The methodology applied consisted of a quantitative cross-sectional study, where 113 patients aged between 20 and 45 years, with one or more symptoms of anxiety and/or temporomandibular dysfunction and/or sleep disorders. Volunteers answered the Beck-BAI, RDC/TMD and Fletcher & Luckett questionnaires for symptom analysis. The results showed that anxiety had a statistically significant influence on all evaluated variables of TMD and sleep disorders. Thus, it was concluded that the signs and symptoms of TMD and sleep disorders are influenced by anxiety.
