Combined Topical Fluorides for Preventing Dental Caries in Children and Adolescents

Topical fluorides (mouthrinses, gels, or varnishes) used in addition to fluoride toothpaste are modestly effective in reducing caries compared to toothpaste used alone. Level of evidence: "A"

A Cochrane review [Abstract] 1 included twelve studies. Nine trials provided data for the main meta-analysis on the effect of fluoride mouthrinses, gels or varnishes used in combination with toothpaste (involving 4,026 children). In this meta-analysis, the pooled prevented fraction (PF) of decayed, missing and filled tooth surfaces (DMFS) was 10% (95% CI, 2% to 17%; p = 0.01) in favour of the combined regimens. Heterogeneity was not substantial in these results. The separate meta-analyses of fluoride gel or mouthrinse combined with toothpaste versus toothpaste alone favour the combined regimens, but differences were not statistically significant. The only other statistically significant result was in favour of the combined use of fluoride gel and mouthrinse in comparison to gel alone (pooled DMFS PF 23%; 95% CI, 4% to 43%; p = 0.02), based on two trials. No other combinations of topical fluoride therapy were consistently superior to a single therapy. In conclusion, topical fluorides (mouthrinses, gels, or varnishes) used in addition to fluoride toothpaste achieve a modest reduction in caries compared to toothpaste used alone.
