Background and Aims: The aim of the present study was to evaluate the effect of applying hydrophobic resin after use of different generation of the bonding systems on nanoleakage. Materials and Methods: 20 third molar teeth were selected. The teeth were randomly divided into 4 groups of 5, each was treated using the fourth, fifth, sixth, and seven generation of dentin bonding. Then, the crown ...

BACKGROUND The purpose of this study was to evaluate the effect of glycine pretreatment on the shear bond strength between dentin and a CAD/CAM resin nano ceramic material (LavaTM Ultimate Restorative), bonded together with adhesive cements using three different luting protocols (total-etch; self-etch; self-adhesive). MATERIAL AND METHODS Thirty cylinders were milled from resin nano ceramic b...

The purpose of this study was to evaluate the five-year clinical performance of a two-step self-etch adhesive in non-carious cervical sclerotic lesions with or without selective acid-etching of enamel margins. A total of 104 cervical restorations in 22 patients (46-64 years) were bonded following either self-etch approach (AdheSE non-etch) or a similar application, including selective acid-etch...

Introduction: This study evaluated microleakage of flowable and conventional composite in primary molar class II restorations using self-etch and total-etch bonding agents. Methods: Class II standard cavities were prepared on proximal surface of 48 primary molars. These cavities were restored using GrandioFlow and Grandio composites and Futurabond DC and Solobo...

Introduction: Thermocycling is used in most invitro studies to produce conditions similar to clinical studies, but results about the effect and number of thermocycling cycles have been different in different studies. The purpose of this study was to evaluate the effect of thermocycling on microleakage of self and total etch bondings in class V resin composite restorations. Methods: A total of...

Reactive ion etching is a widely-used technique for fabricating via holes in polymer-metal multilayer interconnect structures. Reactive ion etching of thin film polymers was studied using Benzocyclobutene polymer and photoresist etch mask, in O2 and SF6 plasma. A design of experiments (DOE) was carried out with rf power, pressure, and SF6 concentration as the design variables, with a constant t...

Restorative dentistry is mainly based on good adhesion between restorative materials and dental substrates; while adhesion to enamel is generally reliable, adhesion to dentin is less predictable (1) because of the presence of dentinal tubulis and the perfusion of liquids from it. Adhesion to dentin requires demineralization of peritubular and intertubular dentin to replace the demineralized lay...
