Abstract

Introduction Dental identification is one of the main identification methods used for identification of a person’s age .With time , all the body parts start to decay but only the bones and the tooth are the only structures in the body that decay at a very slow rate.Estimation of age is one of the important  factors play a significant role in each aspect of life, including forensic medicine and dentistry, wherein race, age, and sex determination are used in person identification.

Aim The main objective of this study is to correlate the actual age of the individual with the staging of dermirjian  method for the Lower right mandibular third molar (48).

Materials And Method study samples consist of 100 randomly selected samples (50 males and 50 females) of age ranging from 10 to 21 years, population form children and adolescents and adults. Panoramic radiographs of these patients were evaluated based on Demirjian's method. The obtained data were tabulated and analyzed using SPSS and an independent t test was done.

Results: A total of 50 male and female OPGs were taken. For the male the p value was 0.554 and for the female the p value was 0.081, since the p value is 0.05 the results are insignificant and there is no correlation between actual age and staging.

Conclusion: The current study states that there is no correlation between actual age and staging for both male and female and it is concluded that the Demirjian method can be used in the Indian population with larger sample size for accurate results.
