Effects of 38 Percent Silver Diammine Fluoride on Adhesive Shear Bond Strength of Resin Composite to Permanent Dentin: A Preliminary Assessment.

Purpose: The purpose of this study was to evaluate the influence of silver diammine fluoride (SDF) on shear bonding with total-etch adhesives. Methods: Thirty non-carious permanent human molars were collected and sectioned, exposing dentin that yielded two samples per tooth. Samples were mounted in resin, roughened, flattened to exposed dentine, and rehydrated (for 24 hours at 37 degrees Celsius). Fifteen samples were randomly allocated to each test group (n equals 15/gp): 3M™ Scotchbond™ Universal Plus Adhesive (SUPA), SDF+SUPA, Prime & Bond elect® Universal (PBE), and SDF+PBE. TPH Spectra® ST composite was utilized in all groups, light-cured, and rehydrated (for 24 hours at 37 degrees Celsius) before shear bond testing was performed. Maximum stress data were statistically analyzed using a two-way analysis of variance and Holm-Sidak post-hoc test (P<0.05). Results: Shear stress (MPa) were: SUPA (26.5±3.0), SDF+SUPA (25.6±7.2), PBE (21.1±5.7), and SDF+PBE (21.7±5.7). Statistically significant differences were only noted between SUPA and PBE (P=0.012). Conclusion: Within the limitations of this study, silver diammine fluoride did not affect the shear bonding of resin composite to dentin.
