Novel in vitro comparative model of osteogenic and inflammatory cell response to dental implants
Roughened dental implants promote mesenchymal stem cell (MSCs) osteoblastic differentiation, and hydrophilic modifications induce anti-inflammatory macrophages activation. While the effect of different surface modifications on osseointegration of commercial dental implants have been compared in vivo and clinically, the initial cellular response to these modifications often overlooked. We aimed to characterize the macrophage inflammatory response and MSC osteogenesis across different commercially available implants in vitro. (Source: Dental Materials)

Residual strain mapping through pair distribution function analysis of the porcelain veneer within a yttria partially stabilised zirconia dental prosthesis
In recent decades the high strength, high toughness, excellent biocompatibility and appealing aesthetics of Yttria Partially Stabilised Zirconia (YPSZ) has ensured that this ceramic has become the restorative material of choice used in premium dental prostheses [1]. During the manufacture of these copings, YPSZ is coated with a porcelain veneer in order to match the shade and pearlescence of the patients ’ existing teeth and to reduce wear during occlusal contact [2]. However, along with these benefits this manufacturing approach is known to induce the primary failure mode of these prostheses: near interface chipping of ...

Exceptional contact elasticity of human enamel in nanoindentation test
Natural biominerals have long inspired researchers to conceptualize new functional materials for human health and industrial applications because the natural material characteristics that meet the multifunctional criteria are often superior to those of similar synthetic materials [1 –3]. In particular, tooth enamel is the hardest and stiffest mineralized biological tissue, which allows it to exhibit remarkable resilience throughout the life of an individual, despite it comprising only the thin outer covering of the tooth [2].

Influence of placement instruments on handling of dental composite materials
Applicability and stickiness of dental composites are influential factors for the properties of those materials and so indirectly affect function, longevity and esthetics of composite restorations in the clinic. Thus, this in vitro study aimed for the influence of different placement instruments ’ diameter, geometries and coatings on the handling of uncured resin composite materials.

Physical properties and cytotoxicity of antimicrobial dental resin adhesives containing dimethacrylate oligomers of Ciprofloxacin and Metronidazole
Resin composites are the most widely used dental restorative material [1]. Resin composites are bonded to teeth using adhesive systems, which seal the interface by replacing some of the inorganic tooth component with resin monomers. The latter bond by mechanically interlocking into the tooth structure upon polymerization [2]. Two main types of adhesive systems used commercially are the etch-and-rinse (E&R) systems, also known as total etch, which remove the smear layer (a thin layer of debris remaining on the tooth surface after dental instrumentation procedures) and the self-etch adhesive systems that modify the smear lay...

Positive correlation between fluoride release and acid erosion of restorative glass-ionomer cements
Dental caries is a dynamic process [1] and recently better understanding of the disease has led to minimal invasive management instead the traditional operative approach [2]. As a suitable material and the first to represent bioactive restorative materials, glass ionomer cements are the materials of choice when caries activity is high [3]. (Source: Dental Materials)

Impaired angiogenic differentiation of dental pulp stem cells during exposure to the resinous monomer triethylene glycol dimethacrylate
Dental pulp stem cells (DPSCs) can differentiate into tissue specific lineages to support dental pulp regeneration after injuries. Triethylene glycol dimethacrylate (TEGDMA) is a widely used co-monomer in restorative dentistry with adverse effects on cellular metabolism. Aim of this study was to analyze the impact of TEGDMA on the angiogenic differentiation potential of DPSCs. (Source: Dental Materials)
