Lethal photosensitization of periodontal pathogens by a red‐filtered Xenon lamp <i>in vitro</i>

Abstract

The data indicate that PDT utilizing a conventional light source is at least as effective as laser-induced treatment in vitro. Furthermore, PDT achieves significant bactericidal activity in the presence of serum and blood when used with the set parameters of 10 J/cm2, 100 mW/cm2 and 12.5 micro g/ml TBO.
