Fluoride retention amounts following toothbrushing and mouthrinsing with a weak fluoride solution

다국어 초록 (Multilingual Abstract)

Objectives: The aim of this study was to determine the effectiveness of caries prevention from intraoral fluoride retention following tooth brushing with a weak fluoride solution.

Methods: Six subjects (average age is 37.5 years old) performed tooth brushing with a weak fluoride solution (100 ppm F as NaF) and fluoride mouth-rinsing (100 ppm F as NaF) as positive control just before going to bed on separate day. At the time of rising in the next morning, the subjects collected their unstimulated total saliva, and we examined salivary fluoride concentration. Two fluoride modalities were performed randomly each three times.

Results: The mean salivary fluoride concentrations upon arising were 0.07 ppm (range: 0.01 - 0.22 ppm) in tooth brushing with a weak fluoride solution experiments and 0.14 ppm (range: 0.02 - 0.37 ppm) in fluoride mouth-rinsing experiments.

Conclusion: Though salivary fluoride concentrations upon arising after tooth brushing with a weak fluoride solution was lower than after fluoride mouth-rinsing, it was higher than 0.05 ppm of optimal therapeutic level which enhances remineralization. The results suggested that tooth brushing with a weak fluoride solution just before going to bed was effective on caries prevention for young children. On the other hand, salivary fluoride concentrations after fluoride mouth-rinsing was significantly higher than tooth brushing with a weak
fluoride solution, since fluoride might be reserved on oral mucous membrane.
