摘要
目的从理想值、觉察值和容忍值3个层次探讨影响正畸患者对牙列中线轴向倾斜审美评价的因素。方法使用牙列中线不同程度轴向倾斜的图片模型，制作电子问卷软件，对222例符合条件的正畸患者分理想值、觉察值和容忍值3个层次进行问卷调查，收集其个人资料并进行口腔正畸l临床检查。结果患者对牙列中线轴向倾斜的平均觉察值是4．9°．平均容忍值是9．7°；觉察值和容忍值的中位数分别是5°和9．5°。将患者的性别、婚姻状况、受教育程度、矫治情况、错[牙合]畸形程度客观评分、牙齿美观的他人评价和自我评价这7个因素纳入Logistic回归分析，结果显示，影响牙列中线轴向倾斜觉察值的因素为受教育程度和矫治情况；影响容忍值的因素为受教育程度和性别；理想值集中于0°，并且不受上述7个因素的影响。结论正畸患者的受教育程度、矫治情况及性别是影响其牙列中线轴向倾斜审美评价的因素。
Objective To explore the related factors that might had effect on orthodontic patients＇ esthetic evaluation of axial dental midline angulation from three aspects which are ideal value, detectable value and tolerable value. Methods Photographs of a smiling woman was digitally manipulated to produce models with left or right maxillary axial dental midline angulations in 2° increments. These digital photographs models were used to develop an electronic questionnaire in combination with corresponding guidance for each question. The electronic questionnaire was applied to investigate the esthetic evaluation of axial dental midline angulation from 222 orthodontic patients who complied with the inclusion criteria. Esthetic evaluation included three aspects, the ideal value, the detectable value and the tolerable value, which represented the degrees of maxillary axial dental midline angulations the patienls considered to be ideal, detectable and tolerable, respectively. The patients＇ personal information and clinical orthodontic examination results were collected as well. Results The mean detectable value and tolerable value were 4.9° and 9.7°, the median of detectable value and tolerable value were 5°and 9.5°. Logistic regression analysis was applied to explore the influence of seven factors on each evaluator＇s ideal value, detectable value and tolerable value. The seven factors were gender, marriage condition, education level, orthodontic treatment condition, malocclusion index, dental esthetic rating from others and from themselves. The statistical analysis indicated education level and orthodontic treatment condition were the influential factors of detectable values, while the tolerable values were influenced by the education level and gender. The ideal value converged to 0° and none of the factors had effect on it. Conclusions The education level, orthodontic treatment condition and gender are considered to be the influential factors of the esthetic evaluation of axial dental midline angulation.
