Background: Prompt L-Pop is a self-etching dentin adhesive, which is recommended to use with both compomers and composite resins. The aims of this investigation were to determine and compare the microleakage, shear bond strength, and shear push out strength of composite and compomer to dentin with application of Prompt L-Pop as adhesive system. Methods: After application of Prompt L-Pop on the ...

Objective: To evaluate the effect of different irradiation times on the occlusion of dentinal tubules when using Nd:YAG laser. Background data: Dentin hypersensitivity is a frequent problem that has limited treatment success despite many chemical and physical therapies. Methods: Four coronal dentin disks 2 mm thick were cut with a low-speed diamond saw from four freshly extracted intact first m...

INTRODUCTION The purpose of a desensitizing agent is a permanent coating or filling of dentin surface. Morphological analysis in vitro of this treated surface is essential to understand the interaction between desensitizing agent and hypersensitive dentin. The aim was to evaluate the morphology of four dentin surface treated with desensitizing agents. METHODS This was an in vitro laboratory s...

introduction : recent investigations have attempted to improve regenerative endodontics with the help of stem cell therapy. in vitro studies have shown the ability of different agents to stimulate the differentiation of dental pulp stem cells (dpsc) into odontoblast-like cells. a combination of dexamethasone, β-glycerophosphate and vitamin d has been proven to induce a successful differentiatio...

BACKGROUND Ultrasonic irrigation has been proved for its remarkable cleaning efficiency in the field of endodontics. But its role in endodontic re-treatment has been understated. There is not much data available to understand the effect of ultrasonic irrigation for the evaluation of cleanliness of dentinal tubules when it is used with or without chloroform, a gutta percha solvent during endodon...

UNLABELLED There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy dentinal tissue. OBJECTIVES The purpose of this study was to test different methods for the detection of carious dentinal tissue regarding the amount of carious tissue removed and the remaining dentin microhardness after caries removal. MATERIAL AND METHODS The dentin surfaces of ...

background and aims. the aim of the present study was to compare 1.3% sodium hypochlorite (naocl) in mtad (mixture of tetracycline isomer, acid, and detergent) for the removal of the smear layer and induction of canal erosion. materials and methods. 38 maxillary incisors were divided in three experimental groups of 10 and two positive and negative control groups of each 4 teeth, and prepared us...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...
