This study examined the effect of microflora and moistness of tongue on pyrexia and pneumonia in elderly people who require nursing care. In the analysis of data of long-term hospitalized elderly patients, subjects with many teeth in dentate patients and subjects with much tongue coating in edentate patients had higher risk for pyrexia. And, when we analyzed data of institutionalized and hospitalized elderly people, pattern of microflora of the tongue coating and moistness of tongue was closely related to pyrexia and pneumonia independently of dysphagia and other factors. These results suggest that evaluation of oral microflora may be an effective indicator not only for oral health but also for systemic health status.
