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.

The revolution in orthodontics has been due to replacement of cemented bands by orthodontic brackets. Acid etching is required to bond a bracket on tooth’s surface. Traditional three step acid etch procedure consisted of etching, sealing/priming and bonding. The self etch system (etchant and primer together) can be used without the need for surface preparation, saving chair side time and minimizing contamination. Objectives: To compare the shear bond strength (SBS) of orthodontic bracket bonded with Conventional etching primer (Transbond XT, 3M Unitek) with self etch primer (Adper Prompt L-Pop, 3M ESPE). Study Design: Prospective study Setting: Orthodontic Clinic of Ihsan Mumtaz Hospital, Lahore and PCSIR (Lahore). Period: 6 months from June 2018 to December 2018. Material and Methods: 60 human maxillary premolars were randomly divided into 2 groups of 30 each. Group-I was bonded with conventional etching primer + composite and Group-II was bonded with self etch primer + composite. Shear bond strength was measured through Ionstron force testing machine. Statistical Analysis: For each variable, shear bond strength, arithmetic mean, standard deviation, minimum and maximum values were calculated. t-test was used to compare the shear bond strength (SBS) of the two groups and P value less than and equal to 0.05 was considered significant. Results: The mean shear bond strength in group 1 and group II was10.5MPa and 7.36MPa respectively. Conclusion: The shear bond strength of Conventional etching primer + adhesive was significantly higher than the shear bond strength of self etch primer +adhesive group.

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 Objectives To evaluate and compare enamel shear bond strength of an all-in-one self-etching primer (Prompt™ L-Pop™) to regular acid etch material when bonded to two-fissure sealant systems (Concise and Dyract Seal). Method and Materials Forty newly extracted non-carious first permanent molars were embedded in a Teflon mold. The teeth were divided into four groups and each consisted of ten specimens. The bonding surfaces were treated with either Prompt L-Pop as recommended by the manufacturer or etched with phosphoric acid. After 24 hours of water storage, the specimens were evaluated for shear bond strength using an Instron testing machine. Scanning electron microscope (SEM) examinations were carried out to evaluate the failure sites of the sealants. Results The mean shear bond strengths using Prompt L-Pop were Concise: 23.46 MPa and Dyract Seal: 20.34 MPa. These values were higher than and statistically different from those of Dyract Seal (9.99 MPa) and Concise (8.85 MPa) when phosphoric acid was used. The failure was predominantly of the adhesive type. The SEM examination showed the failure of debonding was predominantly related to the type of etching systems used rather than the type of fissure sealants. Conclusion The use of the all-in-one self-etching adhesive Prompt L-Pop improves the mean enamel shear bond strength of fissure sealants. Citation Al-Sarheed MA.

The aim of the present study was to evaluate the influence of gingival retraction agents and different bonding regimes on the shear bond strength (SBS) of dentin to resin composite. Sixty human teeth were divided into six groups (n = 10) based different combinations of hemostatic agents (Viscostat and Expasyl) and dentin bonding regimes [Total-etch (TE) and self-etch (SE)]. Group A1, Expasyl and TE; group A2: Expasyl and SE; group B1: Viscostat and TE; group B2: Viscostat and SE, group C1 (control): No hemostatic agent and TE; group C2 (control): No hemostatic agent and SE. Composite build-ups (Tetric N Ceram) were performed after dentin treatments and SBS was assessed using universal testing machine. Failure analysis was performed with a stereomicroscope and classified as adhesive, cohesive and admixed. Data was analysed using ANOVA and multiple comparisons test. The maximum and minimum SBS was displayed by specimens in group C1 (36 59 ± 5 94 MPa) and group B2 (17 95 ± 2 52 MPa) respectively. Control groups (C1 and C2) showed statistically comparable SBS, which was significantly higher in comparison to experimental groups (A1, A2, B1, and B2) (p < 0.05). Hemostatic agents inhibited the adhesive bond strength of composite to tooth dentin. Reversal effect of total-etch and self-etch bonding regimes on hemostatic agent treated dentin SBS was minimal.

Objectives: Achieving durable restorations with adequate strength in severely damaged primary anterior teeth in children is a priority. The aim of this study was to investigate the effect of dentin pretreatment with chlorhexidine on push-out bond strength of composite restorations. Materials and Methods: In this in vitro experimental study, 56 extracted primary anterior teeth were randomly divided into 4 groups: (1) saline and total-etch bonding agent, (2) chlorhexidine and total-etch bonding agent, (3) saline and self-etch bonding agent, and (4) chlorhexidine and self-etch bonding agent. After the application of bonding agents, the post space was filled with Z250 composite resin. Following thermocycling of the samples, the push-out test was performed using a universal testing machine, and the results were analyzed with two-way ANOVA. Results: The mean push-out bond strength values in groups 1 to 4 were 5.7, 8.39, 5.35, and 7 MPa, respectively. Chlorhexidine groups had significant differences with saline groups in bond strength (P<0.05) but there was no statistically significant difference between the self-etch and total-etch bonding agents in the groups (P>0.05). Conclusion: Both types of bonding agents (self-etch and total-etch) exhibited favorable results in radicular dentin of primary anterior teeth; however, pre-treatment with chlorhexidine increased the push-out bond strength of composite restorations in primary anterior teeth.

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.

Abstract Introduction: The management of dentinal hypersensitivity involves remineralization by various means, one of which being CPP-ACP paste, followed by restoration. It was speculated that the bond strength of self-etching adhesive was affected following the application of CPP-ACP paste and prior etching with phosphoric acid. Aims and objectives: To evaluate the tensile bond strength (TBS) of G-Bond (GB, self-etching adhesive) to dentin following the application of CPP-ACP (Tooth Mousse/TM), with and without prior etching. Materials and method: Freshly extracted forty five permanent molars were collected for the study. All the teeth were ground and polished to expose the flat dentinal surface. The teeth were embedded in the resin in separate molds and were divided into three equal groups of fifteen samples each Group 1: Samples treated with Tooth Mousse for 60 min daily for 7 days and then restored with GB and composite (Filtek Z350, 3M ESPE). Group 2: Samples treated with Tooth Mousse and etched with phosphoric acid prior to restoration with GB and composite. Group3: Samples restored with GB and composite. A split brass mold was placed over the predesigned location and with help of the plasma coated instrument, composite resin was placed. Tensile loading was done using Universal Testing Machine. Conclusion: TBS of GB was not significantly reduced after CPP-ACP application, but after prior etching the CPP-ACP specimens, the bond strength of GB was significantly reduced.

SUMMARY The aim of this in vitro study was to investigate the effect of the cariostatic and preventive agent silver diamine fluoride (SDF) on the microtensile bond strength of resin composite to dentin. Forty-two caries-free, extracted molars were flattened occlusally and apically using a diamond saw, and the exposed occlusal dentin was polished with a series of silicon carbide papers, all under water irrigation. The teeth were then randomly divided into six groups of seven teeth each that were treated as follows: 1) Peak SE self-etch bonding agent; 2) 12% SDF + Peak SE; 3) 38% SDF + Peak SE; 4) Peak LC etch-and-rinse bonding agent; 5) 12% SDF + Peak LC; and 6) 38% SDF + Peak LC. Four-millimeter buildups of Amelogen Plus were incrementally placed on all teeth; after a 24-hour storage period in distilled water, the specimens were sectioned perpendicular to the adhesive interface to produce beams of cross-sectional surface area measuring approximately 1 mm2. The beams were placed on a microtensile testing machine, which utilized a single-speed pump motor and force gauge at 20 kgf × 0.01 second to record maximum tensile force before failure occurred. Two-way analysis of variance and post hoc Tukey tests were performed to compare the effects of the SDF on microtensile bond strength, with statistical significance set at α = 0.05. None of the experimental groups treated with different concentrations of SDF showed a significant difference in bond strength compared to the control groups, and there was no significant difference in bond strength between self-etch and etch-and-rinse groups. However, the effect of SDF on self-etch bonded teeth compared to etch-and-rinse bonded teeth was statistically significant (p=0.0363), specifically at the 12% concentration. SDF does not adversely affect the bond strength of resin composite to noncarious dentin.
