Abstract
The present Study is based on orthopantographic evaluation of the development of the third molar (n=84 persons with known age between 15 to 25 years and known sex male-49, female-35) based on eight stages(A-H ) method of Demirjian et al. Data was feed in computer and analyzed using Statistical package SPSS. Regression analysis was performed to obtain formulas dental age calculation with chronological age. No Statistically significant difference was revealed in third molar development between males &female in all eight stages of development(p>0.05).No Statistically significant difference was revealed in third molar development between left &right side in all eight stages of development where both third molars were scorable (p>0.05). Statistical analysis showed a strong positive correlation between various stages of third molar development and chronological age (r > 0.60, p value<0.05). Regression formulas for whole sample based on the third molar teeth present were estimated and new equations derived:
Age in years =13.70+1.50(Developmental stage of Mx Right third molar)
Age in years = 14.82 + 1.25 (Developmental stage of Mn Right third molar)
