摘要： 目的:研究不同人群对中切牙龈缘高度不对称的敏感性与可接受度,探讨不同人群对软组织美学的看法,使临床医生更好的完成前牙美学修复。方法:本实验为随机对照试验,共调查受试者913名并分为3组,将不同程度的双侧中切牙龈缘高度不一致的图片打乱顺序让受试者进行VAS评分及接受与否调查了解其敏感度和接受度,结果使用SAS 9.3软件进行统计分析。结果:口腔专业人士的最小察觉值为龈缘位置变化±0.75 mm(P<0.05),有修复史和无修复史的非专业人员均为+1.00 mm和-1.50 mm(P<0.05)。口腔专业人员50%接受度值为±1.00 mm,非专业人员为+1.50 mm和-1.25 mm。结论:口腔专业人员比非专业人员更容易察觉牙龈的变化,同时可接受的范围也较小。

Abstract: Objective: To study the sensitivity and acceptability of different groups for the asymmetry of central incisors gingival margin, to explore the views of different people on the aesthetics of soft tissue, and to guide the clinicians for better repair of anterior teeth. Methods: This experiment is randomized and controlled trial. Participants (913) were divided into A, B, C three groups. Gingival margin pictures with different degrees of asymmetry were disordered and subjected for VAS score and acceptance by three groups, which was used to learn the sensitivity and acceptance. Results: The minimal detection rates of dental professionals were ±0.75mm (P<0.05), and those of laypersons were +1.00mm and -1.50mm (P<0.05). Dental professionals’ 50% acceptance values were ±1.00mm and those of laypersons were +1.50mm and -1.25mm. Conclusion: Professionals are easier to detect gingival changes than laypersons, and they have small range of acceptance.
