RESUMEN
The study investigated the experience of depressive symptoms and the relationship with diffuse physical symptoms reporting in southern Chinese seeking professional care for temporomandibular disorders (TMD) in Hong Kong. Eighty-seven new patients [77 females/10 males; mean age 39.3 years (SD 12.7)] referred to the specialist TMD clinic at the Prince Philip Dental Hospital, Hong Kong participated in this study. The Research Diagnostic Criteria (RDC)/TMD history questionnaire was used to derive Axis II psychological data. Psychological status was assessed through depression and non-specific physical symptoms (NPS) scores (pain items included and excluded) measured with RDC/TMD Axis II instruments; 42.5% of patients experienced moderate/severe depression symptoms; 59.8% and 57.5% had moderate/severe NPS scores when pain items were included and excluded, respectively. Strong, positive and statistically significant correlations were noted between depression scores and the NPS scores that included pain items (r = 0.80) and those that did not (r = 0.80). The correlations remained consistent and were of similar magnitude when male patients were excluded from the computation and also when the possible effect of patient age was controlled. While taking into account the modest patient sample which was related to a low rate of treatment seeking, depressive symptoms were common and similar to other western and Chinese patient groups. NPS reports were higher than in Singapore Chinese patients. There appeared to be a clear association between depression and diffuse physical symptoms. The findings should be considered in the holistic care of Chinese people with TMD.

The study aimed to assess the distribution of temporomandibular disorders (TMD) sub-types, psychological distress and psychosocial dysfunction in southern Chinese people seeking treatment for TMD using Research Diagnostic Criteria for TMD (RDC/TMD) and investigate potential cross-cultural differences in sub-type prevalence and psychosocial impact. Eighty-seven consecutive patients (77 females; 10 males) with a mean age of 39.3 years (s.d. 12.8) newly referred to the specialist TMD clinic at the Prince Philip Dental Hospital, Hong Kong over a 20-month period took part in the study. RDC/TMD history questionnaire and clinical assessment data were used to derive Axis I and II findings. Group I muscle disorders were the most common and found in 57.5% of patients. Group II (disc displacement) disorders were found in 42.5% and 47.1% of the right and left temporomandibular joints (TMJ) respectively. Group III disorders (arthralgia/arthrosis/arthritis) were revealed in 19.5% and 23.0% of right and left TMJ's respectively. In the Axis II assessment, 42.5% of patients had moderate/severe depression scores, 59.7% had moderate/severe somatization scores and based on graded chronic pain scores 15.0% had psychosocial dysfunction (grade III and IV). While acknowledging the small sample size, the distribution of RDC/TMD Axis I and II diagnoses was fairly similar in Chinese TMD patients compared with Western and other Asian patient groups. However, in Chinese patients, myofascial pain with limited jaw opening and TMJ disc displacement with reduction were more common and a significant number experienced psychological distress and psychosocial dysfunction. The findings have implications for the management of TMD in Chinese people.
