Abstract：
OBJECTIVE: To investigate the impact of various degrees of white spot lesions (WSLs) of maxillary anterior teeth on the aesthetic perception and treatment satisfaction among orthodontic patients, orthodontists and other dental specialists and to evaluate the differences among the three groups.
METHODS: A total of 45 orthodontic patients (OP), 45 orthodontists (OR) and 45 other dental specialists (OS) were recruited. Subjective evaluations of perceived aesthetics and treatment satisfaction were performed towards eight digitally generated photographs of maxillary anterior teeth with incremental degrees of WSLs using a numerical visual analogue scale (VAS) from 0 to 100. Data were collected and analysed with descriptive statistics, repeated one-way analysis of variance and multivariable generalized estimating equations.
RESULTS: A total of 135 valid questionnaires were collected. Regarding aesthetic scores for WSLs, OP gave more positive scores than OR and OS (p < .05) towards excessive white spot formation without colouration and were more tolerant than OR (p < .05) towards excessive white spot formation with slight colouration. The level of treatment satisfaction for slight to severe WSLs without cavitation was higher in OP than OR. Patients with higher education levels had more negative scores for aesthetic perception and treatment satisfaction (p < .05). Patients who brushed teeth more frequently scored lower in treatment satisfaction (p < .05).
CONCLUSIONS: Orthodontists were the most critical when evaluating aesthetics and treatment satisfaction for slight to severe WSLs without cavitation. For orthodontic patients, better oral hygiene habits and higher education levels were associated with more critical attitudes towards WSLs.

摘要：
目的：探讨上颌前牙不同程度的白斑病变（WSLs）对正畸患者的审美知觉和治疗满意度的影响。正畸医生和其他牙科专家，并评估三组之间的差异。
方法：共45例正畸患者，招募了45名正畸医生（OR）和45名其他牙科专家（OS）。使用数字视觉模拟量表（VAS）从0到100，对八张数字生成的WSL递增的上颌前牙照片进行了感知美学和治疗满意度的主观评估。收集数据并进行描述性统计分析，方差和多变量广义估计方程的重复单向分析。
结果：共收集有效问卷135份。关于WSL的美学分数，对于无着色的过度白斑形成,OP比OR和OS(p<.05)给出更多的正分数,并且对于有轻微着色的过度白斑形成比OR(p<.05)更耐受。对于无空化的轻度至重度WSL，OP的治疗满意度高于OR。受教育程度较高的患者在审美感知和治疗满意度方面的负面得分较多（p<0.05）。刷牙频率较高的患者在治疗满意度方面得分较低（p<0.05）。
结论：正畸医生在评估轻度至重度无空化的WSL的美学和治疗满意度时最为关键。对于正畸患者，更好的口腔卫生习惯和更高的教育水平与对WSL的更多批判性态度相关。
