“…In our review, storage period in water varied from 90 days 17 to 2 years 18 . A decrease in bond strength on sound dentin after ageing was detected in all included studies [17][18][19][20] . Conversely, the pooling of bond strength degradation data showed similar performance of etch-and-rinse and self-etch adhesives to sound dentin.…”

Objective: The purpose of this study was to analyze the effect of 2% chlorhexidine gluconate (CHX) on the degradation of composite resin-dentin bond strength when using self-etch adhesive systems.Methods: CHX (2%) was applied before application of two-step self-etch (TSC) and one-step self-etch (OSC) adhesive. Resin composite was applied incrementally. Specimens from the degradation treatment group were immersed in 10% NaOCl for 1 h. Shear bond strength was tested with a universal testing machine and analyzed using one-way ANOVA and Dunnett's T3 post-hoc test. The composite resin-dentin bonds were observed using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Results:In the treatment group without 10% NaOCl, shear bond strength values were higher in the 2% CHX-treated group (TSC 11.67±1.76 MPa and OSC 10.19±1.44 MPa) than in the untreated group (TSC 10.93±1.31MPa and OSC 9.97±1.41 MPa), although this difference was not statistically significant. In samples exposed to10% NaOCl, shear bond strength values were higher in the 2% CHX-treated group (TSC 11.14±1.22 MPa and OSC 9.95±1.21 MPa) than in the untreated group (TSC 10.08±0.45 MPa and OSC 8.62±0.85 MPa), although this difference was not statistically significant. The SEM of samples from the 2% CHX-treated group showed less degradation than samples from the untreated group did. Conclusion:Application of 2% CHX may decrease the degradation of the resin composite-dentin bond.

Effect of smear layer deproteinization on bonding of self-etch adhesives to dentin: a systematic review and meta-analysis

2018

ObjectivesThe aim of this systematic review was to critically analyze previously published studies of the effects of dentin surface pretreatment with deproteinizing agents on the bonding of self-etch (SE) adhesives to dentin. Additionally, a meta-analysis was conducted to quantify the effects of the above-mentioned surface pretreatment methods on the bonding of SE adhesives to dentin.Materials and MethodsAn electronic search was performed using the following databases: Scopus, PubMed and ScienceDirect. The online search was performed using the following keywords: ‘dentin’ or ‘hypochlorous acid’ or ‘sodium hypochlorite’ and ‘self-etch adhesive.’ The following categories were excluded during the assessment process: non-English articles, randomized clinical trials, case reports, animal studies, and review articles. The reviewed studies were subjected to meta-analysis to quantify the effect of the application time and concentration of sodium hypochlorite (NaOCl) and hypochlorous acid (HOCl) deproteinizing agents on bonding to dentin.ResultsOnly 9 laboratory studies fit the inclusion criteria of this systematic review. The results of the meta-analysis revealed that the pooled average microtensile bond strength values to dentin pre-treated with deproteinizing agents (15.71 MPa) was significantly lower than those of the non-treated control group (20.94 MPa).ConclusionsIn light of the currently available scientific evidence, dentin surface pretreatment with deproteinizing agents does not enhance the bonding of SE adhesives to dentin. The HOCl deproteinizing agent exhibited minimal adverse effects on bonding to dentin in comparison with NaOCl solutions.
