Aim of the study: To compare the microleakage in teeth restored using silver diamine fluoride (SDF) and dental varnish under amalgam restoration. Materials and methods: Twenty premolar teeth were used in the study. Class I cavity was prepared and restored using silver amalgam. In group I, the dental varnish was used under restoration, and in group II, the SDF was used. All samples were tested for microleakage using methylene blue assay and evaluated under stereomicroscope. Results: Group I samples showed minimal microleakage when compared with group II with a p value <0.002. Conclusion: Silver diamine fluoride would not be an alternative to dental varnish.
