Both temporomandibular disorders (TMDs) and sleep bruxism (SB) are known to be destructive to the masticatory system. However, the association between the 2 conditions is poorly understood. The aim of our study was to assess the relationship between TMD and SB through the signs and symptoms in 2 patient groups: TMD only and TMD with SB.
A retrospective chart review was conducted from November 1, 2015, to April 1, 2018, on patients with completed International Network for Orofacial Pain and Related Disorders Methodology history questionnaires and Diagnostic Criteria for Temporomandibular Disorder clinical examinations. Fifty-two patients, including 12 with TMD only and 40 with TMD with SB, met the study criteria. Subjective descriptions and objective measurements of patient symptoms were investigated. The χ test and Fisher's exact test were used for statistical analysis.
The TMD with SB group exhibited increased oral behaviors compared with the TMD-only group (P = .0004). The TMD with SB group also experienced more headaches compared with the TMD-only group (P = .045).
Our results revealed that patients with jaw pain who self-report increased oral behaviors and/or exhibit temporal headaches should be evaluated for sleep bruxism.
众所周知，颞下颌关节紊乱（TMD）和磨牙症（SB）都会对咀嚼系统造成损害。然而，这两种情况之间的关系尚未得到充分了解。本研究旨在通过两组患者（仅 TMD 和 TMD 伴 SB）的体征和症状评估 TMD 和 SB 之间的关系。
对 2015 年 11 月 1 日至 2018 年 4 月 1 日完成国际口腔颌面疼痛和相关疾病方法学病史问卷和颞下颌关节紊乱诊断标准临床检查的患者进行回顾性图表审查。符合研究标准的 52 名患者，包括 12 名仅 TMD 和 40 名 TMD 伴 SB。研究调查了患者症状的主观描述和客观测量。采用 χ检验和 Fisher 确切检验进行统计学分析。
与仅 TMD 组相比，TMD 伴 SB 组的口腔行为增多（P =.0004）。与仅 TMD 组相比，TMD 伴 SB 组还经历更多的头痛（P =.045）。
我们的结果表明，自我报告口腔行为增加和/或表现出颞部头痛的颌痛患者应评估磨牙症。
