Abstract Objectives The aim of this study was to investigate the influence of shrinkage strain, modulus, and instrument compliance on the polymerization shrinkage stress measurement of light-cured composites, and to…
Abstract Objectives The aim is to demonstrate significant polymerization shrinkage stress reduction in model resins through incorporation of addition–fragmentation chain transfer moieties that promote network stress accommodation by molecular rearrangement….
Abstract Objectives The aim of this study was to evaluate the cytotoxic effect of the monomers isobutyl methacrylate (IBMA) and 1,6-hexanediol dimethacrylate (1,6-HDMA), the plasticizer di- n -butyl phthalate (DBP),…
Abstract Objectives This study aimed to investigate the durability of four adhesive luting systems bonded to dentin with and without simulated hydrostatic pulpal pressure (PP). Methods Composite blocks were bonded…
Abstract Objectives To carry out a meta-analysis in order to assess the influencing factors on retention loss and marginal discoloration of cervical restorations made of composites and glass ionomer (derivates)….
Abstract The effect of ageing in phosphate-containing solution of bioactive calcium-silicate cements on the chemistry, morphology and topography of the surface, as well as on in vitro human marrow stromal…
Abstract Objectives To characterize the properties of dentin matrix treated with two proanthocyanidin rich cross-linking agents and their effect on dentin bonded interfaces. Methods Sound human molars were cut into…
Abstract Objective To investigate the potential application of bilateral treatment of glazing plus staining in machinable veneer mechanical strength improvement. Methods Standard laminate specimens ( n = 105) were sliced…
Abstract Objectives The purpose of this clinical study was to evaluate the long-term outcome of three-unit posterior fixed partial dentures (FPDs) made of fiber-reinforced resin composite (FRC), and to identify…
Abstract Objectives The contraction stress of a silorane-based material and a new low-shrinkage nanohybrid composite were compared to three conventional dimethacrylate-based resin composites using two different measuring systems. It was…
Abstract Objectives Secondary caries and restorative fracture are the two main reasons for restoration failures. Fluoride ion (F) release can help inhibit caries. Plaque pH after a sucrose rinse can…
Abstract Objectives To evaluate marginal integrity of direct resin composite restorations before and after thermo-mechanical loading in vitro , and before and after 6 years of clinical service in a…
Abstract Objectives The change in optical characteristics through the bulk of curing photopolymers is not fully understood. Photopolymerization processes are accompanied by photoinitiator absorption, density changes and volumetric shrinkage, which…
Abstract Objectives Optical properties of an object are determined visually or instrumentally. Although instrumental measurement provides objective and quantitative color coordinates, these values vary by the measurement method such as…
Abstract Objectives Type I collagen alone cannot initiate tissue mineralization. Sodium trimetaphosphate (STMP) is frequently employed as a chemical phosphorylating reagent in the food industry. This study examined the feasibility…
Abstract Objectives To evaluate the translucency, opalescence and light transmission characteristics of resin composites with different thicknesses. Methods Disks of three resin composites (Estelite∑, Beautifil II, Clearfil Majesty) of A2…
Abstract A static bond-strength test is often regarded as clinically less relevant, since such abrupt loading of the adhesive-tooth bond clinically never occurs. Therefore, dynamic fatigue testing is often claimed…
Abstract The progressive degradation of resin–dentin bonds is due, in part, to the slow degradation of collagen fibrils in the hybrid layer by endogenous matrix metalloproteinases (MMPs) of the dentin…
Abstract Objectives Color coordinates of translucent esthetic materials measured by traditional spectrophotometers (SP) would deviate from those measured by newly introduced spectroradiometers (SR), which might simulate the clinical viewing condition…
Abstract Objectives Osteogenesis on titanium (Ti) surfaces is a complex process involving cell–substrate and cell–cell interaction of osteoblasts and endothelial cells. The aim of this study was to investigate the…
