Resin-based composite restorations were introduced in dentistry about a half century ago as an esthetic restorative material 56 57 and composites increasingly are used in place of amalgam for the restoration of carious lesions 58 Composites consist of a resin matrix and chemically bonded fillers 42 They are classified according to their
:: RDE :: Restorative Dentistry Endodontics
Dental caries is one of the most common infectious diseases in which demineralization of hard tooth tissues occurs by the acid produced as a result of fermentation of carbohydrates by bacteria 1 At present the majority of carious teeth are restored with tooth-colored restorative materials and composite resins due to esthetic reasons In fact restorations with composite resins have

Bioprinting: From Tissue and Organ Development to in Vitro
Bioprinting techniques have been flourishing in the field of biofabrication with pronounced and exponential developments in the past years Novel biomaterial inks used for the formation of bioinks have been developed allowing the manufacturing of in vitro models and implants tested preclinically with a certain degree of success Furthermore incredible advances in cell biology
Zirconia dental implants: where are we now and where are
Dec 21 2016This composite exhibits a flexural strength twice that of yttria‐stabilized tetragonal zirconia polycrystal and greater fracture toughness In addition it is less subject to low‐temperature degradation In vitro experiments demonstrate promising results in terms of cell adhesion spreading and differentiation into bone‐forming cells 29 114
In Vitro Biofilm Formation on Titanium and Zirconia
Background: It has been hypothesized that zirconia might have a reduced bacterial adhesion compared with titanium however results from experimental studies are rather controversial The aim of the present study is to compare biofilm formation on zirconia and titanium implant surfaces using an in vitro three‐species biofilm and human plaque samples

Polymerization Shrinkage and Depth of Cure of Bulk
Because composite has shown a level of success as a restorative material there have been continuous efforts to improve its physical and mechanical properties and the operating techniques used to apply it 1-3 Even so complications related to polymerization shrinkage stress and curing depth still cause significant reluctance to use them Not only will this polymerization shrinkage
