Objectives. To examine the effect of immediate dentin sealing (IDS), with dentin bonding agents (DBAs) applied to freshly cut dentin, on the shear bond strength of etched pressed ceramic luted to dentin with RelyX Unicem (RXU) cement.Method. Eighty extracted noncarious third molars were ground flat to expose the occlusal dentin surfaces. The teeth were randomly allocated to five groups (A to E) of sixteen teeth each. Groups A to D were allocated a dentin bonding agent (Optibond FL, One Coat Bond, Single Bond, or Go!) that was applied to the dentin surface to mimic the clinical procedure of IDS. These specimen groups then had etched glass ceramic discs (Authentic) luted to the sealed dentin surface using RXU. Group E (control) had etched glass ceramic discs luted to the dentin surface (without a dentin bonding agent) using RXU following the manufacturer’s instructions. All specimens were stored for one week in distilled water at room temperature and then shear stressed at a constant cross-head speed of 1 mm per minute until failure. Statistical analysis was performed by ANOVA followed by post hoc Tukey HSD method () applied for multiple paired comparisons.Results. The shear bond strength results for group A to E ranged from to  MPa. One-way ANOVA demonstrated a difference () between the groups tested and the Tukey HSD demonstrated a significant () difference between the shear bond strength (SBS) of Optibond FL (Group A) and Go! (Group D). There was no statistical difference () in the SBS between the test groups (A–D) or the control (group E).Conclusion. IDS using the dentin bonding agents tested does not statistically () affect the shear bond strength of etched pressed ceramic luted to dentin with RXU when compared to the control.

Purpose: The purpose of this study was to evaluate the immediate bond strength of two sixth generation and two seventh generation dentin bonding agents to superficial dentin. Specimens were prepared to exposed superficial dentin and either Clearfil SE, Clearfil S3, Adper Prompt-l-pop of G-bond was applied over the dentin surface and light cured. Then composite resin was applied to the treated surface and light-cured in two increments. Specimens were tested 15 minutes after they were made for shear bond strength at 0.01 cm/min. Clearfil SE had statistically higher bond strength than the other three adhesives evaluated (42.9 MPa). There was no statistical difference among Clearfil S3, Adper Prompt-l-pop and G-Bond. The dentin adhesive with an application of an acidic primer before the application of the adhesive showed better immediate bond strength.

Abstract Introduction The silanization of the ceramic surface prior to applying the adhesive and/or resinous materials plays an important role in bond strength. Nowadays, a new family of adhesive systems has been introduced into the market, aiming to simplify the technique of adhesive procedures during cementation. Objective To investigate the effectiveness of different bonding agents containing silane and primer on Lithium Disilicate Glass Ceramic (LD) surface by shear bond strength tests. Material and method 130 LD ceramic blocks were included in acrylic resin, polished and washed in ultrasound for 10 minutes. The specimens were divided into 2 groups according to surface treatment: Polished Surface (PS); Hydrofluoric Acid 9.5% - 20s (HF). Each group was divided into 5 subgroups (n = 13) according to bonding agent type: metallic primer containing MDP (ZPrimePlus, Bisco Inc); two traditional silanes (MonobondPlus, IvoclarVivadent / Porcelain Prime, Bisco Inc.); mixture of silane and resin (Kerr Silane, Kerr); mixture of silane and universal adhesive (Single-bond Universal, 3M Espe). The specimens were mounted in a standard device for shear testing (UltradentBonding Assembly), cemented with dual resin cement (RelyX UltimateTM, 3M Espe.) and photo-polymerized for 20s. The samples were tested after 24 hours and 3 months of storage in distilled water at ±36 °C. The data were analyzed by 3-Way Anova and Tukey's test (α = 5%). Result Shear bond strength (SBS) was significantly influenced by surface treatment, bonding agent used and storage (p <0.001). Conclusion Adequate adhesive bond strength to Lithium Disilicate Glass Ceramic can be obtained with traditional silanes, combined with HF acid pretreatment surface.

Dentin bonding agents are resin based materials that used in clinical dentistry inorder to prevent leakage and promote adherent of filling material to the enamel anddentin. However, the polymerization of dentin bonding agents will release residualmonomer that may interact with pulp tissue. This in vitro study is aimed to evaluatethe cytotoxicity of new 7thgeneration dentin bonding agents (G Bond) on stem cellsfrom human exfoliated deciduous teeth (SHEDs). The proliferated human pulp cellswere incubated at 37 C for 48 hours. Under aseptic conditions, extracted testspecimen were plated in 96 well of tissue tray. SHEDs were placed on each well withdifferent concentration of dentin bonding agents, and then incubated at 37 C for 72hours exposure. The cytotoxic effect was recorded by using MTT assay method.Statistical analysis showed that higher concentration of dentin bonding agents (IC=0.035 mg/ml)exerts higher toxic effect to the human pulp cells (SHEDs). This studyconcluded that pulpal reaction to dentin bonding agent may depend on number ofapplication procedure.
