Abstract
AIM: To determine whether Japanese preschool-aged children swallow fluoride solution while rinsing and how much fluoride was retained in the mouth after rinsing. METHODS: The subjects were 769 children who participated in a school-based fluoride mouth rinse programme (FMR) using 0.05% sodium fluoride solution daily. The group of younger, mean age of 4 years and 10 months, experienced the FMR for two months, and the group of older children, mean age of 5 years and 4 months, did it for at least 8 months, rinsing for a minute using 7 ml of the solution. The amount of fluoride retained in the mouth was estimated as the amount present in the net rinsing solution prepared minus what returned to the solution expectorated. RESULTS: No child swallowed all the solution. The rate of fluoride retained was 12.0% (mean = 0.19 mg) in the younger group and 10.7% (mean = 0.17 mg) in the older. Only six children retained over 0.5 mg of fluoride. With the extra survey using weekly intervals, the amount retained was below 0.5 mg in all children. CONCLUSION: That Japanese preschoolaged children could perform fluoride mouth rinsing safely and efficiently.
