The aims of this study were to investigate the effects of photodynamic therapy (PDT) on
endodontic pathogens in planktonic phase as well as on Enterococcus faecalis biofilms in …

Microbial biofilms in the oral cavity are involved in the etiology of various oral conditions,
including caries, periodontal and endodontic diseases, oral malodor, denture stomatitis, …

This study explores a new approach for antimicrobial therapy with light activation of targeted
poly-l-lysine (pL)–chlorine6 (c e6 ) conjugates. The goal was to test the hypothesis that …

We investigated the photodynamic effects of methylene blue on multispecies root canal
biofilms comprising Actinomyces israelii, Fusobacterium nucleatum subspecies nucleatum, …

OBJECTIVE: To study the in vitro effects of poly(lactic-co-glycolic acid) (PLGA) nanoparticles
loaded with the photosensitizer methylene blue (MB) and light against Enterococcus …

Background and Objective Some oral bacteria are susceptible to killing by red light after their
sensitization with toluidine blue O (TBO). The photochemotherapy of periodontal disease in …

We have found that broadband light (380 to 520 nm) rapidly and selectively kills oral black-pigmented
bacteria (BPB) in pure cultures and in dental plaque samples obtained from …

Background and Objectives We previously reported the use of a flexible fiber optic that uniformly
distributed light in the root canal space for targeting bacteria after their sensitization with …

INTRODUCTION: The objective of this study was to evaluate the antimicrobial effects of
photodynamic therapy (PDT) on infected human teeth ex vivo. METHODS: Fifty-two freshly …

Background and Objectives Periodontal disease results from the accumulation of subgingival
bacterial biofilms on tooth surfaces. There is reduced susceptibility of these biofilms to …
