Nanofillers in resin materials can improve their mechanical and physicochemical properties. The present work investigated the effects of zirconia nanoparticles (NPs) as fillers commercial dental luting cements. Two dual-cured self-adhesive composites one modified glass ionomer (RMGI) cement were employed. Film thickness (FT), flexural strength (FS), water sorption (Wsp), shear bond (SBS) to monolithic evaluated according ISO 16506:2017 9917-2:2017, whereas polymerization progress was with...
Purpose To evaluate the effects on surface properties (morphology, roughness, microhardness, composition) and bond strength to composite of four types base cements (Equia-Fil/EQF, Angelus white MTA/MTA, Biodentin/BDN IRM/IRM) when treated with phosphoric acid etching (PAE) or two self-etch adhesives (Select One Prime & Bond Clearfil S3 Bond). Materials methods Disk-shaped specimens were prepared stored until complete setting. The surfaces before after treatments examined by stereomicroscopy,...
The purpose of the study was investigation polymerization a preheated composite resin beneath lithium disilicate. First, disilicate discs in two shades (HT A2 and HT A4) three different thicknesses (2, 4, 6 mm) were bonded on dentine with that photo-polymerized for 20 s. microhardness, double bond conversion (DC) their correlation estimated. Second, standardized occlusal veneers (4 photopolymerized 60 or 270 A microhardness line profiling performed cross-section each specimen correspondence...
Abstract Objectives The aim of the study was to evaluate mineralization and resin bonding capacity coronal secondary dentine at various ages. Materials Methods mineral matrix ratio (M) mandibular incisor sections classified in three age groups (I:21-40y/n=7, II: 41-60y/n=5, III: 61-80y/n=7) were measured by Fourier transform infrared microscopy (FTIRM), incisal (MC) pulpal (MP) primary (MR). Then, difference between MC-MP normalized corresponding MR calculated (NM) per specimen. a composite...
