The Effect of Silver Diamine Fluoride on the Bond Strength of Cements to Enamel and Dentin

This study investigated the effect of silver diamine fluoride (SDF) on the shear bond strength (SBS) of dual, light, and self-cured cement on enamel and dentin. Specimens were randomized into four groups (n = 32): G1, sound; G2, sound/treated with SDF; G3, demineralized; G4, demineralized/treated with SDF. Buildups were made using the following: dual-cured cement; RelyX Unicem (RXU); light-cured cement; Variolink Esthetic LC (VE); and self-cured cement Ketac Cem Maxicap (KetC). The SBS was performed, and data were analyzed using ANOVA models followed by Tukey’s test (α = 0.05). Enamel (E) had a significantly different SBS value (p < 0.001), (11.6–19.9 MPa) than dentin (D) (7.2–14.8 MPa), except for the KetC group (D: 3.1–5.1 MPa, E: 3.4–3.7 MPa), apart from G3 (E: 3.8 MPa, D: 3.1 MPa). In E/D, RXU had a more significant SBS value (p < 0.001), (11.5–19.9 MPa), followed by VE (7.2–15.4 MPa), then KetC (3.1–5.1 MPa). All groups within VE/E were more significant (p = 0.035) than G2. However, G4 in KetC/D was more significant (p < 0.001) than G1 and G2, which were more significant than G3. Enamel had a more significant SBS value than dentin in RXU and VE cements. RXU had significant strength, followed by VE, then KetC cements. SDF decreased the SBS of VE cement on sound enamel. However, it increased the SBS of demineralized dentin with KetC cement.
