INTRODUCTION Worldwide the use of amalgam has declined and mercury-containing products are banned in several countries. National and international opinions on amalgam were recently discussed in journals. According to surveys, significant time is spent on the teaching of amalgam in American, Canadian, Irish and United Kingdom Dental Schools. AIMS AND OBJECTIVES To i) investigate the teaching a...

The paper reviews data on biological side-effects of dental materials on patients and also on personnel who routinely handle the materials. The incidence of adverse effects is low--in one study indicated to be 1:700 for all types of treatments. For individual types of materials, it will be significantly lower, and for restorative materials, probably in the 1:10,000 to 1:20,000 range. Allergic r...

the interest of dental research in metal-free restorations has been rising in the last 20 years following the introduction of innovative all-ceramic materials in the daily practice. in particular, high-strength ceramics and related cad/cam techniques have widely increased the clinical indications of metal-free restorations, showing more favorable mechanical characteristics compared to the early...

Two composite resins (Ful-Fil ® and X-55®) were placed in the primary molars of 50 children aged 4 to 8 years. A total of 357 restorations were placed in 3 different cavity preparations. The restorations were evaluated by 2 investigators at 0, 6, 12, 24, and 36 months using the USPHS evaluation criteria. At 48 months 130 restorations were available for evaluation. This represents a recall rate ...

The evolution of computerized systems for the production of dental restorations associated to the development of novel microstructures for ceramic materials has caused an important change in the clinical workflow for dentists and technicians, as well as in the treatment options offered to patients. New microstructures have also been developed by the industry in order to offer ceramic and compos...

BACKGROUND Resin-based composites are an increasingly popular material for restoring posterior teeth, permitting minimally invasive cavity preparations and esthetic restorations. The authors investigated current teaching of the placement of posterior resin-based composites in U.S. and Canadian dental schools. METHODS In late 2009 and early 2010, the authors, with the assistance of the Consort...

A major undertaking for general practitioners is the provision and assessment of dental restorations. High quality restorative therapy encompasses several key elements that fulfil specific criteria. Enhanced knowledge of these elements is a significant step toward improvement of the quality of restorative dental care 1. Several studies have demonstrated that a major component of a dentist’s wor...

Alumina- and zirconia-based ceramic dental restorations are designed to repair functionality as well as esthetics of the failed teeth. However, these materials exhibited several performance deficiencies such as fracture, poor esthetic properties of ceramic cores (particularly zirconia cores), and difficulty in accomplishing a strong ceramic-resin-based cement bond. Therefore, improving the mech...

This case report describes the fabrication of monolithic all-ceramic restorations using zirconia-reinforced lithium silicate (ZLS) ceramics. The use of powder-free intraoral scanner, generative fabrication technology of the working model, and CAD/CAM of the restorations in the dental laboratory allows a completely digitized workflow. The newly introduced ZLS ceramics offer a unique combination ...

conclusions the most common cause of restoration replacement in patients referred to the babol university of dentistry during years 2013 and 2014 was secondary caries that were found in class ii restorations. patients and methods age, sex, type of occlusion, dmf, existing parafunction, type of tooth, class and reason of composite restoration replacement was recorded for patients who had referre...
