Investigation of the Effect of Sodium Hypochlorite, EDTA, Propolis, Boric Acid and Citric Acid Irrigation Solutions on Push-out Bond Strengths of Root Canal Sealers

Objective:The aim of this study is to investigate the effect of different root canal irrigation solutions, including propolis and boric acid (BA), on the bonding strengths of epoxy-resin-based AH Plus and bioceramic-based Bioserra root canal sealers on root dentin. Methods:One hundred extracted teeth with single root-single canal were shaped and divided into 2 groups according to filling material (AH Plus and Bioserra) and each group was divided into 5 subgroups according to irrigation solution (5.25% NaOCl, 17% EDTA, 10% citric acid, 10% BA, 10% propolis).The teeth of which canals were filled were incubated at 37 °C for one week, then embedded in acrylic resin.Horizontal sections with thickness of 2 mm were taken from the middle level of the root of each tooth and pressing force was applied in vertical direction until a break occurred in the connection, POBS (push-out bond strength) values were calculated.Statistical analysis was performed using Kruskal-Wallis H and Mann-Whitney U tests.Finally samples were examined with binocular microscope.Results: Regardless of the sealer used, mean POBS values of 5.25% NaOCl solution groups were found significantly higher than others (p<0.05).Also regardless of the irrigation solution used, mean POBS values of AH Plus groups were significantly higher than Bioserra groups (p<0.05).Among the experimental groups that ÖZ Amaç: Bu çalışmanın amacı, propolis ve borik asit (BA) dahil olmak üzere farklı kanal yıkama solüsyonlarının epoksi-rezin bazlı AH Plus ve biyoseramik bazlı Bioserra kanal patlarının kök dentini üzerindeki bağlanma dayanımlarına etkisini araştırmaktır.Yöntemler: Tek kök-tek kanallı 100 adet çekilmiş insan dişi döner aletle şekillendirildikten sonra kanal dolum malzemesine (AH Plus ve Bioserra) göre 2 gruba ayrılmış ve her grup yıkama solüsyonuna (%5,25 NaOCl, %17 EDTA, %10 sitrik asit, %10 BA, %10 propolis) göre 10 örnek içeren 5 alt gruba ayrılmıştır.
