    Aim: The aim of this in vitro study was to investigate and compare shear bond strength of Glass Ionomer cement to carious dentin of primary molars after the application of three different types of Silver Diamine Fluoride therapy: Silver Diamine Fluoride 38% (SDF), Silver Diamine Fluoride 38% with Potassium Iodide (SDF/KI), and Silver Fluoride Aqua with Iodide (AgF/KI). Materials and Methods: Extracted carious teeth were collected from Tufts University School of dental medicine. Sample size calculation was based on the pilot study results, total of 40 teeth were included and randomized into four groups (N= 10). Teeth were mounted and cut using Isomat saw, carious part of the tooth was exposed for the experiment. Control group: teeth received glass ionomer restoration. First test group received Silver Diamine Fluoride 38% (SDF), second test group received Silver Diamine Fluoride 38% with Potassium Iodide (SDF/KI), third test group received Silver Fluoride Aqua with Iodide (AgF/KI). Three test groups then received glass ionomer restoration and all four groups were tested for shear bond strength using Instron Machine. Mean and standard deviation were calculated, Welch’s ANOVA and the Games-Howell test for pairwise comparisons were used. Results: Comparison between control group of glass ionomer restoration used directly on dentin and all test groups of SDF therapy shows that shear bond strength is decreased when caries arresting medicaments used, regardless of the type. This reduction is statically significant. Conclusion: Within the limitation of this laboratory study, it can be concluded that SDF application in all three forms reduced shear bond strength of glass ionomer cements to extracted primary molars with natural caries.
