Photobiomodulation therapy in the treatment of a palatal ulcer

Oral mucosa is the most common site for ulcers, and severely painful ulcers of traumatic origin prompt the patient to visit an oral physician to seek necessary treatment. Currently, numerous topical analgesics and anti-inflammatory medications are prescribed to reduce pain and accelerate healing. An alternative to this is low-level laser therapy which is a drug-free and noninvasive therapy and has shown potential results in treatment of oral ulcers. In this paper, we report a case of a patient with palatal ulcer which was successfully treated using a 660-nm (red) laser.
