This study aimed to investigate the effects of (i) a high-irradiance (3s) light-curing protocol versus (ii) two standard-irradiance (10s) protocols on 2D temperature maps during intra-dental photo-irradiation within molar cavity restored with either Ultra-Rapid Photo-Polymerized Bulk Fill (URPBF) composites or pre-heated thermo-viscous bulk-fill composite, compared standard resin-based-composit...

AIM The aim was to perform comparative analysis of bioactive, contemporary bulk-fill resin-based composites (RBCs) and conventional glass-ionomer materials for flexural strength (FS), diametral tensile strength (DTS), and Vickers hardness number (VHN) in the presence of thermocycling. MATERIALS AND METHODS Five restorative materials [Tetric N-Ceram Bulk Fill; smart dentin replacement (SDR) Fl...

This review purports to fill the gap in knowledge that exists about the role of nanoparticles in Tissue Engineering. In this review, the use of the term nanoparticles will be exclusively confined to those materials or composites with grain sizes ranging from 100-500 nm. First, a brief description of the field will be provided. Next, research findings on the use of cells on ceramics, peptides, c...

Montmorillonite (MMT) clay mineral is widely used as filler for several organic coatings. Its activity is increased by exfoliation via chemical modification to produce nanomaterials. In the present work, the modification of MMT to form nanogel composites is proposed to increase the dispersion of MMT into epoxy matrices used to fill cracks and holes produced by the curing exotherms of epoxy resi...

PURPOSE The aim of this study was to evaluate the effects of 4 mouth rinses on the color stability of two different resin composites. MATERIALS AND METHODS A2 shade sonic-activated bulk fill material SonicFill (Kerr) and conventional nanohybrid composite Filtek Z550 (3M ESPE) were used. Forty disc-shaped specimens (10 mm x 2 mm) were fabricated for both composites and finished using 400-grit ...
