AIM The aim of this in vitro study was to determine the two-body wear resistance of modern direct dental restorative materials. METHODS Eight standardized specimens were prepared from 14 dental restorative materials (nano-, micro-, hybrid-, macrofilled composites; compomer, silorane, ormocer); a veneering composite (Sinfony) and enamel were used for reference. Vickers hardness (HV) and inorga...

There are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (CH), adhesive systems, resin composite and glass ionomer cements. The aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for protection of the dentin-pulp complex, some components of resin composites an...

Polyetheretherketone (PEEK) is a kind of synthetic thermoplastic polymer, because of its good biological compatibility, chemical stability and radiolucency, it has been widely used in the field of medicine. Compared with the titanium, the elastic modulus of PEEK is closer to human cortical bone, PEEK could be a viable alternative material for dental implants. Nevertheless the inherent bio-inert...

Resin-based dental restorative materials are extensively used today in dentistry. However, significant concerns still remain regarding their biocompatibility. For this reason, significant scientific effort has been focused on the determination of the molecular toxicology of substances released by these biomaterials, using several tools for risk assessment, including exposure assessment, hazard ...

OBJECTIVES The objective is to review the current state of the art of dental composite materials. METHODS An outline of the most important aspects of dental composites was created, and a subsequent literature search for articles related to their formulation, properties and clinical considerations was conducted using PubMed followed by hand searching citations from relevant articles. RESULTS...

In recent years, the increasing demand for aesthetically appealing, naturally-coloured dental restoration options has given rise to a growth in the use of composites in the posterior dental area [1-5]. The declining acceptance of dental amalgam and the mercury problem also makes an alternative to amalgam necessary [6,7]. In a statement from the German Scientific Association for Operative Dentis...

The sizes for the perceptible or acceptable color difference measured with instruments vary by factors such as instrument, material, and color-difference formula. To compensate for disagreement of the CIELAB color difference ( E*ab) with the human observer, the CIEDE2000 formula was developed. However, since this formula has no uniform color space (UCS), DIN99 UCS may be an alternative UCS at p...

INTRODUCTION This study aimed to evaluate the potential applications of polycaprolactone (PCL)/submicron bioactive glass (smBG) hybrid composites for pulp and dentin tissue regeneration. METHODS PCL/smBG hybrid composites were made with novel monodispersive bioactive glass submicrospheres, and pure PCL and bioactive glass samples were used as controls. Surface characteristics were assessed by...

This in vitro study investigated the aging behavior of dental composites with regard to surface roughness (SR), Vickers hardness (VH) and flexural strength (FS), and the study elucidated the impact of artificial aging parameters. One hundred and sixty-five rectangular specimens were prepared from five composites (Filtek Supreme XT, Filtek Silorane, CeramX, Quixfil, experimental ormocer) and sub...
