The Evidence
Article by Licini: Of the 362 subjects evaluated, 308 met the inclusion criteria. This study is based on Research Diagnostic Criteria for TMD (RDC/TM) Axis II diagnosis and analysis of gender-related differences. There was a ratio of 4 females to 1 male in the patient group.Article by Vedolin: 2 Groups of female students (No males in study). Group 1 had 29 patients presenting with masticatory myofascial pain (MFP), according to the Research Diagnostic Criteria for Temporomandibular Disorders. Group 2 had 16 asymptomatic controls. An electronic algometer registered the pain thresholds on four different occasions throughout the academic year. To measure levels of stress, anxiety and pain, the Beck Anxiety Inventory, Lipp Stress Symptoms Inventory and Visual Analog Scale (VAS) were used. Levels of anxiety and VAS were compared using Mann-Whitney test, while Friedman’s test was used for the within-groups comparison at different times (T1 to T4). The chi-squared and Cochran tests were performed to compare groups for the proportion of subjects with stress (alpha = 0.05). Differences in PPT recordings between time (P = 0.001) and sites (P < 0.001) were detected. Higher levels of anxiety and lower PPT figures were detected at T2 (academic examination) (P = 0.001). There was no difference between groups for anxiety and stress at any time (P > 0.05). The MFP group also has shown significant increase of VAS at the time of academic examination (P < 0.001)
Applicability These studies would apply to any patient that has TMD symptoms or any patients who feel extreme anxiety. It shows the relation between stress and TMD symptoms and can help Dentists relate that information to patients with these symptoms.

A PubMed and Trip database search on this question in November, 2015 found a more recent publication by Oliveira et al 2015 (PMID: 26039910). This clinical survey was conducted among nursing professionals in a university hospital, to evaluate the association between TMD, anxiety, quality of sleep and quality of life among the subjects. TMD was associated with trait anxiety and its severity was associated with state anxiety. The results further strengthens the conclusion of this CAT.
