New methods of dental age (DA) estimation are emerging and it is important that we compare different methods to determine which one is more closely related to the chronological age. Demirjian\u2019s method is one of the most widely used techniques and has been tested in various ethnic populations globally. In 2016, another approach to DA estimation is the London atlas of human tooth development and eruption. No study has compared Demirjian\u2019s comprehensive chart and London atlas method in the Indian population. Hence, in the current study, we estimated DA using Demirjian\u2019s comprehensive chart and London atlas method for association with the known chronologic age in children and adolescent population. The study also attempted to determine if sexual dimorphism existed in DA estimated by the two methods. Estimation was performed for both methods on 100 orthopantomogram records (50 males and 50 females, aged 6\u201316\u00a0years) of orthodontic patients. The data were compared and analysed using paired t-tests. There was an overestimation of DA by Demirjian\u2019s comprehensive chart on an average of +1.3 years in males and +0.5 years in females, whereas using London atlas, it was +1.4\u00a0years in males and +0.5\u00a0years in females. The mean of underestimation was \u22120.6\u00a0years in males and \u22120.8\u00a0years in females using Demirjian\u2019s comprehensive chart, whereas it was \u22120.8\u00a0years in males and \u22120.5\u00a0years in females. A statistically significant difference (P\u2009&amp;lt;\u20090.0001) was found when mean chronological age (11.6\u2009\u00b1\u20092.6) years of the participants was compared with DA estimated using either Demirjian\u2019s comprehensive chart (12.3\u2009\u00b1\u20092.8) years or London atlas (11.8\u2009\u00b1\u20092.9) years. The trends in this pilot study point towards more accuracy of London atlas over Demirjian\u2019s method when done using comprehensive chart for estimating DA. In summary, the results of the current pilot study indicates greater accuracy of London atlas method over Demirjian\u2019s comprehensive chart method for estimating DA in Indian population. This finding should be validated by conducting similar studies using larger sample, on diverse Indian ethnic populations, for applicability in pedodontic, orthodontic, and forensic domains.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key points<\/jats:title>\n
