A CLINICAL EVALUATION OF ALKALINE PHOSPHATASE ACTIVITY IN GINGIVAL CREVICULAR FLUID DURING HUMAN ORTHODONTIC TOOTH MOVEMENT

www.indiandentalacademy.com


Need for the study: The early phase of orthodontic tooth movement involves an acute inflammatory response. The mechanism of bone resorption might also be related to the release of inflammatory mediators that can be detected in gingival crevicular fluid. Moreover orthodontic force involves an increased proliferation and differentiation of the cells of the periodontal ligament into osteoblasts. In recent years, a number of gingival crevicular fluid constituents have been shown to be diagnostic markers of active tissue destruction , but only a few studies have focused on the GCF constituents involved in bone remodeling during orthodontic tooth movement. www.indiandentalacademy.com


Uematsu et al found that during orthodontic treatment, the levels of different inflammatory mediators in GCF that is interleukin 1β , interleukin 6, TNF ι , epidermal growth factor, and β2 microglobulin, underwent significant elevations. Bone forming cells have been shown to have alkaline phosphatase activity and changes in this enzyme in serum and bone have been used as markers for bone metabolism. This longitudinal study will be done to assess GCF alkaline phosphatase activity during orthodontics treatment in human subjects as it relates to the time of treatment and the type of stress exerted on the periodontium by tooth movement. www.indiandentalacademy.com


Materials and Methods: Source of Data: 10 orthodontic patients will be taken who need premolar extraction and canine retraction with Hycon retraction screw as part of orthodontics treatment. The patients will be undergoing orthodontic treatment in Department of Orthodontics and Dentofacial Orthopedics, College of Dental Sciences, Davangere.

Methods of Collection of the Data: Criteria for Selection of Patients: •Patients who need premolar extraction and canine retraction as part of their orthodontic treatment. •Good general healthwww.indiandentalacademy.com


•No use of anti inflammatory drugs during the month preceding the study •Pocket probing depth values not exceeding 3 mm in the whole dentition. •No radiographic evidence of periodontal bone loss Materials Required: •Micropipette •Spectrophotometer Method: Gingival crevicular fluid will be collected immediately before appliance activation, 1hour after, and weekly over the following 4 weeks and alkaline phosphatase level will be assessed www.indiandentalacademy.com using spectrophotometer.
