IMPACT OF SODIUM FLUORIDE AND NANO SILVER FLUORIDE-BASED VARNISHES ON REMINERALISATION OF ENAMEL CARIES: AN IN-VITRO STUDY

The present study aimed at comparative evaluation of 5% Sodium fluoride varnish, neutral nano silver fluoride (NSF) varnish and acidulated nano silver fluoride (NSF) varnish in remineralising artificially induced enamel caries of primary teeth. Thirty-nine primary anterior teeth were sectioned 2mm below the CEJ and mounted in acrylic resin blocks. Incipient enamel caries were induced on the samples artificially and primary Vicker’s surface microhardness (SMH) was assessed. Samples were divided equally and applied varnishes; Group 1: 5% Sodium fluoride varnish; Group 2: Neutral NSF varnish, and Group 3: Acidulated NSF varnish. A pH cycling protocol of 7 days was followed, and second SMH testing was carried out. The readings for the same are mentioned in the dataset from which the results were drawn. <br>
