Aim: To evaluate the effect of different endodontic irrigation regimens on the sealing ability of resin composite restorations placed within the pulp chamber using contemporary simplified adhesives. Materials and Methods: Seventy-five extracted human molars were divided into six groups. After de-roofing the pulp chamber and extirpating the pulp, pulp chambers were bonded with either G-Bond after irrigation with saline (Group 1); ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl) (Group 2), and NaOCl + QMix (Group 3) or bonded with OptiBond adhesive after irrigation with saline (Group 4), EDTA and NaOCl (Group 5), and NaOCl + QMix (Group 6). All the samples were restored with composite. Ten samples per group were assessed for dye penetration. Fifteen samples were assessed under scanning electron microscope. Data were statistically analyzed using Mann–Whitney and Kruskal–Wallis tests at a significance level of P < 0.05. Results: Both EDTA + NaOCl or NaOCl + QMix pretreatment of pulp chamber dentin significantly reduced microleakage scores in adhesive OptiBond, but did not affect the microleakage of G-Bond. Conclusions: EDTA + NaOCl or NaOCl + QMix irrigation of the pulp chamber was not deleterious to the bonding of any of the adhesives tested.
