Abstract
ABSTRACT Objective Anxiety tends to increase muscle tension and painful symptoms; however, its symptoms can be associated with temporomandibular dysfunction (TMD). Therefore, it is crucial for professionals to identify the presence of both comorbidities and determine whether they are related. This study aims to systematically evaluate the literature and answer the question: “Is there an association between anxiety and TMD in adults?” Methods The study followed the PRISMA protocol and was registered in PROSPERO. The custom search was performed in PubMed, Embase, Scopus, and Lilacs databases, as inclusion criteria observational studies that evaluated the association between anxiety and TMD in adults. Results A total of 1640 articles were found. After removing duplicates, 988 were evaluated by title and abstract. Of these, 28 were selected for reading in full, of which 13 were included in the present review. Conclusion The association of anxiety with TMD is positive, except for the minority indicating a low relationship between the disorders, which is explained by neuroscience.
