Antibacterial Activity of Endodontic Sealers against Planktonic Bacteria and Bacteria in Biofilms. -

Antibacterial activity of 4 endodontic sealers against bacteria planktonic grown or in biofilms commonly detected from persistent and secondary endodontic infections.
Investigating the antibacterial activity of endodontic sealers and materials against bacteria in biofilms is highly important to evaluate the materials’ ability to eradicate bacteria from the infected root canal

Survival of extensive restorations in primary molars: 15-year practice-based study. -

Caries decline in the western world is accompanied by strong polarization among children; 8% of Finnish 5-year-olds having 76% of untreated caries. This high caries risk group needs preventive and restorative strategies.
Severely affected primary molars of children at high caries risk are better managed, using PMCs to optimize the resources in public oral health services.

Role of Proteolytic Enzyme Inhibitors on Carious and Eroded Dentin Associated With a Universal Bonding System -

Abstract Objectives: The aim of this study was to evaluate the effect of proteolytic inhibitors on the bond strength of a universal adhesive system (etch-and-rinse mode) applied to artificial carious and eroded dentin. Methods: Ninety molars were prepared and randomly divided into three groups according to the substrate: N, no challenges; ACD, artificial carious dentin […]

Internal fit of three-unit fixed dental prostheses produced by computeraided design/computer-aided manufacturing and the lost-wax metal casting technique assessed using the triple-scan protocol -

Suboptimal adaptation of fixed dental prostheses (FDPs) can lead to technical and biological complications. It is unclear if the computer-aided design/computer-aided manufacturing (CAD/CAM) technique improves adaptation of FDPs compared with FDPs made using the lost-wax and metal casting technique.

Komposittmaterialer – utlekking av monomer og cytotoksisitet -

NIOM har på oppdrag fra Helsedirektoratet undersøkt fire komposittmaterialer: ett Own Brand Label (OBL)-materiale, to bulk-fill materialer og et mye benyttet universalmateriale. Det ble funnet ubetydelige forskjeller i utlekket monomer mellom produktene. I en cytotoksisitets-screening med ekstrakter fra produktene var det noe forskjell mellom materialene. Ytterligere molekylærbiologiske undersøkelser viste imidlertid ingen indikasjon på celleskade. Basert på disse undersøkelsene kan ingen av produktene bedømmes som mindre sikre enn de andre.
