Restoration is a treatment to restore the structure of missing dental hard tissue due to caries. Flowable composite has good adaptability to the cavity wall so that it is widely used as an intermediate layer. Composite resins require an adhesive system to bond chemically with dental hard tissue. Self - adhering flowable composite combining etching, priming, and adhesive in one flowable package. This study was conducted with the aim to determine the difference in shear bond strength between Self – adhering flowable composite and flowable composite with self – etch adhesive system on dentine. The number of samples used was 38 pieces. After dentin was prepared and fixed, samples was divided into 2 groups, each group consisting of 19 samples. First group was applied with self – adhering flowable composite, second group was applied with flowable composite with self – etch adhesive system. Samples was immersed in pH 6.8 normal saline and stored for 24 hours, then dried and shear bond strength was tested using a universal testing machine. The data obtained were analyzed using independent t – test. The statistical analysis using independent t – test showed that there were significant differences in the shear bond strength between the two groups, p=0,000 (p<0.05). The study concluded that there is difference of shear bond strength between self – adhering flowable composite and flowable composite with self – etch adhesive system on dentine.

ABSTRACTObjective: The shear bond strength of adhesives applied to dentin was investigated after irradiation with an erbium-doped yttrium aluminum garnet (Er:YAG) laser.Methods: Superficial and deep dentin specimens from human molars were treated either with carbide bur or an Er:YAG laser. Two etch and rinse adhesives (Single Bond and XP Bond) and two self-etch adhesives (Prompt L-Pop and Xeno III) were employed to bond the composite. Shear bond strength (SBS) was determined after storage in water for 24 h using a universal testing machine with a crosshead speed of 0.5 mm/min. Failure patterns and modes were analyzed and evaluated using a stereomicroscope. In addition, samples were processed for Scanning Electron Microscopy SEM evaluation. A linear mixed model was used, and pairwise comparisons were made using the Bonferroni test.Results: Results showed significant differences between the levels of dentin treatment (p=.01) in carbide bur-cut dentin and lased dentin, as well as significant interaction effects due to the depth of dentin and the bonding system used. The etch and rinse adhesives bonded less effectively with lased dentin than with carbide bur-cut dentin, while self-etch adhesives bonded equally well with lased and bur-cut superficial dentin but much less effectively with lased deep dentin than with bur-cut deep dentin. SEM revealed a predominantly adhesive failure mode in laser-ablated fractured specimens, while a mixed failure mode was apparent in the bur-cut fractured specimens.Conclusions: Cavities prepared by laser seem less receptive to adhesive procedures than conventional bur-cut cavities.

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.

Aim: Repairing amalgam restorations with composite resins is a clinical practice with many advantages. An effective adhesion is achieved between amalgam and composite by applied different surface treatment on amalgam surface. In this study, the effect of adhesive systems applied on amalgam surface on composite-amalgam connection was investigated. Methodology: Standard cavities were opened in 70 acrylic molds that had completed their polymerization and amalgams were placed in these cavities. Seven groups were randomly assigned to different surface treatments on amalgam. In group 1 only roughening with diamond bur , in group 2 acid etch, in group 3 acid application after roughening with diamond bur, in group 4 roughening with diamond bur and silane, in group 5 acid etch and silane, in group 6 roughening with diamond bur and Alloy Primer and finally 7. acid etch and Alloy Primer was applied in the samples. After the application of clearfil universal bond to all groups, composite resins were placed and polymerized. Shear bond strengths were tested with a Universal testing machine. Obtained data were evaluated by one way ANOVA and Tukey B tests. Results: In the statistical evaluation of the groups, the highest shear bond strength between amalgam-composite was seen in the 3rd group where both roughening with diamond bur and acid were applied together, and the lowest shear bond strength was seen in the first group with only roughening with diamond bur. The differences between the groups were statistically significant (p <0.05). Conclusion: The roughening of the amalgam surface affects the shear bond strength between amalgam and composite resin. These results obtained in vitro conditions should be supported with clinical studies.   How to cite this article: Cangül S, Adıgüzel Ö, Erpaçal B, Ünal M, Acartürk M, Satıcı Ö.

ABSTRACTObjectives: The aim of this study was to compare the shear bond strength of several self-etch adhesives to their two-step predecessors to ground and unground enamel.Methods: Seventy-five extracted, non-carious human third molar teeth were selected for this study. The buccal surfaces of each tooth were mechanically ground to obtain flat enamel surfaces (ground enamel), while the lingual surfaces were left intact (unground enamel). The teeth were randomly divided into five groups according to the adhesive systems (n=15): one-step self-etch adhesive - Clearfil S3 Bond, its two-step predecessor - Clearfil SE Bond, one-step self-etch adhesive - AdheSE One, and its two-step predecessor - AdheSE, and a two-step etch-and-rinse adhesive - Adper Single Bond 2(control). After application of the adhesives to the buccal and lingual enamel surfaces of each tooth, a cylindrical capsule filled with a hybrid composite resin (TPH) was seated against the surfaces. The specimens were stored in distilled water at 37°C for 24 hours, followed by thermocycling (5°C-55°C/500 cycles). They were subjected to shear bond strength test in a universal testing machine at a crosshead speed of 1.0 mm/minute. The data were compared using a two-way ANOVA, followed by Bonferroni test at P<.05Results: All adhesives exhibited statistically similar bond strengths to ground and unground enamel except for the etch-and-rinse adhesive that showed significantly higher bond strengths than the self-etch adhesives (P<.05). No significant differences in bond strength values were observed between ground and unground enamel for any of the adhesives tested (P=.17).Conclusions:Similar bond strengths to ground and unground enamel were achieved with one-step self-etch adhesives and their predecessors. Enamel preparation did not influence the bonding performance of the adhesives tested. (Eur J Dent 2012;6:280-286)

Blood–saliva contamination negatively affects the bonding potential of adhesive agents. The study aimed to assess the effect of various cleaning protocols on micro-shear bond strength (μSBS) between blood–saliva-contaminated post-etched dentin and composite resin in total-etch and self-etch adhesives. The cleaning methods tested were water rinsing, 37.5% phosphoric acid (H3PO4) re-etching, 6% sodium hypochlorite (NaoCl), 2% chlorhexidine gluconate (CXG), isopropyl alcohol (IPA), and pumice. Nono-hybrid composite cylinders with a 3-mm diameter and 2-mm height were directly cured over the dentin substrate, stored for 24 h, and subjected to 12,000 thermocycles. The shear force was exerted with a 200-μm knife-edged chisel-shaped head from a universal testing machine. The type of failure was assessed with stereomicroscope magnified images. The obtained data were evaluated by Kruskal–Wallis and Mann–Whitney U post-hoc tests. Water-rinsed contaminated dentin surfaces showed substantially reduced μSBS in the total etch from 25.93 to 20.29 Mpa and the corresponding values for the one-step self-etch adhesive were 10.10 to 8.8. Re-etching with 37.5% H3Po4 resulted in a recovery of bonding potential in both total-etch (24.58 Mpa) and self-etch adhesive (9.23 Mpa). Alternately, NaoCl and pumice cleaning showed promising results for the total-etch (23.51 Mpa) and self-etch (7.79 Mpa).

Abstract Introduction: Light cured composite resins have become the method of choice in orthodontic bonding procedures worldwide. In recent years, a new primerless orthodontic bonding composite, Heloisit with good bond strength, fluoride release and an advantage of not requiring use of a primer has been introduced. Aims: To compare the bonding characteristics of commonly available self and light cured adhesives with primerless system. Materials and Methods: One hundred twenty extracted human premolar teeth were mounted on similar sized aluminium blocks and were divided into four groups of thirty teeth each. All teeth were bonded with four different bonding systems Group i) Light Cured Primerless orthodontic Composite (Heliosit®, Ivoclar Vivadent, Schaan, Liechtenstein), Group ii) Light Cured Composite Resin (Transbond XT®, 3M Unitek), Group iii) Light Cured GIC (GC Fuji Ortho LC®, GC Corp.), Group iv) Self Cured Composite Resin (Rely-A-Bond®, Reliance, Inc., Illinois, USA) using metallic premolar first premolar brackets (0.022” Ortho Organizers). These were evaluated for shear bond strength using an Instron testing machine. Surface characteristics after debonding were studied under scanning electron microscopy (SEM) and evaluated using the adhesive remnant index (AR Index). Results: Shear bond strength (SBS) of primerless orthodontic light cured Heliosit® composite was clinically significant and adequate for clinical use. It lies intermediate to Transbond XT light-cured composite and Light Cured GIC. The least bond strength was shown by Rely-a-Bond® self-cured composite resin. Conclusions: Heliosit® light cured primerless orthodontic composite can be used for everyday clinical use due to its ideal characteristics of sufficient bond strength and reduced chances of enamel damage at debonding. Additionally, it is primerless and saves valuable clinical time.

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.
