Previous studies have shown one of the causative agents of periodontitis, Porphyromonas gingivalis, can be killed by red light in the presence of the light-activated antimicrobial agent toluidine blue O (TBO). The purpose of this study was to determine the effects of irradiating the organism with red light in the presence of TBO on its proteolytic enzyme activity. Suspensions of P. gingivalis were exposed to light with a wavelength of 633 nm in the presence of various concentrations of TBO… CONTINUE READING
