Abstract
We determined the prevalence of adult periodontal disease using the Community Periodontal Index of Treatment Needs (CPITN) conducted at the health promotion center in Agematsu-cho, Kiso, Japan.
Subject were 292 adults 104 men with a mean age of 61.2 years and 188 women with a mean age of 52.2 ears. Subjects were stratified by 10-year groups-20-39, 40-49, 50-59, 60-69 and 70 years. Dental examination involved counting intact treated, and untreated teeth and teeth requiring prosthetic appliances. We examined the correlation between the number of teeth and gender or age group and CPITN using Student's t test. We also studied the correlation between CPITN of each tooth versus gender or age group using the chi-square test. Oral hygiene was assessed and the oral hygiene score compared by gender and age the using chi-square test.
The numbers of present, intact, and treated teeth were not correlate with age. The number of present teeth in subjects over 60 years old group was significantly lower than in 20-39 year age group (p<0.01). CPITN score was higher with age in women (p<0.01) but not man. The number of subjects having poor oral hygiene increased with age (p <0.01).
Our results suggest that women over 60 years old require regular treatment for dental caries. All adult subjects in Agematsu should be treated for periodontal disease and instructed in oral hygiene. J Jpn Soc Periodontol 44: 178-187, 2002.
