Abstract
This study evaluated the prevalence of temporomandibular disorders (TMDs) in ballet dancers and explored their association with levels of anxiety. Participants were 51 male and female ballet dancers with a mean age of 31.5 ± 12.6 years. The diagnosis of TMDs was made in accordance with Research Diagnostic Criteria for Temporomandibular Joint Disorders (RDC/TMD). All subjects completed the state part of an anxiety questionnaire (STAI). Data were gathered and analyzed using the R statistical software (version: 3.4.0.) with level of significance set at 5%. The prevalence of all TMDs in the sample was 78%; that is, of the 51 participants, 39 had at least one positive diagnosis. The two most prevalence diagnoses were disk displacement with reduction and arthralgia. Individuals with TMD had a mean anxiety score of 42.55 ± 9.92 on the STAI, whereas for those without TMD it was 44.27 ± 11.89, with no statistically significant difference (p = 0.53). It is concluded that the general prevalence of TMDs in ballet dancer is higher than in the population at large. Disk displacement with reduction and arthralgia are the most common TMDs, and the presence of TMDs does not seem to affect anxiety state levels in this population.Keywords
