Temporomandibular disorder pain in adult Saudi Arabians referred for specialised dental treatment.

The aim of this study was to determine the frequency of Temporomandibular Disorders (TMD) pain in Saudi Arabians, aged 20-40, who were referred to the Specialist Dental Centre in Makkah. The material included 325 patients (135 males, 190 females) who answered a history questionnaire. Patients reporting TMD pain in the last month were offered a clinical examination History questionnaires and clinical examinations were done according to the Arabic version of the Research Diagnostic Criteria for TMD (RDC/TMD). Fifty-eight patients (18%) reported TMD pain; 46 were clinically examined. Mean age of clinically examined TMD pain patients was 30 7 years with a male-female ratio of 1.6 (P < 0 001) All TMD pain patients had a diagnosis of myofascial pain, and 65% had diagnoses of arthralgia or osteoarthritis. Headaches or migraines in the last 6 months and headaches in the last month were reported in high frequencies in the TMD pain group, 93% and 71% respectively, with differences (P < 0.001) between the TMD pain and non-TMD pain groups. Graded Chronic Pain Scale assessments classified 45% of the TMD pain patients in grade 1,53% in grade II, 2% in grade III, and 0% in grade IV. Severe depression scores were found in 38% of the TMD pain patients and severe somatisation scores in 60% with differences (P < 0.001) between the TMD pain and non-TMD pain groups. In conclusion, the study found a frequency of TMD pain in this Saudi Arabian cohort of 18% The TMD pain group presented high scores of depression and somatisation but low disability grades on the Graded Chronic Pain Scale.
