3D printing in odontology -

Those who were able to attend the last IDF trade fair in Cologne, the year before the pandemic, saw 3D printers everywhere. There has been a steady growth in the use of 3D printing to produce resin-based appliances. In order to clarify the various 3D methods, NIOM’s Ida Stenhagen has written a review article.

How to talk to fluoride sceptics -

As recent news articles highlight the dangers of ski wax containing fluorinated compounds, more patients are becoming skeptical towards fluoride in toothpaste. It is vital to be clear that these are two completely different forms of fluorine element with respect to both toxicity and reactivity.

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.

How can dental materials be made better? -

Future resin-based dental materials must combat the reasons current materials fail, mainly secondary caries and fracture, but still be easy for the dentist to use and safe for the patient.
