项目摘要

Adult volunteers (subjects) were examined by use of an electromyogram (EMG) recording system along with a video recorder in their home. The occlusal splint was fabricated from a 1-mm-thick hard, transparent, plastic sheet adapted to a maxillary cast made of hard plaster with a pressure molding machine.For measurement of the salivary flow rate, the subject spat every 60 seconds into a preweighed cup for 5 minutes just after saliva swallowing. The measurements were done during relaxing, chewing-like movement, and clenching with or without splints. There were no significant differences in the salivary flow rates during any test movement with or without splints between the control and bruxism groups. In all subjects, the salivary flow rates with occlusal splints were significantly higher than those without splints during relaxing, chewing-like movement, and clenching. The salivary flow rates during chewing-like movement were significantly higher than those during relaxing and clenching, irrespective of the splint application. The salivary flow rates with splints during chewing-like movement were significantly higher than those without splints. There was no significant differences in the salivary flow rate during relaxing, irrespective of the splint application.In some subjects, the salivary flow rates with splints were significantly higher than those without splints. In others, they were not significantly higher. In some subjects of the former group, occlusal splint at night increased an average of pH in the lower esophagus. The frequency of GER (Gastroesophageal reflux) and RMMA (Rhythmic Masticatory Muscle Activity) significantly decreased.The results suggest that reduction of bruxism frequency with splints might be associated with the increase of an average of pH in the lower esophagus.

成年志愿者（被试）使用肌电图（EMG）记录系统和家中的录像机进行检查。咬合夹板由1毫米厚的硬透明塑料片制成，适合于用硬石膏制成的上颌铸造，并使用压力成型机。为了测量唾液流速，受试者在吞咽唾液后每60秒向一个预先称重的杯子中吐口水5分钟。这些测量是在放松、咀嚼类运动和握紧时进行的，有或没有夹板。在有或没有夹板的任何测试运动中，对照组和磨牙组之间的唾液流率没有显著差异。在所有受试者中，在放松、咀嚼样运动和握紧时，有咬合夹板的唾液流量明显高于没有咬合夹板的唾液流量。咀嚼样运动时的唾液流率明显高于放松和握紧时的唾液流率，与夹板应用无关。在咀嚼样运动中，有夹板的唾液流量明显高于无夹板的唾液流量。在放松时，无论夹板的使用情况如何，唾液流速没有显著差异。在一些受试者中，有夹板的唾液流率明显高于没有夹板的受试者。在另一些国家，它们并没有明显升高。在前一组的一些受试者中，夜间咬合夹板增加了食管下部pH值的平均值。胃食管反流（GER）和律动性咀嚼肌活动（RMMA）的频率显著降低。结果表明，使用夹板减少磨牙频率可能与食管下段平均pH值的增加有关。
