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…
