Abstract

This study evaluated several dentin desensitizers' effects on dentin microtensile bond strengths (MTBS) of various self-etch (SE) and etch-and-rinse (ER) adhesives. For ER, dentin from human molars was phosphoric acid-etched, treated with a desensitizer, and coated with the adhesive. For SE, dentin was treated with the same desensitizers, and coated with the adhesive. Composite build-ups were placed and specimens stored in distilled water at 37°C for 24h. Specimens were sectioned into beams and tested either immediately or after 6 months. Data were analyzed using factorial analysis of variance. At 24h, mean MTBS's ranged from 20.0-46.6 MPa for ER and from 22.0-37.0 MPa for SE. At 6 months, mean MTBS's ranged from 22.0-45.4 MPa for ER and from 20.2-33.4 MPa for SE. The main factors (adhesive, desensitize
