The aim of the study was to evaluate the relationship between bruxism, and sociodemographic parameters, symptoms of temporomandibular disorders (TMD), personality and war experience among Croatian navy employees. The sample included 1092 subjects, aged 20-60 years (mean age 37·06 ± 7·85). An individual's bruxism status was based on clinical oral examination and participants' report of bruxism. Subjects with bruxism index values ≥ 90th percentile were included in severe bruxism group (n = 111), and those with scores below 90th percentile were labelled as negligible bruxism group (n = 981). No differences were found in gender distribution between the two groups. The proportion of military personnel presenting with bruxism is double the proportion of administrative employees with bruxism. A total of 23·34% subjects in negligible bruxism group and 48·65% in severe bruxism group participated in the war. Subjects in severe bruxism group presented more TMD-related signs and symptoms than those in negligible bruxism group. Higher prevalence of neuroticism and psychoticism was found in severe bruxism group. According to logistic regression, the probability of severe bruxism was significantly associated with marital status [Odds ratio (OR) 6·859, 95% confidence interval (CI) 3·869-12·158 P < 0·001], neuroticism (OR 2·842, 95% CI 1·434-5·632 P = 0·003), psychoticism (OR 2·618, 95% CI 1·193-5·746 P = 0·016), military duty (OR 1·828, 95% CI 1·013-3·298 P = 0·045) and masticatory muscles tenderness (OR 9·372, 95% CI 4·923-17·841 P < 0·001). Smokers had a 2·72-fold (95% CI 1·706-4·335 P < 0·001) higher risk of bruxism than non-smokers. Subjects who participated in war were more represented in severe bruxism group. Further studies, including other potential risk factors, are required to clarify these relationships.
本研究旨在评估磨牙症与克罗地亚海军员工的社会人口学参数、颞下颌关节紊乱症状（TMD）、人格和战争经历之间的关系。该样本包括 1092 名年龄在 20-60 岁之间的受试者（平均年龄 37.06 ± 7.85 岁）。个体磨牙症的状态基于临床口腔检查和参与者对磨牙症的报告。磨牙症指数值≥90 百分位数的受试者被纳入重度磨牙症组（n=111），而得分低于 90 百分位数的受试者被标记为轻度磨牙症组（n=981）。两组在性别分布上无差异。有磨牙症的军人比例是行政员工的两倍。在轻度磨牙症组中，有 23.34%的受试者和在重度磨牙症组中有 48.65%的受试者参加了战争。与轻度磨牙症组相比，重度磨牙症组出现更多的 TMD 相关体征和症状。重度磨牙症组中神经质和精神病的患病率更高。根据逻辑回归，重度磨牙症的概率与婚姻状况显著相关[优势比（OR）6.859，95%置信区间（CI）3.869-12.158 P<0.001]、神经质（OR 2.842，95%CI 1.434-5.632 P=0.003）、精神病（OR 2.618，95%CI 1.193-5.746 P=0.016）、兵役（OR 1.828，95%CI 1.013-3.298 P=0.045）和咀嚼肌压痛（OR 9.372，95%CI 4.923-17.841 P<0.001）。与不吸烟者相比，吸烟者患磨牙症的风险高 2.72 倍（95%CI 1.706-4.335 P<0.001）。参加过战争的受试者更多地出现在重度磨牙症组。需要进一步的研究，包括其他潜在的风险因素，以阐明这些关系。
