Abstract Introduction The hypothesis was that experimental ion-leaching bioactive composites enhance remineralization of apatite-depleted dentin. Materials and methods Calcium-aluminosilicate (wTC-Ba) or fluoride-containing calcium-aluminosilicate (FTC-Ba) Portland-derived mineral powders were mixed with…
Abstract Objectives To analyze marginal integrity of resin composites dental restorations using optical coherence tomography (OCT). Methods Thirty extracted human premolars had occlusal cavities prepared and were randomly divided according…
Abstract Objectives To develop an enhanced, reproducible and discriminatory biocompatibility testing model for non-precious dental casting alloys, prepared to a clinically relevant surface finishing condition, using TR146 oral keratinocyte cells….
Abstract Objective Chipping failures observed clinically in bilayer systems of porcelain and zirconia restorations should be coupled with a monoclinic to tetragonal phase transformation in the zirconia layer due to…
Abstract Objectives The aim was to evaluate the stress distribution, comparing an anterior sound tooth with post-endodontic restored teeth under mechanical loading. Methods A three-dimensional finite element analysis was performed…
Abstract Objectives CAD/CAM-technologies aim for a standardized, accurate production of dental restorations out of high strength materials (zirconia). The three-dimensional internal fit of CAD/CAM-manufactured zirconia copings was evaluated in vitro…
Abstract Objectives Chewing simulators are used for preclinical evaluation of newly developed dental restorative materials. To guarantee the independence of test conditions, contact forces during chewing simulation should be independent…
Abstract Objectives The purpose of this study was to evaluate the cantilever-bending test as a bond-strength measurement method for enamel/composite adhesion. Materials and methods The buccal surface of bovine incisors…
Abstract Objective To evaluate the effect of the specimen design on the flexural strength ( σ f ) and failure mode of ceramic structures, testing the hypothesis that the ceramic…
Abstract Objectives Surface conditions are of interest in all-ceramic restorations since they can control both bonding and strength. Tensile testing methods are commonly used to evaluate surface conditions of ceramics….
