Abstract:Periodontal tissue infection is a chronic destructive inflammatory disease caused by bacteria including anaerobes and facultative anaerobes. Traditional mechanical debridement and antibiotic treatments are not effective at removing biofilm from the root surface, resulting in recurrent disease. Antimicrobial photodynamic therapy (aPDT) is a promising bactericidal method, but it is limited by oxygen content. Here, an oxygen‐free cationic polymer (HQRB‐SS‐Dex) containing the photosensitizer rose bengal (RB) and d… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
