An epidemiological investigation of dental caries was undertaken between 1984 and 1990 of June for Nishi-Fukuoka Kindergarteners in Sawara District of Fukuoka City. The data obtained at three-year intervals were statistically analyzed. 1. The dt index was 7.1 in 1984,7.0 in 1987 and 5.6 in 1990. The ds index was 12.1 in 1984,10.0 in 1987 and 9.5 in 1990. The dt and ds index for the dental caries prevalence of deciduous teeth significantly decreased. 2. The ft index was 2.9 in 1984,3.3 in 1987 and 3.9 in 1990. The ft% index was 25.7% in 1984,31.8% in 1987 and 45.3% in 1990. Treatment of the dental caries in deciduous teeth had improved year by year. 3. In the frequency of the caries attack in deciduous teeth, the percentage of children in the A group which had caries. lesions in only maxillary anteriors or molars and mandibular molars and the O group which had no caries, had increased, and the CSI index decreased year by year. The prevalence of dental caries in deciduous teeth was alleviated. 4. Comparison to caries status reported by the Welfare Ministry in 1987,revealed that the percent of treated dental caries in deciduous teeth in Nishi-Fukuoka Kindergarteners was higher, but the prevalence of dental caries in deciduous teeth was also higher. The prevalence of dental caries in deciduous teeth was higher in our study than in the Welfare Ministry report. This indicates the importance of dental health education. 5. Tooth brushing status showed satisfactory results and amount of plaque was scanty. 6. Although Fukuoka is a big city, the percent of children living with grandparents and of those with a working mother increased year by year. The changes in the living environment of children and prevalence of dental caries requires special attention in the future.
