Photodynamic therapy – modern views and innovations in dentistry

Abstract

Photodynamic therapy (PDT) consists of three elements: a photosensitizer, light and oxygen. The photosensitizer has the property of selective accumulation in target tissues without harming healthy cells. This innovative therapeutic method has already been successfully adapted in many areas of medicine, such as dermatology, gynecology, urology and oncology. PDT is also beginning to be introduced in dentistry. The antibacterial and fungicidal properties of the photosensitizer are used to achieve better results in the medical and surgical treatment of patients. Objective. To analyze current scientifi data on the application of photodynamic therapy (PDT) in various fi of dentistry, evaluate its effectiveness, and assess prospects for development. Materials and methods. A review of recent scientifi literature was conducted, including original studies, systematic reviews, and meta-analyses focused on PDT application in dentistry. Data on mechanisms of action, clinical efficacy, and new developments in PDT were analyzed. Results. High effi of PDT was established in the treatment of periodontal diseases, peri-implantitis, endodontic infections, and oral oncological diseases. Advantages of combined application of PDT with other treatment methods were noted. Promising directions for PDT development were identifi including the creation of new photosensitizers and technological innovations in equipment. Conclusions. PDT is a promising treatment method in dentistry, demonstrating high efficacyand safety. Further research is aimed at optimizing treatment protocols, developing personalized approaches, and integrating PDT with other modern technologies.
