摘要
目的研究正畸治疗中骨性Ⅱ类面型患者的性别对软组织侧貌评价的影响。方法选取南京医科大学附属口腔医院2016—2020年所收治的正畸骨性Ⅱ类面型患者30例,男性15例,女性15例,年龄18~36岁。收集每位患者矫治前自然头位的剪影照片并拍摄CBCT。应用Photoshop软件对30张照片进行修改,隐藏暴露性别特征的头发、睫毛、喉结等特征,获得去除性别特征的剪影照片;将CBCT合成的头颅侧位片与自然头位剪影照片重叠获得自然头位的头颅侧位片。将30张去除性别特征的剪影照片和30张未去除性别特征的剪影照片(标明性别)随机打乱,分别制作成幻灯片,间隔5 s自动播放。邀请非专业人员对两组幻灯片分别进行打分。收集整理数据将去除性别特征组分为高分组与低分组,使用Holdaway分析法定点测量各项指标,独立样本t检验比较各指标间差异。结果去除性别特征组整体平均分、男性组平均分、女性组平均分均较未去除性别特征组低,差异有统计学意义(P<0.05)。去除性别特征组中,男性所得评分明显高于女性(P<0.05)。高、低分组与评分相关的测量指标为A点凸度、上唇基部厚度、颏唇沟深度和颏部厚度(P<0.05)。结论骨性Ⅱ类面型患者的性别对软组织侧貌的评价存在影响,男性去掉性别特征的侧貌轮廓较女性更易被普通人群接受。影响侧貌评价的美学指标为A点凸度、上唇基部厚度、颏唇沟深度、颏部厚度。
Objective To assess the influence of patients’gender on the evaluation of soft tissue profile in patients with skeletal ClassⅡmalocclusion.Methods Thirty patients with skeletal ClassⅡmalocclusion in the Affiliated Stomatological Hospital of Nanjing Medical University between 2016 and 2020 were selected:15 males and 15 females in the age range of 18—36 years.The natural head position silhouette photos of each patient were collected before treatment and CBCT was taken.Photoshop software was used to modify 30 photos to hide the hair,eyelashes,laryngeal nodes and other features that revealed gender characteristics.The same software was used to overlap CBCT synthetic lateral cephalograms with natural head position silhouettes to obtain lateral cephalograms with natural head positions.Thirty silhouette photos without gender features and 30 silhouette photos with gender features(indicating gender)were randomly scrambled and made into slides,which were automatically played every 5 seconds.Laypeople were invited to rate the two groups of slides respectively.The data were collected and sorted out,and the group without gender characteristics was divided into high score group and low score group.The Holdaway analytical method was used to measure the indicators,and independent sample t test was used to compare the differences among the indicators.Results The overall average score of the group without gender characteristics was lower than that of the group with gender characteristics obviously(P<0.05).The average score of male patients without gender characteristics was lower than that of males with gender characteristics(P<0.05).The average score of women without gender characteristics was lower than that of women with gender characteristics significantly(P<0.05).In the group without gender characteristics,the score of male patients was higher than that of female patients(P<0.05).Related measurement indicators of high score group and low score group were A-point convexity,upper lip base thickness,mentolabial groove depth and chin thickness(P<0.05).Conclusion The gender of patients with skeletal ClassⅡmalocclusion has an impact on the evaluation of soft tissue profile.Profiles of male patients without gender characteristics are popular among laypeople than the females.Aesthetic indicators affecting the evaluation of facial profile are A-point convexity,upper lip base thickness,mentolabial groove depth and chin thickness.
