Quantifying the Selection of Maxillary Anterior Teeth Using Extraoral Anatomical Landmarks.

Abstract

Background: Regardless of skin color, age, sex, or other factors, all beautiful faces follow the divine proportion. Proportions of face components appear to play a role in facial attractiveness.Aim: The study determines the correlation between the mesiodistal width of anterior maxillary teeth, inter-canthal distance, inter-alar distance, and inter-commissural distance as a criterion for selecting anterior maxillary teeth.Material and Methods: A cross-sectional study was carried out at the institutional level with a sample size of 200 participants with 100 male and 100 female participants. Inter-canthal distance, inter-alar distance, and inter-commissural distance were measured using the digital caliper and a customized silver scale to measure the mesiodistal width of anterior maxillary teeth. The data obtained were analyzed using Statistical Package for Social Sciences (SPSS) version 24.0 (IBM Corporation, Chicago, USA). Pearson's correlation test calculated the correlation coefficient, and the level of significance was kept at p<0.05.Result: The width of the maxillary anterior and the inter-canthal gap showed a strong positive correlation, the inter-alar difference and the mesiodistal width of anterior teeth showed a moderately positive correlation, and the estimated inter-commissural width and the mesiodistal width of anterior teeth showed a strong positive correlation (p<0.05).Conclusion: These parameters are correlated to the dimensions of the tooth size and can act as a guide while selecting the teeth for future rehabilitation treatment when the natural teeth are lost.
