- Abstract
Purpose: The purpose of this study was to evaluate the effect of 38 percent silver diamine fluoride (SDF) application on the shear bond strength (SBS) of three types of bulk-fill restorative materials to dentin. Methods: Eighty recently extracted deidentified, sound, human premolar teeth were sectioned to expose the mid-coronal dentin. A composite restorative material (ACTIVA™), a giomer (Beautifil®), and a highviscosity glass ionomer (HVGI) cement (Equia Forte®) were used. The specimens were randomly assigned into eight groups (n equals 10 per group) according to the type of restorative material (ACTIVA™, Beautifil®, Equia Forte® with and without the conditioner) and pretreatment with one drop of 38 percent SDF. Both ACTIVA™ and Beautifil® were bonded to dentin with a universal adhesive (Scotchbond™ Universal). The SBS was measured in a universal testing machine with a 0.5 mm per minute crosshead speed. One-way analysis of variance, Tukey's, and adjusted pairwise comparison tests were used for statistical analysis of data (a equals 0.05). Results: Pretreatment of dentin with SDF did not affect the SBS of the tested bulk-fill materials (P>0.05). The SBS of the ACTIVA™ and Beautifil® groups was similar (P>0.05) and significantly higher than all Equia Forte® groups (P<0.001). Application of conditioner had no significant effect on the SBS values of Equia Forte® (adjusted P>0.01). Conclusions: The application of silver diamine fluoride did not influence the shear bond strength of tested bulk-fill materials to dentin. Prior conditioning did not affect the SBS of the high-viscosity glass ionomer to dentin. The giomer and composite restorative materials showed significantly higher SBS than high-viscosity glass ionomer.
