Light curing procedures – performance, knowledge level and safety awareness among dentists -

The study aimed to investigate dentists’ exposure to curing light and to obtain information about the dentists’ knowledge on practical use and technical features of their curing lights as well as their safety awareness.

Evaluation of material suitability for nanoparticle-based coatings and further antimicrobial treatment -

Dental materials are easily colonized by bacteria, and microbial attack is the main cause of dental implant failure and periodontitis. The aim of this project was to formulate nanoparticle-based (NPsol) coatings that reduce bacterial adherence on materials used in dentistry. Pre-treatment of the surfaces with such coatings could create a time window that allows for killing of the surrounding bacteria prior to or shortly after adhesion. One option is to apply antimicrobial photodynamic therapy (aPDT).

In vitro efficacy and risk for adverse effects of light-assisted tooth bleaching -

The use of optical radiation in the so-called light-assisted tooth bleaching procedures has been suggested to enhance the oxidizing effect of the bleaching agent, hydrogen peroxide. Documentation is scarce on the potential adverse effects of bleaching products and on optical exposure risks to eyes and skin.
