This study examines the association between personality traits and bruxism, the repetitive grinding or clenching of teeth. Community-dwelling participants (N = 470) had a comprehensive oral examination by a dentist and completed a dental history and personality questionnaires. Consistent with the literature on state anxiety and depression as antecedents of bruxism, Neuroticism-related traits were associated with self-reported teeth grinding. These traits were also associated with other oral complaints often associated with anxiety (jaw clicks, difficulty chewing food, and dry mouth), but not with more general oral health complaints (unhealthy gums, bleeding gums, and canker sores) or with dentist-assessed occlusal wear or tongue indentations. This study provides evidence for the association between Neuroticism and bruxism and other stress-related oral health symptoms.
本研究探讨人格特质与磨牙症(即牙齿反复研磨或咬紧)之间的关联。社区居住参与者(N = 470)接受了牙医的全面口腔检查,并完成了牙科病史和人格问卷。与将状态焦虑和抑郁作为磨牙症先兆的文献一致,与神经质相关的特质与自我报告的磨牙有关。这些特质还与其他通常与焦虑相关的口腔问题(下颌弹响、咀嚼食物困难和口干)有关,但与更一般的口腔健康问题(牙龈不健康、牙龈出血和口腔溃疡)或牙医评估的咬合磨损或舌痕无关。本研究为神经质与磨牙症以及其他与压力相关的口腔健康症状之间的关联提供了证据。
