Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Role of adjunctive methacryloyloxydecyl dihydrogen phosphate primers on dentin bond strength of universal adhesives under saliva and artificial aging

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated whether adjunctive 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) primers enhance the microtensile bond strength (µTBS) of two universal adhesives (UAs) to dentin under artificial aging and repeated salivary contamination applied at each bonding step.

Safer-by-design flame-sprayed silicon dioxide nanoparticles: the role of silanol content on ROS generation, surface activity and cytotoxicity

Particle and Fibre Toxicology, 2019
Background Amorphous silica nanoparticles (SiO2 NPs) have been regarded as relatively benign nanomaterials, however, this widely held opinion has been questioned in recent years by several reports on in vitro and in vivo toxicity. Surface chemistry, more

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.

Repair Bond Strength of Self‐Cure Bulk‐Fill Composites: Influence of Substrate Composition, Surface Conditioning, and Repair Material Type

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substrate composition, surface conditioning protocol, and repair material type on the repair shear bond strength (SBS) of an aged self‐cure bulk‐fill resin composite. Materials and Methods A total of 80 specimens were fabricated using two substrate compositions of a self‐cure bulk ...
