Objectives
1 This study aims to compare the efficacy of the topical application of a 25% AgNO3 solution followed by a 5% NaF varnish with that of a 38% SDF solution, used as a positive control, in arresting dental caries in the primary teeth of preschool children when applied in half-yearly intervals over a 30-month period.
