【摘要】 目的　了解不同牙颌畸形与青少年自尊发展的关系。方法　通过错畸形流行病学调查 ,筛选出 344例受试者。其中健康对照组 78人 ,安氏Ⅰ类、Ⅱ类、Ⅲ类错者分别为 91例、93例、82例。各牙颌畸形组又分为轻度、中度、重度 ,年龄在 12～ 18岁。调查对象为大连市中小学生。采用儿童自尊量表 (childrenself esteemscale ,CSES) ,对所得数据进行统计学处理。首先将两个量表的各分量表进行单因素分析 ,然后对有意义的变量应用多元线性逐步回归及二分类logistic多元回归模型 ,进行控制和筛选。进一步发现影响青少年低自尊的危险因素。结果　牙颌畸形对于青少年自尊有影响 :①畸形类型与自尊总值、外表分量表测值有显著相关性 ,单因素及多因素分析结果显示 ,安氏Ⅰ类、Ⅱ类、Ⅲ类错患者的分值明显低于正常对照组 ,其中Ⅱ类错患者分值最低。重度畸形是外表意象低的危险因素。②牙颌畸形程度与自尊总值、外表分量表和成就感分量表测值呈负相关。牙颌畸形越重 ,自尊值越低。③男性患者的外表自信高于女性。结论　①青少年时期 (12～ 18岁 )牙颌畸形主要影响其外表自尊值。其中安氏Ⅱ类错者外表自尊值低于安氏Ⅰ类和Ⅲ类。②重度牙颌畸形对于青少年的外表自尊影响大 ,中度、重度畸形者自尊值低于轻度和对照?更多还原
