项目摘要

THE PURPOSE OF THIS STUDY IS TO INVESTIGATE RELATIONSHIP BETWEEN UNCONSCIOUS OCCLUSAL TOOTH CONTACTS AND MYOFASCIAL PAIN. L35 PATIENTS WERE USED IN MUSCLE PALPATION TESTS WHICH WERE PERFORMED ACCORDING TO THE KROGH-POULSEN'S PALPATION SYSTEM. THE MUSCLES, IN WHICH THE PATIENTS COMPLAINED PAIN OR UNPLEASANTNESS WHEN PALPATED, WERE RECORDED.OTHER 8 ( 4 NORMAL AND 4 TMJ DYSFUNCTIONED ) SUBJECTS WERE USED IN OCCLUSAL TOOTH CONTACTS TEST. IN ORDER TO EXAMINE OCCLUSAL TOOTH CONTACTS IN THE HABITUAL OCCLUSAL POSITION, A RADIOTELEMETRY SYSTEM WITH A SMALL TRANSMITTER, BATTERIES AND A SWITCH WAS USED. THE SWITCH WORKS AROUND THE AREA OF CIRCLE WITH DIAMETER OF 100 M FROM THE POINT OF HABITUAL OCCLUSAL POSITION. THE ANALOGUE SIGNALS WHICH APPEAR ONLY WHEN UPPER AND LOWER TEETH TOUCH TOGETHER IN THE HABITUAL OCCLUSAL POSITION WERE STORED IN A VIDEO CASETTE TAPE. THEN THE SIGNALS ON THE TAPE WERE CONVERTED INTO DIGITAL DATA BY A A/D CONVERTER AND THE FREQUENCY AND THE DURATION OF THE OCCLUSAL TOOTH CONTACTS WERE CALCULATED WITH A PERSONAL COMPUTER. THE RESULTS WERE AS FOLLOWS:1. IN CASE WITH UNILATERAL PAINED PATIENTS, THERE WERE STATISTICALLY MEANINGFUL CORRELATION BETWEEN UPPER AND LOWER STERNOCLEIDOMASTOID MUSCLES, INSERTION OF TEMPORAL MUSCLE AND INTERNAL PTERYGOIDMUSCLE, PROFOUND AND SHALLOW PARTS OF MASSETER MUSCLES, ANTERIOR PART OF TEMPORAL MUSCLE AND PROFOUND PART OF MASSETER MUSCLE, AND UPPER PART OF STERNOCLEIDOMASTOID MUSCLE AND LATERAL PTERYGOID MUSCLE.2. THE FREQUENCY AND THE DURATION OF TOOTH CONTACTS IN TMJ DYSFUNCTIONED PATIENTS WERE REMARKABLY GREATER THAN THOSE IN THE NORMAL SUBJECTS.

本研究的目的是探讨无意识牙合接触与肌筋膜疼痛的关系。L35例患者采用krogh-poulsen触诊系统进行肌肉触诊试验。在触诊时，病人抱怨疼痛或不愉快的肌肉被记录下来。其余8例（正常4例，颞下颌关节功能障碍4例）进行牙合接触试验。为了检查习惯性咬合位置的咬合牙齿接触，使用了一个带有小型发射器、电池和开关的无线电遥测系统。开关以习惯性咬合位置为中心，在直径为100米的圆形区域内工作。将上下牙在习惯咬合位置接触时产生的模拟信号存储在盒式磁带中。然后用a /D转换器将纸带上的信号转换成数字数据，用个人计算机计算牙合接触的频率和持续时间。实验结果如下：1.实验结果表明：单侧疼痛患者胸锁乳突肌上、下、颞肌、翼内肌止点、咬肌深部、咬肌浅部、颞肌前部、咬肌深部、胸锁乳突肌上部、翼外肌的相关均有统计学意义。2。颞下颌关节功能障碍患者的牙齿接触频率和接触时间均显著高于正常人。
