:  Teeth development is widely used for age estimation in forensic science. The aims of this study were as follows: first, to establish Indian data on canine and first premolar development for age estimation and second, to investigate population differences in teeth development. Orthopantomograms of 340 Indian children aged between 5 and 14 years were analyzed. Demirjian’s stages were recorded for the developmental evaluation of canine and first premolar and for further descriptive statistical analysis. A two‐way ANOVA was performed to test the significance of difference in teeth development by sex and stage. A one‐way ANOVA was performed to investigate population differences in teeth development. Results showed statistically significant differences in teeth development by sex and stage. Accordingly, teeth development was earlier in girls. No statistically significant differences were observed in timings of Demirjian’s stages among different populations. In conclusion, the findings of this study could be used for age estimation of Indian children.
