Abstract :Aim: The age estimation method introduced by Nolla in 1960 comes under age determination during the first two decades of life. Present study is conducted to assess age of children by using Nolla\'s method and also to estimate the efficacy of Nolla\'s method of age assessment in Mangalorean Population. Materials and method: The present study was conducted on 25 selected subjects (15 males and 10 females) ranging from 3-16 years from Mangalore. Dental age assessment was done using Panoramic radiographs 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. Results: Average chronological age was 10.213 ±2.3385. Average age estimated by Nolla’s method was 10.040 ±2.2485. The intraclass correlation coefficient between the two methods showed excellent agreement between the two. Statistical analysis showed that there is no significant difference between chronological age and age obtained by Nolla’s method.. Conclusion: Nolla’s method of age estimation was accurate in both males and females. Age of subjects can be estimated with greater degree of accuracy using regression equation which was obtained after statistical analysis.Keywords : Panoramic radiograph, Regression equation, Nolla’s method, age estimation.
