Purpose: The position and size of the anterior teeth have direct influence on clinical appearance of the smile. The anterior teeth rarely follow all the mathematic rules of a proportionate smile. To determine maxillary anterior teeth proportions in Indian Population, their correlation with existing mathematical parameters and their reliability should be evaluated. Materials and Methods: A total of 350 participants were evaluated for healthy maxillary anterior teeth. Based on the inclusion/exclusion criteria, 230 were included in the study. Five photographs of the anterior maxillary area with three different angles were performed under standardized conditions. Images were analyzed and the data were collected. Results: The observed values of width and height were closely related to Proportion Gauge. Width proportions between two adjacent teeth and the observed tooth proportions are in concordance with the values given by Digital Smile Design (DSD®). Variables defined were analyzed in Minitab software using descriptive statistics and inferential tests (t-test with 95% confidence interval). Conclusions: The Proportion Gauge and DSD® Protocol can be used for rehabilitation of maxillary anterior teeth in the studied population.
