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...

Aim: This study was done to evaluate the rate of microleakage in class V amalgam restorations in which the dental bonding agent (DBA) Excite was used as a sealer beneath the restorations. Methods: four amalgam restorative materials with commercial names of Dentam, Cinalux, Tytin and SDI (GS-80) were used. Seventy sound human premolars were selected and randomly divided into 4 groups of 15 teeth...

statement of problem: in some clinical situations, repair of composite restorations is treatment of choice. improving the bond strength between one new and old composite usually requires increased surface roughness to promote mechanical interlocking since chemical bonding might not be adequate. similarly, the treatment of a laboratory fabricated resin composite restoration involves the same pro...

UNLABELLED The purpose of this article is to review evidence-based principles that could help optimize dentin bonding for indirect composite and porcelain restorations. More than 30 articles were reviewed, most of them addressing the specific situation of dentin bonding for indirect restorations. It appears that the combined results of this data plus clinical experience suggest the need for a r...

The purpose of this study was to evaluate the microtensile bond strength (microTBS) to human dentin of an experimental bonding agent containing calcium phosphates experimentally developed for direct pulp capping. Different concentrations of four types of calcium phosphates were added to an experimental bonding monomer, and six experimental bonding agents were thus prepared. Clearfil SE Bond/Bon...

Presently, resin composites are indispensable for dental restorative treatment because of their favorable esthetic and mechanical properties. In particular, the adhesion of resin composites to dentin has been rapidly improved by progress resin adhesive systems. Of late, resin restorative procedures have been simplified with the development of adhesive systems with fewer processing steps. One of...
