As society ages, the composition of the diseases that occur within it changes accordingly. With that in mind, we examined the characteristics and trends in the recent inpatients and compared these recent inpatients with those of a previous report to identify the changes that accompany the aging of society. Subjects were 1, 534 cases (men 56.9%, female 43.1%, average age 47.1 years) who were hospitalized at Kurume University Hospital for treatment during the 5-year period from January 1st, 1994 through December 31st, 1998. The ratio of inpatients over 65 years old was about 1.8 times higher than in the previous study, showing a clear trend toward an increased overall age of inpatients. As for the types of disease observed, the most common malignancies were epithelial tumor, followed by other benign tumors, as well as 76 cases which included diseases resembling tumor (epulis and exostosis etc.). A majority of the patients (55.6%) were directed to the Hospital by their dentist, a finding similar to that of the previous report. As for geographical distribution, 93.3% of the inpatients lived within 40 km of the center of Kurume City where our oral surgery is located, an increase of about 10% from the last report. In other words, our results showed a reduction in the sphere of treatment distribution.
