Abstract
Background: This study aimed to assess the accuracy of chronological age estimation based on dental measurements made on the Periapical (PA) radiographs of an Iranian adult population.
 
 Methods: This study evaluated 90 parallel PA radiographs of sound maxillary canine teeth of 39 males and 51 females. Tooth length, root length, pulp length, pulp width, and root width at points A, B, and C according to Kvaal’s method were measured on PA radiographs using Scanora software. The collected data were analyzed using SPSS.
 Results: Maximum root width at point A provided the highest accuracy for gender estimation (77.7%). A significant correlation was noted between maximum pulp width at points B and C with age. Besides, a regression formula for age estimation was obtained.
 Conclusion: Maximum pulp width at points B and C could be used for age estimation in the adult population besides other parameters.
