Factors Influencing Facial Profile Evaluation / 中国医科大学学报

ABSTRACT

Objective To characterize differences within facial profile esthetic evaluations among three groups of evaluators and the influences of sagittal or vertical skeletal patterns on facial profile esthetics. Methods A total of 114 silhouettes,from the pre?or post?treatment facial profiles of 57 patients,were scored by three groups of evaluators(professionals,patients'parents,and laypersons)to characterize differences within facial es?thetics evaluation among evaluators. The highest?scoring 30 silhouettes and the lowest?scoring 30 silhouettes were selected as the high score group and the low score group,respectively. Sixteen indices of the relative lateral cephalometric films were measured. Data were analyzed by SPSS 21.0. Results Facial profiles following orthodontic treatment scored higher than pre?treatment(P<0.05). There were significant differences between professionals and laypersons in facial profile scoring. Different sagittal skeletal patterns had no effect on esthetic evaluation ,but lower facial height significantly influenced whether a patient received a high or low esthetic score(P<0.05). Conclusion Orthodontic treatment can improve the fa?cial profile significantly,and lower facial height is the most sensitive index for facial profile evaluation in our study. However,all three evaluator groups have different esthetic standards that don't overlap. Notably,the expectations of laymen are higher than those of orthodontists.
