PENGARUH KOMBINASI LARUTAN IRIGASI TERHADAP KEKUATAN PELEKATAN SEALER RESIN DAN NON-RESIN PADA DINDING SALURAN AKAR

Abstract

ABSTRACTBackground: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 Whitneytest.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 obturation group and gutta percha only group and between between the resin sealer obturation group and gutta 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. Keywords:bond strength, non-resin based sealer, resin based sealer. ABSTRAKLatarbelakang:Sealerberbahandasar resin banyakdigunakankarenadapatmembentukretensimikro pada dentin.
