Abstract

Background/objectives: Professional topical fluoride (F) gel application has been used to prevent dental caries with a concern about safety in young children. The aim of this study is to evaluate a paint-on technique using a No. 8 paint brush for applying professional topical F gel as an alternative method in children at a safer, lower dose compared with a tray. Materials and Methods: Twenty-one healthy children (12-15-year-old) participated in this clinical crossover study. The amounts of F gel used were 0.4 ml in the paint-on or 5.0 ml in the tray. Saliva and interproximal fluid were collected before, and immediately, 5, 10, 20, 30, and 60 min after application. F retention efficiency was evaluated by salivary flow rate, F concentration, F availability, and time half-life (t2). Results: The salivary flow rate induced by the two methods were similar. The F concentration and availability in the saliva and interproximal fluid in the paint-on technique was significantly higher than those in the tray technique. The t2 in the saliva and interproximal fluid in the paint-on technique were shorter than those in the tray. Conclusion: The novel paint-on technique effectively delivered topical F gel at a safe dose that would allow its use in young children, particularly those with a high caries risk.
