Evaluation of long-standing sleep bruxism (SB) patients.


Descriptive study.


One hundred subjects with SB (80 women and 20 men, mean age: 36.1+/-11.3 years) were evaluated according to the RDC/TMD and a pain questionnaire (EDOF-HC). The patients were divided into 2 groups: Group A-without (30.0%) and Group B-with orofacial pain (70.0%). AM stiffness: 36.4% in Group A and 88.6% in Group B; mean pain duration: 6.92 years; mean intensity of pain: 4.33 (VAS); quality of pain: tightness/pressure (84.3%); 95.7% of Group B had myofascial pain. Depression and somatization levels were different between the groups (p = 0.001). Higher frequency of depression was found with body pain or presence of comorbidities.


The data presented in this study showed statistical differences between long-standing bruxism without and with chronic facial pain; the two questionnaires allowed interaction between the chief complaint and the clinical findings; depression levels increased with pain in several regions of the body.
