<abstract xmlns="http://www.w3.org/1999/xhtml"> In our research, we determine the effect of low-level laser irradiation with nanoparticles on Streptococcus salivarius. Photodynamic killing of periodontopathogenic bacteria may be an alternative to the systemic application of antibacterial drugs used in the treatment of periodontal diseases. The application of photosensitizing nanoparticles and their excitation by visible light of blue spectra enables effective killing of periodontopathogens. This data combined with the results demonstrates that TiO2, AgTiO2 and S/TiO2 can inhibit the proliferation of Streptococcus salivarius due to its high photocatalytic activity, which irreversibly damages the cell walls and membranes.</abstract>
