Composite resin is a widely used aesthetic restoration. The restoration can fail due to secondary caries. Chlorhexidinegluconate 2% is used as a cavity disinfectant to eliminate microorganisms on the prepared cavity and to prevent thesecondary caries. The purpose of this study was to analyze the effect of chlorhexidine gluconate 2% to the bondstrength of composite resin with self etch system adhesive on dentine. Sixteen specimens of buccal dentine of premolarscrown are divided into 2 different groups. Group I: Clearfil SE Bond self-etch primer was applied for 20 seconds,Clearfil SE Bond bonding was applied for 5 seconds and polymerized for 10 seconds. Composite resin was constructedincrementally and polymerized for 20 seconds. Group II: prior to self etch primer application as in group I,chlorhexidine gluconate 2% was applied for 15 seconds. Shear bond strength was tested using Testing machine andanalyzed with unpaired T test. The highest shear bond strength was obtained by applying chlorhexidine gluconate 2%.The study concludes that chlorhexidine gluconate 2% application to dentine did not affect significantly to the bondstrength composite resin using self etch adhesive systems.

In this laboratory study shear bond strengths of three filled and one unfilled adhesive systems to enamel and dentine were compared. Forty-eight extracted intact noncarious human mandibular molars were randomly assigned to two groups of 24 one for bonding to enamel and the other for bonding to dentine. Buccal and lingual surfaces of each tooth were randomly assigned for application of each one of filled (Prime & Bond NT (PBNT), Optibond Solo Plus (OBSP), and Clearfil SE Bond (CSEB)) and unfilled (Single Bond (SB)) adhesive systems (n=12). A universal resin composite was placed into the translucent plastic cylinders (3 mm in diameter and 2 mm in length) and seated against the enamel and dentine surfaces and polymerized for 40 seconds. Shear bond strength was determined using a universal testing machine, and the results were statistically analyzed using two-way ANOVA, one-way ANOVA,t-test, and Tukey HSD post hoc test with a 5% level of significance.There were no statistically significant differences in bond strength between the adhesive systems in enamel, but CSEB and SB exhibited significantly higher and lower bond strength to dentine, respectively, than the other tested adhesive systems while there were no statistically significant differences between PBNT and OBSP.

Abstract Objective Bonding to different dentin substrates influences resin composite restoration outcomes. This study investigated the influence of different adhesion protocols on the shear bond strength of universal adhesive systems to sound and artificial caries-affected dentin (CAD). Materials and Methods Occlusal enamel of 80 premolars were wet grinded to obtain flat midcoronal dentin. Specimens were equally divided according to the substrate condition: sound and CAD by subjecting to pH-cycling for 14 days. Each dentin substrate was bonded with the adhesive systems used in this study: Single Bond universal adhesive or Prime&Bond universal (applied either in etch-and-rinse or self-etch adhesion protocol). Adhesive systems were utilized according to manufacturers’ instructions, then resin composite was built up. Specimens were tested for shear bond strength. The data were analyzed by three-way analysis of variance, and failure modes were determined using stereomicroscope. Results There was no statistically significant difference between the two tested adhesive systems on artificially created CAD with different adhesion protocols. On sound dentin, Single Bond universal, either in the etch-and-rinse or self-etch adhesion protocols, revealed higher statistically significant shear bond strength mean values compared with CAD. Conclusion Single Bond universal adhesive in an etch-and-rinse adhesion protocol improved only bonding to sound dentin, while no added positive effect for the etching step with Prime&Bond universal adhesive was found when bonded to both sound and CAD substrates. The influence of CAD on the performance of the universal adhesives was material-dependent.

ABSTRACT Background The purpose of this study was to evaluate the shear bond strength (SBS) of two different adhesives to normal and deproteinized dentin at an interval of 24 hours and 6 months. Materials and Methods Sixty human molars were sectioned and embedded in acrylic resin. Enamel was worn out and dentin was exposed over which acid etching was performed and the specimens were divided into 12 groups (n = 10) depending on the adhesive system used, the dentin treatment performed and the length of evaluation. A resin composite was inserted over the prepared area followed by assessment for shear bond strength evaluation. Results The application of Sodium hypochlorite (NaOCl) significantly increased the SBS values of prime and bond NT but for adper single bond it was decreased. The means values of SBS standard deviation (SD) in MPa for adhesive systems with 5% NaOCI for 60 seconds, 120 seconds and without NaOCl treatment were: prime and bond NT = 12.48 (1.25), 13.01 (1.00) and 17.74 (4.26) and for adper single bond = 10.92 (1.65), 10.96 (2.45) and 7.57 (1.45). Shear bond strength after storage time of 6 months was decreased significantly. Conclusion According to the statistical analysis, the results only partly supported the hypotheses and greatly depend on the composition of adhesive system.

Objective: To assess the shear bond strength (SBS) of resin composite to deep dentin, using 1 and 2.5% chitosan pretreatment as well as different adhesive systems. Material and Methods: 80 human maxillary molars were randomly divided to eight groups according to the type of adhesive system and dentin pretreatment (n = 10): I) two-step self-etch system (Clearfil SE bond); II) two-step etch-andrinse system (Adper single bond 2); III) 2.5% chitosan + Clearfil SE bond; IV) 2.5% chitosan +etch + Adper single bond 2; V) etch + 2.5% chitosan + Adper single bond 2; VI) 1% chitosan + Clearfil SE bond; VII) 1% chitosan + etch + Adper single bond 2; VIII) etch + 1% chitosan + Adper single bond 2 (chitosan solution (w/v): 2.5 g and 1 g of chitosan (Sigma Aldrich, USA) was dissolved in 100 ml of 1% acetic acid). Plastic molds were positioned on dentin and filled with composite (Z350, 3M ESPE, USA). SBS (MPa) was tested using a universal testing machine. ANOVA tests, Tukey’s test, and independent t test were used to analyze data (p < 0.05). Results: The highest SBS value among self-etch groups was observed with 1% chitosan (p = 0.001). In the etch-and-rinse group, the SBS of 1% chitosan was significantly lower than the other groups. Chitosan treatment following acid etching led to higher SBS in comparison to when chitosan was applied before etching, with the significant difference in 1% concentration (p = 0.030). A predominance of mix fractures was observed in dentin. Conclusion: Improved dentin bond strength can be achieved through immediate dentin pretreatment with 1% chitosan in self-etch adhesive systems. Chitosan Pretreatment may not be advantageous for etch-and-rinse adhesive systems. Keywords Adhesive system; Chitosan; Deep dentin; Shear strength.
