51例（平均年龄47.3岁）中重度牙周病患者和40例（平均年龄48.9岁）磨牙相关症状（咬合功能异常，如磨牙和/或咬合）患者在牙周状况和下颌功能障碍的体征和症状方面进行了比较。磨牙患者比牙周病患者报告更多的疼痛和咀嚼系统功能障碍症状。磨牙组临床功能障碍指数明显高于磨牙组，两组间的咬合状况变化相似，但磨牙组的咬合磨损更为明显。磨耗总体上与牙槽骨高度呈正相关。与其他牙齿相比，犬齿的这种相关性更强（而且在统计上也很显著）。磨耗与牙齿活动性呈负相关。结论：中重度牙周病患者与磨牙/咬合功能不全患者在下颌功能障碍的体征和症状上存在明显差异。结果支持牙周病与磨牙之间、磨牙与咬合状态之间没有或只有微弱相关性的观点。
Fifty-one patients (mean age, 47.3 years) with moderate to severe periodontal disease and 40 patients (mean age, 48.9 years) with symptoms related to bruxism (occlusal parafunctions such as grinding and/or clenching of the teeth) were compared with regard to periodontal conditions and signs and symptoms of mandibular dysfunction. The bruxists reported more symptoms of pain and dysfunction of the masticatory system than the periodontal patients. The clinical dysfunction index was significantly higher among the bruxists, while there was a similarity between the groups in the variation of occlusal conditions, except for occlusal wear, which was more pronounced in the bruxist group. Attrition was in general positively correlated to alveolar bone height. This correlation was stronger (and statistically significant) for the canines than for other teeth. Attrition was negatively correlated to tooth mobility. It is concluded that patients with moderate to severe periodontal disease and patients with bruxism/occlusal parafunctions are distinctly different with regard to signs and symptoms of mandibular dysfunction. The results support the opinions that there is no or only weak correlation between periodontal disease and bruxism, and between bruxism and occlusal status.
