An evaluation of correlation between the clinical width of maxillary anterior teeth and facial measurements

Abstract

Background: This study aimed to determine the possible relationship between the width of the maxillary anterior teeth and facial measurements. Materials and method: A cross-sectional study design was used with a sample size of 92 students at the University of Medicine and Pharmacy, Hue University, meeting the sampling criteria. The measurements were measured using AutoCAD. We used Pearson coefficients to determine the possible correlation between these measurements. Results: A weak positive correlation existed between maxillary central incisor width and facial measurements (p < 0.05). The inter-canine distance was not correlated with the inner canthal distance (p > 0.05); but had a moderate positive correlation with the nasal width and the inter-commissural width (p < 0.05). Conclusion: The results suggested that inner canthal distance, nasal width, and inter-commissural width can be respectively used as a preliminary guide for determining the width of the maxillary central incisor and the inter-canine distance through the biometric ratios or the correlation equations. Key words: Maxillary central incisor width, facial measurement.
