Abstract Objectives Collagen and elastin are two key structural proteins found in the extra-cellular matrices (ECMs) of most tissues, yet very little is known about the response of bone cells…

Abstract Objective The objective of this 6 year prospective randomized equivalence trial was to evaluate the long-term clinical performance of a new nano-hybrid resin composite (RC) in Class II restorations…

Abstract Objectives Secondary caries is the main reason for restoration failure, and replacement of the failed restorations accounts for 50–70% of all restorations. Antibacterial adhesives could inhibit residual bacteria in…

Abstract Objectives Currently, most titanium implant coatings are made using hydroxyapatite and a plasma spraying technique. There are however limitations associated with plasma spraying processes including poor adherence, high porosity…

Abstract Objectives (1) To measure the marginal and internal adaptation of different prosthetic crowns infrastructures (IS); (2) to analyze two types of methodologies (replica and weight technique) used to evaluate…

Abstract Objectives The phenomena occurring during zirconia frameworks veneering process are not yet fully understood. In particular the study of zirconia behavior at the interface with the veneer remains a…

Abstract Objectives The aim of the study was to evaluate the biological effects of water eluents from polycarbonate based esthetic orthodontic brackets. Methods The composite polycarbonate brackets tested were Silkon…

Abstract Aim The antibacterial activity of five endodontic sealers against three different microorganism strains alone and following incorporation of 2% benzalkonium chloride (BC) and 2% cetylpyridinium chloride (CPC) was evaluated….

Abstract Objective To investigate the influence of the convergence angle of tooth preparation on the fracture load of Y-TZP-based ceramic (YZ – Vita YZ) substructure (SB) veneered with a feldspathic…

Abstract Objectives The objective of this work is to study the crack produced by spherical and sharp indentation on veneering feldspathic dental porcelain in order to understand the morphology of…

Abstract Objectives We fabricate multi-cellular aggregates of human gingival fibroblasts (hGFs) using a novel in vivo method that omits supportive flexible substrates. On the basis of the multi-cellular aggregates, constructive…

Abstract Objectives To assess the influence of material/technique selection (direct vs. CAD/CAM inlays) for large MOD composite adhesive restorations and its effect on the crack propensity and in vitro accelerated…

Abstract Objectives The aim of this research was to evaluate the degree of monomer conversion of different resin cement shades when photocured under different feldspathic ceramic shades. The photocuring time…

Abstract Objectives To evaluate the effect of framework design modification and veneering techniques in fatigue reliability and failure modes of veneered Yttria-Stabilized Tetragonal Zirconia Polycrystals (Y-TZP) crowns. Methods A CAD-based…

Abstract Objective One of the problems encountered clinically when using mineral trioxide aggregate (MTA) as a root-end filling material is washout immediately after placement. A novel MTA is supplied with…

Abstract Objectives The purpose of this study was to evaluate the interfacial adhesion between resin and root canal dentin in the direct resin core build-up method in terms of microtensile…

Abstract Objective The aim of this study was to evaluate the void frequency ( V F ) and void volume ( V V ) in different flowable composites using swept-source…
