Oral lichen planus (OLP) is a common oral mucosal disease. The etiology of OLP is not clear. The treatment of OLP is difficult as some of the OLP patients have little effects to the conventional mucosal treatments. In recent years, laser therapy has been adopted to treat patients with OLP. The CO(2) laser therapy has drawn much attention of doctors and scholars because of its advantages in treating the OLP. This review article mainly discusses the principle, effects and some state-of-the-art progresses in OLP treatment using CO(2) laser.
