Use of Vitremer Core Buildup/Restorative Cement (3M Dental Products Division) as a luting cement for orthodontic bands and space maintainers was described in 1994. For use as a luting agent, the restorative cement is mixed with a slightly lower powder liquid ratio so the blend is more fluid than one used for a dental restoration. A chief advantage of using Vitremer Restorative Cement for luting...

INTRODUCTION Since it is not possible to form an adequate micromechanical bond between resin cement and zirconia ceramics using common surface treatment techniques, laser pretreatment has been suggested for zirconia ceramic surfaces. The aim of this study was to evaluate the effect of Carbon Dioxide (CO2) Laser treatment on shear bond strength (SBS) of resin cement to zirconia ceramic. METHOD...

OBJECTIVES It is difficult to achieve adhesion between resin cement and zirconia ceramics using routine surface preparation methods. The aim of this study was to evaluate the effects of CO2 and Er:YAG laser treatment on the bond strength of resin cement to zirconia ceramics. MATERIALS AND METHODS In this in-vitro study 45 zirconia disks (6 mm in diameter and 2 mm in thickness) were assigned t...

OBJECTIVES The influence of light transmitting ability of different fibre posts on the polymerization of a dual-cured resin cement, and the further microleakage of the post-restored endodontically treated teeth were examined. METHODS An LED curing light was used as light source and the measurements of 470 nm irradiances were made at 1mm intervals along the posts (P-Lux, P-White, and P-Steel)....

objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...

BACKGROUND The resistance form is a key factor for a successful crown fabrication. This in vitro study evaluates the effects of proximal grooves and abutment height on the resistance of single cast crowns in molars with inadequate resistance. METHODS Sixty extracted human molars were prepared to possess 20° of total occlusal convergence for single crown fabrication. All of the prepared teeth ...

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...

The purpose of this study was to evaluate the compressive strength of two glass ionomer cements, a conventional one (Vitro Fil - DFL) and a resin-modified material (Vitro Fil LC - DFL), using two test specimen dimensions: One with 6 mm in height and 4 mm in diameter and the other with 12 mm in height and 6 mm in diameter, according to the ISO 7489:1986 specification and the ANSI/ADA Specificati...

Enamel demineralization is an undesirable but common complication of orthodontic fixed appliances therapy. The purpose of this study was to test long-term benefits of resin-modified glass ionomer cement (GC Fuji OrthoTM LC) for the prevention of demineralization in patients receiving orthodontic treatment with fixed bonded appliances. 90 healthy extracted premolars without any clinical signs of...

Glass ionomer cements (GICs) are widely used in restorative dentistry.1 In dentistry, one of their advantages over other restorative materials is that they can be placed into tooth cavities without an additional bonding agent.2 They also possess a fluoride-releasing property3 and are relatively biocompatible with the pulp.1 Adhesive property and fluoride release of glass ionomer cement contribu...
