The effect of blood protein adsorption on cellular uptake of anatase TiO2 nanoparticles
Allouni, Zouhir Ekeland; Gjerdet, Nils Roar; Cimpan, Mihaela Roxana; Høl, Paul Johan (Peer reviewed; Journal article, 2015-01-19)Protein adsorption onto nanoparticles (NPs) in biological fluids has emerged as an important factor when testing biological responses to NPs, as this may influence both uptake and subsequent toxicity. The aim of the present ... -
The effect of preparation taper on the resistance to fracture of monolithic zirconia crowns
Schriwer, Christian; Gjerdet, Nils Roar; Arola, Dwayne; Øilo, Marit (Journal article; Peer reviewed, 2021)Objective Monolithic zirconia crowns have become a viable alternative to conventional layered restorations. The aim of this study was to evaluate whether the taper, and thus wall thickness, of the abutment or pre-defined ... -
Effect of saliva contamination on the bond strength of single-step and three-step adhesive systems
Bolme, June; Gjerdet, Nils Roar; Lægreid, Torgils (Journal article; Peer reviewed, 2021)The aim of this study was to evaluate the effect of saliva contamination on bond strength to dentin with an etch-and-rinse and a self-etch adhesive system. For each of these adhesive systems, the dentin surface of 24 human ... -
Fractographic analysis of 35 clinically fractured bi-layered and monolithic zirconia crowns
Skjold, Anneli; Schriwer, Christian; Gjerdet, Nils Roar; Øilo, Marit (Journal article; Peer reviewed, 2022)Objectives The aim of this retrieval study was to analyze the fracture features and identify the fracture origin of zirconia-based single crowns that failed during clinical use. Methods Thirty-five fractured single crowns ... -
Fractographic features of glass-ceramic and zirconia-based dental restorations fractured during clinical function
Øilo, Marit; Hardang, Anne Dybdahl; Ulsund, Amanda Hembre; Gjerdet, Nils Roar (Peer reviewed; Journal article, 2014-04-04)Fractures during clinical function have been reported as the major concern associated with all-ceramic dental restorations. The aim of this study was to analyze the fracture features of glass-ceramic and zirconia-based ... -
Monolithic zirconia crowns – wall thickness, surface treatment and load at fracture
Øilo, Marit; Schriwer, Christian; Flinn, Brian; Gjerdet, Nils Roar (Peer reviewed; Journal article, 2019)Purpose: The aim of this study was to evaluate the effect of wall thickness on load at fracture of monolithic zirconia dental crowns after aging. Materials and Methods: Seventy translucent monolithic zirconia crowns (DD ... -
Simulation of clinical fractures for three different all-ceramic crowns
Øilo, Marit; Kvam, Ketil; Gjerdet, Nils Roar (Peer reviewed; Journal article, 2014-04-04)Comparison of fracture strength and fracture modes of different all-ceramic crown systems is not straightforward. Established methods for reliable testing of all-ceramic crowns are not currently available. Published in-vitro ...
