Introduction: Smile is an important part of facial esthetics. Various authors have established a mathematical correlation between maxillary and mandibular teeth dimensions and dwelled upon its importance in smile designing. The present study aims to validate one such mathematical relation in the Indian population with an objective to identify the tooth exhibiting maximum variation. Materials and Methods: The present study was conducted by using 225 study models. Mesiodistal dimensions of the maxillary and mandibular anterior teeth were recorded and applied to the mathematical relation for assessing the validation. Results: 37.8% of the study models showed complete validation of mathematical relation. Females showed significantly higher validation compared to males (P < 0.01). However, validation did not differ significantly in relation to malocclusion. 15.6% of the study models of the patients exhibited mandibular canine with increased mesiodistal dimension, 13.3% of the study models showed maxillary central incisor, while 8.9% of the study models sample showed maxillary lateral incisor with decreased mesiodistal dimension, responsible for invalidation. Conclusions: Mathematical relation under validation was found to be completely validated in 37.8% of the study sample of the Indian population. Validation was observed to be more in females than in males. Mandibular canine followed by maxillary central incisor was most commonly involved for the invalidation of mathematical relation.
