The purpose of this study is to assess the effectiveness of C02 laser in relieving symptoms associated with Oral lichen planus (aLP) and lichenoid lesions (aLL) and the event of healing. Six patients were selected for this study with 13 sites treated. Each lesion was ablated with C02 laser and the wound allowed to heal undisturbed. Prior to treatment, 4 patients had both unprovoked and provoked pain and 2 patients rated for provoked pain only. After laser ablation, five out of six patients treated recorded no pain / 0 pain score. One month post-laser, the treated area was almost the same colour as the surrounding normal mucosa and soft in texture in all but one patient in which there was some fibrosis and residual plaque-like patch. Weconclude that the use of C02 laser in the treatment of aLP and aLL shows positive results in relieving symptoms associated with these lesions.
