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...

Direct application of dentin bonding agents onto the exposed pulp has been advocated, but in vivo studies indicate a lack of reparative dentin formation. Our objective was to investigate the role of triethylene glycol dimethacrylate (TEGDMA), a commonly used compound in dentin bonding agents, as a potential inhibitor of mineralization. Human pulp cells were exposed to different concentrations o...

The aim of this study was to enhance the bond strength of one-step bonding agents to dentin. In particular, the focus was on using Catabrush the applicator system of AQ Bond Plus. Catabrush was supplemented with N-phenylglycine and aromatic sulfinate as polymerization accelerators, as N-phenylglycine was reportedly beneficial in improving the bond strength to dentin. The results indicated that ...

The effect of momentary pretreatment by 35% HEMA solution on the adaptation between dentin and resin material was investigated by measuring wall-to-wall polymerization contraction in a cylindrical dentin cavity. Five marketed bonding agents tested in this study exhibited improved marginal seal when the dentin cavity wall was pretreated by 35% HEMA for a few seconds with the exception of Pyrofi1...

OBJECTIVES Polymerized dental resin materials release residual monomers that may interact with pulp tissues. We hypothesized that dental adhesives might cause cytotoxicity in pulp cells via the generation of reactive oxygen species (ROS), which may also contribute to genotoxic effects in vitro. METHODS For cytotoxicity testing, transformed human pulp-derived cells were exposed to extracts of ...

This study explored the factorial structure of the Parental Bonding Instrument (PBI) in the Japanese population. Several differences between the structure model in the current study and Parker et al.'s original model were identified. We also examined the adaptability of the inventory to children currently being raised by parents. We also developed a structural equation model that takes into acc...

The reaction of three-dimensional cultures of pulp-derived cells in a dentin barrier test was recorded after exposure to All-Bond 2, Prime & Bond NT, Syntac SC, Syntac Classic, and Prompt L-Pop. The materials were applied on bovine dentin disks in a perfusion chamber, and the experiments were performed with (0.3 ml/h, 2 ml/h) and without perfusion of the pulpal part of the chamber. The cell rea...

Background: To conserve the tooth structure, bonded restorations are popular nowadays. Bonding to enamel is predictable by acid-etch technique. However, bonding dentin remains a challenge. Aim: determine better agent between universal and total-etch agents based on shear bond strength using testing machine.
 Methodology: Eighteen human permanent mandibular molars were sectioned longitudina...
