Supervised weekly fluoride mouthrinsing programme with a 0.2 percent neutral sodium fluoride solution has been implemented at primary schools in Pusan, Korea since 1995. 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 and 9-year-old children not joining the programme 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.

The objective of the research was to evaluate the effect of caries prevention on deciduous teeth through caries activity tests and topical fluoride application to develop the efficient caries prevention strategy applicable to Korean children. First, the dental examination was done to detect caries for 2-6-year-old children at a children's house. The modified Snyder test to detect the ability of acid production by dental plaque using Snyder test medium and the test for the number of mutans streptococci in the saliva was applied to the 2-5-year-old children to predict the probability for future caries. With consideration of the results from caries activity tests, professional topical fluoride application and fluoride mouthrinsing therapy was applied for 1 year. More frequent fluoride application was used for the children who showed the higher probability of future caries. After 1-year preventive therapy, the effect of caries prevention on deciduous teeth was evaluated quantitatively by the caries activity tests and dental examinations. The results were as follows: 1. The reduction rate of dmfs index was 18.23% at 5-year-old children, 23.22% at 6-year-old children. 2. The reduction rate of pit and fissure surfaces among dmfs index was 19.62% at 4-year-old children, 13.53% at 5-year-old children, 6.92% at 6-year-old children. 3. The reduction rate of smooth surfaces among dmfs index was 21.57% at 5-year-old children, 34.52% at 6-year-old children. 4. The 1-year-increment of dmfs was significantly positive in proportion to dmfs index at basic examinations. 5. The dmfs index of basic examination was correlated significantly with the result of acid production test by dental plaque at 3-, 4- and 5-year-old children. The number of mutans streptococci in the saliva was significantly positively correlated with dmfs index of basic examination at 5-year old children. 6. The degree of acid production by dental plaque at basic examination was significantly positively correlated with the 1-year increment of dmfs index at 3- and 4-year old children. The number of mutans streptococci in the saliva at basic examination were significantly positively correlated with the 1-year increment of dmfs index at 5-year old children.

Flow through turbine flow meter is simulated by solving the incompressible Navier-Stockes equations. The solution method is based on the pseudocompressibility approach and uses an implicit-upwind differencing scheme together with the Gauss-Seidel line relaxation method. The equations are solved steadily in rotating reference frames and the centrifugal force and the Coriolis force are added to the equation of motion. The standard k-ε model is employed to evaluate turbulent viscosity.

Dental caries is the first disease to cause the pathological extraction of teeth in children. The complete prevention of dental caries is not achieved by toothbrushing alone. The use of fluoride and pit and fissure sealant is regarded as key tools to prevent dental caries. Fluoride-containing tablets or multi-vitamins and community water fluoridation can be used as systemic application techniques. Professional fluoride application, fluoride iontophoresis on teeth, fluoride mouth rinsing and fluoride- containing toothpaste can be used as local application techniques. Pit and fissure sealant is mainly used to prevent dental caries on occlusal surfaces of premolars and molars. Sweeteners not to occur dental caries has been developed to substitute sucrose. Dental erosion increases according to the high consumption of acidic soft drink or beverages. The appropriate use of fluoride and pit and fissure sealant are recommended to prevent dental caries effectively and the education is required to reduce the consumption of acidic soft drinks or beverages to decrease dental erosion.

The aim of this study is to assess the caries prevalence on permanent teeth and to collect the basic data for the development of dental health programmes for children in the primary school. The dental caries survey was carried out by a dentist from 1992 to 1997 for 3 primary school children in Masan and Changwon, Korea. The survey started when subjects were 6 years old. The total subjects were 463 at the beginning of this study in 1992 and decreased to 417 by the end of this study in 1997. The obtained results were as follows. 1, Children who experienced caries on permanent teeth increased from 20.3%(age 6) to 88.7%(age 11), Females had much higher caries prevalence than males in permanent teeth at every age. 2. For six years, substantial increases were seen in dental caries. DMFT scores increased from 0.38(age 6) to 4.57(age 11). DMFS scores increased from 0.51(age 6) to 7.12(age 11). Females' DMFT or DMFS scores were higher than males' at every age. 3. Dental caries on pits and fissures among DMFS scores were over 90% from 6-to 11-year olds. 4. The percents of Filled Teeth among Decayed, Missing, and Filled Teeth were 7.3% at 6-year olds and 27.0% at 11-year olds. 5. The most caries susceptible teeth were first molars. The percentage of sound first molars rapidly decreased from 6- to 11-year olds, Sound upper first molar decreased from 91.0%(age 6) to 33.9%(age 11). Sound lower first molar decreased from 84.0%(age 6) to 17.2%(age 11). 6. Community dental health programmes including use of fluoride and fissure sealants should be developed to prevent dental caries and school incremental dental care programme should be developed to treat children' s dental caries at the early stage.
