Sodium Fluoride Varnish versus Silver Diamine Fluoride Effectiveness to Stop Dental Decay in Primary Molars

Objective: The aim of this study was to determine how well 38% SDF and 5% NaF varnish inhibited primary molar decay. Materials and Methods: 84 children between the ages of 6 and 9 who had caries without pulpal involvement in their primary teeth were included in the randomized controlled experiment. Children were divided between two groups at random. 5% NaF varnish was applied to Group 1 (n = 42), and 38% SDF was applied to Group 2 (n = 42). In both groups, the second application was completed six months later. Children were examined for caries arrest and recalled at 6- and 12-month. Results: After 6-month intervals, the rate of caries arrest was in group 1(NaF varnish – 40.4%) while in group 2 (SDF – 66.6%) and after 12-month intervals the rate of caries arrest was (NaF varnish – 47.6%) for group 1 and (SDF- 88%) for group 2 (p<0.05). Conclusion: The SDF group was shown to have higher caries arresting potential than the NaF varnish group.
