Abstract
The aim of the study was to assess the impact of laser irradiation during antimicrobial photodynamic therapy. Test chambers containing each a salivary pellicle layer and a Stretococcus mutans culture were analyzed using confocal laser microscopy after adding a photosensitizer. Half of the chambers were irradiated with a diode laser. Comparing baseline fluorescence with the values after laser irradiation, a decrease of fluorescence could be observed. The non-irradiated group showed a slight increase of fluorescence. The present study indicates that laser irradiation is an essential part to reduce bacteria by antimicrobial photodynamic therapy.
