MyDentist opens its 50th clinic in Kharghar MyDentist, India's largest dental clinic chain inaugurated its 50th dental clinic in Kharghar. MyDentist also announced the introduction of new initiatives that will help the dentists at the clinic, detect and manage oral cancer at an early stage.
hey have Introduced the low cost oral cancer detection tests. While speaking to a local daily they reported that "Their focus will continue to be on providing best quality dental care techniques." MyDentist treats over 10,000 patients every month. It has been observed that a number of patients develop oral/dental problems because of the habit of chewing or
smoking tobacco. A recent report prepared by experts of National Institute of Health and Family Welfare (NIHFW) had indicated that India alone accounted for 86% of the total oral cancer figure across the world. Chewing tobacco and gutka contributes to 90% of oral cancer cases in the country.
The doctors at MyDentist have been instrumental in spreading awareness about
the impact of usage of tobacco. MyDentist, the operative brand name for the company Total Dental Care Pvt Ltd (TDCPL), was incorporated by Vikram Vora in 2009 and was incubated by Seedfund in 2010. It received its first round of funding from Seedfund in 2011.MyDentist raised Rs50 crore as Series B
in April from Seedfund and Asian Healthcare Fund. MyDentist used this fund to establish itself in the market and grow its chain to 50 clinics across Mumbai and Pune. In less than 3 years time, it has served over 1,20,000 patients making it the largest dental care chains in India. As of May, it had a team of 400 employees inclusive of 200 doctors.
MCIeases norms forMBBS studies abroad Hyderabad: Students who want to study MBBS abroad will no longer need to obtain eligibility certificates from the Medical Council of India. Due to severe shortage of MBBS seats in the state, nearly 10,000 students from AP opt for medical colleges in China, Russia, Central America, the Philippines among others every year. There are only 6,200 MBBS seats in the state for which over 1 lakh candidates compete in amcet. Getting the degree in these countries is relatively cheaper. A student can complete MBBS
abroad in less than Rs 30 lakh. In the state, the student has to pay, apart from the fee, a donation of up to Rs 80 lakh to get a seat in management quota. All this totals to Rs 1.5 crore reported the daily. But students wanting to study in these countries had to obtain an EC from the MCI, which was an ordeal taking several months. The MCI had to obtain data from the Board of Intermediate Education and the SSC Board to verify the studentsâ€™ age and educational qualifications for doing their MBBS abroad. Most students turned to brokers to get the work done quickly. Those who took admissions directly
without obtaining the EC were barred from appearing for the MCIâ€™s "screening test". which these students have to mandatorily clear to be eligible to practice in India. The daily also published a public notice issued by the MCI which states: "Indian citizens who intend to acquire primary medical qualification from any foreign country on or after 15 May, 2013, are not required to obtain the Eligibility Certificate from the Medical Council of India. However, they are required to fulfill the eligibility criteria for admission to MBBS course as laid down in the Graduate Medical Education Regulation, 1997."
Dental and Medical Admission Test: Scamsters operated in Cyber Cafes BHOPAL: As per the published news in a leading English daily which exposed a dozen gangs that were busted for duping medical aspirants of crores of rupees in exchange of getting them seats in private medical and dental colleges of the state through the Dental and Medical Admission Test
(DMAT) operated from internet cafes to college premises. The accused used to introduce themselves to aspirants as personal assistants of college directors, doctors and claimed to have influence in DMAT office - the body which conducts exam for private medical colleges in M.P. One of the Accussed
arrested after the first FIR of forgery was registered at the Kolar police station on September 7, used to lure victims claiming that he is the personal assistant of the director of LN medical college reported the daily. Similarly,
the incident wherein a Nainitalbased person, who was duped of Rs 16 lakh for a medical seat for his nephew, claimed that he was approached by an imposter, through internet who claimed

that he is handicapped and is based at Guwahati. The newspaper reported that the Police said the busted gangs would claim to have influence in DMAT office. It has even come to light that students would get the exact numbers in DMAT exam they needed to get medical seats in the private colleges
where they wanted to take admissions.Police officials are in the process to ascertain how the marks of a student were managed through the DMAT exam. In total six interstate gangs involved in forgery of medical seats worth around Rs 3 crore have been busted by the police so far.

Fully Functional Bioengineered Salivary Gland The research group led by Professor Takashi Tsuji of Tokyo University of Science and Organ Technologies Inc. has provided a proof-of-concept for bioengineered mature organ replacement as a regenerative therapy. Current advances in regenerative therapies have been influenced by the study of embryonic development, stem cell biology, and tissue engineering technologies. The ultimate goal of regenerative therapy is to develop fully functional bioengineered tissues that can replace lost or damaged organs following disease, injury or aging. A research group led by Professor Takashi Tsuji (Professor in the Research Institute for Science and Technology, Tokyo University of Science, and Director of Organ Technologies Inc.) has provided a proof-ofconcept for bioengineered mature organ replacement as a regenerative therapy. Dr. Tsujiâ€™s research group (M. Ogawa et al.) reports the fully functional regeneration of a salivary gland that reproduces the morphogenesis induced by reciprocal epithelial and mesenchymal interactions through the orthotopic transplantation of a bioengineered salivary gland germ as a regenerative organ replacement therapy. The bioengineered germ developed into a mature gland through acinar formations with the myoepithelium and innervation. The bioengineered submandibular gland produced saliva in response to the administration of pilocarpine and gustatory stimulation by citrate, protected against oral bacterial infection and restored normal swallowing in a salivary gland defect mouse model. Thus, this study provides a proof-of-concept for bioengineered salivary gland regeneration as a potential treatment for xerostomia. This research was performed in collaboration with Professor Tetsuhiko Tachikawa (Department of Oral Pathology, Showa University School of Dentistry, Shinagawaku, Tokyo, JAPAN). Salivary glands play essential roles in normal upper gastrointestinal tract function and oral health, including the digestion of starch by salivary amylase, swallowing and the maintenance of tooth hard tissues through the production of saliva. There are three major salivary glands -- the parotid, submandibular and sublingual glands -- as well as minor salivary glands. Salivary glands are composedof duct, acinar, and myoepithelial cells.
The disease of salivary gland. One concept that may be applicable for restoring salivary glands is regenerative therapy, which involves tissue stem-cell transplantation to restore damaged tissues and organs in a variety of diseases. Furthermore, organ replacement regenerative therapy, which can replace lost or dam-
aged organs with a fully functional bioengineered organ, is also expected to provide a novel therapeutic strategy for organ transplantation. The study demonstrated that each bioengineered salivary gland germ, including the submandibular and sublingual glands, had the potential to regenerate into mature glands using researchers previously developed organ germ method. After three days in organ culture, all of the bioengineered salivary gland germs underwent branching morphogenesis, followed by stalk elongation and cleft formation.
Engraftment of a bioengineered salivary gland Saliva, which is produced from serous- and mucous-type acinar cells, plays essential roles in oral function. Histological analysis using haematoxylin and eosin (HE) staining and periodic acid and Schiff (PAS) staining revealed a distinctive acinar structure, including serous acinar cells, in the bioengineered submandibular gland and mucous acinar cells in the bioengineered sublingual gland. E-cadherin and calponin proteins were detected in the acinar and duct cells as well as in myoepithelial cells, which enveloped acinar cells in these bioengineered glands. Innervations were also detected in the interstitial tissue among acinar cells, and neurofilament H (NF-H)expressing nerve fibres connected to calponin-positive myoepithelial cells. The research demonstrates that engrafted bioengineered salivary gland germ cells successfully formed correct tissue structures and could secrete saliva in response to neural stimulation.
Functional analysis of bioengineered saliva secretion Saliva secretion is essential to the maintenance of oral health, and xerostomia causes various health problems, including dental caries, periodontal disease, bacterial infection and swallowing dysfunction. To semiquantitatively analyse saliva secretion,
the researchers performed fluorescein diffusion analysis. Briefly, fluorescent sodium test paper, which contains a fluorescent dye that dissolves in saliva drippings, was placed on the tongue. Dye diffusion was not observed during the observation period in the salivary gland defect mice. Gradual diffusion and disappearance of the fluorescein dye in the oral cavity was observed in mice transplanted with the bioengineered submandibular gland. The number of oral bacteria was drastically increased in salivary gland defect mice compared to normal mice. The number of bacterial colonies that formed in the mice engrafted with the bioengineered submandibular gland germ was significantly reduced compared to the number in salivary gland defect mice. These results indicate that the bioengineered submandibular gland has a cleansing function that prevents dryness and inhibits bacterial growth by secreting saliva into the oral cavity.
Functional recovery of swallowing and survival
CONCLUSION The research demonstrates the regeneration of fully functional salivary glands through the orthotopic transplantation of a bioengineered salivary gland germ in adult mice. The bioengineered submandibular gland, which was transplanted using an inter-epithelial tissueconnecting plastic method, produced saliva in response to the administration of gustatory stimulation by citrate, protected against oral bacterial infection and restored swallowing in a mouse model of a salivary gland defect. Thus, this study provides a proof-of-concept for bioengineered salivary gland regeneration as a potential treatment of xerostomia. Further studies on the identification of stem cells as a source for the reconstitution of bioengineered salivary gland germs are warranted.

High-Dose Statins Reduce Gum Inflammation in Heart Disease Patients
Statins, commonly prescribed medications for lowering cholesterol, also reduced inflammation associated with gum disease in a new study published in the Journal of the American College of Cardiology. The study suggests that steps taken to reduce gum disease may also reduce inflammation in the arteries and vice versa. "Periodontal disease is characterized by chronic gum inflammation and affects approximately 50 percent of the U.S. adult population," explains Ahmed Tawkol, MD, co-director of the Cardiac Imaging Trials Program at Massachusetts General Hospital and Harvard Medical School and co-author of the study. Periodontitis and atherosclerosis are both primarily driven by inflammation. These inflammatory conditions tend to co-exist within individuals and their biologies may be intertwined. In the double-blind, randomized study, patients with heart disease or a high heart disease risk were assigned to take either an 80 mg statin or a 10 mg statin daily for 12 weeks. PET/CT scans were collected after four and 12 weeks and compared to scans taken before treatment began. The 59 patients included in the final analysis showed a significant reduction in gum inflammation after as few as four weeks of treatment with the high-dose statin. Interestingly, the improvement in gum inflammation tracked closely with improvement in atherosclerotic disease. The study authors Cont d PAGE -11

Are Nanodiamond-Encrusted Teeth the Future of Dental Implants?

BASES OF ESTHETIC DENTISTRY
ESSENTIALS OFCOLOR CONCEPTS According to the Glossary of Prosthodontic terms,10 color can be defined as the quality of an object or substance with respect to light refected or transmitted by it. Color is usually determined visually by measurement of hue, saturation, and luminous refectance of the refected light. The three components of color are light source

Craniofacial Gunshot Trauma: A Case Study Approach
CRANIOROFACIALAND HEAD INJURY MANAGEMENT - RESIDENT'S PERSPECTIVE
Ideal management of patients who have underwent craniofacial trauma requires a collaborative interdisciplinary approach that involves the clinical expertise of a number of related specialties. This case study reveals the efforts and the contributions to an example of such type of trauma from eminent practitioners closely involved in the challenging care and management of patients who have required reconstruction of both acute and established injuries to the craniofacial hard and soft tissue. Craniofacial trauma due to Gunshot injuries is a challenging surgical emergency. In this case report we are discussing the whole aspects of managing a case with a compound orbitocraniofacial trauma due to gunshot injury. We are describing here the presentation, investigations and treatment, as well as the aim in managing such emergencies.
Everyday, men, women and children suffer head injuries. A car accident, a fall from height or sports injuries can range in severity from concussion to coma. Traumatic Brain Injury (TBI) can be fatal,dangerous and survivors, can show persistent problems that significantly affect their livelihood and well-being. India has the rather unenviable distinction of having the highest rate of head injury in the world. In India, more than 100,000 lives are lost every year with over 1 million suffering from serious head injuries, to be addressed by a handful number of craniofacial and neurosurgeons , as craniofacial neurosciences in India is new and rapidly expanding discipline and one has to be competent and razor sharp in applying its cognitive base and principles, and residency as is always described as an island in shades of grey, and in India it means higher pressure, higher stress loads, lesser patience, and longer quantum of time spent at work with sleepless nights and merciless bosses.
