Associação entre deglutição atípica e as maloclusões: uma revisão sistemática e metaanálise

Abstract

Objective: This systematic review aimed to answer the following focused question: Is there an association between atypical swallowing and malocclusions? Methodology: EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed / Medline, Scopus and Web of Science, Open Gray, Google Scholar and ProQuest Dissertations and Theses were like electronic databases. Two reviewers evaluated the studies for selection, extracted the data, the risk of bias was assessed by the Joanna Briggs Institute and GRADE tool was used to classify the certainty of the evidence. Meta-analyzes of random effects using mean difference (MD) and synthetic narrative were performed. Results: A total of 4750 articles were identified and, after a selection in two phases, four studies were included (three in meta-analyzes). All studies included moderate and high risk of bias, and the certainty of the evidence was considered very low. The values obtained in the meta-analysis for the association between posterior crossbite and atypical swallowing, demonstrated a risk of presenting atypical swallowing among respondents with posterior crossbite about 1.91 times (RR = 1.91; 95% CI = 1.45 - 2.50; I2 = 0%) in relation to orders without posterior crossbite (p <0.0001). Conclusion: The results indicate that atypical swallowing is associated with a posterior crossbite, however, conclusive evidence has not been found so far with other types of malocclusions.
