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.

The aims of this study were to evaluate the shear bond strength (SBS) of four adhesive systems applied to primary dentin and enamel and verify, after SBS testing, the failure mode of the adhesive interface. Sixty extracted sound primary molars were selected and crowns were sectioned in a mesial-distal direction. Specimens were randomly assigned into two groups (adhesion to enamel and adhesion to dentin) and then subdivided into four subgroups according to the adhesive system (n=15): Scotchbond Multi-Purpose (SMP) – Single Bond (SB) – Clearfil SE Bond (and Adper Prompt LPop (APL) – SBS tests were performed and the obtained values were statistically analyzed using ANOVA and Tukey tests (p&lt;0.05). The failure mode analysis was performed with a Scanning Electron Microscope (XL-30, Philips). SBS mean values on enamel were [MPa (SD)]: SMP – 27.89 (7.49); SB – 23.92 (8.8); CSB – 24.36 (6.69); APL – 25.96 (4.08); and on dentin: SMP – 17.29 (4.25); SB – 18.2 (8.74); CSB – 16.13 (7.14); APL – 6.04 (3.35). The predominant failure mode was cohesive (primarily of the bonding agent). On enamel SBS was statistically similar for all four adhesives. On dentin SBS of APL was lower than the other tested adhesives.

ABSTRACT Aim This in vitro study evaluated the effect of different cavity disinfection agents on bond strength of a silorane-based resin composite. Materials and methods Thirty-six caries-free human third mandibular molars sectioned in mesio-distal direction were mounted in acrylic resin with their flat dentin surfaces exposed. After the dentin surfaces were wet ground with # 600 silicon carbide paper, the teeth were randomly divided into 6 groups of 12 each according to the cavity disinfection agents; chlorhexidine (CHX); sodium hypochlorite (NaOCl), propolis, ozone, Er, Cr:YSGG laser and no treatment (control). After treatment of dentin surfaces with one of these cavity disinfection agents, Filtek Silorane adhesive system was applied. The silorane-based resin composite, Filtek Silorane was condensed into a mold and polymerized. After storage at 37°C for 24 hours, the specimens were tested in shear mode at a crosshead speed of 1.0 mm/minute. The results were analyzed by one-way ANOVA. Results No statistically significant difference was observed between the groups (p>0.05). Conclusion The use of the tested cavity disinfection agents, chlorhexidine, sodium hypochlorite, propolis, ozone and Er, Cr:YSGG laser did not significantly affect the dentin bond strength of a silorane-based resin composite, Filtek Silorane. Clinical significance Cavity disinfectant applications did not affect the dentin bond strength of a silorane-based resin composite.

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.

Microshear Bond Strength

The aim of this study was to evaluate the effect of 2% chlorhexidine (CHX) application during the bonding protocol on microshear bond strength of two adhesive systems, after storage in different media. Seventy-two human molars had their crowns cut in half and embedded in PVC cylinders with acrylic resin. The specimens were randomly divided into experimental groups (n=12) according to the adhesive system (Ambar and Single Bond 2), use of CHX in the bonding protocol, and time interval (24 h and 15 days) in the storage media (distilled water, mineral oil and 1% sodium hypochlorite - NaOCl). Adhesive systems were applied in accordance to manufacturers' recommendations, with or without the use of CHX, and resin composite (Z350 XT) cylinders were placed on the hybridized dentin. After photoactivation, the specimens were stored in distilled water, mineral oil and 1% NaOCl for 24 h and 15 days. Microshear bond strength was determined at a crosshead speed of 0.5 mm/min until fracture. The bond strength data were analyzed statistically by 4-way ANOVA and Tukey's test (α=5%). Use of CHX in the bonding protocol did not cause loss of bond strength in any of the evaluated situations, irrespective of time and storage medium. The storage medium had no influence on bond strength values after 15 days when the bond protocol without CHX application was used. However, the use of CHX in the protocol influenced negatively the bond strength values for Single Bond 2 after 15 days storage in distilled water and 1% NaOCl.

The aim of this study was to assess the shear bond strength of four acetone-based one-bottle adhesive systems to enamel and dentin, and compare to that of an ethanol-based system used as control. Fifty human molars were bisected mesiodistally and the buccal and lingual surfaces were embedded in acrylic resin using PVC cylinders. The buccal surfaces were ground to obtain flat dentin surfaces, while the lingual surfaces were ground to obtain flat enamel surfaces. All specimens were polished up to 600-grit sandpapers and randomly assigned to 5 groups (n=20; 10 dentin specimens and 10 enamel specimens), according to the adhesive system used: One-Step (Bisco); Gluma One Bond (Heraeus Kulzer); Solobond M (Voco); TenureQuik w/F (Den-Mat) and OptiBond Solo Plus (Kerr) (control). Each adhesive system was applied according to the manufacturers' instructions. The respective proprietary hybrid composite was applied in a gelatin capsule (d=4.3mm) and light-cured for 40 s. The specimens were tested in shear strength with an Instron machine at a crosshead speed of 5 mm/min. Bond strengths means were analyzed statistically by one-way ANOVA and Duncan's post-hoc (p£0.05). Shear bond strength means (MPa) (±SD) to enamel and dentin were: Enamel: One-Step=11.3(±4.9); Gluma One Bond=16.3(±10.1); Solobond M=18.9(±4.5); TenureQuik w/F=18.7(±4.5) and OptiBond Solo Plus=16.4(±3.9); Dentin: One-Step=6.4(±2.8); Gluma One Bond=3.0(±3.4); Solobond M=10.6(±4.9); TenureQuik w/F=7.8(±3.9) and OptiBond Solo Plus=15.1(±8.9). In enamel, the adhesive systems had statistically similar bond strengths to each other (p>0.05). However, the ethanol-based system (OptiBond Solo Plus) showed significantly higher bond strength to dentin than the acetone-based systems (p£0.0001). In conclusion, the solvent type (acetone or ethanol) had no influence on enamel bond strength, but had great influence on dentin bonding, which should be taken into account when choosing the adhesive system.

Bleaching Treatment

In this bond strength study, a bleaching agent containing 10% carbamide peroxide was applied over composite-teeth bonded interfaces of two adhesive systems applied to enamel and dentin. Sixteen human third molars were used for bonding procedures. Single Bond (SB) and Clearfil SE Bond (CB) were applied to enamel and dentin according to the manufacturers' instructions. A resin composite cube-like structure was incrementally built on the bonded surfaces. The restored teeth were sectioned into 0.7 mm thick slices that were trimmed at enamel or dentin bonded interfaces to an hourglass shape with a cross-sectional area of approximately 0.5 mm². Specimens were assigned to 8 groups (n = 10) according to the following factors under study: dental substrate (enamel and dentin); adhesive system (SB and CB) and treatment (10% carbamide peroxide and not bleached/control). The bleaching gel (Opalescence) was applied at the bonded interfaces for 6 hours during 14 days and after daily treatment specimens were stored in artificial saliva. Unbleached specimens were stored in artificial saliva for 14 days. Specimens were tested for tension and the data were analyzed by three-way ANOVA and Tukey's test (p < 0.05). Enamel tensile bond strength of CB was reduced after carbamide peroxide application. The bleaching treatment did not alter dentin bond strength of both adhesives. The results suggest that bleaching significantly affects bond strength of CB to enamel, but no influence on bond strength to dentin was noted for both adhesive systems.

ABSTRACT Purpose The objective of this study was to evaluate the influence of the Grander technology on the shear bond strength of total-etch adhesive system Single Bond 2 to dentin. Materials and methods Forty bovine incisors were used. They were sectioned and the buccal surfaces worn down with abrasive paper. Acid etching was performed, and the specimens were divided into two groups (n = 20): Group G1—Single Bond 2 adhesive system (3M ESPE) under normal conditions; group G2—Single Bond 2 adhesive system modified by physical contact for 48 hours with the flexible unit Grander system. The resin composite was inserted with the aid of a metallic matrix over the prepared area. After the mechanical shear test, data were submitted to the statistical t-test (5%). The t-test showed that the results for G1 and G2 were similar (p > 0.05). The mean values (± SD) were: G1—6.66 (± 2.40); G2—5.26 (± 2.15). Conclusion Grander technology did not influence the initial shear bond strength of the Single Bond 2 adhesive system to dentin.

ABSTRACT Aim This in vitro study evaluated the shear bond strength of a chemical resin cement to five adhesive systems in bovine dentin. Materials and methods One hundred and three bovine teeth were divided into five experimental groups (n = 19) and two control groups (n = 4). A flat dentin surface was exposed on each tooth after wet grinding the buccal enamel, in order to apply the adhesive systems (Adper Single Bond, Adper Scotchbond Multi-Purpose, Multi Bond Uno plus Duo, One Step, Prompt L-Pop) to 95 teeth, according to manufacture's instructions. Four teeth were etched with phosphoric acid (negative control) and four teeth were no etched with phosphoric acid (positive control). Light-cured composite blocks were sandblasted before the cementation with C&B Cement (Bisco) over the treated dentin. The specimens were stored in distilled water at 37°C and submitted to the shear bond strength test after 7 days. Results ANOVA and Tukey tests (p = 0.05) demonstrated that Adper Single Bond (7.47 ± 4.37), Adper Scotchbond Multi-Purpose (6.68 ± 5.11) and One Step (7.30 ± 4.29) presented the highest bond strength values. Prompt L-Pop (0.05 ± 0.17) and Multi Bond Uno plus Duo (0.72 ± 1.41) presented the lowest significant bond strength values. Conclusion The shear bond strength of composite resin cylinders cemented with chemically activated resin cement depends on the adhesive system used. Clinical significance Fourth and fifth generation light polymerized bonding systems are indicated when self-polymerizing cements are used.
