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.
