| Research Abstract |
Purpose: To evaluate the caries preventive effectiveness of a school-based fluoride mouth rinsing program as to whether it can decrease the number of decayed, missing and filled tooth (mean DMF teeth), considering some variables associated with the prevalence of dental caries. Subjects: 1,737 classes of grade 6th in elementary schools including 67,672 schoolchildren in Niigata prefecture, Japan in the years of2007-09. Results: The long-term fluoride mouth rinsing group (n=812, median value in the numbers of mean DMF teeth=0.36), in which more than 85.2% children had been participating in a school-based fluoride mouth rinsing program in elementary school for 5 years, had a significantly (42.1%) lower median value in the numbers of mean DMF teeth than the no fluoride mouth rinsing group (n=798, the median value=0.62), which had no experience of participating in fluoride mouth rinsing. Multiple regression analysisindicated that the fluoride mouth rinsing in the elementary schools, the fluoride mouth rinsing in the preschool facilities, and the years were the statistically significant variables.
