A recent study showed increased antimicrobial activity of three endodontic sealers after chlorhexidine contact. Cell toxicity and physicochemical properties were mostly negatively affected.

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.

Killing off bacteria by using light on a thin film covering, sounds intriguing to say the least. The possibilities would be endless, from restorations to self-cleaning environmental surfaces, and on. A collaborative team from NIOM and the University of Oslo (UiO) is currently making strides in this direction.
