Abstract

Objectives: The aim of this systematic review was to establish the adjuvant clinical effect of brushing with a dentifrice containing purported active ingredients as compared to a regular sodium fluoride dentifrice with respect to the inhibition of overnight dental plaque regrowth from studies with human participants. Methods: MEDLINE-PubMed, EMBASE and Cochrane CENTRAL were searched, up to June 2019. The inclusion criteria were controlled clinical trials with participants aged ≥ 18 years in good general health. Studies were included that evaluated the effect of toothbrushing with a dentifrice on the inhibition of overnight dental plaque regrowth when an active ingredient was added to the dentifrice as compared to a common sodium fluoride product. Data were extracted from the eligible studies, the risk of bias was assessed, and a meta-analysis was performed where feasible. Result: Independent screening of 213 unique papers resulted in 10 eligible publications that provided 14 comparisons. Stannous fluoride and triclosan dentifrices were found as the active ingredients. The descriptive analysis indicated that all, but two comparisons demonstrated an additional effect on the active-ingredient dentifrice. The meta-analysis supported and strengthened these findings. It showed that when plaque was scored digitally, a DiffM was −3.15(95% CI [−4.61:-1.69], P <.001, prediction interval [−5.07;-1.24]). When plaque was scored clinically, the difference of means (DiffM) was −0.33(95% CI [−0.49:-0.16], P <.001, prediction interval [−0.87; 0.21]). Conclusion: The results of this review demonstrate moderate-quality evidence that brushing with an active-ingredient dentifrice with stannous fluoride or triclosan does provide an added clinically relevant effect concerning plaque inhibition capabilities that surpass the effect of a regular sodium fluoride dentifrice.
