As dentistry continues to evolve, new technologies and materials are continually being offered to the dental profession. Throughout the years restorative trends and techniques have come and gone. Some material developments have transformed the face of esthetic dentistry, while other initial concepts have already phased out and disappeared. Today, all-ceramic restorations continue to grow in the...

Wear of restorative materials has been characterized in vitro using single-pass sliding.'4 Wear patterns and surface structures of composite restorations in vivo have been reported by Kusy and Leinfelder5 and by O'Brien and Yee.6 However, there have been few reports on the correlation between in vitro and in vivo wear. One reason could be that the in vivo wear characteristics result from gradua...

The purpose of this study was to evaluate the effect of sports and energy drinks on the surface hardness of different restorative materials over a 6-month period. Forty-two disk-shaped specimens were prepared for each of the four restorative materials tested: Compoglass F, Filtek Z250, Filtek Supreme, and Premise. Specimens were immersed for 2 min daily, up to 6 months, in six storage solutions...

UNLABELLED Many different restorative materials are currently available for use in modern dentistry. Clinicians and dental technicians should be able to choose the most suitable materials for each patient based on research, anecdotal evidence, clinical experience, as well as patient's expectations and desires. The purpose of this article is to share the challenges presented in full-mouth rehabi...

Bioactive materials have evolved over the past three decades from relatively specialized, highly biocompatible, but low-strength dental materials to new compositions for expanded use in restorative dentistry. The objective of this review is to understand the concept of bioactivity and to compare and contrast the various bioactive materials while shedding light on new applications for this evolv...

This report documents treatment and repair of three carious teeth that were restored with a new dental repair material that features the characteristics of both resin-modified glass-ionomer restorative cement (RMGI) and resin-based composite (RBC). The restorative products presented are reported by the manufacturer to be the first bioactive dental materials with an ionic resin matrix, a shock-a...

objective: the aim of this study was to investigate the translucency of resin-modified glass-ionomer cements (rmgic) and polyacid-modified composite resin (pcmr) over a period of one year. materials and methods: the study was done on three rmgic (fuji ii lc, photac-fil aplicap and vitremer) and one pcmr (dyract). a conventional gic (fuji cap ii) and two composite resins (tetric and z 100) were ...

BACKGROUND In the mid of 1980s, the cariostatic effect of fluoride ions on enamel caries had been demonstrated in many studies. The use of fluoride releasing dental restorative materials has seen increasing from many years for the specific purpose of leaching of fluoride into the surrounding tissues to inhibit secondary dental caries as well as prevention of caries in the newly erupted tooth. I...

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...
