The objective of this study was to evaluate the influence of occlusal condition and psycho-social factors to the onset and maintaining of occlusal discomfort. 13 patients of occlusal discomfort and 22 control subjects were participated. We measured occlusal contact point, occlusal force, psychological status and character and factors of daily life by using occlusal registration film, dental prescale, self-rating questionnaire respectively. As a result, in the number of the occlusal contact points, biting force and occlusal contact area were significantly low compared to control group. The significant difference was not recognized between both groups about a score of anxiety, depression, extrovert and neurotic character. When we divided a level for anxiety and depression into diagnostic category, depression was significantly higher in patients group by multiple comparisons. Both group exhibited high ratio in "being busy", "exact work" and "presence of concerns" with daily life contributing factors. "Habit of biting" and occlusal force were extracted as significant predictors of assuming the group of patients by multiple logistic regression analysis. The psychological factor did not consist of logistic-regression analysis with a predictor. This study results revealed that complex of occlusal, psychological and daily life factors are related to the onset and maintenance of occlusal discomfort. Further studies that evaluate more precise dynamic occlusal condition, character/temperament and an onset opportunity and a psychology state need be done as next step.

这项研究的目的是评估咬合状况和心理社会因素对咬合不适的影响。 13例咬合不适的患者和22名对照组受试者。我们分别使用咬合注册膜，牙科预定片，自我评价问卷，测量了咬合接触点，咬合力，心理状况和特征以及日常生活的因素。结果，与对照组相比，在咬合接触点的数量中，咬合力和咬合接触面积显着低。两组之间尚未认识到焦虑，抑郁，外向和神经质特征的显着差异。当我们将焦虑和抑郁水平分为诊断类别时，通过多次比较，患者组的抑郁症明显更高。两组在“忙”，“确切的工作”和“存在关注点”的情况下表现出很高的比例。提取“咬人”和咬合力的“习惯”作为通过多个逻辑回归分析假设患者组的重要预测指标。心理因素不包括带有预测因子的逻辑回归分析。这项研究结果表明，咬合，心理和日常生活因素的复杂因素与咬合不适的发作和维持有关。进一步评估更精确的动态咬合状况，性格/气质和发作机会和心理状态的研究需要作为下一步。
