Fluoride mouth-rinsing programme is widely spreading over districts where the fluoride concentration in the drinking water is low or the fluoridation of communal water can not be realized, as a relatively easy and effective method of inhibiting dental caries. The most commonly used fluoride mouth-rinsing solution for daily use is a neutral 0.05% NaF solution (225ppm F). The rationale for this concentration, however, is not so clear. It is necessary, therefore, to investigate whether a weaker fluoride solution would have sufficient cariostatic effect. If it does, we could select the weaker solution and practice caries prevention with more safety.<BR>The present study was carried out in two elementary schools in the same district. The experimental group (school A) rinsed daily with a weakly acid (pH 5.0) sodium fluoride solution (100ppm F) at school under supervision and was given a routine school-based dental health administration. On the one hand, the control group (school B) was given the same dental health administration but without fluoride mouth-rinsing. The children of school A were instructed to rinse with 10ml of solution every school-day except Saturday, following the tooth brushing after lunch. Rinsing supervised by teachers was performed for 30 seconds (about 200 times per year). The dental examination was performed by trained dentists under standardized conditions as to light, mirrors, and explorers. The effects of rinsing were determined prospectively by comparing the dental caries experience of the children who had continuously participated in this study from the 1st to the 6 th grade, 79 children in school A and 63 children in school B.<BR>The results of rinsing with the weaker solution showed significant inhibition of dental caries. After 6 years, the caries reduction in children of school A was about 50% in the mean DMFT, which was statistically significant (p<0.001). It was also observed that the fluoride mouth-rinsing confers superior benefits to smooth surfaces than to surfaces having pits and fissures, as previously reported. The cariostatic effect on the first molars was not so great as on other teeth.<BR>To provide greater topical benefits for permanent teeth, therefore, it is necessary to start rinsing as early as possible. It may be considered that the age of 4 or 5 years is the time of choice in the beginning of rinsing. The results of this study suggest that fluoride mouth-rinsing with a weaker NaF solution is a practical and suitable method for school-based programs because of its efficacy and safety.
