Post-treatment Benefits of School-based Fluoride Mouth-rinsing Program in Relation to Length of Participation.

Abstract

The purpose of this study was to evaluate the effects of a fluoride mouth-rinsing program (FMR) on dental health after the FMR program was completed. The state of dental health, including caries prevalence, was examined under blind recording conditions concerning participation in the FMR for 11th grade students in 10 public high schools, from 11 municipalities in Niigata Prefecture.The procedures of the FMR were carried out in these areas weekly, with 0.2% NaF, or daily, with 0.05% NaF, supervised by the classroom teachers in each school. The subjects, 321 in total, were classified into 3 rinse groups, each of which participated in the FMR for different periods of time, and a control group. The results of the statistical analysis showed increasing benefits in relation to increasing periods of participation. The reduction rate of caries prevention was the highest in the F11-group, subjects who participated in the program for 11 years from 4 to 14 years of age. The F11-group was 56.0% lower in the mean DMFT and 81.8% lower in the mean number of highly progressed carious teeth than the control group, with statistical significance in both cases. The percentage of students who had toothaches or who were absent from school in

Treatment and Posttreatment Effects of Fluoride Mouthrinsing after 17 Years

“…These findings suggest that the benefits derived by the treatment group were retained five years after rinsing had stopped. These results agree with those of other studies demonstrating two-to three-year posttreatment benefits from fluoride rinse (9,10,(13)(14)(15)(16)(17). Only a few studies have evaluated adults seven to eight years after discontinuation of a rinse regimen (18,191.…”

Effect of school-based fluoride mouth-rinsing on dental caries incidence among schoolchildren in the Kingdom of Tonga

“…Many reports have shown that fluoride use during the period of permanent tooth eruption is very effective for caries prevention. Some studies in Japan have shown a difference (%) of 33-51% in mean DMFT index among children who started FMR at age 6 years or older and 55-79% among children who started FMR at age 4-5 years or younger (FMR method: 0.2% NaF solution once per week and 0.05% NaF solution once per day, respectively) (11). Because the children in the FMR group began FMR at age 5 years, the school-based FMR program in Tonga may have a positive impact.…”

“…The results for each tooth surface were recorded after a visual examination with a dental mirror and exploration using sunlight or a flashlight. The items examined included number of sealant-treated teeth, number of C 0 and C 1-4 teeth, teeth missing due to caries, and number of treated teeth (5,10,11). Sealant-treated/ resin-filled teeth and healthy teeth were identified using erythrosine staining.…”
