Abstract
-Abstract-
Supervised weekly fluoride mouthrinsing programme with a 0.2 percent neutral sodium
fluoride solution has been implemented at primary schools in Pusan, Korea since1995.
260,734 children of 253 schools join the fluoride mouthrinsing programme in 1998. To
estimate caries preventive effect, epidemiologic dental survey was undertaken in 1998 for
9-year-old children joining the mouthrinsing programme for three school years until last
year. Subjects were 367 children joining the programme and 248 children in control
schools.
The obtained results were as follows.
1. Children who experienced caries on permanent teeth were 65.9％ in fluoride
mouthrinsing group and 78.2％ in control group.
2. The DMFT scores were 2.10 in fluoride mouthrinsing group and 2.84 in control
group. The difference of DMFT scores was 0.74 between fluoride mouthrinsing group
and control group. The caries reduction rate was 26.1％ by fluoride mouthrinsing
programme.
3. Filled teeth among total DMFT scores were 35.2％ in fluoride mouthrinsing group and
24.4％ in control group.
4. The caries reduction rates were high at anterior teeth and low at upper and lower
first molars by fluoride mouthrinsing programme.
5. The percentages of sound teeth at upper first premolars and upper and lower first
molars in fluoride mouthrinsing group were significantly higher than control group.
6. The fluoride mouthrinsing programme should be developed at 4-to 5-year old children
in nursery schools and all children in junior high schools as well as all primary schools.
