Effect of silver diamine fluoride and ammonium hexafluorosilicate applications with and without Er:YAG laser irradiation on the microtensile bond strength in sound and caries-affected dentin

Background and Objective Cariostatic and preventive agents are applied to create caries‐resistant dentin surfaces and may affect subsequent resin bonding. The aim of this study was to investigate the effect of different agents with and without Er:YAG laser irradiation on the microtensile bond streng...

Description
Summary:Background and Objective Cariostatic and preventive agents are applied to create caries‐resistant dentin surfaces and may affect subsequent resin bonding. The aim of this study was to investigate the effect of different agents with and without Er:YAG laser irradiation on the microtensile bond strength (µTBS) of resin composite to sound dentin (SD) and caries‐affected dentin (CAD), and to assess the morphological and chemical changes in the specimens. Materials and Methods Ninety‐six extracted molar teeth were divided into a control group (deionized water) and two experimental groups (ammonium hexafluorosilicate [SiF], silver diamine fluoride [SDF]), that subdivided according to different conditions (SD, CAD, SD+laser irradiation, CAD+laser irradiation). After treatment procedures, the teeth were restored and the µTBS was tested with a universal testing machine. Morover, 144 teeth were prepared and after treatment modalities; morphological changes of the surface were investigated and elemental analyses were performed using scanning electron microscope/energy dispersive spectroscopy (SEM‐EDS). The data were analyzed using Kruskal–Wallis and Mann–Whitney U tests. Results SDF and SiF applications reduced the µTBS values in both the SD and CAD subgroups (P
