Effect of Silver Diamine Fluoride Treatment on Enamel/Dentin Bonding
Abstract
Objective: Silver Diamine Fluoride (SDF) is increasingly used to treat dental caries, but a preponderance of literature regarding its effects on adhesive dentistry is not observed. The purpose of this study is to evaluate the effect of SDF treatment on adhesion to enamel and dentin. Methods: 100 human caries free human third molars were sectioned at the cemento-enamel junction (CEJ) to remove the roots followed by mounting in auto-cure acrylic. Enamel and dentin bonding surfaces were prepared following ISO 29022 instructions for grinding/polishing of specimens and stored in 0.2M phosphate buffered saline (PBS). Specimens were randomly assigned into 10 groups (n=20). Using a shear bonding jig, a nano filled resin composite cylinder was bonded to each respective surface using a self-etch two step adhesive. Enamel and dentin groups consisted of: no SDF surface application (Control), testing Immediately after one SDF surface application (E1I, D1I), testing immediately after second SDF surface application (E2I, D2I), testing at one-month after one SDF surface application (E1D, D1D), and testing at one month after two SDF applications (E2D, D2D). All materials were used following manufacturer's instructions. The samples were tested to failure on a universal testing machine at a rate of one millimeter per minute with the failure load recorded in Newtons with the mean calculated. Specimens were also evaluated for failure mode using microscopy (20X). Mean failure load was analyzed using Kruskal-Wallis/Dunns post hoc at a 95 percent level of confidence (a=0.05).Results: Significant differences were found among the groups. For enamel specimens, E1I group had the highest bond strength, significantly above other groups. Followed by enamel control and E1D groups which were statistically higher than E2I and E2D groups. The dentin control and D1D were statistically higher than D1I, D2I and D2D groups.
