• Dentists now have access to a wide range of unique treatment methods as a result of substantial scientific and technological breakthroughs in the field of dentistry. Photodynamic therapy (PDT) is a non-invasive treatment procedure that use photosensitizers, a specific wavelength of light, and the production of singlet oxygen and reactive oxygen species (ROS) to kill undesired eukaryotic cells (such as oral tumors) and harmful microbes. In several disciplines of dentistry, it is seen as a valid therapeutic option. The purpose of this study was to examine the effectiveness and side effects of PDT in the treatment of oral premalignant lesions.

  Three search engines (PubMed, ISI Web of Science, and the Cochrane Library) were used to conduct a systematic review using the phrases photodynamic therapy and PDT in combination with other terms. To define our study eligibility criteria, we used the Population, Intervention and Comparison, Outcomes, and Study design technique.

  Initial results were 33. Definitely, 18 studies met our selection criteria.

  Our analysis suggests ALA- PDT as a promising therapeutic modality for OEL lesions which should be treated first with the topical ALA-PDT using either the LED or laser light for successful clinical outcome for OEL lesions.
