Use of snus, a moist, smokeless tobacco product, may lead to local changes in the oral mucous membrane in the area where the snus is placed. It can also cause irreversible gingival retraction. This cross-sectional study aimed to investigate the relationship between use of snus, oral mucosal lesions (snus induced lesions) and gingival retractions among adolescents in Norway.

Effect of Chlorhexidine digluconate on endodontic sealers

November 29th 2022

 -

A recent study showed increased antimicrobial activity of three endodontic sealers after chlorhexidine contact. Cell toxicity and physicochemical properties were mostly negatively affected.
New “Universal bonding agents” reliable for repair of composite restorations.

September 28th 2022

 -

A recent NIOM-study looked at the reliability of using “Universal bonding agents” in composite-to-composite shear bond strength test. It is worth noting that all nine bonding agents in the study performed as well, or better, than the previous “Gold Standard”, the 3-step etch-and-rinse bonding agent.
Surface characteristics and bacterial adhesion of endodontic cements

 -

Changes in the surface characteristics of prototype TCS-based cements by inclusion of SNP and BG or exposure to different environments did not affect bacterial adhesion. All experimental materials showed inferior physical properties and higher antibacterial effect than Biodentine.
