Aesthetic appraisal is rarely included in the objective assessment of outcome studies of impacted maxillary canines treatment. The present study aimed to validate a new index for assessing the aesthetic appearance of maxillary canines and adjacent soft tissues. The Department of Oral and Maxillofacial Surgery at University Hospitals Leuven. Four oral-maxillofacial surgeons, two orthodontists, two prosthodontists, and two lay persons rated 11 maxillary canines and adjacent soft tissues according to the new index. Each of the examiners repeated the examination three times with a 2-week interval. Twelve relevant aesthetic variables were selected on the basis of the anatomic form, color, and surface characteristics of the canine crown and on the basis of the anatomic form, color, and surface characteristics of the adjacent soft tissues. Intraclass correlation (ICC) coefficient and Fleiss' kappa statistics were performed to analyze the intrarater and interrater agreement. The index proofed to be a reliable assessment tool. Considering the cumulative assessment of the Maxillary Canine Aesthetic Index (MCAI), the mean ICC value for the interrater agreement of the 10 examiners was 0.71, representing a good agreement. Intrarater agreement ranged from 0.10 to 0.91. Interrater agreement (Fleiss' kappa statistics) calculated for each variable ranged from 0.08 to 0.98. The MCAI is a tool in rating aesthetic outcome of impacted canine treatment and adjacent soft tissues. The MCAI can be used to evaluate the aesthetic outcome after surgical exposure or transalveolar transplantation of maxillary canines.
美学评估很少被纳入上颌阻生尖牙治疗效果研究的客观评估中。本研究旨在验证一种用于评估上颌尖牙及相邻软组织美学外观的新指标。鲁汶大学医院口腔颌面外科。四名口腔颌面外科医生、两名正畸医生、两名修复医生和两名外行人根据新指标对上颌11颗尖牙及相邻软组织进行评分。每位检查者每隔2周重复检查三次。根据尖牙冠的解剖形态、颜色和表面特征以及相邻软组织的解剖形态、颜色和表面特征，选择了12个相关美学变量。采用组内相关系数（ICC）和Fleiss' kappa统计量分析检查者内和检查者间的一致性。该指标被证明是一种可靠的评估工具。考虑到上颌尖牙美学指数（MCAI）的累积评估，10名检查者间一致性的平均ICC值为0.71，表明一致性良好。检查者内一致性范围为0.10至0.91。每个变量计算的检查者间一致性（Fleiss' kappa统计量）范围为0.08至0.98。MCAI是一种对上颌阻生尖牙治疗及相邻软组织美学效果进行评分的工具。MCAI可用于评估上颌尖牙手术暴露或经牙槽移植后的美学效果。
