The aim of this study was to determine which dental esthetic self-perception evaluation tool discriminated better between orthodontically treated or untreated Peruvian young adults. A total of 630 students were randomly chosen from the 2000 admitted in 2002 to a private university in Peru. Students undergoing active orthodontic treatment at the time of examination were excluded. Self-perceived dental esthetic appearance was evaluated through Standardized Continuum of Aesthetic Need, Oral Aesthetic Subjective Index Scale, and Visual Analogue Scale (VAS). A stepwise multivariate discriminant analysis was developed to classify orthodontic treatment according to the three evaluation tools. A total of 199 students (31.6%) reported a history of orthodontic treatment. Differences between orthodontically treated and untreated groups were found only for the mean VAS score (P < .001). Although three different approaches were used to evaluate dental esthetic self-perception, only VAS allowed the discrimination of the self-perceived dental appearance between orthodontically treated and untreated Peruvian university young adults. Similarities in the self-perceived dental appearance of treated and untreated groups reported in previous epidemiological studies could be explained because different evaluation instruments were used. Further studies are required to support current findings.
本研究的目的是确定哪种牙齿美学自我认知评估工具能更好地区分接受正畸治疗或未接受正畸治疗的秘鲁年轻成年人。从2002年被一所秘鲁私立大学录取的2000名学生中随机选取了630名学生。排除在检查时正在接受积极正畸治疗的学生。通过美学需求标准化连续体、口腔美学主观指数量表和视觉模拟量表（VAS）对自我感知的牙齿美学外观进行评估。根据这三种评估工具，开展了逐步多变量判别分析以对正畸治疗进行分类。共有199名学生（31.6%）报告有正畸治疗史。正畸治疗组和未治疗组之间的差异仅体现在VAS平均得分上（P <.001）。尽管使用了三种不同的方法来评估牙齿美学自我认知，但只有VAS能够区分接受正畸治疗和未接受正畸治疗的秘鲁大学生的自我感知牙齿外观。先前流行病学研究中报告的治疗组和未治疗组在自我感知牙齿外观上的相似性，可能是因为使用了不同的评估工具。需要进一步的研究来支持当前的研究结果。
