Abstract
Supervised weekly fluoride mouthrinsing programme with 0.2 percent neutral sodium fluoride solution has been implemented at primary schools in Pusan, Korea since 1995. 260,734 children of 259 schools join the fluoride mouthrinsing programme in 1999. To estimate caries preventive effect, epidemiological dental survey was undertaken in 1999 for 10-year-old children joining the fluoride mouthrinsing programme for four school years until 1998 and 10-year-old children not joining the programme until 1998. Subjects were 322 children joining the programme and 512 children in control schools.
The obtained results were as follows.
1. Children who experienced caries on permanent teeth were 73.6% in fluoride mouthrinsing group and 83.2% in control group.
2. The DMFT scores were 2.67 in fluoride mouthrinsing group and 3.49 in control group. The difference of DMFT scores was 0.82 between fluoride mouthrinsing group and control group. The caries reduction rate was 22.9% by fluoride mouthrinsing programme.
3. Filled teeth among total DMFT scores were 37.2% in fluoride mouthrinsing group and 32.2% in control group.
4. The caries reduction rates were comparatively high at anterior teeth and the lowest at upper and lower first molars by fluoride mouthrinsing programme.
5. The percentages of sound teeth at upper lateral incisors, upper and lower first premolars, upper second
premolars, upper and lower first molars and upper and lower second 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.
