影响牙列中线偏移审美认知的相关因素分析

Influential factors of the aesthetic perception to dental midline deviation

目的从审美理想值、察觉值及容忍度3个维度上探讨可能影响人群牙列中线偏移审美认知的相关因素。方法设计牙列中线偏移审美认知电子问卷,对符合纳入标准的正畸求诊患者进行电子问卷调查,配合相应口腔临床检查。应用Logistic回归分析研究牙列中线偏移审美认知的影响因素。结果牙列中线偏移审美理想值在0mm左右呈集中趋势,且不受受试者个人因素的影响。Logistic回归分析显示,影响牙列中线偏移察觉值的因素包括文化程度、矫治情况及错程度客观评价;影响牙列中线偏移容忍度的因素包括文化程度和错程度客观评价。结论牙列中线与面中线一致是大众审美追求的目标。调查群体的文化程度、矫治情况及错程度会影响其牙列中线偏移的审美认知。

Objective To evaluate the potential factors that might affect orthodontic patients＇ aesthetic perception to dental midline deviation from the following three aspects：the ideal value,the detectable value,and the tolerable value.Methods An electronic questionnaire was designed to investigate the orthodontic patients who met the inclusion criteria.The patients were asked to select the ideal value,the detectable value,and the tolerable value of a series of pictures with dental midline deviation in the questionnaire followed by an oral examination.The Logistic multivariate regression analysis was used for related factors analysis.Results The ideal value of dental midline deviation distributed around 0 mm.Personal information of the patients had no effect on the selection of the ideal value.The education level,orthodontic treatment,and the malocclusion degree were the influential factors of the detectable value.As for the tolerable value,the influential factors contained the education level and the malocclusion degree.Conclusions People prefer dentofacial midline consistency.The education level,orthodontic treatment,and the malocclusion degree of the subjects were considered to be the influential factors of the aesthetic perception to dental midline deviation.
