Abstract
ABSTRACT Objective This systematic review determined whether occlusal appliance use influences the sleep of individuals with sleep bruxism. Material and Methods Six databases and the gray literature were searched to identify randomized and non-randomized clinical trials comparing slow wave sleep and sleep quality of sleep bruxers before and after occlusal appliance use. The Risk of Bias was assessed using Cochrane tools and Meta-analyses were performed to compare data. The Certainty of the evidence was evaluated by Grading of Recommendations Assessment, Development, and Evaluation approach. Results Two randomized and eight non-randomized studies were included. Meta-analyses indicated that soft and hard appliances influenced the slow-wave sleep and sleep quality of sleep bruxers, as determined by polysomnography (Z = 5.58; p < .001), the Pittsburgh Sleep Quality Index (Z = 3.45; p < .001), and the Sleep Assessment Questionnaire (Z = 48.1; p < .001). Conclusion Occlusal appliance use significantly impacts slow-wave sleep and sleep quality in sleep bruxism individuals, regardless of appliance design or material.
