Antimicrobial effect of photodynamic therapy using high‐power blue light‐emitting diode and red‐dye agent on <i>Porphyromonas gingivalis</i>

Abstract

Within the limits of this study, BL was found to have an antimicrobial/growth-inhibiting effect on P. gingivalis, and a-PDT using a combination of BL and RB shows promise as a new technical modality for bacterial elimination in periodontal therapy.
