Background and Aim: The aim of this study was to evaluate the micro-shear bond strength of an indirect composite resin to three different types of cores. Materials and Methods: In this in-vitro study, 14 blocks (5×5×2 mm) were designed and milled by computer from cobalt-chromium (Co-Cr) alloy, zirconia, and polyether ether ketone (PEEK). Each sample was treated according to the manufacturer’s ...

Characterising powder flowability can be a challenge if only small quantity of samples is available, e.g. pharmaceutical formulations. The paper focuses on new method for assessing based physical properties and cohesiveness particles using few grams powders. technique applies Bond number to represent cohesiveness, which detects particle adhesion at median size mechanical surface energy tester d...

introduction: incomplete anesthesia of inflamed teeth is a well known clinical occurrence and the purpose of this study was to evaluate the effectiveness of ibuprofen as a premedication in improving the quality of anesthesia in patients with inflamed teeth pulps. methods: forty patients with the diagnosis of irreversible pulpitis in one mandibular tooth were selected. two other teeth in the sam...

BACKGROUND Although bonding to denture teeth after surface treatment with chemical agents is desirable, there is little information on the use of Visible Light Cure composite resin (VLC) as bonding denture materials. OBJECTIVES To determine the effect of various surface treatments on shear bond strength between Visible Light Cure composite resin and the acrylic denture teeth interface. METH...

This in vitro study evaluated the influence of two devices for application of shear load in microshear tests on bond strength and fracture pattern of primary enamel and dentin. Eighty primary molars were selected and flat enamel (40 teeth sectioned mesio-distally) and dentin (40 teeth sectioned transversally) surfaces were obtained. Both surfaces were polished to standardize the smear layer. Tw...

In our previous paper [Watano S. et al., J. Powder Technology Japan, 37, 362-370 (2000)], a novel compaction tester was developed to quantitatively evaluate the water dispersion condition of a wet kneaded mass prepared by a paddle type kneader. It has been demonstrated that the physical properties of pellets prepared by extrusion granulation after the kneading can be well predicted by the press...
