Besides functional and cross-linking monomers, dental adhesives contain a photo-initiator system for polymerization, thereby providing physico-mechanical strength to the adhesive-tooth interface. Few studies have investigated the effect of the functional monomer and polymerization-initiation system on the polymerization efficiency of the adhesive. Here, we tested the effect of two different fun...

submitted to different surface treatments. Forty-eight maxillary canines had their crowns sectioned and root canals endodontically treated. The roots were embedded in acrylic resin and distributed into 3 groups according to the surface treatment: Group I: the posts were treated with silane agent for 30 s and adhesive; Group II: the posts were cleaned with alcohol before treatment with silane ag...

objective(s):serratia marcescens is one of the nosocomial pathogen. the ability to form biofilm is an important feature in the pathogenesis of s. marcescens. the aim of this study was to determine the anti-adhesive properties of a biosurfactant isolated from lactobacillus acidophilus atcc 4356, on s. marcescens strains. materials and methods: lactobacillus acidophilus atcc 4356, was selected as...

INTRODUCTION The ultimate goal in restorative dentistry has always been to achieve strong and permanent bond between the dental tissues and filling materials. It is not easy to achieve this task because the bonding process is different for enamel and dentin-dentin is more humid and more organic than enamel. It is moisture and organic nature of dentin that make this hard tissue very complex to a...

The purpose of this study was to estimate the impact of adhesive capsulitis on costs and health and to compare the cost-utility of high-grade and low-grade mobilisation techniques. In a randomised controlled trial, 92 patients with adhesive capsulitis received either high-grade mobilisation techniques or low-grade mobilisation techniques and were followed for one year. Outcome measures were qua...

OBJECTIVES to evaluate the effect of different conditioning treatments on surface roughness and topography of dental cementum. STUDY DESIGN Extracted human canines were used for the present study. The mesial surface from the cervical third of the roots were ground flat with wet 600-grit silicon carbide paper. They were polished (up to 1/4 µm diamond paste) and treated as follows: 1) No treatm...

Although the adhesion phenomenon is crucial in achieving and maintaining a composite building on dental structure, this phenomenon is not completely understood. On the other hand, adhesion is dependent on the interface quality (the interface between enamel and adhesive). In this study, the authors approached the subject of the influence of adhesive clinical application on the composite-enamel i...
