已知有许多不同的因素导致和延续了颞下颌关节紊乱病(TMD)的症状。然而，副功能因子的作用还没有清楚地阐明。我们在临床环境中发现了其中一个习惯。这种副功能习惯包括当嘴闭上时，每天轻触上下牙齿。我们称这种习惯为牙齿接触习惯(TCH)。[目的]探讨以下假设：1)TCH与TMD患者的慢性疼痛持续有关；2)TCH与其他行为因素有关。[方法]对229例慢性疼痛患者进行多因素Logistic回归分析。[结果]TCH的发生率为52.4%。抽搐和疼痛持续4个月以上的患者在首次就诊时疼痛改善的可能性较小(OR=1.944，p=0.043)。与TCH相关的其他因素有：单侧咀嚼(OR=2.802)和从事精密工作(OR=2.195)。[结论]TCH可延长TMD疼痛，并与其他行为因素有关。
Many different factors are known to cause and perpetuate the symptoms of temporomandibular disorders (TMD). However, the roles of parafunctional factors have not been clearly elucidated. We found one of these habits in the clinical setting. This parafunctional habit involves daily light touching of the upper and lower teeth, when the mouth is closed. We named this habit Teeth Contacting Habit (TCH). [OBJECTIVES] To investigate the following hypotheses: 1) TCH is associated with perpetuation of chronic pain of TMD patients; 2) TCH is associated with other behavioral factors. [METHODS] Two hundred and twenty-nine TMD outpatients with chronic pain were analyzed with multivariate logistic regression models. [RESULTS] TCH was found in 52.4% of patients. Patients with TCH and pain lasting for more than four months were less likely to experience improvements in pain at the first visit (OR = 1.944, p = 0.043). Other factors associated with TCH were as follows: unilateral chewing (OR = 2.802) and involvement in a precision job (OR = 2.195). [CONCLUSION] TCH can prolong TMD pain and is associated with other behavioral factors.
