Photodynamic therapy (PDT), also known as photo-radiation therapy, phototherapy, or photo-chemotherapy, involves the use of a photoactive dye (photosensitizer) that is activated by exposure to light of a specific wavelength in the presence of oxygen. The transfer of energy from the activated photosensitizer to available oxygen results in the formation of toxic oxygen species, such as singlet oxygen and free radicals. Applications of PDT in dentistry are growing rapidly: the treatment of oral cancer, bacterial and fungal infection therapies, and the photodynamic diagnosis (PDD) of the malignant transformation of oral lesions.PDT has shown. potential in the treatment of oral leukoplakia, oral lichen planus, and head and neck cancer.
