knee and food as a pivot. h) Slowly pivot the direction of the dental chair and let the patient down into the chair. i) Place patients legs and body in proper position in the chair. 3) Two person transfer – used for patients with severely limited motor function in all extremities when using this teeth remember to keep the back and left with the legs. a. Follow ‘1’ through ‘7’ for the slide board transfer. b. Remove the head rest on the dental chair. c. One person approaches the patient from behind and has the patients cross his arms by possible, place your arm under the patients arm fits and grab the opposite wrist with each hand. a) The second person is responsible for lifting and guiding the lower limbs and should bend at the legs so as to lift with the legs, not the back. b) On a predetermined signal ask the patient to pur his elbows into his body and both persons doing the transfer lift the patient straight up stop for a second before you move laterally to the dental chair. c) Move laterally to dental chair, making so to clear any obstacles and lower the patient.

8


Maintain support of the patients head until the dental chair headrest is replaced. MENTAL RETARDATION (MR) Definations Mentally challenged child-American Association of Mental Deficiency (AAMD) and reported by Holmes et al  “subaverage general intellectual functioning which originates during the developmental period and is associated with impairment in adaptive behaviour. MR is general term applied to persons whose intellectual development is significantly lower than that of normal persons and whose ability to adapt to their environment is consequently limited. Capute – defined subaverage general intellectual functioning “as developmental or intelligence quotient (IQ) that is below 70 and represents 2 or more standard deviation (ISD=15 or 16 patients) from a mean of 100. When this level of intellectual functioning exists concurrently with “impairment in adaptive behaviour” the inference is that the MR person does not possess the independence and social responsibility excepted within age and cultural group with the limit of 18 years of age. Thus, to diagnose MR – he should possess: 1) An IQ score of more than 2 SD below the mean (IQ below 70). 2) An accompanying impairment in adaptive behaviour. 3) Manifestations of both before 18 years of age.

Classification 1) Mildly retarded – is one, who because of low intelligence, cannot derive full benefit from regular education. In academic environment these children are classified as educable mentally retarded (EMR). Educational programs for such children are generally simplified versions of regular school program and usually lead to literacy and attainment of necessary skill for employment. Most children (80%) of them in this group will function acceptably as adults. 2) Moderately retarded – children who are capable of some education and partial independence but who are not accepted to experience full independence as adults. Educational programs for such children, who are known as Trainable mentally retarded (TMR). Focus on basic skills, classification are often designed, furnished like home and the curriculum includes, dressing, grooming, cooking, table setting, feeding and cleaning. These children leave in a sheltered home with trained personnel. Classification of MR Degree of MR

These are confined to institutions. They

11


communicate with grunts, they lack communicable skills or they are mute. Etiology The etiologic classifications: 1) Prenatal Genetic diseases. Maternal and fetal infections. Kernicterus Fetal alcohol syndrome.

12


2) Natal Birth injuries Infection Cerebral trauma Hemorrhage Anoxia Hypoglycemia 3) Postnatal Cerebral infections. Cerebral trauma Poisoning Cerebral vascular accidents. Post immunization encephalopathy Malnutrition Dental treatment for MR Providing dental treatment for MR person requires adjusting to social, intellectual and emotional immaturity. The dentist should assess the degree of MR by consulting the patients physician. The following procedure have proved beneficial in establishing dentist-patient rapport. 1) Give a brief tour of the office before attempting treatment. Introduce the patient to the staff. This will reduce the fear of unknow. 13


2) Speak slowly and in simple terms. Make sure the patient has understood the explanations. 3) Give one instruction at a time. Reward the patient after successful completion of procedure. 4) Listen carefully to the patient, as the MR persons have less communicative skill and hence the dentist must be sensitive to the gestures. 5) Keep appointment short. Gradually progress to the different procedures. 6) Schedule the patient early in the day. 7) The medical history provides information regarding the cause and extent of the patients retardation. 8) Premedications can be helpful in allowing the anxieties of the retarded patient decrease. EPILEPSY The term epilepsy, which refers to a symptom, not a disease, is of Greek origin and means “to Seize�. Various disorders may cause abnormal neuronal discharge in the brain that may induce a seizure. Etiology Nelson et al described seizures disorders in children, divided into 2 groups idiopathic and symptomatic. In idiopathic- the epilepsies cannot be attributed to demonstrable structural lesion of the brain and are frequently a genetic origin. In symptomatic – group associated with pathology of the brain due to developmental anamolies, injury or disease of the brain. 14


Seizures can be classified: 1)

Grand mal seizures They are generalized, usually occurring with tonic and clonic phases

of muscular spasm. -

Their onset is rapid.

-

The patient loses consciousness and becomes pale.

-

Pupils dilate, eyeballs roll upwards or to one side.

-

There is rapid contraction of jaw muscles.

-

micturation and defecation may occur.

-

Patients experiences cyanosis during tonic phase (contraction of muscles lasts for 20-40 seconds).

-

The clonic phase (alternating contractions and relaxation) lasts for variable periods.

-

Patient awaken from the seizure with severe headache and in general state of confusion.

2)

Petit mal These appear between 3 years of age and puberty, more in girls -

There is transient loss of consciousness.

-

Occurs once or twice a month or several hundred times a day.

-

They last for 30 seconds.

-

Upward rolling of eyes.

-

Drooping or rhythmic nodding of head, quivering of trunk of thumbs.

15


Psychomotor seizures They are difficult to recognize and control. -

There is loss of postural tone.

-

There are no clonic and tonic movements.

-

The dentist should prevent the patients from injuring himself.

Focal Seizures These seizures are produced by injury to the brain (trauma, toxic agents) -

They are referred to as Jacksonian seizures.

-

They are sensory or motor and are clonic in nature.

-

The muscles most frequently involved are the most specialized for voluntary movements in the hand, face, tongue.

Dental Management Most convulsive disorders are controlled through medication and pose few problems in dental treatment. The dentists should ask the following questions during history taking of all seizures patients. 1) What was the age of the patient at the time of onset of the seizure. 2) How many types does the patient have. 3) What is the frequency of seizures. 4) Does the patient tend to injure himself during the attack. 5) Do the seizures occur at any particular time of the day.

16


6) How does the patient act immediately preceeding the seizure and after the seizure is over. 7) What type of medications is the patients taking and when is it taken. During the treatment -

Since anxiety is frequently precipitating factor, premedication with minor tranquilizers can be considered.

-

The drug regime of the patient should be evaluated.

-

The use of mouth prop is mandatory during treatment.

-

The dental units must be pushed away from the working field. In case the patient during tonic phase of seizure to avoid injury.

-

They major concern of the dentist during seizure is to ensure that patients does not suffer physical harm.

-

Loosen the patients clothing.

-

Turn the patients head to the side, pull the rubber dam material on youngs frame to evacuate the oral secretions.

-

Always talk to the patients, where he is, who are you, every thing is fine. If his restorative procedure have already stated, either temporize or

complete the procedure, unless some injury has occurred or systemic parameters are not within normal range. -

If appliance are indicated for tooth movements or tooth replacement purpose – fixed type is preferred.

-

Appoints should be given just after the patient has taken daily medications.

CEREBRAL PALSY Nelson et al used the term cerebral palsy to describe a group of nonprogressive disorders resulting from malfunction of motor centers and pathways of the brain. These are characterized by paralysis, weakness, incoordination, or other aberrations of motor function that have their origin prenatally, during birth, or before the CNS has reached relative maturity (before age 5). A person with cerebral palsy characteristically has a motor disability that is manifested as a loss or impairment of voluntary muscle, weakness, stiffness or paralysis, poor balance or irregular gait and uncoordinated or involuntary movements.

Dental management 1) Consider treating patient confined to a wheel chair. Many express such preference for young patients, the wheel chair may be tipped back into dentists lap. 2) If a patient is to be transferred to the dental chair, ask about a preference for the mode of transfer. 3) Make an effort to stabilize the patients head throughout all phases of dental treatment. 4) Try to place and maintain the patient in the midline of dental chair with arms and legs as close to body.

22


5) Keep patients back slightly elevated to minimize difficulties in swallowing (not in supine position). 6) On placing the patient on dental chair determine patients degree of comfort and assess the position of extremities do not force the limbs to unnatural position, consider pillows and towels for support. 7) Use

physical

restraints

judiciously

for

controlling

failing

movements. 8) For control of involuntary jaw movements choose from variety of mouth props and finger splints. 9) To avoid startle reflex reaction, avoid such stimuli as abrupt movements, noises and lights without forewarning the patients. 10)Introduce intraoral stimuli slowly to avoid eliciting a gag reflex. 11)Use rubber dam for restorative procedures. 12)Work efficiently, and minimize patient time in chair to decrease fatigue of involved muscles. 13)Pre medication is a useful modality in management in case of fear and apprehension. 14)If the patient is difficult to manage, GA is considered. DEAFNESS Deafness is a handicap that is often overlooked. Almost inevitably, speech in affected. If the impairment is severe enough that dentists and child cannot communicate verbally, the dentist must use sight, taste and touch to communicate and allow the child to learn about dental experiences.

23


The causes for hearing loss 1) Prenatal factors -

Various infections – rubella, influenza.

-

Ototoxic drugs.

-

Congenital syphyllis.

-

Heredity (waardenbarg syndrome).

2) Perinatal factors -

Prematurity.

-

Birth injury.

-

Anoxia.

3) Post natal factors -

Various infections – mumps, measles influenza, poliomyletis, meningitis.

-

Injuries.

-

Ototoxic drugs – aspirin, streptomycin, neomycin, kanamycin.

Dental Management 1) Prepare the patient and parent before the first visit. 2) Through the parent, determine during the initial appointment how the patient desires to communicate, thus decreasing the child fears. 3) Assess speech and language ability and degree of impairment by taking a complete history. 4) Face the patient and speak at natural pace and directly to the patient, so that the patient can lip read.

24


5) Watch the patients expression make sure the patient understands what dental equipments is, what is going to happen and how it will feel. 6) Reassure the patient with physical contact, hold the patients hand initially. 7) Employ tell-show-do approach, allow the patient to see the instruments and demonstrate how they work: E.g. vibrations of handpiece, scratching of explorer, scooping of excavator, texture of rubber dam. 8) Use smiles and reassuring gestures to build up confidence and reduce anxiety. 9) Avoid blocking the patients visual field. 10)Adjust the hearing aid (E.g., the patient has one) while the handpiece is the operation since hearing aids amplify the sounds. BLINDNESS A person is considered to be affected by blindness if the visual acuity does not exceed 20/200 in better eye, with correcting lens or if the acuity is greater than 20/200 but accompanied by visual field of no greater than 20 degrees. Etiology of Blindness Prenatal causes -

Optic atrophy.

-

Micropthalmus.

-

Cataracts.

25


-

Colobomas – defective growth.

-

Dermoid and other tumors.

-

Toxoplasmosis.

-

Cytinegalic inclusion disease.

-

Syphilis.

-

Rubella.

-

TB meningitis.

-

-

Hypertension.

-

Premature birth.

-

Polycythemia vera.

-

Hemorrhage disorders.

-

Leukemia.

-

Diabetes mellitus.

-

Glaucoma. Blindness is one disorder

that may result in frequent

hospitalization, separation from family and slow social development. Dentist should relize that congenitally blind children need greater display of affection and love early in life. Explanation is accomplished through touching and hearing, reinforcement takes place through smelling 26


and tasting. The modalities of listening touching, tasting and smelling are important for blind children. Reports reveal that motor activity affects the development of language and perception. Blind children tend to have more accidents than other children while acquiring motor skills. Trauma to anterior teeth, gingival inflammation because of inability to see and remove plaque. Before initiating treatment for blind dentist should keep following points in mind. 1) Determine the degree of perception of the light (visual impairment) e.g., can the patient tell light from dark. 2) Avoid expressions of pity or references to blindness as an affliction. 3) In maneuvering the patient to the operatory ask the patient for assistance. Do not grab, move, stop without verbal warning. 4) Describe the office setting. Always give the patient adequate descriptions before performing treatment procedures. 5) When making physical contact, do so reassuringly. 6) Introduce other office personnel very informally. 7) Allow the patient to ask questions about the course of treatment and answer them. 8) Allow the patient who wears eyeglasses to keep them on for protection. 9) Avoid sight references.

27


10)Rather than tell-show-do approach, invite the patient to touch, taste, or smell. 11)Describe in detail instruments and objects to be placed in patients mouth. 12) Demonstrate rubber cup on patients fingernail. 13)Holding the patients hand promotes relaxation. 14)Since strong taste may be rejected use smaller quantities of dental materials with such characteristics. 15)Explain the procedure of oral hygiene and then place the patients hand on yours as you slowly guide the tooth brush. 16)Use audiocassettes for explaining specific dental procedures and decrease chair time. 17)Avoid unexpected loud noises. 18)Limit the dental care to one dentist. Down’s Syndrome Synonyms – Mongolism, Trisomy 21 It is one of the most common chromosomal disoders. Etiology Chromosomal abnormalities is Trisomy 21 or presence of extra autosome (Thompson 1973).

Following considerations: 1) Pulp therapy for primary teeth is not recommended – therefore, increase incidence of chronic infection – extrusion and SM. 2) Endo therapy – in permanent teeth can usually accomplished and performed adequately. 3) Patients with cardiac pacemakers with existing congenital defect or disease prophylactic antibiotic coverage to prevent SABE is not indicated. HEMOPHILLIA This is most common congenital blood coagulation disorders which produces serious bleeding episodes. This is caused due factor VIII (A) deficiency and factor IX (B) deficiency. Hemophilia is inherited as an X linked recessive tract. Therefore all males who possess the defective X chromosome have clinical manifestations of disease and females are caries. Another bleeding disorder, frequently confused with hemophilia is Von Willebrand disease. This disease is inherited via autosomal dominant gene affecting males and females. The person with this disease have mild deficiency of factor VIII and abnormal platelet function.

Dental management of hemophilia The dental treatment of a patient with hemophilia necessitates thorough understanding of this patients disorder. It is important that the nature of disorder be determined through interviews with parents and childs physician. Before starting the treatment, the dentists should undertake thorough medical history about this disease. It is especially important to avoid tissue laceration or other intraoral trauma. The following patients are important in treating the patient. 1) The relief of anxiety has been shown to be beneficial in maintaining hemostasis â&#x20AC;&#x201C; by premedication, nitrous oxide inhalation, hypnosis. IM transquilizing analgesic agents in contraindicated as it can cause hematoma. 2) In absence of factor replacement, intraligamental injection may be used. Block anesthesia is not recommended, local infiltration can be easily administered after single infusion of factor replacement.

38


3) Teeth can be cleaned by rubber cup minor haemorrhage can be controlled with local mechanism such as direct pressure. For minor hemorrhage topical application of bovine thrombin may be used. 4) Most of restorative procedure and pulp therapy on deciduous teeth can be successfully completed without discomfort through use of acetaminophen with iodemic with nitrous oxide inhalaton. Hemophilia If the child with hemophilia sustain oral trauma with excessive bleeding following modalities. 1) Hemorrhage associated with laceration of OMM – single dose factor cocnentrate that raises the level of factor 50% of normal E-ACA continued until epithelization is complete. 2) Laceration which requires suturing repeated doses of factor which level of at least 25% of normal is maintained E-ACA infusion continued until the wound is healed. 3) Extraction of primary teeth or permanent, factor VIII infusion of 100% of normal and loading dose of E-ACA maintenance dose of E-ACA for 7 to 10 days. Extraction of teeth begin within 1 hour after infusion. Adjunct local measures to control bleeding should be considered. Like avitum or oxidized cellulose material impregnated with bovine thrombin. Patient must be give very specific instruction – strict diet for 2 weeks – 1st 22 hours liquid diet. Dairy products should not be allowed as they leave film residue. Next week soft diet after 10 days – normal diet.

39


E-amino caperi acid (E-ACA) As adjunct to factor replacement therapy. In hemophilic patient, there is normal Fibrinolytic mechanism but generation of thrombin necessary for clot is decreased. Thus, the clots get dislodged. The fibrinolytic mechanism is inhibited by E-ACA to form stable clots. Desmopressin acectate -

Antidiuretic hormone â&#x20AC;&#x201C; causes increased levels factors VIII.

4) Particular care must be taken in placement of IOPA films and use of high suction or saliva ejector. 5) The use of rubberdam with greatly assist in protection of soft tissues clamps with subgingival extension should be avoided. 6) Conventional pulp therapy is preferable to tooth extraction. Intrapulpal injection can be used to reduce pain. Hemorrhage from pulp chamber can be reduced by pressure packs. Dental care Preventive Dentistry Prevention of dental diseases requires a combination of diet, plaque control regular continuing professional care. Parents should be made aware that as gingival health improves, minor bleeding caused by brushing will stop or treated by topical bovine thrombin. Flossing should be taught only to those parents and patients who appear capable of mastering the techniques. In severe hemophilias, fluoride therapy, to be done every 3 months using custom trays.

40


Periodontal disease Treatment of the periodontium is one of the most neglected aspects of children. Simple dental prophylaxis and topical fluoride application can be easily done in severe hemophiliases provided meticulous care is exercised to prevent gingival trauma. Calculus may be removed in stages in order to reduce bleeding risk. Initially, gross supragingival scaling is done, allowing the gingival inflammation to subside, as the inflammation resolves remaining calculus can be removed. For deep scaling, replacement therapy should be used prior to the treatment. Restorative Dentistry Extra care should be taken to avoid soft tissue injury. Routine use of rubber dam is helpful in protecting patients lips and tongue from trauma, clamps such as ivory No. 8A and 14A should be avoided for gingival damage, clamps such as SS white No.22. 201. Extra care must be taken during passing the rubber dam through contact points with dental floss to avoid â&#x20AC;&#x153;snappingâ&#x20AC;? of floss into interproximal gingiva. Stainless steel crowns can be avoided when possible to prevent gingival bleeding and laceration. Endodontic procedures These are highly recommended in children to lower the need for extaction. Pulp bleeding can be controlled easily without replacement therapy. Extra care is taken to prevent periapical trauma. 41


Oral surgery Prior to surgical procedures, missing blood factor is replaced. During extraction procedure. Lucas and others advocate combination of absorbable hemostatic agents and topical bovine thrombin. Lucas, saturates oxidized regenerated cellulose with bovine thrombin dissolved in 0.5% sodium percarborate solution. After socket is dried, surgicel is used to fill the socket within 1 mm of the surface lucas then covered the wound with splint. Orthodontics Although bands should be avoided when possible, much can be done with adhesive brackets or removable appliance in orthodontic management of malocclusion. In severe bleeders however, it is not suggested that bands be used on any teeth. AUTISM In 1944 Kaner described clinical syndrome in children to which negave name infantile autism. He described that one symptom with the disease was an viability to relate approximately to the people and situations. These childrens are seem to be self sufficient and introverted and want to be left alone. -

They have no attachment to parents.

-

They relate poorly to persons.

-

They remain occupied water moving or shining objects such as keys, spinning tops for hours.

Cleft Lip and Palate Cleft lip with cleft palate is severe birth defect occurring in newborn infants. Cleft lip and cleft palate are among common congenital malfunctions occurring in orofacial region. The variable morphology of the congenital anamoly ranges from soft tissue defect involving either lip or soft palate with complete separation of the oral and nasal cavities. The associated defects with this are malformed teeth, malocclusions, impairment of speech, middle ear infection, URTI. Incidence -

One in 750-1000 newborns in USA.

-

In whites â&#x20AC;&#x201C; one is 800 births.

-

In blacks â&#x20AC;&#x201C; one in 2000 births.

-

Japanese - one in 500 births.

44


-

Cleft lip and palate lengthen account for 50% of all cases.

-

Isolated cleft lip and palate occur in 25% each.

-

Males are commonly affected. A number of classification have been proposed but one of them have

been universally accepted. I)

Davis and Ritchie (1922)

Group I – Prealveolar clefts – lip clefts only with unilateral, median and bilateral. Group II – Post alveolar clefts – involves soft and hard palates. Group III – Alveolar clefts – complete clefts of palate, ridges and lip. II)

Fitz and Gibbon (1930) 1) Cleft of the soft palate. 2) Cleft of soft and hard palate. 3) Cleft of the soft and hard palate with single hard lip. 4) Cleft of soft and hard palate, with double hairlip and deteched premaxillae. 5) Cleft of soft and hard palate, edentulous.

I)

Vean (1931) classification of cleft lip and cleft palate a)

Cleft lip

Class I – unilateral notching of vermillion border but not extending into the lip.

45


Class II – unilateral notching of the vermillion border with cleft extending into the lip but the floor of the nose. Class III – unilateral cleft the vermillion border of the lip, extending into the floor of the nose. Class IV – Any bilateral cleft lip whether this be incomplete notching or complete clefting. b)

Cleft palate

Class I – involves only the soft palate. Class II – involves only the soft and hard palate, but not alveolar process. Class III – involves both soft and hard palate and the alveolar process oneside of the premaxillary area. Class IV – involves the soft and hard palate and continues through the alveolus on both sides of premaxilla, leaving a free and mobile.

46


III)

Fogh – Anderson (1942)

Group I – Harelip – single, double Group II – Harelip and cleft palate – single, double. Group III – Cleft palate IV)

Olinger classification (1952)

Class I – fissure in azygos uvuale Class II – Fissure in uvuale Class III – Fissure in soft palate Class IV – Fissure in soft and hard palates. Class V – unilateral cleft, fissure in the soft and hard palates, then alveolar ridge at junction of maxilla and premaxilla accompanied by cleft lip. Class VI – bilateral cleft, fissure in soft and hard palates through the alveolar ridge at the junction of the maxillae, accompanied by cleft lip. V)

Kernahan and Stark (1953) This pattern is widely accepted and utilized.

Group I – (clefts of primary palate anterior to inclusive foramin)- Cleft of the tip (CL), all forms of degrees of cleft lip, and combination cleft lip and cleft alveolar process. Group II – Cleft lying posterior to incisive foramin on degrees of clefts of soft and hard palates. Group III – Combination of clefts of both primary and secondary palates involves combination of group I and group II.

47


Subdivision Group I 1) Unilateral cleft lip – incomplete 2) Unilateral cleft lip – complete Group II 1) Cleft lip involving the soft palate only. 2) Cleft lip involving the soft palate and hard palate. Group III 1) Unilateral cleft lip with complete cleft of soft and hard palate. 2) Bilateral cleft lip with complete cleft of soft and hard palate. VI)

48


Etiology Extent etiology of CCP is still unknown but few accepted theories. 1) Exogenous tract factors Like – Rubella Thalidomide drugs 2) Mulant genese and chromosomal aberration. Mutant genes – ectodermal dysplasia Chromosomal aberrations – D-trisomy and E-trisomy 3) Multifactorial causes Contribution of both with heredity. Pathogenesis Cleft lip According to mesodermal deficiency theory the lip and premaxilla in their early forms as an ectodermal good in which 3 masses of mesoderm are present. Normally these masses grow and limit to form the upper lip and premaxilla, but failure of the growth leads to infiltration of the ectodermal head a consequent weakening of this delicate membrane induces a rupture of the head and a cleft lip results. Cleft palate This commonly accepted that cleft palate results from the failure of the palatal shelves to meet and fuse in the midline.

49


Causes are: 1) Failure to displace the tongue from between the shelves may prevents closure. 2) Fusion may be prevented because shelves are too narrow to meet in the midline or because of other structural defects. 3) Normal palatal shelves may not meet in the midline is an individual ha an incisally wide head.

If present eyes to gene therapists, so that etiology and mech can be explained. Other consultation should be addressed depending on the physical

examination by EMT, opthalmologist, cardiologist, pediatrician prior to surgery. Also refer the child to psychologist, speech pathologist, radiologist. Pre surgical management (counseling) It is extremely important because almost all the patients have same concerns. This will help the parents to warmup. Feeding First goal is to prepare the child for surgical response of lip. Before surgery the child should have following criteria – 10 weeks, weight 10 pounds and 10 gms of tbl spoon – ‘3 times law’. Feeding plates Feeding problems arise in the case of bilateral and unilateral cleft. A feeding plate can be made to cover the roof of the mouth to prevent food entering nasal cavity.

51


Stage (maxillary orthopedic stage) birth to 18 months Feeding problems are often associated with clefts, making it difficult to maintain adequate nutrition. -

Insufficient suction to pure milk excessive out intake, nasal discharge.

McNeil (1950) â&#x20AC;&#x201C; Obturator Advantages 1) Provides false palate against which the infant can suck reducing feeding problems. 2) Provides maxillary cross arch stability and prevents arch collapse. 3) Orthopedic moulding cleft segments in to approximation before bone grafting.

Recall every 15 to 1 month. The primary function of cleft palate clinic are to evaluate and

planning of rehabilitative needs of his patient. To obtain optimal rehabilitation each number of the discipline involved have general problem faced by other members of the team, is excessive and prolonged orthodontic treatment required in separate stages: 1) Infancy before initial surgical repair of lip. 2) During primary and mixed dentition stage. 3) During late mixed dentition and early permanent dentition stage. 4) In later teeths after the complication of facial growth in conjunction with orthognathic surgery. Infant Orthopedics If presurgical movement is indicated it is carried out 3 to 6 weeks of age that lip closure can be carried out 10 weeks. A passive plate similar to orthodontic retainer is used for months after lip closure.

53


Later primary and early mixed dentition treatment The result from surgical correction of lip closure some constitution across the anterior parts of maxillary arch is created. Orthodontic intervention is often unnecessary until permanent incisors begin to erupt. There is tendency that maxillary anterior erupted rotation and with crossbite. This can be corrected by fixed and removable appliance. Pre-surgical orthopedics: The growth potential of the nasal septum is extremely powerful when the lip is normal, the forces are directed anteriorly along the midline. If there is a muscle pull to one side because of a unilateral cleft these two forces combine to pull the major segment to non cleft side. Therefore if an opposing force to nasal septum and to the muscle pull can be applied the distortion can be minimized. If at the same time a shearing force can be applied to minor segment, the major and minor segments of the alveolus and lip can pulled together. This makes the task of plastic surgeon repairing the lip defect much easier. The active force can be provided by 3 pieces of tape joined together by 2 elastic bands. The central portion of the tape tends to cup the premaxilla in bilateral cleft case thus stabilizing the segment strapping should be applied immediately after birth and continue till the time of surgery. In this way tension in the tissues is minimized version facial skin as the repeated changing of the strapping

54


means that the tape must be removed from the face this can result in the skin becoming sore using a barrier dressing or leaving an additional piece of tape on the face minimizes the effects of this recurrent trauma. In the case of bilateral clefts, the lateral segments tend to approximate, resulting in the blocking out of the premaxilla. To prevent this an oral plate must be fitted to stabilize or even move the lateral segments buccally when the cleft of palate is unilateral, an active plate can be used to stabilize or prevent collapse of the segments and narrowing of the maxillary arch. One type of expansion plate is constructed on a cast that has been cut and the segments reposition by upto 3mm. Alternatively a plate with a spring in the anterior region and a hinge in the posterior region can be fabricated to give a differential expansion. An active plate unlike the passive feeding plate must be worn at all times. This plate is kept in position by the action of the tongue, the force generated by the baby acting together an extraoral were â&#x20AC;&#x153;whiskersâ&#x20AC;? which are taped to babys face. Orthodontics The goal of orthodontic treatment is to provide an aesthetically acceptable and healthy dentition for life and to contribute positively to the

55


general facial form and appearance. An orthodontist working with clefts, children before starting treatment two important parameters. 1. First with regard to the timing of orthodontic treatment. 2. Most patients have complex orthodontic problems dental problems specific to cleft and palate. 1.

Congenitally missing teeth. It has shown that children who have clefts of the maxilla have a

higher incidence of congenitally missing teeth. This is true not only the immediate area of cleft but also the contralateral side and the opposing arch in complete unilateral clefts. 2.

Supernumerary teeth A greater incidence of supernumerary teeth in the cleft lip and palate

patient. The maxillary lateral incisor area is affected most often, especially when it is in the direct line of the cleft. When cleft occurs it affects the angle of the lateral incisor and can split it in two. The teeth are ectopic in position smaller in size and expandable. 3.

Other tooth anomalies

These include: a. Fused.

56


b. Irregularities of tooth size, ectopic eruption, malformation of individual teeth delayed eruption of mandibular teeth ankylosis of teeth adjacent to the site of the cleft lack of bony base over which teeth might be moved. Presurgical period When pre-operative orthopedic treatment was introduced at many clefts center in 1950â&#x20AC;&#x2122;s. The above principles and objectives its adoption was resisted for the following reasons: 1. The surgeons felt they did not need it. 2. At the time pre-surgical orthopedic treatment was introduced. 3. The teem particularly the orthodontist were worried that pre-surgical orthopedics may have a adverse effect on maxillary growth. Pre surgical orthopedic treatment has now been used extensively in Europe and limited states for over 30 years. Treatment Procedures Orthodontic care is considered here in 3 phases, during the primary, mixed and the permanent dentition.

57


Primary dentition phase The extent of a malocclusions is usually lees apparent in the primary dentition. Then in the permanent dentition, treatment is difficult in the primary dentition because of the lack of good teeth for anchorage. -

The presence of a bulky appliance in the mouth may contribute to speech problems.

-

The level of cooperation that can be expected from a child of this age is fairly limited.

-

In addition as children grows relapse commonly occurs.

Even when there is evidence of a high arching palate due to lateral collapse or retrusion of the maxilla it is usually better not to perform any active treatment in the primary dentition. Mixed dentition phase By the mixed dentition stage most of not all of the anterior teeth in the region of the cleft will have erupted. They are frequently malformed, hypoplastic and erupt in ectopic positions or missing the rationale of treatment was to reduce cross bites and create functional environment. As a general rule orthodontic treatment during the mixed dentition limits itself maxillary arch.

58


For example in complete, unilateral and bilateral clefts if buccal segments crossbite exists to reduce the first. If the maxillary central incisors erupt in lingual version or rotated and ectopic. This requires another phase of treatment. If the maxillary first permanent molars erupt in crossbite and lateral incisors in lingual version, this to necessitates, additional treatment. There are number of techniques available for reduction of bilateral buccal crossbites. 1. Quad helix appliance. 2. A rapid maxillary expansion device. Permanent dentition phase By the permanent dentition stage growth is nearing completion and magnitude of any deformity can be readily assessed. Hence this is the most appropriate time for performing orthodontic therapy. There may be abnormalities in the position of the teeth or the jaws. In the case of later the discrepancies can be considered in 3 planes: 1. Transverse. 2. Anteroposterior. 3. Vertical. The transverse relationship may be such that a posterior crossbite. This is usually more in the region of the minor segment adjacent to the

59


cleft. The collapse of the arch may be due to repair of the lip. It is more due to scar tissue arising from the palatal repair which has restricted lateral maxillary growth. Because of the lack of bony union between the segments of the maxilla, they can be easily moved using a fixed appliance that is cemented directly to the teeth. This approach limits the degree of tooth tipping. When there is a severe anterior cross bite, expansion may be required using a roped palatal expansion type of appliance. For correction of a posterior crossbite, a quadhelix type of appliance is used. There is no midline suture to open in posterior region, this expansion can be performed more slowly. An alternative is an appliance that caps the teeth and has a screw anteriorly and a hinge posteriorly to achieve differential expansion of the arch. Speech and language All children with cleft palate requires such therapy to overcome the difficulties associated with trying to generate intraoral pressure and to overcome hyper or hyponasality. In the time between repairing the lip and palate, the child begins to develop oral movements before speech. This is pronounced between 12-18 months of age. Repair of the palate should not be delayed beyond this period because in the majority of cases acceptable speech can be achieved following surgery at this stage. 60


Immediately after birth, the child will start to experiment with sound production. These early babblings are the beginning of speech. The speech therapist can advise the parents to encourage the child by reading to them and naming objects when moving around the house or in the street. All times it is essential that the child is allowed to practice speaking. The parents need to be counseled by a speech therapist so that they fitting palate in the childs mouth on a long term basis before palatal repair may have some beneficial effects in that it allows the tongue to function in an area approximating to the shape of the future mouth. Multispeciality team management White house had described, clinical team as a close cooperative democratic, multiprofessional lenion development to a common purpose the best treatment of fundamental needs of a patient. In order to improve function and appearance of various parts of face and oral cavity that are affected by this defect and associated psychological problems, different specialists must work in close collaboration to treat these children. The team include a plastic surgeon, a pedodontist an ENT surgeon an orthodontist, a speech therapist, oral surgeon and a prosthodontist. The role of individual specialists Primary function of plastic surgeon is to prepare clefts of lip and palate and to improve function of the soft palate and appearance of lip and

61


nose. He may be required to deepen the labial sulcus and in bilateral cleft cases, reposition the premaxilla. Because of early treatment performed by plastic surgeon, parents become acquainted with him and he makes a useful team leader. The pediatric dentist is responsible for constructing feeding plates and advising parents on feeding techniques for the neonate. He provides restorative and preventive dentistry including dietary advice and topical fluoride applications during childhood. The ear, nose and throat surgeons performs aural examinations and assesses the hearing by using impedance and compliance tests. This is essential if the child is to communicate and learn at the normal rate. If necessary surgical procedures can be used to protect ears and maintain them in a healthy state, the role of ENT surgeon is limited after the age of 7 years because most of early hearing problems should have ceased. Hearing improves when the tensor palati muscles take over from levator palati muscle as the primary muscles responsible for opening the Eustachian tube. The orthodontist is usually responsible for performing presurgical dental orthopedics and when necessary early correction of malalignment in the incisions and correction of discrepancies in the labial segment relationship. Crowding and malalignments are corrected in the full

62


permanent dentition and teeth are often moved orthodontically to move favourable position for the retention of a prosthesis. The speech therapist advises the parents about communication problems and demonstrates method of encouraging the child to speak properly. When necessary treatment is provided to overcome problems such as hypernasality, nasal fricatives defects articulation due to inability of patient to build up sufficient pressure. The social worker can help by giving support advice and looking after many siblings. Prosthodontist replaces, restores orofacial structures that may be congenitally missing or malformed non living materials are used to restore, enhance form and anatomy he fabricate appliance to rehabilitate mastication deglutition, speech and oral esthetics. They may incorporate a palatal expansion or an obturator to occlude any residual palatal defect. The psychologist assists by counseling both parents and child at different times to help them, minge and cope with their problems. The oral and maxillofacial surgeon evaluates all patients for facial form and function and jaw position many cleft patients have a skeletal malocclusion that can be treated by conventional orthodontics and requires surgical correction. The surgical placement of primary and secondary alveolar cleft bone graft is another important role of the surgeon. These 63


grafts aid in dental rehabilitation of the patient. The grafted bone supports the teeth adjacent to the cleft site and provides bone through which teeth may except. Treatment schedule summary and the specialists treating a patient with a cleft lip and palate: Birth : Pedodontist may construct feeding plate and initiate pre-surgical dental orthopedics. Team members are introduced to parents and emphasize need for adequate weight gain so child attain necessary stage of development before lip surgery. 3 months of age- surgical repair of lip bilateral cleft lip cases may be repaired as a two stage procedure. 6 months â&#x20AC;&#x201C; preventive dentistry begins. 15-18 months surgical repair of palate speech therapist assess. 2 years â&#x20AC;&#x201C; plastic surgeon review surgical result orthodontist examines teeth and soft tissues, especially noting relationships of anterior segments and depth of labial sulcus in the cleft region. ENT surgeon assesses hearing and examines tympanic membrane speech therapist continue to monitor speech. Pedodontist stresses importance of good dental health. 3 years â&#x20AC;&#x201C; dental check ups at 4 months intervals other team members review regress annually.

64


4 years – ENT surgeon usually performs aduiography and compliance tests and if necessary places grommet tubes in ear drums. Speech therapy starts for children with speech and hearing problems. 7 years – Early correction of malalignment of an anterior teeth and labial segment relationship. 9 years – surgical lip and nose revision to improve appearance. 12 years – orthodontists correct malocclusion and treats crowding and malalignments. Expansion of maxillary arch may be necessary teeth may be moved so as to create space for bone graft or for fixed removable prosthesis. 16 years – plastic surgery to improve the appearance of nose, the oral surgeon may form a Lefort 1 maxillary osteotomy to correct retrusive appearing maxillo, replacement of missing teeth with fixed bridge or removable prosthesis. 16 years onwards – prosthodontists and restorative dentist prove regular dental care. Dental management of the cleft patient The child patient with a cleft lip and palate offers challenges to the pediatric dentist. The children undergo surgical and dental procedures more frequently making them more anxious in the dental office. Change in the

65


innervation of the maxilla and post surgical scar tissue make the local anesthesia difficult the anesthetic scar from missing teeth an incomplete alveolus also managed until the establishment of the permanent dentition. As part of a cleft palate team and pediatric dentists mission is to protect and supervise. The eruption of permanent teeth. The tasks that one can be expected to perform include the following: 1. Construction of infant feeding and orthopedic appliances. 2. Education of parents to the dental needs and care of this child. 3. Introduction of the child to environment. 4. Prevention of dental caries. 5. Guidance of the developing primary and secondary dentition. 6. Restorative dentistry for the primary and secondary dentition. 7. Management of problems unique to the cleft side. 8. Education of the child and parents to the maintenance of good oral hygiene. Establishing good communication between the child and the dentist is the first step in helping the child develop a positive attitude towards the dental office experience. Home rinses can be used for the child who wears an orthodontic and prosthodontic appliance.

66


As the permanent teeth erupt, those teeth with a deep pit or fissure should be considered for occlusal sealants. Local Anesthesia The use of local anesthesia is an important factor in the successful development of pediatric dental care. The tissue over the injection site is implied with a dry gauze and a cotton tip applicator dipped in a topical anesthetic is applied to the injection site. 20% Benzocaine is the most common topical anesthesia used. It has an onset of action of 30 seconds. Oral surgery A common problem with infiltration anesthesia in the cleft population is the anesthetizing a tooth in or near the cleft area. Usually the tissue surrounding the tooth is tightly bound down and prevents infiltration of anesthetic for these teeth injection of the anesthetic into the periodontal space is recommended. A special syringe for this injection prevents breakage of the anesthesia catridges, due to the higher injection pressure is required. This technique is useful for the extraction of supernumerary maxillary teeth. Preventive and Restorative Dentistry As a rule initial visit to the dentist is made when the patient is between 2 and 3 years old. At this time deciduous dentition is developing and surgical closure of the clefts have been completed one of the first few 67


visits child should be examined receive light prophylaxis, allowed to familiarize himself with dentist and his surroundings because of shape of surgically treated palate some difficulty may arise in taking radiographs. However it is essential that these diagnostic aids to be obtained approximately 4 years of age of four years for detection of caries and determination of supernumerary congenitally missing or malformed teeth. The caries rate is patients with cleft lip and palate is theoretically same as for any other patient. However, the use of intraoral appliances for long periods increases caries susceptibility to monitor the oral health care more frequent recalls at 3-4 month intervals are necessary professional applications to topical fluorides must be given regularly pit and fissure sealants must used on all permanent teeth and in the primary dentition in selected cases.
