摘要
目的 调查北京海淀地区大学生对不同女性微笑时前牙美学参数的认知和对前牙美学的关注程度,以便临床医师了解年轻患者对牙科美学的需求.方法 采用多张单一变量口唇部照片,调查北京海淀地区10所高校大学生对唇齿关系、牙齿形态、牙龈形态等5项美学参数的认知.采用表格评分研究受访者对上前牙牙齿形态、牙齿排列、牙龈形态等20个方面的关注程度.应用SPSS17.0软件进行卡方检验.结果 共发放500份问卷,回收有效问卷408份,47.5％(194/408)的人更喜欢“上前牙切端与下唇轻微接触”；49.5％(202/408)认为“微笑时露出8颗牙齿”更美观；69.1％(282/408)更喜欢“上中切牙为卵圆形”；52.5％ (214/408)选择上中切牙牙冠宽长比为0.85；49.5％(202/408)认为上前牙龈缘连线“与水平面平行”更美观.男性对前牙美观的关注百分比为52.6％(100/190),女性为59.6％ (130/218).结论 大部分受访者的选择与经典美学原则相符,不同性别在美学参数的认知和关注程度上存在差异.
