Estimate Chronological age in Adult and Children Using Third Molar Development Stages.
Pak J Med Health Sci Jan ;12(1):576-8.

Background: In human body teeth are the most long lasting structure. In age determination of unidentified bodies the pattern of teeth development used as a credible technique. The last erupted teeth are third molars / wisdom teeth and regarded as most variable in dentition. For estimation of chronological age , development stages of third molar tooth growth used. Aim : To assess judgment of chronologic age based on the development stages of third molar growth . Methods: The cross-sectional study was carried out at Nishtar Institute of Dentistry, Multan from 16 .1.2016 to 20 .1.2018. Final sample consist of 600 orthopantomograms from young population of known chronologic age ranging 9 years to 26 years; mean age 15.94 +/-72 years and sex in which males were 260 with mean age of 15.53 +/- 3.75 year and 340 were females with mean age of 16.36 +/-3.89 year. Results: Between male and female third molar development showed the stages of calcification D&G p<0.05 significant difference statistically. Males were earlier attained genesis of third molar as compared to females. Strong association showed among age and growth of third molar for males r2 = 0.64 and r2 = 0.60 for females. For estimation of chronologic age, equation was derived age = 9.42+/-1.60 development stage. Conclusion: Third molar is suitable development marker particularly when comparing obtained standard deviation with other methods for calculation of skeletal age.
