Nowadays, glass fiber post and composite resin cores have been used in endodontic treatment for esthetics achievement. The success of this treatment was affected by some factors such as bond strength between post and cores. The aim of this study is to investigate the effect of self etch bonding agent that use as adhesive materials between glass fiber post and resin composite by its bond strength. Totally twenty samples is used in this study, and divided in two groups (n=10 for each group), bonding group agents and without bonding agent group (control). The tensile-shear bond strength tested with Universal Testing Machine. Then, the bond strength values were analyzed statistically with t-test (p≤ 0,05). The result shows that bonds strength values in bonding agent groups were higher than without bonding agent groups. But, there is no significantly different between groups. In conclusion, bonding agent did not have effect on tensile-shear bond strength between glass fiber post and resin composite.

Background:Dentin bonding is an ever-evolving field in adhesive dentistry. With the introduction of newer systems into the market, there is a crucial need to test their efficiency in terms of bond strength. Dual-cured adhesives in theory may provide for a better degree of conversion as compared to conventional light-cured adhesives .Thus, the aim of this study was to compare the shear bond strength of three different self-etch adhesives namely ClearfilSE bond (Kuraray), Tetric N Bond Universal (IvoclarVivadent) and Futura Bond DC (Voco) to dentin. Materials & Methods: Ninety extracted non-carious, intact human mandibular molar teeth were selected for this study. Each tooth was decoronated using a double-sided diamond disc with water coolant to a depth of 2mm from the cusp tip .The cut dentin surface was then abraded against 600-grit wet silicon carbide papers for 60 seconds to produce a uniform smear layer. The root portion of each tooth was mounted on a plastic ring using cold cure acrylic resin. Specimens were then divided into three adhesive groups of 30 teeth each, Group A: ClearfilSE Bond (Kuraray), Group B: Tetric N Bond Universal (IvoclarVivadent), Group C :Futura Bond DC (Voco). All bonding agents were used according to the manufacturers’ instructions, in combination with the resin composite Tetric N Ceram (IvoclarVivadent). The samples were thermocycled, followed by shear bond strength testing using a Universal testing machine (Hounsfield). Data were subjected to statistical analysis using one-way analysis of variance (ANOVA) (P<0.05) and Post hoc Tukey’s test for inter- and intra- group analysis respectively. Results: Clearfil SE Bond yielded the highest shear bond strength values (30.9 ±4.66 MPa) which were statistically significant, followed byTetric N Bond Universal group (29.8 ±4.34) and the lowest shear bond strength values were recorded for Futura Bond DC (18.2 ±3.13). Conclusion: Clearfil SE bond and Tetric N bond Universal can be considered as better options than Futura Bond DC.

Abstract Background:In restorative dentistry we usually use Sandwich Technique for posterior restorations where GIC is placed below and a resin composite is placed over it. The bonding strength between these two materials are low. We are looking for the best adhesive system to put it in between. We think that the self-etching bond will give the best bonding strength between them whereas total etch will give lower bonding strength than self-etching system. Methods:ION-Z GIC was bonded to resin composite by using two different bonding agents. The thirty specimens used were prepared by using acrylic blocks with holes in each hole to retain the ION-Z GIC. The specimens were randomly divided into three groups:Group I: Control group.Group II: Total-etch adhesive was applied and cured over ION-Z GIC.Group III: Self-etch adhesive was applied and cured.The composite resin placed over the ION-Z GIC and cured. The shear bond strength was measured by shearing of the bonded specimens on Universal Testing Machine (Model 114) using speed of 0.1mm / minute. The reading was tabulated and subjected to statistical analysis using ANOVA and Tukey's test.Results:The test showed statistically significant difference between Group III and Group I and between Group III and Group II. Group III had the highest shear bonding strength.Conclusion:Self-etch adhesive agent produces have better shear bond strength to ION-Z than total-etch adhesive and to the group without any bonding agent.

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.

Introduction: Fissure sealants are one of the most proven ways to prevent tooth decay. These materials may remain on the tooth for a long time, and other areas of the tooth may decay. The purpose of this study was to present the best method for surface preparation a fissure sealant material (Icon) and composite restoration Materials and Methods: In this experimental laboratory study, 40 samples of composite restorative material were prepared in 4 groups of 10 discs of 6 mm in diameter and 2 mm in height. Total etch bonding agent was used in the first, second and third groups without surface preparation, with the use of drills and 37% phosphoric acid, and after drilling, respectively. In the fourth group, self-etch bonding agent was used after drilling. After that, Icon resin material was placed on the surface of the composite in a disc of 4 mm with height of 2mm in diameter and was cured. When the samples were thermocycled and incubated, their bonding strength was evaluated with Instron testing machine. Data were analyzed by one-way variance statistical ANOVA tests, Tukey test (p value < 0.05). Results: The mean value of bond strength of Icon to resin composite was significantly different among the 4 groups (p value < 0.05). The fourth group presented the greatest bond strength value while the third group had the lowest bond strength. Conclusion: When repairing fissure sealant, particularly Icon using resin composite, the best results of bond strength are achieved through surface roughening with drills and the application of self-etch bonding agents with a mild pH. Acidic etching agents (37% Phosphoric acid), however, have probably destructive effects on bond strength.

Objective: This study aimed to evaluate the effect of diode laser irradiation (970 nm) of a one-step self-etch adhesive (Clearfil S3Bond/CS3B) and of the bonding agent of a two-step self-etch adhesive (Clearfil Liner Bond F/CLBF) placed on dentin before polymerization on the shear bond strength.Material and methods: Forty sound premolars were sectioned buccally to obtain flat dentin surfaces. The specimens were divided into 4 groups (n=10): Group (OS) – CS3B + polymerization. Group (OS-L) – CS3B + laser + polymerization. Group (TS) – CLBF (bonding agent only) + polymerization. Group (TS-L) – CLBF (bonding agent only) + laser + polymerization. The diode laser was irradiated through an 8 mm bleaching tip for 10 seconds, (0.4 W, 10 Hz, 4 J). All samples were cemented to composite blocks submitted to 4000 thermal cycles. The samples were tested for shear bond strength in a universal testing machine. Data obtained was analyzed using Two-way (ANOVA) (P ≤ 0.05) and the Bonferroni post-hoc test. Representative samples from each group were analyzed using scanning electron microscopy (SEM). Results: GroupTS-L– (7.43 MPa) displayed statistically significant higher shear bond strength in comparison to that of group TS – (5.13 MPa). No statistically significant difference was found between group OS-L – (6.49 MPa) and group OS – (7.28 MPa). Group TS-L exhibited the highest resin penetration beyond the hybrid layer under SEM. Conclusions: Diode laser irradiation of a bonding agent placed on dentin without prior priming increased the bond strength to dentin and is promising as a new dentin adhesion protocol.

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.

Aim: To evaluate the effect of push-out bond strength between different surface treated glass fiber posts and resin composite. Materials and Methods: Four Cylindrical Glass fiber post (GFP) of 1.3mm diameter were divided into four groups depending on the surface treatment of glass GFP. Group I– no surface treatment done for GFP, group II - silane coupling agent was applied to GFP, then coated with bonding agent, group III – GFP was etched with 37% phosphoric acid, then treated with silane coupling agent and later coated with bonding agent and group IV - GFP was etched with 5% hydrofluoric acid then treated with silane coupling agent and later coated with bonding agent. The surface treated posts were vertically stabilized in the centre of a matrix. Composite was filled circumferentially and incrementally and photo cured. It was then sectioned perpendicular to the vertical axis yielding ten 1.0mm thick discs per fiber post. Ten specimens per group were obtained. They were subjected to push-out bond strength using universal testing machine. One - way analysis of variance and Tukey’s test were performed to verify statistical differences between groups (P< 0.01). Results: Superior bond strength was seen in 5% hydrofluoric acid etched group. Etching with 37% phosphoric acid or silane coupling agent alone did not show significant difference. GFP without surface treatment showed least bond strength. Conclusion: Glass fiber posts should be etched with 5% hydrofluoric acid and treated with silane coupling agent before applying bonding agent for a better bond strength between composite and the GFP. Keywords: Glass fiber post, push-out bond strength, custom made glass fiber post.
