Sodium Hypochlorite as Fluorotic Dentin Pretreatment of Two-Step Self-Etch Adhesive with Silver Nanoparticle: Atomic Force Microscope and Adhesive Microtensile Bond Strength Evaluation
Table 2
Adhesion techniques for each study subgroup.
(1) Subgroup SE (control)
Primer of adhesive system Optibond Versa (SE) was applied with microbrush rubbing the surface of the dentin for 20 seconds as indicated by the manufacturer’s instructions.
(2) Subgroup NaOCl/SE
5.25% NaOCl to dentine surface was applied, rubbing for one minute, and then dried with absorbent paper and SE was applied for 20 seconds as explained above.
(3) Subgroup NaOCl/SE + NaAg
Dentine surface with 5.25% NaOCl rubbing for one minute and then drying with absorbent paper. Placed on a tray 5 μL of SE and 5 μL silver nanoparticle solution were added 0.1% (Martínez-Castañon, 2008); the mixture was brought to the dentin surface by rubbing with a microbrush for 20 seconds.
