A Study of Dental Health Status of Senior High School Students

Abstract

The school dental health activity is practiced mainly in primary schools and junior high schools in Japan.
But health education throughout every stage of life is very important.
The purpose of this study was to reveal the oral health status and to consider school dental health activity in senior high schools.
The students of a high school (SAITAMA Pref.) were given a dental examination in 1982 and 1987.
The following results were obtained;
1) There was no change in the mean DMFT between 1982 and 1987. But the mean MT was decreased in 1987.
2) The treated teeth rate increased and the caries prevalence rate of anterior teeth decreased significantly.
3) The PMA index of the anterior teeth decreased significantly.
4) Almost all subjects need the hygiene instruction and about 90% of the subjects need prophylaxis.
5) There were positive correlations between CPITN and DI-S or PMAindex of the anterior teeth.
6) We conclude that CPITN is very useful for the dental management of high school students and we discuss its application in public dental health practices.
