ROJAS-MARTINEZ, Cynthia  and  LOZANO-CASTRO, Felipe Enrique. Clinical diagnosis and psychosocial aspect of temporomandibular disorders according to the CDI/TTM index in dental students. Rev. Estomatol. Herediana [online]. 2014, vol.24, n.4, pp.229-238. ISSN 1019-4355.

Objectives: This study determined the relationship between diagnosis and psychosocial aspect of TMD as axis I and II of the Research Diagnostic Criteria for  Temporomandibular Disorders Index (RDC/TMD) in students of the school of Dentistry at Universidad Nacional Mayor de San Marcos, Lima (Peru) at 2013. Methods: The sample consisted of 76 students from 18 to 30 years old with diagnostic of TMD. Previously, a pilot study was applied with inclusion and exclusion criteria. Data were analyzed using descriptive statistics, the hypothesis was tested with the chi-square and Spearman correlation tests statistics using the SPSS 21.0. statistical package. Results: Axis I: muscle disorders occurred in 11.84 %, articular disc displacement in 55.3 % and other joint conditions in 32.9 %. For Muscle disorders and articular disc displacement women showed a higher prevalence, which was statistically significant (p = 0.006). The articular disc displacement with reduction was the most frequent diagnosis for the right joint with 31.6% and for the left 22.4 %. In relation to axis II; the most frequent grade for chronic pain was Grade I with 28.9 %, severe depression was 84.2 % y severe somatization was 77.6 %. There was a direct relationship between muscle disorders and chronic pain grade (Spearman correlation test Rho = 0.472; p= 0.000). Conclusions: A direct relation was present between muscle disorders and chronic pain condition. Disc displacement with reduction was the most frequent condition between TMD, predominantly in women.
