PubMed ID	Author / Year	Patient Group	Study type (level of evidence)
#1) 20027126	Licini/2009	308 subjects 4 female : 1 male	Case series (comparative)
Key results	Psychological characteristics, including somatization, depression, and anxiety related to gender, appear to have a significant impact on the prevalence of TMD.
#2) 19210679	Vedolin/2009	45 female students	Case control
Key results	External stressors have a potential impact on masticatory muscle tenderness, regardless of the presence of a previous condition such as masticatory myofascial pain.

Comments on
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.
