Aim: The study was conducted to evaluate the applicability of Demirjian method and its comparison with Indian formulas for estimation of dental age in subjects attending a dental school in South India. Materials and Methods: A total of 250 individuals (130 males and 120 females) between 7 and 18 years, with orthopantamographs were included in the study. Chronological age was recorded based on subject俟Q製 date of birth. Dental age was estimated using Demirjian俟Q製 and Indian formulas. All the data obtained was entered into spreadsheet and subjected to statistical analysis. Results: The mean chronological age of the study sample was 12.39 ± 3.32 years; while the mean age obtained from Demirjian俟Q製 method and Indian-specific regression formula were 11.56 ± 3.17 years and 14.20 ± 3.24 years, respectively. In the present study, the Demirjian俟Q製 method under estimated dental age by 0.84 years in males and 0.83 years in females (P < 0.05). Indian-specific regression formulas overestimated dental age by 1.72 years in males and 1.91 years in females (P < 0.05). Conclusion: The published Demirjian俟Q製 and Indian-specific regression formulas are not applicable to the present study group. Hence population-specific cubic regression formulas were developed for males and females in Bhimavaram town (South India).
