The age of the individual can be assessed ac skeletal age, morphological age, secondary sex character age and dental age and these maybe applied singly or in conjunction to assess the degree of physical maturity of a child. The determination of physiological age is based on the various degree of maturation of the different tissue systems. Dental age is one of the important factor taken into account when formulating treatment plans and having particular relevance to the timing of treatment. Aim: The study was designed to determine dental age from orthopantomograph using Demirjian method and to investigate applicability of Demirjian method for estimation of chronological age in Central Indian (Indore, Madhya Pradesh) population. Materials and methods: The sample for the study consisted of 210 individuals between 72-156 months (6-13 years) of age randomly selected from various schools. Panoramic radiographs of all individuals were studied and dental age was calculated by using Demirjian's method. Results and conclusion: When Demirjian method was applied to Indore children mean difference between true and assessed age for males showed overestimation of 1.34 months, i e. overestimation by 40 days and females showed overestimation of 1.97 months, i.e overestimation by 59 days. The mean difference between true age and assessed age for total sample was 1-66 months, i.e overestimation by 49 days. Positive correlation showed in total male and female sample along with male and female combined sample. Age estimation using Demirjiani's method was found to be accurate when applied to Central Indian (Indore, Madhya Pradesh) population.
