Aim & Objectives: To evaluate Demirjian's method's accuracy in calculating DA for the North Gujarat group of children and to Generate an appropriate age-predictive equation for the research group.
Material & Methods: In this cross-sectional retrospective study, 90 Orthopantograms (OPGs) from healthy children between the ages of 11 and 16 were selected from the medical records of Narsinhbhai Patel Dental College & Hospital (NPDCH) and evaluated to estimate dental ages.
Results: Distribution of study participants were based on age and gender, majority (31.1%) are from the age group of 16 years. Among the genders, the majority of female participants (58.3%) are from age groups 12 and 13 years, whereas the majority of male participants (64.3%) are from age groups 16 years. A formula for estimating dental age was created using logistic regression.

Conclusion: Current study showed a link between the chronological and dental ages of both sexes, with a statistically significant difference (p<0.05). Thus, it can be concluded that Demirjian’s method can be applied to this population. Though studies with a larger sample size need to be conducted for better accuracy in this particular population.
