计算机辅助研究正畸治疗与颞下颌关节紊乱病关系

The computer-assistant study of the relationship between orthodontic treatment and temporomandibular joint disorders

目的 :探讨正畸治疗和颞下颌关节紊乱病的关系。方法 :设计调查表和相应的数据库 ,对 173例已正畸治疗者和 95例未治疗的错牙合患者进行颞下颌关节紊乱病的症状、体征及相关情况的问卷调查和专科检查 ,所得结果用数据库进行分析和统计。结果 :成功地建立了调查表和数据库 ;正畸组和错牙合组在主诉症状指数、临床症状指数和咬合指数的分布上都有显著性差异 (P <0 .0 0 1)。结论 :数据库在颞下颌关节紊乱病的临床研究中有较大的实用价值 ;

Objective: To study the relationship between orthodonti c treatment and temporomandibular joint disorders(TMD). Methods: The survey tables and their corresponding database were designed with the aid of computer. The questionnaire and clinical examination were administered t o 173 cases who had received orthodontic treatment (orthodontic group), 95 case s with morphologic malocclusion and without having orthodontic treatment ( maloc clusion group) and 32 cases with normal occlusion (normal group).Symptoms and s igns of TMD were collected,the data were analyzed with the databases. Results: The survey tables and their corresponding database were se t up. There were statistically significant differences between the orthodontic g roup and malocclusion group in the distribution of anamnestic, clinical dysfunct ion and occlusion indices (P<0.001).Heigher indices were found in the orthod ontic treatment group. Conclusion: This database is practi cal in the study of TMD. The results suggest that people with orthodontic trea tment have more symptoms and signs of TMD in the time ranged.
