“…Although the results of this study showed no significant effect of NaOCl on the strength of bond materials, other studies have shown that NaOCl has a negative effect on the bond strength due to the oxidation of dentin components and formation of reactive free radicals, which results in the inhibition of adhesive polymerization and decrease in the bond strength (10). In Abo-Hamar's study, NaOCl significantly increased the excite bond strength (7).…”

“…Chlorhexidine was used for a short time and at a high concentration (2% versus 0.12%), and self-etch adhesive systems were applied in these studies (22). In another study, CHX significantly reduced the bond strength of total-etch adhesive systems (10). Some studies showed that the bond strength of CHX irrigated dentin with a total-etch system was improved, which was attributed to the inhibition of matrix metalloproteinases -2, -8, and -9, which are collagen-degrading enzymes (21,25,26).…”

“…Moist cotton pellet Ethanol cotton pellet Round bur hypothesis (10). The results of the CHX effect on the bond strength of adhesive resins to dentin are contradictory (10,21,22). Some studies have claimed that CHX has no effect on the interactions of resin systems with dentin due to its non-oxidizing nature (23,24).…”

“…Some studies have suggested a one-week delay in bonding after endodontic treatment to eliminate the negative effects of irritants. However, this delay time is not always possible in clinical conditions, and sometimes the tooth should be repaired immediately after endodontic treatment (10).…”

Background: Chemical substances used to prepare root canals and their residuals can alter dentin surface composition, affecting restorative systems bonding to dentin. Objectives: This ex vivo study evaluated the effects of different sealer removal methods on the micro-tensile bond strength of dentin surfaces exposed using endodontic irrigants. Methods: A total of 45 extracted healthy mandibular molars were sliced from the occlusal surface to expose their dentin surface and were randomly divided into three main groups (n = 15) based on the irrigants as G1: Distilled water (control), G2: Sodium hypochlorite (NaOCL) 5.25%, and G3: Chlorhexidine (CHX) 2%. AH Plus endodontic sealer, was applied to all exposed dentin surfaces. Each group was divided into four subgroups (SG) according to the sealer removal methods: SG1: No root canal sealer (control), SG2: Moist cotton pellet, SG3: Ethanol 95% saturated cotton pellet, SG4: Round diamond bur. The teeth were restored using single bond plus and Z250 composite and sectioned to prepare sticks for micro-tensile bond testing. Additionally, failure patterns were investigated. Comparison between experimental groups was performed using Kruskal-Wallis H and Dunn's post-hoc tests. The accepted significance level for all tests was P < 0.05. Results: A significant decrease was observed in the micro-tensile bond strength of the control group cleaned with 95% Ethanol saturated cotton pellets. In addition, the highest micro-tensile bond strength was observed in dentin cleaned through a diamond round bur and in the group irrigated with CHX. The failure modes were mainly adhesive. Conclusions: Within this study's limitations, the dentin bond strength is affected by the irrigation protocol and sealer removal method.

This study aims to analyze and assess the effects of three particular dentin pretreatment solutions on the bond durability of a two-step self-etch adhesive (Optibond XTR) applied to dentin after ageing for 2 years. Thirty-five third molars which were extracted (n = 5 for μTBS, n = 2 for nanoleakage) were divided into five groups: Group 1:Control (no pretreatment), Group 2:17% EDTA, Group 3:2% CHX, Group 4:17% EDTA plus 2% CHX, Group 5: Q-Mix. After the pretreatments of dentin, the dentin adhesive was applied as per the guidelines provided by the manufacturer. Half of the specimens were subjected to μTBS tests for 24 hr, while the remaining half were subjected to the tests after being kept for 2 years in water storage. Also, nanoleakage was evaluated with FE-SEM by examining silver nitrate deposits. The data obtained were evaluated using a two-way analysis of variance and Tukey Post Hoc test. The dentin pretreatments did not affect the 24 hr and 2 years μTBS values for OptiBond XTR. At 24 hr, the EDTA + CHX group (50.3 ± 4.9) showed that the highest μTBS value was obtained. Water ageing significantly reduced the μTBS results and after 2 years the highest μTBS value was obtained from the Q-Mix group (37.7 ± 5.2). Different dentin pretreatments do not alter the 24-hr μTBS and were not able to preserve the bond strength after 2 years of ageing. Q-Mix was able to slow down the regression in the strength of the dentin bond as well as nanoleakage over time.
