Summary

Photodynamic therapy (PDT) is a technique used for the oral disinfection. In dentistry, PDT for microbial inactivation may reduces both dental plaque and risk of developing caries as well as contributes to treat gingivitis, periodontitis, peri-implantitis and endodontic diseases. The investigators hypothesis was that PDT with blue light and curcumin promotes oral disinfection during 2 hours after treatment.
