Alteração do padrão de sono em pacientes portadores de disfunção temporomandibular sintomática: uma revisão sistemática

Abstract

This study aims to summarize the results obtained from studies on sleep quality in individuals with symptomatic temporomandibular disorders. This systematic review followed PRISMA guidelines and was registered in the PROSPERO database. The search for data was carried out individually and in detail in the main electronic libraries, with no year limit, and observational studies were included, with language restriction in English and Portuguese. Data extraction was performed independently by two reviewers. The extractions, summarization, qualitative analysis and risk of bias assessment were performed using Newcastle-Ottawa Quality Assessment Scale [NOQA] for observational studies tools. 749 articles were selected, and after applying the eligibility criteria, 20 studies were selected for inclusion. The articles chosen included are between 2009 and 2021, and aim to answer the question in PICO format: “Do patients with symptomatic temporomandibular dysfunction present impairment in their sleep quality?” The risk of bias shows studies with low risk, and others with uncertainty or high risk. Of the 20 studies included for detailed analysis, 8 used polysomnography to investigate potential sleep disturbances and their relationship to pain levels. Of the 11 studies that used the Pittsburgh questionnaire, 11 reported an important impairment in sleep quality, and 3 evaluated tension headache by describing the correlation of TMD with anxiety. The results of this review suggest that sleep quality should be investigated in patients with TMD, and treatment positively influences pain resolution.
