Photodynamic and Tissue Tolerable Plasma Therapies as Alternatives to Antimicrobials to Control Pathogenic Biofilms
Abstract The need for novel antimicrobial techniques has become critical for a number of reasons, including the emergence of resistant strains because of excessive prescription and misuse of antibiotics. The mouth is colonized by a large number of microorganisms. When these microorganisms are organized as biofilms they can contribute to chronic diseases in the human population, such as dental caries, candidiasis, and periodontal disease. Hence, alternative antimicrobial approaches have risen to facilitate the treatment of these diseases. As novel therapies, photodynamic antimicrobial chemotherapy and tissue-tolera...
