Lasers (Light Amplification by Stimulated Emission of Radiation) are advanced tools used in oral medicine for both diagnostic and therapeutic purposes. They offer benefits such as precision, minimal bleeding, reduced pain, and faster healing. Common applications in oral medicine include the treatment of aphthous ulcers, oral lichen planus, leukoplakia, and fibromas. Lasers are also used in biopsy procedures, depigmentation, and photobiomodulation therapy for pain and inflammation control. Their minimally invasive nature makes them a valuable adjunct in modern dental and oral healthcare.
