A good adhesive is an important factor to consider in orthodontic bonding. Frequent bracket failure prolongs treatment duration and causes inconvenience to patient and operator. This study aimed to compare the effectiveness of two bonding agents, i.e. the self etching primer (SEP) and the conventional etch and bond (CEB) by monitoring the incidence, time and sites of bracket failure. Eighty ort...

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...

introduction: the aim of this study was to compare the shear bond strength of a self-adhering flowable composite (safc) and resin-modified glass ionomer (rmgi) to mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement. methods and materials: a total of 72 acrylic blocks with a central hole (4 mm in diameter and 2 mm in depth) were prepared. the holes were filled with mta (su...

Regardless of bleaching regimes, the bond strength of composite resin or resin cement is reduced when bonding procedure is performed immediately after whitening. It is believed that the polymerization via free-radical mechanism is impeded by nascent oxygen remnant and peroxide in the bleached dental hard tissue. Because sodium hydroxide is used as a buffering agent to control the decreased pH, ...

The relatlon between the bonding eMcacy ef the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated, The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized O,5M EDTA solution (pH7.4) and 9.1% pyruvic acid containing 9,1% glycin, prior to the comb...

The bonding ability of bonding agents and composites from three manufacturers, which have both chemically and visible light activated systems, were evaluated by measuring the contraction gap width between the material and the cavity wall in a dentin cavity. The visible light cured composites were inferior to the same manufacturer's chemically cured composites in marginal adaptation to a cylindr...
