In order to get information of the oral health status, decayed / missing / filled teeth and community periodontal index of treatment needs were evaluated by using thirty adult patients, aged 26-77 years, undergoing maintenance dialysis in a general hospital in Akita Prefecture. The mean numbers of teeth of patients, aged 26-39 years ,40-59 years, and 60-77 years, were 22.4, 14.3, and 10.6 respectively. The mean numbers of intact, decayed and filling teeth decreased with age, and particularly the decreased number of intact teeth was higher than that of decayed and filling teeth. On the other hand, the mean number of missing teeth increased with age.
All the patients were suffering from periodontal disease. The rate of patients with periodontal pockets decreased with age. The percentages of patients, aged 26-39 years and 60-77 years with shallow pockets, were 80% and 42% respectively, while those of patients, aged 40-59 years and 60-77 years with deep pockets, were 31% and 8% respectively. The rate of patients with no teeth or with no functioning teeth in the sextants increased with age. The mean numbers of sextants with calculus and with periodontal pockets decreased with age, but that of sextants with no teeth or with no functioning teeth increased with age. All patients required both improvement in personal oral hygiene and scaling. The percentages of patients, aged 40-59 years and 60-77 years, requring a high level of treatment, were 40% and 17% respectively. Increased tooth loss over 40 years might be attributed mostly to the progression of periodontal disease rather than to that of carious lesion.
