Abstract

Background: The prevalence of maxillary lateral incisor agenesis ranges from 1% to 3%, with slight global variability. The unilateral agenesis of the maxillary lateral incisor is often associated with a contralateral tooth with microdontia or a peg shape and can have esthetic, functional, and psychosocial implications for patients. The aim of the present survey was to assess the perceptions of smile aesthetics among orthodontists, general dentists and laypeople on different treatment choices, modifying the initial condition of the right maxillary lateral incisor agenesis and the contralateral peg-shaped tooth.

Methods: A series of 6 photographs of different smile simulations were presented to 109 orthodontic specialists, 109 general dentists and 141 laypeople through an online survey. Each photograph was duplicated and judged from 1 to 10 for 2 different bipolar adjectives.

Results: Statistically significant results were found for all the groups investigated. All three groups preferred the photo that maintained the typical symmetrical 'high-low-high gingival contour. Moreover, both orthodontic specialists and general dentists preferred unilateral mesialization of the canine and conservative rehabilitation of the peg-shaped incisor. In contrast, the laypeople preferred bilateral mesialization of the canines with peg-shaped incisor avulsion.

Conclusion: The normal symmetrical array of the central incisor, lateral incisor and canine had the best aesthetic results for all subjects. Laypeople were more attracted to a symmetrical smile than were the groups of orthodontic specialists and general dentists.

正畸专家、普通牙医和外行人对缺上侧门牙和缺上侧门牙的不同微笑表现的审美感受。
背景:上颌侧切牙发育不全的患病率范围为1%至3%,具有轻微的全球变异性。上颌侧切牙单侧发育不全通常与对侧牙齿小齿或牙钉形状相关,并可能对患者产生美学、功能和社会心理影响。本研究的目的是评估正畸医师、普通牙医和非专业人士在不同治疗选择下对微笑美学的认知,改变右上颌侧切牙发育不全和对侧桩形牙的初始状态。方法:对109名正畸专科医生、109名普通牙医和141名非专业人员进行在线调查,收集6组不同模拟笑容的照片。每张照片都被复制,并根据两个不同的双相形容词从1到10进行评判。结果:两组间差异均有统计学意义。三组人都更喜欢保持典型的对称“高-低-高”牙龈轮廓的照片。此外,正畸专家和普通牙医都倾向于单侧犬齿化和门牙钉形的保守修复。相比之下,外行人更倾向于双侧门牙撕脱。结论:中切牙、侧切牙和犬齿的正常对称排列具有最佳的审美效果。普通人比正畸专家和普通牙医更容易被对称的微笑所吸引。
