Laser light may replace steroids for chronic mouth pain

This study compares three treatments for painful mouth sores caused by oral lichen planus, a long-term inflammatory condition. Sixty adults will receive either a steroid cream (standard care) or one of two light-based therapies (photobiomodulation or photodynamic therapy) to see which heals sores best and reduces pain. The goal is to find a safer alternative to long-term steroid use.
