In-vitro and in-vivo design and validation of an injectable polysaccharide-hydroxyapatite composite material for sinus floor augmentation
Polysaccharide-based composite matrices consisting of natural polysaccharides, pullulan and dextran supplemented with hydroxyapatite (Matrix-HA) have recently been developed. The principal objective of this study was to evaluate the capacities of this composite material to promote new bone formation in a sinus lift model in the sheep. Secondary objectives were to evaluate in vitro properties of the material regarding cell adhesion and proliferation. (Source: Dental Materials)

Influence of Class V preparation on in vivo temperature rise in anesthetized human pulp during exposure to a Polywave ® LED light curing unit
Over the last decades, powerful light emitting diode (LED) light curing units (LCU) have become available in order to provide optimal mechanical properties of photoactivated, resin-based composites and to reduce the time required for clinicians to accomplish restorative procedures. In this context, LED LCUs with radiant emittance values exceeding 2000mW/cm2 are now commercially available. Thus, the heat generated in target tissues by such devices has become an issue.

Aging resistance, mechanical properties and translucency of different yttria-stabilized zirconia ceramics for monolithic dental crown applications
The dental market moves towards high-translucency monolithic zirconia dental crowns, which are usually placed either with – or without – a thin glaze layer. The microstructural features and the mechanical performances of these materials are still controversial, as well as their susceptibility to aging. This paper aims at studying these aspects in the current generation of zirconia dental crowns showing different de grees of translucency. (Source: Dental Materials)

Fatigue failure load of two resin-bonded zirconia-reinforced lithium silicate glass-ceramics: Effect of ceramic thickness
Nowadays, the concept of monolithic full-contour restorations using Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) technology has been considered as an alternative to the conventional restorative approaches for fixed dental prostheses (FDPs) [1]. This restorative alternative allows a substantial reduction of the ceramic thickness in accordance with the concept of minimally invasive dentistry, which emphasizes the use of high-resistance materials in association with adhesive luting techniques to restore teeth [2].

Bioactive dental materials —Do they exist and what does bioactivity mean?
Successful dental restorative and prosthetic treatment outcomes require interfacial adhesion of materials to under-laying dental hard tissues sufficient to withstand external occlusal loads. Interfacial adhesion is normally achieved using resin based adhesives and priming compounds whereas the integrity of natural interphases of hard tissues are achieved via a mainly mineralized constitution. Dental hard tissues of dentin, enamel and cementum incorporate calcium phosphate minerals of carbonated hydroxyl apatite and the interface between the tissues are also typically toughened via collagen fibrils.
