Temporomandibular disorders (TMD) account for the most common orofacial pains rising from musculoskeletal origin. The aim of this study was to investigate the level of knowledge, attitudes and practice of dental practitioners regarding TMD in Tehran, Iran.
A questionnaire, containing 29 questions on etiology, signs and symptoms, diagnosis and treatment of TMD, was given to 200 randomly selected general dental practitioners and specialists as well as 11 TMD ex-perts.
An overall response rate of 97% was achieved among participants (mean age: 39 ± 8.2 years old; mean years in practice: 11.5 ± 7.4). The mean score of knowledge of TMD was found to be 10.85± 2.54 (of a total of 23). TMD specialists were significantly more knowledgeable than general dental practitioners (p<0.05). With respect to attitude, there was a significant difference among various age groups, and by increasing age and years in practice, the attitude towards TMD had weakened. However, no significant difference was recorded between general dental practitioners' attitude and that of TMD experts towards TMD. There was a positive correlation between subjects' knowledge and attitude (P= 0.007, r=0.138).
According to the results, the level of knowledge and attitude of general dental practitioners of Tehran regarding TMD is not desirable. The majority are not willing to admit and treat TMD patients.
颞下颌关节紊乱病（TMD）是肌肉骨骼源性最常见的口腔颌面部疼痛。本研究旨在调查伊朗德黑兰牙科从业者对TMD的知识水平、态度和实践情况。
向200名随机抽取的普通牙科从业者、专科医生以及11名TMD专家发放了一份包含29个关于TMD病因、体征和症状、诊断及治疗问题的问卷。
参与者的总体回应率为97%（平均年龄：39±8.2岁；平均从业年限：11.5±7.4年）。TMD知识的平均得分为10.85±2.54（满分23分）。TMD专科医生的知识水平显著高于普通牙科从业者（p<0.05）。在态度方面，不同年龄组之间存在显著差异，随着年龄和从业年限的增加，对TMD的态度有所减弱。然而，普通牙科从业者和TMD专家对TMD的态度之间没有显著差异。受试者的知识与态度之间存在正相关（P = 0.007，r = 0.138）。
根据研究结果，德黑兰普通牙科从业者对TMD的知识水平和态度不理想。大多数人不愿意接纳和治疗TMD患者。
