The aim of our study was the evaluation of seasonal influences on development and evolution of temporomandibular disorders (TMD). In a retrospective study based on data from 1997 and 1998, we analyzed the monthly number of patients at the Department of Prosthodontics. The total number of first time examinations during these two years was 11,747. Nine hundred and sixty-one (961) patients showed symptoms frequently found in TMD. These patients were submitted to a special TMD diagnosis based on the criteria of a validated craniomandibular index questionnaire. In 568 patients (group Al), a TMD was confirmed, in the other 393 patients (group A2), the disorder could not be confirmed. Dividing up the numbers of patients into summer and winter half years, we found statistically significant relationships between patient numbers and season in TMD patients (A1) as well as in all patients (group B). The distribution of the monthly numbers of TMD patients with its maximum in winter, however, was characteristically different from that of all patients with the maximum in summer. The number of TMD patients per month was significantly correlated to the mean daily sunshine duration per month. Parallels could be drawn to seasonal variations of symptoms in Seasonal Affective Disorders (SAD). As the mechanisms which influence the emergence of psychologically impacted disease in TMD patients might be comparable to SAD, we propose that a similar therapy may be applied.
