TI  - Characteristics and response to treatment of posttraumatic temporomandibular 
      disorder: a retrospective study.
PG  - 6-17
AB  - Temporomandibular disorders (TMDs) are likely the most common cause of persistent 
      pain in the head and neck. Treatment for TMDs can be quite varied although, in 
      general, favorable treatment outcome is reported to be on the order of 75-80%, 
      regardless of treatment approach. However, it has been reported that patients 
      suffering from posttraumatic TMDs, and, in particular, patients who have been 
      involved in motor vehicle accidents (MVAs), do not respond as well to therapy. 
      Therefore, this study was undertaken to elucidate some of the historical and 
      clinical features of posttraumatic TMDs and to compare this with the features of 
      TMDs that developed independent of identifiable trauma. Furthermore, a comparison 
      between recovery rates in the two populations was undertaken as well as a 
      comparison of the treatment modalities used in the two groups. Fifty-two 
      posttraumatic TMD patients were compared to an age- and sex-matched population of 
      "routine" TMD patients whose conditions developed independent of trauma. 
      Treatment, consisting of various accepted modalities, ranged from 3 to 5 years 
      after the MVA, with progress assessed at each visit. The data indicate that 48% 
      of posttraumatic TMD and 75% of TMD patients reported recovery with treatment (p 
      less than 0.001). The posttraumatic TMD patients required significantly more 
      treatment than the control TMD population. The findings suggest further that 60% 
      of MVA TMD patients suffer from symptoms suggestive of affective disorder 
      compared to only 14% of TMD patients. In view of the above, it appears that 
      posttraumatic TMD patients do not respond to therapy as well as the control 
      subjects. While the mechanisms underlying this finding are not clear, it could be 
      related to a difference in underlying pathophysiology. The data showing that 
      posttraumatic TMD patients develop significantly more symptoms suggestive of 
      affective disorders than control TMD patients could imply that there is a 
      relationship between these findings that requires further study.
