Investigation on the antimicrobial activity of chitosan-modified zinc oxide-eugenol cement -

The present study showed that a ZOE-based material has an antibacterial effect and that incorporating CH or COS may increase the antibacterial effect depending on the bacterial species. The total release of eugenol from the materials was stable for up to 18 weeks immersion in water. Eugenol therefore contributed to the antibacterial effect on all the material surfaces investigated. S. mutans exhibited the highest susceptibility to eugenol. The compressive strength of the modified materials was reduced but still met the requirements in ISO 3017.

Digital dentistry -

Digital manufacturing using intraoral scanners appears to provide equivalent fit compared to conventional technique for smaller prosthetic constructions. Milled composites have a less toxic potential compared to traditional light cured directly placed composite restorations.

NIOM with strong contingent at the ISO/TC 106 annual meeting in Milan -

At the annual dentistry standardisation meeting being held in Milan, Italy from September 16 to 21 there will be a strong NIOM contingent.

Preparation and characterization of Bis-GMA-free dental composites with dimethacrylate monomer derived from 9,9-Bis[4-(2-hydroxyethoxy)phenyl]fluorene. -

New dimethacrylate monomer Bis-EFMA was synthesized and used to prepare Bis-GMA-free dental resin and composite materials. Studies of the experimental materials showed that Bis-EFMA-based resin matrix and composite materials had improved properties compared to Bis-GMA-based resin matrix and composite materials, respectively. Compared with the commercial dental composite material Z250, Bis-EFMA-based composite showed similar or improved properties except for a lower FS after water immersion. Based on the presented results, Bis-EFMA has potential to be used in commercial dental composites.

Shining new light on dental biomaterials: NIOM is hosting Northern Lights 2018 -

NIOM is host and local organizer of the sixth annual Northern Lights International Symposium which is taking place July 30-31st in Oslo. The main topics of the conference are bioactive materials and light transmission through ceramics and composites. The symposium aims to bring together almost 60 leading experts from 16 countries and over two days they will work through the topics through presentations and discussions, leading to a consensus that will be covered in a wide variety of post-conference publications.
