Abstract: Aims and objective of the study was to assess age of children by using Demirijian's method and also to estimate the efficacy of Demirijian's method in South Indian Children. The present study comprised of 25 subjects 3-16 years from Mangalore, South India. Dental age was assessed by using the Demirijian's method. Panoramic radiographs were taken for the same. The obtained data were analysed by using paired t test, intra class correlation coefficient and regression analysis using SPSS 13 software for statistical analysis. Average chronological age was 10.125 ±2.3492. Average age estimated by Demirijian’s method was 10.244 ±2.3815. The intraclass correlation coefficient between the two methods showed (ICC > 0.85) excellent agreement between the two. Statistical analysis indicated that there is no significant difference between chronological age and age obtained by Demirijian’s method. Demirijian’s method has been employed by many authors mainly in the Western population. Few studies have been done in Indian population. The present study indicated that,Demirijian’s method was reliable for age estimation in our population. Age of subjects can be estimated with a good degree of accuracy using regression equation which was obtained after statistical analysis.
