临床治疗中发现很多无牙病人有颞颌关节功能障碍(TMJD)的症状或体征,但尚未引起口腔科医师的普遍重视。本文对无牙颌人群中TMJD的发生作了调查研究;并对一定的症状、特征及临床决定性因素间的关系作了估价。材料与方法本文选择220例无牙颌患者,年龄在26～94岁之间,平均为63.5岁。其中138例戴有全口义齿,82例无义齿,在询问中除TMJ疼痛、杂音、及运动异常外,还有头痛、耳痛、眼痛或面肌痛都应视为TMJD的症状。检查包括开闭口中下颌骨的偏斜及与TMJ有关的肌肉的触诊和听诊杂音。结果从病史调查得知56例(25%)有症状,但仅有3例(1%)主诉为“TMJ问题”;3%发生TMJ疼痛;大多数TMJD的症状为头痛、耳痛、眼痛及面肌
Many clinical studies have found that many tooth-free patients have symptoms or signs of temporomandibular joint dysfunction (TMJD), but have not drawn the widespread attention of dentists. In this paper, the incidence of TMJD in edentulous people was investigated and the relationship between certain symptoms, characteristics and clinical determinants was evaluated. Materials and Methods In this paper, 220 cases of edentulous patients were selected, aged from 26 to 94 years, with an average of 63.5 years old. Among them, 138 cases had complete denture and 82 cases had no denture. In addition to TMJ pain, noise and abnormal movement, there were headache, earache, eye pain or facial muscle pain as symptoms of TMJD. Check palpation and auscultation murmur including skeletal opening and closing mandibular and TMJ-related muscles. Results Fifteen (25%) of the patients had symptoms from history surveys, but only three (1%) complained of “TMJ problems”; 3% developed TMJ pain; and most of the symptoms of TMJD were headache, earache, eye pain And facial muscles
