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...

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 purpose of this study was to investigate the shear bond strength of metal discs luted to dentine using Resin Coating Technique. In this study the adhesives used were dentine bonding agents, namely, Clearfil SE Bond and Syntac Sprint which were applied one week prior to cementation of Cobalt Chromium (Co-Cr) alloy discs to determine if there was any increase in the bond strengths when later ...

Matrix metalloproteinases (MMPs) have been studied extensively, and MMP inhibitors have been used as dental pretreatment agents prior to dentin bonding because they reduce collagen fiber degradation and improve bonding strength. However, morphologic characteristics of the collagen network after etching and of the post-adhesive dentin hybrid layers (DHL) after MMP inhibitors pretreatment have no...

OBJECTIVES This study investigated the shear bond strength (SBS) and the tensile bond strength (TBS) of the zirconia-to-resin interface using different cement bonding concepts. METHODS Coplanar zirconia specimens were bonded to CoCr-cylinders measuring 5 mm in diameter and 3 mm in height. All bonding areas were first sandblasted with 110 μm Al(2)O(3) (0.28 MPa, 10 s). SBS and TBS were determi...

Aim Conservative procedures using dentin bonding agents are one of the important aspects of paediatric dental practice. The objective of this in vitro study was to comparatively evaluate the microleakage of two self etching adhesives in primary and permanent teeth. Materials and methods Sixtyfour human anterior teeth (thirty-two primary and thirty-two permanent) were divided into four groups: p...

Information dentaire n° 26 du 27 juin 2001 When faced with dental root fractures, the practitioner is often at a disadvantage, particularly in emergency situations. Treatments which have been proposed, particularly symptomatic in nature, have irregular long-term results. The spectacular progress of bonding materials has radically changed treatment perspectives. Among these bonding agents, the 4...

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...
