 Introduction: Age estimation has been an important role of forensic odontologists and they determine it by methods  like incremental analysis, Nolla’s method and Demirjian’s method. In this study, we have used the Demirjian’s method of age assessment on a Nepalese population and seen the applicability by relating it to the chronological age. Materials and methods: This study was conducted on panoramic X–rays of 285 patients including 170 males, 115 females were taken and the chronological age and the dental age as estimated by the demirjian method used on seven left mandibular teeth has been compared. Results: The difference between the dental and chronological age in the Nepalese population sample was significant statistically. (P<0.0001) Also, it was found that in the girls and boys of age 6 to 7 years, the difference was significant where as in 9.1 – 11 years age group, the difference was insignificant. Conclusion: Our study on Nepalese population has also showed a more advanced dental age. It is thought to be mainly because of the variability in ethnicity, nationality, socio– economic status and hence the nutrition of the patient.
