The efficacy of antimicrobial photodynamic therapy, using various distinct photosensitizers, has been studied since the 1990s. [ 9 ] [ 7 ] Most studies have yielded positive outcomes, often achieving disinfection levels, as defined by infection control guidelines, exceeding 5 log 10 (99.999%) of microbial inactivation. [ 14 ]
Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [ 1 ] PDT is used in treating acne , wet age-related macular degeneration , psoriasis , and herpes .
Dental infections tend to also respond better to photothermal therapy than photodynamic therapy, though both have a strong effect. [ 10 ] [ 11 ] [ 12 ] The efficacy of PDT for antimicrobial usage is limited by the properties of the membrane of the target cell such as the electrical gradient ( membrane potential ) and lipid composition.
Photodynamic therapy (PDT) is a form of phototherapy using nontoxic light-sensitive compounds (photosensitizers) that are exposed selectively to light at a controlled wavelength, laser intensity, and irradiation time, whereupon they generate toxic reactive oxygen species (ROS) that target malignant and other diseased cells.
PDT: photodynamic therapy: PDVT: postoperative deep-vein thrombosis PE: pulmonary embolism [1] pre-eclampsia pleural effusion physical examination [1] PEA: pulseless electrical activity: PERRLA: pupils equal, round and reactive to light [3] PEB: cisplatin, etoposide, and bleomycin (chemotherapy regimen) PEEP: positive end-expiratory pressure ...
The Santa Ynez Reservoir, a 117-million-gallon water resource near the Pacific Palisades, was under renovation and empty when fires tore through the Los Angeles neighborhood last week and ...

Photodynamic therapy (PDT) has proven to be an effective approach for AK at sites of poor healing with few responses to other therapies. [32] In the comparison study between MAL-LEDT and typical cryotherapy, blue-light LEDT with Aminolevulinic acid (ALA) as a photosensitizer reveals significantly higher healing rates.
