Surface roughness of fluoride-releasing restorative materials after topical fluoride application

Abstract

Aim The aim of this study was to assess the effect of a single application of two topical fluoride agents: NNaF and APF (2% neutral sodium fluoride gel and 1.23% acidulated phosphate fluoride gel, respectively) on the surface roughness (Ra) of Fuji IX GP, Ketac N100, Vitremer, Dyract AP, Compoglass F and Filtek Ultimate. Study Design: The effect of NNaF and APF on the surface roughness of fluoride-releasing restorative materials was tested on disk-shaped material specimens with a surface profilometer.
