Materials and Methods: One hundred healthy individuals undergoing PR for various dental procedures were included in this study after obtaining consent. Pulp/tooth ratio using Cameriere et al. method on mandibular canine and linear measurements related to mental foramen, i.e., the distance between the superior and inferior border of the mandible (S-I) and the mandible’s superior border to the superior margin of the mental foramen (S-sM) were estimated using Adobe Photoshop image editing software. Later, buccal smears obtained from the same individual were fixed with 95% alcohol and stained with Papanicolaou’s stain for cytomorphometric analysis. The age was calculated using the regression analysis and correlated with chronological age. Results: Statistical significance and better correlation were obtained pulp/ tooth area ratio, the distance of S-I of all age groups. However, the distance of S-sM proved to be more effective in Group 4 (51-60 years) and buccal cell size was found to be comparable to the chronological age particularly in Group 5 (above 60 years). Conclusion: In the present study, the accuracy of estimated age compared to the chronological age was more promising for pulp/tooth area ratio, followed by S-I, S-sM, and cell size.展开更多
