Aim: The aim is to evaluate the maxillary anterior tooth proportion relationship using different calculations. Materials and Methods: Forty pleasing smile photographs were evaluated for the different calculations. Mesiodistal width of all the maxillary anterior teeth were measured and were subjected to different calculations like individual tooth width divided by the combined width of all the anterior teeth of one side and individual tooth width divided by the combined width of the remaining two teeth of one side. Calculated results were tabulated and were subjected to descriptive statistics. Results: Among the various formulas, the mesiodistal width of canine divided by the sum of mesiodistal width of central, lateral incisors, and canine showed the consistent quotient of 0.3 for all the subjects. Mesiodistal width individual teeth like central incisors when divided by the combined width of central incisor, lateral incisor and canine, also showed the constant quotient of 0.3 for all the patients. The sum of Mesiodistal width of central and lateral incisor when divided by combined width of central, lateral incisor and canine gave the constant value of 0.6. Conclusion: The consistent quotients obtained by the formulas like width of central incisors and the canine divided by the combined width of central-lateral incisors-canine and the other formulas can be used for building up of the missing teeth and the smile designing.
