Abstract:
Background: Resin-based sealers are widely used because they have good physical and biological properties and form micro-retention in dentin. There are also non-resin-based sealers. A non-resin-based sealer also has good micro-retention properties. The bond between dentin and the sealer can be improved by removing the smear layer. 2.5% NaOCl and 17% EDTA are the most common combination of irrigation solutions used to remove the smear layer. The use of 2% chlorhexidine after 17% EDTA at the end of irrigation will increase the antimicrobial effect and inhibit the activity of matrix metallo-proteinase (MMP). Objective: to determine push- out bond strength of obturation material with resin and non-resin sealers with 2.5% NaOCl, 17% EDTA and 2% CHX irrigation solution. Methods: The study used a true experimental method (post-test only group design). The treatment group (obturation with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only) were tested using a universal testing machine. Statistical tests using the Kruskal Wallis test and Mann Whitney test. Results: Kruskall Wallis test showed that there were differences value of push-out bond strength in different obturation material with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only (p <0.05). The Mann Whiney test showed a significant difference bond strength between the non-resin sealer obturationgroupandguttaperchaonlygroupandbetween betweentheresinsealerobturationgroupandgutta percha only group (p<0.05). Conclusion: The use of sealer (a resin-based sealer and non-resin-based sealer) and 2.5% NaOCl, 17% EDTA and 2% CHX as irrigation solution can increase the bond strength of the obturation material.
