Over the last 20 years, the number of pathogenic multi-resistant microorganisms has grown steadily, which has stimulated the search for new strategies to combat antimicrobial resistance. Antimicrobial photodynamic therapy (aPDT), also called photodynamic inactivation, is emerging as a promising alternative to treatments based on conventional antibiotics. We have explored the effectiveness of me...
Background and Objective: The treatment of cancer comes as a great challenge worldwide. Thus the development of effective therapies with minimal side effects is important. Photodynamic therapy is a non-invasive and new therapeutic approach for the treatment of cancer. Therefore, in this study, we evaluated the photodynamic effects of a light-sensitive compound, Zinc-phthalocyanine (ZnPc), on ce...
A 41-year-old male with a dental history of invasive cervical resorption (ICR) was initially treated surgical endodontics approach and secondly antimicrobial photodynamic therapy (aPDT) along endodontic retreatment. The use aPDT essential to promote bacterial reduction in the defect. Combining these techniques allowed for clinical, radiographic, tomographic success after five years follow-up.
Objective: The aim of this in vitro study was to compare the antimicrobial effects of photodynamic antimicrobial chemotherapy (PACT), an ordinary antiseptic (chlorhexidini digluconas), and an antibiotic therapy (bacitracinum zincicum and neomycini sulfas) in vitro. Background: Photodynamic therapy (PDT) is an area of great interest for its potential use as an antimicrobial therapy. It is curren...
The oral cavity is colonized by a large number and highly diversified communities of micro-organisms. Bacterial biofilm present on tooth or root surface is a major cause of gingivitis and periodontitis. Chemical antimicrobial agents are widely used in prophylactic and therapeutic regimens for dental plaque related diseases, which are among the most common human infections. As these agents are d...
We review the recent literature concerning the efficiency of antimicrobial photodynamic inactivation toward various microbial species in planktonic and biofilm cultures. The review is mainly focused on biofilm-growing microrganisms because this form of growth poses a threat to chronically infected or immunocompromised patients and is difficult to eradicate from medical devices. We discuss the b...
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 faecalis (ATCC 29212). MATERIALS AND METHODS The uptake and distribution of nanoparticles in E. faecalis in suspension was investigated by transmission electron microscopy (TEM) after incubation with PLGA complexed wit...
