福岡県久山町における歯科保健活動 昭和６１年度までの経過報告

Abstract

This program for dental caries prevention was started in Hisayama-cho, a suburb town of Fukuoka city in April, 1984. Younger inhabitants ranging from 1.5 to 15 years of age were subjected to the program. The dental health program consisted of dental hygiene instruction and fluoride application. The 1.5 to 3 year age group were recalled every 3 months after the initial dental examination and received dental health instruction, dental examination, and topical fluoride application with APF gel. Kindergarteners and primary school children received fluoride mouth rinsing with 0.2% NaF once a week, dental health instruction and dental examination twice a year. Junior high school students received dental health instruction and dental examination once a year.Comparing the improvement of dental health status between 1984 and 1986, it was found that dental caries prevalence decreased in all age groups of subjects, particularly in the lower grade children in primary school. The DMFT index and DMFS index in 1986 decreased to approximately one half compared with those of 1984. And the dft index of age group of 3 decreased from 4.17 to 2.40, and the DMFT index of age group of 12 decreased from 5.13 to 4.36.Presumptive calculation of cost for caries treatment was estimated from the chart of dental examination in primary school. Thus, the cost for caries treatment was calculated by using the standard that was made from the table of numerical rating of the health insurance issued on April, 1986. It was estimated from the survey that an amount of 4, 500 yen per child in primary school was saved in this dental health service for 2 years.In conclusion, the caries reducing effect during 2 years by this program was evaluated, and further effects will be attained by the continuation of this program in future.
