Antimicrobial photodynamic therapy against clinical isolates of carbapenem-susceptible and carbapenem-resistant Acinetobacter baumannii
(2019-01-01)
Infections caused by Acinetobacter baumannii have become a challenge for healthcare professionals because of the rapid increase in Gram-negative bacteria resistant to carbapenem antibiotics. The objective of this study was ...
A randomized clinical trial evaluating Photodithazine-mediated Antimicrobial Photodynamic Therapy as a treatment for Denture stomatitis
(2020-12-01)
Objective: This randomized clinical trial assessed antimicrobial Photodynamic Therapy (aPDT) mediated by Photodithazine (PDZ) to treat patients with denture stomatitis (DS). Methodologies: Patients with DS were randomly ...
Antimicrobial effects of photodynamic therapy with Fotoenticine on Streptococcus mutans isolated from dental caries
(2021-06-01)
Photodynamic therapy (PDT) is a promising strategy to control cariogenic pathogens, such as Streptococcus mutans. Seeking to reach the total bacterial elimination from dental surfaces, novel photosensitizers have been ...
Photodynamic inactivation using a chlorin-based photosensitizer with blue or red-light irradiation against single-species biofilms related to periodontitis
(2020-09-01)
Chlorin-e6 (Ce6), as a photosensitizer (PS), has demonstrated significant reduction of microorganisms’ viability when irradiated by red light. However, the main absorption peak of this PS is located at blue light spectrum, ...
Conjugation of superparamagnetic iron oxide nanoparticles and curcumin photosensitizer to assist in photodynamic therapy
(2020-12-01)
In this work, we describe the synthesis and characterization of the SPIONP-CUR conjugate between curcumin (CUR) and superparamagnetic iron oxide nanoparticles (SPIONPs), in addition to its application in photodynamic therapy ...
