Evaluating the Effect of Silver Diamine Fluoride, with or without Glutathione and Potassium Iodide, on Fluoride Release, Dentin Microhardness and Surface Properties of Dentin

This study aimed to evaluate the effect of silver diamine fluoride (SDF) in combination with or without glutathione (Glu) and potassium iodide (KI) on the fluoride release and the enhancement of dentin microhardness. In this et al study, 90 intact premolar teeth from human subjects were allocated into nine groups, each consisting of ten samples: A) control; B) SDF; C) SDF combined with 5% Glu; D) SDF combined with 10% Glu; E) SDF combined with 20% Glu; F) KI after SDF; G) 5% Glu after SDF; H) 10% Glu after SDF; and I) 20% Glu after SDF. Data were analyzed using SPSS version 22 software and ANOVA and post-hoc and repeated measure test (P value
