总结
本研究评估了85名受试者的夜间咬肌活动水平和下颌功能障碍症状，这些受试者的下颌功能障碍程度不同。采用综合颌功能障碍指数评价患者的疼痛主观报告以及颌功能障碍的临床检查证据。使用这一综合指数，夜间咬肌活动水平和颌骨功能障碍的体征和症状之间存在显着的相关性。牙齿磨损也与下颌功能障碍的体征和症状以及夜间咬肌活动（磨牙症）的高水平有关。
Summary
This study evaluated the level of nocturnal masseter activity and the symptoms of jaw dysfunction in eighty-five subjects who varied with respect to degree of jaw dysfunction. A combined jaw dysfunction index was employed which evaluated both the patients subjective report of pain as well as the clinical examination evidence of jaw dysfunction. Using this combined index, a significant correlation was found between the level of nocturnal masseter activity and the signs and symptoms of jaw dysfunction. Tooth wear was also related to signs and symptoms of jaw dysfunction as well as high levels of nocturnal masseter muscle activity (bruxism).
