汉族最具吸引力微笑人群的上颌前牙尺寸与面部尺寸的相关性分析
Analysis of the associations between maxillary anterior teeth and facial measurements in Han Chinese individuals with the most attractive smiles
摘要
Abstract
Objective This study aimed to analyze the correlations and proportional relationships between maxillary anterior teeth(MAT)and facial measurements in Han Chinese individuals with the most attractive smiles,as evaluated by dental professionals.Methods Ten dentists with more than 5 years of clinical experience from different professional directions in a tertiary stomatological hospital were selected to evaluate the smile attractiveness of volunteers by visual analogue scale(VAS).Eighty-eight Han volunteers with the most attractive smile were selected.The perceived width of the MAT,the dimensions(height and width)of the maxillary central incisors(MCI),and the facial dimensions(intercanthal distance,interzygomatic distance,interalar dis-tance,facial height and lower facial height)of the volunteers were measured on the frontal photos of the smile,digital oral model,and 3D face model.Pearson correlation analysis was performed to analyze linear correlations,and regression analysis was carried out to explore the proportional relationships.Reliability analysis using the intraclass correlation coef-ficient verified the stability of these proportional relationships.In addition,the correlations between MAT perceived width and the proportional relationships of(MCI)height to width ratio,with facial dimensions were explored and their reliability was verified.Results In Han Chinese individuals with the most attractive smiles,as evaluated by dental pro-fessionals,the Pearson correlation coefficients among MAT perceived widths were 0.813,0.389,and 0.560.A proportion-al relationship existed between the lateral incisor and central incisor,and the ratio was 0.729.No significant correlations were found between MCI and the inner canthal distance,zygomatic distance,interalar distance,facial height,or the low-er one-third facial height except for a negative correlation(r=-0.357)between MCI height and facial height in males and a positive correlation(r=0.249)between MCI width and interalar width when genders were combined.Conclusion Correlations exist among MAT perceived widths in Han Chinese individuals with the most attractive smiles,as evaluated by dental professionals.Partial correlations are observed between MCI height and width and facial measurements.The perceived width of the lateral incisor can serve as a reference indicator for predicting the perceived width of the central incisor,providing a reference for the aesthetic restoration of MAT in the Han ethnicity population.关键词
