Silver diamine fluoride (SDF) is an excellent tool currently used widely to treat and prevent dental caries. However, it involves the drawback of causing black stains which may be reversed by the application of Potassium iodide (KI) after SDF treatment. The current study aims to evaluate the effect of application of SDF and KI on the bond strength of GIC to eroded dentin. Thirty maxillary premolars were subjected to an acid-pH cycle, and their corresponding intervention. Group1:SDF followed by GIC; Group 2: SDF and KI followed by GIC; Group 3(Control): GIC alone. The microtensile bond strength was calculated with the universal testing machine (UTM). To test the comparison of bond strength between the groups, Kruskal Wallis One-way ANOVA test and Bonferroni multiple comparison test were used. The mean microtensile strength of Group 1 (SDF and GIC) was 5.15 MPa (±1.45), group 2 (SDF and KI followed by GIC) was 10.42MPa (± 2.07), as compared to Group 3 (GIC alone) 4.5 (±0.9). The application of KI significantly increased the bond strength between GIC and eroded dentinal surfaces treated with SDF.
