Background: The aim of the study was to correlate the radiologic development status of third molars withthat of chronologic age specifically among individuals belonging to Dakshina Kannada and Udupi districtin the age group of 16-22 years.Method: A total of 152 orthopantomograms (OPG) were evaluated to assess the development status andscored using the evaluation method suggested my Gleiser and Hunt. Intra- and Inter-observer reliabilitywas evaluated using the k statistics. Statistical test used were multiple regression analysis and Pearsoncorrelation coefficients.Results and Conclusion: The formula to determine chronological age among females is Age= 13.416 +(-0.873 Upper Right (UR)) + 0.803 Upper left (UL) + 0.536 Lower left ( LL) + 0.362 Lower Right (LR)with standard deviation of 1.61, and for males is Age = 12.766 (-0.187 UR) + 0.748 UL + 0.873 LL + (-0.541LR) with SD of 1.57.
