摘要
目的:探讨下颌第一磨牙龋损状况和颞下颌关节紊乱病(TMD)的关系和作用机制,为预防因下颌第一磨牙龋损而导致的TMD提供流行病学依据。方法:以西安市驻军某部入伍新兵为研究对象,采用下颌第一磨牙龋损、TMD临床诊断标准和安氏分类等方法,对896名17—20岁入伍新兵进行流行病学研究,分析下颌第一磨牙龋损状况和TMD发病之间的关系。结果:受测人群中下颌第一磨牙龋患率为55.3%。正常袷TMD阳性率为8.6%,异常耠TMD阳性率为37.1%,二者有显著性差异(P〈0.05);龋损组正常袷和异常袷受测者TMD阳性率明显增高(龋损组TMD阳性率分别为10.6%和49.5%,P〈0.05),正常袷和异常袷中下颌第一磨牙龋损波及功能面的受测者TMD阳性率远远高于未波及功能面受测者。结论:下颌第一磨牙龋损是引起异常袷和TMD的重要原因之一,龋损波及功能面者更易导致TMD。
Objective:To study the pathogenic relationship and the mechanisms between dental caries of mandibular first molar and the temporomandibular disorders (TMD) for providing proportional epidemiology data. Methods:The local recruits as investigation object were selected and an epidemiological study was carried out in the population of 896 soldiers with standard clinical diagnostic criteria for dental caries, TMD and Angles classification. Results:The dental caries rate in mandibular first molar was 55.3%. TMD positive rates in normal and abnormal occlusion were 8, 6% and 37.1% respectively which showed significant difference. Compared with the non-caries group, TMD positive rate in the normal or abnormal occlusion groups with dental caries of mandibular first molar involved functional surface were far higher. Conclusion :Dental caries of the mandibular first molar was one of important causes of abnormal occlusion and TMD and the caries involved functional surface of teeth were more susceptible to TMD.
