Abstract

STUDY OBJECTIVES

The coexistence of sleep-related breathing disorders (SRBD) and sleep bruxism (SB) is often mentioned in the literature. Polysomnography (PSG) with video recording gives the best opportunity to identify both of these phenomena. This study aimed to evaluate the relationship between SRBD and SB.

METHODS

Patients from the Clinic of Prosthetic Dentistry operating at Wroclaw Medical University with diagnosed probable SB were subjected to one-night video-polysomnography. PSGs were evaluated according to standard sleep criteria. The results of the examination were analyzed for the occurrence of SB and SRBD. The Bruxism Episodes Index (BEI) and the types of electromyographical pathways (phasic, tonic, mixed) were used to evaluate SB. The Apnea/Hypopnea Index (AHI) and Oxygen Desaturation Index (ODI) were used to assess respiratory events. Subjects were divided into two groups according to SB occurrence: the studied group (bruxers, BEI ≥ 2) and control group (non-bruxers, BEI < 2).

RESULTS

Quantitative analysis showed a lack of a statistically significant relationship between BEI and AHI (p = 0.82) and ODI (p = 0.90) in the studied group and controls. Qualitative analysis showed that the increase in both AHI and ODI was statistically significantly correlated with the increase in the number of tonic types of electromyographical pathways (p = 0.047, p = 0.006, respectively).

CONCLUSIONS

This study showed a significant relationship between tonic electromyographic pathways in SB episodes and SRBD. Tonic muscle contractions can be cause and effect for the formation of respiratory events. The occurrence of tonic episodes may be the key to understanding the causal relationship between SB and SRBD and should be more precisely examined.

摘要

研究目的

睡眠相关呼吸障碍（SRBD）与睡眠磨牙症（SB）的共存现象在文献中经常被提及。带有视频记录的多导睡眠监测（PSG）为识别这两种现象提供了最佳机会。本研究旨在评估SRBD与SB之间的关系。

方法

弗罗茨瓦夫医科大学口腔修复科确诊可能患有SB的患者接受了一晚的视频多导睡眠监测。PSG根据标准睡眠标准进行评估。分析检查结果中SB和SRBD的发生情况。使用磨牙发作指数（BEI）和肌电图通路类型（相位性、紧张性、混合性）来评估SB。使用呼吸暂停/低通气指数（AHI）和氧饱和度下降指数（ODI）来评估呼吸事件。根据SB的发生情况将受试者分为两组：研究组（磨牙者，BEI≥2）和对照组（非磨牙者，BEI<2）。
