| Outline of Final Research Achievements |
The aim of this study was to investigate the relationship between weather conditions and acute phase of temporomandibular disorders (TMD), glossodynia, and chronic periodontitis in patients. Patients who were diagnosed with acute phase of TMD, glossodynia or chronic periodontitis under supportive periodontal therapy were selected for this study. We performed oral examinations, and collected questionnaires, sympathovagal balance data, concentration of salivary cortisol and meteorological data. In TMD and glossodynia, although there were no association between weather conditions and their acute phases, sympathovagal balance was changed between stable and acute phases. In 153 patients who experienced acute phase of chronic periodontitis, when using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure and maximum hourly range of temperature were significantly associated with the occurrence.
