INTRODUCTION: Surface roughness and microhardness are the two important properties which provide compressive strength as well as abrasion resistance to the restorative materials. On the other side topical fluorides provide the protective function with its anti-cariogenic properties. GIC as a restorative material fulfills both of the requirements.
AIM: The aim of this study is to evaluate the effect of topical fluoride application on surface roughness of various restorative materials.
MATERIALS AND METHODS: This study was done on 20 extracted teeth, Conventional Glass Ionomers (Fuji II) and Resin Modified Glass Ionomers (3M ESPE Vitremer) were used as restorative materials. Topical fluoride application i.e. with 2% sodium fluoride using Knutson’s technique was done followed by storing in artificial saliva for 24 hours and then blot dried for testing of surface roughness.
RESULTS: Through this study it was observed that the no statistical difference was found between both of the restorative materials. (P>0.05).
CONCLUSION: In oral environment strength and life span of restorative material is one of the important criteria and roughened surface can clinically deteriorate these properties of restoration. So it’s important for a dentist to consider all the factors while applying and restoring the tooth surface.
