正畸治疗与颞下颌关节症状的相关研究

The relationship between orthodontic treatment and temporomandibular disorders

目的:探讨正畸治疗和颞下颌关节紊乱病(TMD)的关系。方法:设计正畸组、错组和正常组的调查表,用Visual Foxpro6.0建立相应的数据库,对173例已正畸治疗者、95例有错畸形但未治疗者和32例正常对照进行TMD症状、体征及相关情况的问卷调查和专科检查,所得结果用基于Helkimo指数改良设计的数据库进行分析,采用SPSS10.0软件包进行成组设计两样本比较的秩和检验。结果:正畸组和错组在主诉症状指数、临床症状指数和咬合指数的分布上存在显著差异(P<0.001);正畸组和正常组在主诉症状指数和临床症状指数的分布上有显著差异(P<0.001),但在咬合指数的分布上无显著性差异(P>0.05)。结论:正畸治疗后患者在一定时期内易出现颞下颌关节紊乱病的症状和体征。

PURPOSE： To explore the relationship between orthodontic treatment and temporomandibular joint disorder（TMD）. METHODS： The questionnaire and clinical examination were administered in 173 cases who underwent orthodontic treatment （orthodontic group）,95 cases with morphologic malocclusion（ malocclusion group） and 32 cases with normal occlusion （normal group） to collect symptoms and signs of TMD, the data were analyzed in the databases designed according to the modified Helkimo indices. SPSS10.0 software package was used for Wilcoxon test. RESULTS： There were statistically significant differences between the orthodontic group and malocclusion group in the distribution of anamnestic, clinical dysfunction and occlusion indices （P〈0.001）. There were statistically significant differences between the orthodontic group and normal group with regard to the distribution of anamnestic, clinical dysfunction indices （P〈 0.001 ）. No statistically significant differences were found between the orthodontic group and normal group in terms of occlusion indices （P〉0.05）. CONCLUSION： The results suggest that patients undergoing orthodontic treatment have more symptoms and signs of TMD in the time ranged.
