目的探讨乳牙列夜磨牙症影响因素。方法选取2007年1月至2010年11月在云南省人民医院口腔预防保健科门诊就诊的32例乳牙列夜磨牙症患儿为病例组,随机抽取与病例组同期、同地点就诊的32例除外夜磨牙症的其他乳牙列口腔疾病患儿为对照组,并且病例组与对照组患儿在年龄、性别上相匹配。对研究对象进行口腔检查,对其父母进行问卷调查,并以Achenbach儿童行为量表进行心理行为检测。采用SPSSl0.0统计软件分析各项因素与夜磨牙症的相关关系。结果两组儿童在父母磨牙、龋患情况、牙本质磨耗、心理行为量表总分方面差异有统计学意义(P<0.05);在咬合关系、特定的睡眠姿势等方面差异无统计学意义。结论儿童夜磨牙症的发生与精神心理因素、遗传因素可能有相关关系;与咬合关系、特定的睡眠姿势等可能无关。
