Antimicrobial effect of blue light using Porphyromonas gingivalis pigment.
Yoshida A, Sasaki H, Toyama T, Araki M, Fujioka J, Tsukiyama K, Hamada N, Yoshino F. Yoshida A, et al. Sci Rep. 2017 Jul 12;7(1):5225. doi: 10.1038/s41598-017-05706-1. Sci Rep. 2017. PMID: 28701797 Free PMC article.
In this study, we performed aPDT using protoporphyrin IX (PpIX), an intracellular pigment of P. gingivalis, without an external photosensitizer. We confirmed singlet oxygen generation by PpIX in a blue-light irradiation intensity-dependent manner. We d …
