EVALUATION OF REMINERALIZING POTENTIAL OF NANO SILVER FLUORIDE VARNISH ON ENAMEL CARIES LIKE LESIONS IN PRIMARY TEETH

Abstract

INTRODUCTION: Dental caries is a preventable chronic disease. Topical fluorides have been commonly used to manage caries. Nano silver fluoride is promising material in prevention and remineralization of early enamel caries in primary teeth. OBJECTIVES: To evaluate, in-vitro, the remineralizing potential of nano silver fluoride on enamel caries-like lesions in primary teeth in comparison to silver diamine fluoride and sodium fluoride varnish using energy dispersive x-ray spectroscopy (EDX). MATERIAL AND METHODS: Thirty-Two extracted or exfoliated caries free primary teeth were collected and coated with nail varnish leaving squares of 4x4 mm exposed enamel on labial surfaces. Caries like lesions were created by immersion in demineralizing solution for 4 days. Teeth were divided into four groups, group I (n=8) treated with nano silver sodium fluoride (NSSF), group II (n=8) treated with 38% silver diamine fluoride (SDF), group Ш (n=8) treated with 5% sodium fluoride varnish
