“…In ZnOE sealers, Eugenol is a potent anti-microbial agent and therefore, it may be attributable to the free eugenol released from the set materials [25,26]. Stevens et al, found that a final rinse with 95% ethanol increased the depth of penetration of a ZnOE based sealers and significantly reduced micro leakage [27]. Tests on dentinal tubule penetration have shown calcium hydroxide based sealers to be less effective in killing bacteria when compared to resin and eugenol based sealers [28,29].…”

Introduction: The purpose of this study was to evaluate the sealing ability of three different root canal sealers with and without amoxicillin, using a push-out bond strength test. Material and Methods:Sixty single-rooted extracted human teeth were used for this study. Each tooth was instrumented and irrigated with 5.25% Sodium hypochlorite (NaOCl) and 17% EDTA. The teeth were then divided into six test groups: Gutta percha (GP)/AH Plus (Dentsply, Germany), GP/AH Plus with 10% amoxicillin (TEVA Pharmaceuticals Sellersville, PA), GP/Pulp Canal Sealer EWT (Extended Working Time, SybronEndo Orange, CA), GP/Pulp Canal Sealer EWT with amoxicillin, GP/Apexit Plus, GP/Apexit Plus (Vivadent, Tulsa, US) with amoxicillin. After the sealer was set, the entire root was sectioned into 1 mm thick slices. A push-out bond strength test was performed by using a universal testing machine. The Student's t-test was used to compare the sealer bond strength within the specific sealer test groups and within each sealer at apical, middle and coronal root levels.Results: There was no significant difference between the groups within each sealer (p>0.05) with or without amoxicillin at the same root level. Conclusion:This study demonstrated that the addition of 10% by weight of amoxicillin does not significantly (p> 0.05) change the overall push-out bond strength of three endodontic sealers when compared at the apical, middle, and coronal tooth level.

“…It reduces the surface tension of liquids and sealants and, in addition, by evaporating from the tubules, it dries the dentin surface, which allows for better penetration of the sealant. The in vitro studies of Stevens et al [56] showed that a final rinse of 95% ethanol significantly improved penetration of the sealant and decreased leakage. Shafer [20] recommends applying 95% ethyl alcohol as the last rinse agent at a volume of 3 ml per canal to enable the sealant to penetrate better and consequently ensure a tight seal of the canal.…”

“…3,9,10 The application of ethanol to root walls has already been described in endodontic therapies for dehydrating root canals before filling them with sealer material. 8,11,12 Nonetheless, little evidence has described the relation between ethanol and bond strength to intraradicular dentin. 8 Furthermore, bond durability in dentin has been related to collagen matrix hydrolysis in hybrid layers.…”

Aim:The aim of this study was to evaluate the effect of chlorhexidine and ethanol application on the push-out bond strength and bond durability of fiber posts cemented with an etch-and-rinse adhesive system/resin cement to intraradicular dentin. Materials and methods:Fifty-four bovine roots were shaped for the cementation of a fiberglass post and received the application of 37% phosphoric acid. They were then randomly divided into three groups, according to the type of dentin treatment (n = 18) performed: no treatment (control group), 100% ethanol, or 2% chlorhexidine. Next, the adhesive system (Adper Scotch Bond Multipurpose Plus, 3M ESPE) was applied to the dentin, according to the manufacturer's instructions. Glass fiber posts were cemented with dual resin cement (Rely X ARC, 3M ESPE). After 48 hours, the specimens were serially sectioned for push-out test analysis, providing two slices from each root third (cervical, medium and apical), one of which was tested immediately and the other stored in distilled water for 180 days. The data were analyzed with three-way analysis of variance (ANOVA) for repeated measures and Tukey's test at a 5% significance level.Results: Intraradicular treatment with chlorhexidine yielded the highest bond strength means, followed by ethanol treatment. The control group presented the lowest bond strength means. Water storage exerted no effect on bond strength values. Conclusion:Both chlorhexidine and ethanol improved push-out bond strength to intraradicular dentin, with the former providing the best results, regardless of the storage time. Clinical significance: The application of 2% chlorhexidine or 100% ethanol may be an important step that can be taken to enhance bond strength of fiber posts to intraradicular dentin, when dual resin cements are used.
