Restoration of chewing ability is an important aspect of the treatment for temporomandibular disorders (TMDs). However, too little attention has been paid to it. We have used a questionnaire to evaluate and score the chewing ability of TMD patients. The questionnaire includes 19 kinds of food and a chewing task. The patient was asked if she/he experiences difficulty in enjoying eating. The aim of this study was to evaluate correlations between score of chewing ability (SCA) and other symptoms/signs of TMD. Four hundred and seventy-three consecutive TMD patients were evaluated for SCA and other symptoms/signs including temporomandibular joint (TMJ) pain, TMJ and muscle tenderness, TMJ noise (clicking and crepitus), and maximum mouth opening. The relationship between SCA and other symptoms/signs were analysed by multiple regression analysis. Score of chewing ability correlated significantly with TMJ pain and mouth opening capacity but not with TMJ noise and muscle tenderness. Age was a background factor but sex was not. The result of this study suggests that SCA correlated with dysfunction of the TMD patients. This method could be used to evaluate the ability of chewing in assessment of TMD.
咀嚼能力的恢复是颞下颌关节紊乱病（TMDs）治疗的一个重要方面。然而，对此关注过少。我们使用了一份问卷来评估和量化TMD患者的咀嚼能力。该问卷包含19种食物及一项咀嚼任务。询问患者在享受进食方面是否有困难。本研究的目的是评估咀嚼能力评分（SCA）与TMD的其他症状/体征之间的相关性。对473例连续的TMD患者进行了SCA及其他症状/体征评估，包括颞下颌关节（TMJ）疼痛、TMJ和肌肉压痛、TMJ弹响（咔哒声和摩擦音）以及最大开口度。通过多元回归分析来分析SCA与其他症状/体征之间的关系。咀嚼能力评分与TMJ疼痛和开口能力显著相关，但与TMJ弹响和肌肉压痛无关。年龄是一个背景因素，而性别不是。本研究结果表明SCA与TMD患者的功能障碍相关。该方法可用于在TMD评估中评估咀嚼能力。
