The aim of this study was to investigate the antibacterial and antibiofilm properties of low viscosity chitosan on S. epidermidis growth and biofilm formation.

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).
Chitosan – antibacterial use in dental materials

Secondary caries is the primary reason for replacement of composite fillings, and clinical studies report more secondary caries when composites are used compared to amalgam in high-risk caries groups. This highlights the need for development of materials that will reduce or inhibit biofilm formation on dental materials.
Techniques for studying biofilm

The oral cavity is one of the human habitats with the highest diversity of bacterial species. It is estimated to be over 700 bacterial species that are capable of residing in this habitat. Bacteria were long thought of living as free floating, planktonic cells. However, it has become clear that the preferred form of living is in a biofilm.
