Silver Diamine Fluoride has been accepted as one of the minimally invasive options for the management of dentinal caries. Caries arresting property and the remineralizing ability of SDF have gained the attention and acceptance of dentists. The adverse effects of SDF documented are the unaesthetic dark stains and transient mucosal lesions. This could be attributed to the viscosity of the material, hence SDF in gel form would serve the purpose. To evaluate how the microhardness of natural impacted dentin is affected by Kedo SDF gel. A total of 10 samples were allocated to one of the 2 groups where Group A served as a Control receiving no SDF application whereas the samples in Group B received Kedo SDF Gel Application according to the manufacturer’s instructions. Vickers microhardness was tested using the Shimadzu HMV-G31DT micro-Vickers hardness tester. The values were recorded and analyzed using the paired t-test in SPSS software. The impacted natural dentin's microhardness was raised using Kedo SDF gel. Nevertheless, p = 0.3274 (p > 0.05) indicated that those findings weren't of statistical importance. Within the constraints of this investigation, it can be said that Kedo SDF-treated dentin surfaces had a higher micro-hardness than non-SDF-treated surfaces, albeit the differences were not statistically noteworthy.
