Professionally-applied topical fluoride treatments are efficacious in reducing prevalence of dental caries. The most commonly used agents for professionally-applied fluoride treatments are five percent sodium fluoride varnish (NaFV;
22,500 ppm F) and 1.23 percent acidulated phosphate fluoride (APF; 12,300 ppm F). The efficacy of fluoride varnish in primary teeth when used at least twice a year has been reported in at least four randomized controlled trials.
The efficacy of fluoride varnish in permanent teeth, applied at three or six month intervals, also has been reported in at
least four randomized controlled trials. Meta-analyses of 14 placebo-controlled trials show that fluoride gels, applied
at three month to one year intervals, are efficacious in permanent teeth.23 Some topical fluoride gel and foam products are marketed with recommended treatment times of less than four minutes, but there are no clinical trials showing efficacy of shorter than four-minute application times. There also is limited evidence that topical fluoride foams are efficacious. Children at increased caries risk should receive a professional fluoride treatment at least every six months. As the risk categories may change over time, the type and frequency of preventive interventions should be adjusted.
