The objective of the current study was to evaluate the clinical utility of bruxism episode index in predicting the level of masticatory muscle pain intensity. The study involved adults (n = 220) recruited from the Outpatient Clinic of Temporomandibular Disorders at the Department of Experimental Dentistry, Wroclaw Medical University, during the period 2017-2022. Participants underwent medical interview and dental examination, focusing on signs and symptoms of sleep bruxism. The intensity of masticatory muscle pain was gauged using the Numeric Rating Scale. Patients identified with probable sleep bruxism underwent further evaluation through video-polysomnography. Statistical analyses included the Shapiro-Wilk test, Spearman's rank correlation test, association rules, receiver operating characteristic curves, linear regression, multivariate regression and prediction accuracy analyses. The analysis of correlation and one-factor linear regression revealed no statistically significant relationships between bruxism episode index and Numeric Rating Scale (p > 0.05 for all analyses). Examination of receiver operating characteristic curves and prediction accuracy indicated a lack of predictive utility for bruxism episode index in relation to masticatory muscle pain intensity. Multivariate regression analysis demonstrated no discernible relationship between bruxism episode index and Numeric Rating Scale across all examined masticatory muscles. In conclusion, bruxism episode index and masticatory muscle pain intensity exhibit no correlation, and bruxism episode index lacks predictive value for masticatory muscle pain. Clinicians are advised to refrain from employing the frequency of masticatory muscle activity as a method for assessing the association between masticatory muscle pain and sleep bruxism.
本研究的目的是评估磨牙症发作指数在预测咀嚼肌疼痛强度水平方面的临床效用。该研究纳入了2017年至2022年期间从弗罗茨瓦夫医科大学实验牙科系颞下颌关节紊乱门诊招募的成年人（n = 220）。参与者接受了医学访谈和牙科检查，重点关注睡眠磨牙症的体征和症状。使用数字评分量表来衡量咀嚼肌疼痛的强度。被确定可能患有睡眠磨牙症的患者通过视频多导睡眠图进行进一步评估。统计分析包括夏皮罗-威尔克检验、斯皮尔曼等级相关检验、关联规则、受试者工作特征曲线、线性回归、多元回归和预测准确性分析。相关性分析和单因素线性回归显示，磨牙症发作指数与数字评分量表之间无统计学显著关系（所有分析的p值均>0.05）。受试者工作特征曲线和预测准确性检查表明，磨牙症发作指数对咀嚼肌疼痛强度缺乏预测效用。多元回归分析表明，在所有检查的咀嚼肌中，磨牙症发作指数与数字评分量表之间没有明显关系。总之，磨牙症发作指数与咀嚼肌疼痛强度无相关性，且磨牙症发作指数对咀嚼肌疼痛缺乏预测价值。建议临床医生不要将咀嚼肌活动频率作为评估咀嚼肌疼痛与睡眠磨牙症之间关联的方法。
