Abstract

Introduction: Erosive, atrophic Oral lichen planus (OLP) is a chronic painful disorder with some degrees of susceptibility to malignancy. However, there is no definite treatment for this lesion.Aim: To evaluate the effectiveness of low intensity laser in treatment of erosive-atrophic OLP lesions.

Materials & Methods: 28 patients with erosive-atrophic OLP treated with a 630-nm diode laser (Mustang 2000+, Russia, KLO3 probe, 10 mw, continuous wave, spot size: 1×1 cm). Subjects underwent 5 minutes irra-diation with the intensity of 3 J/cm² per session every 3 days for 3 weeks. Response rate was evaluated based on the pre-treatment and post-treatment appearance score (Severity of the lesions) and pain score (Visual Analogue Scale) of the lesions.

Results: The mean VAS healing rates were 82.4 ±11.5%, 78.8±11.3%, and 77.7±13.3% just after treatment, 6 months and 12 months after treatment respectively. The mean severity healing at the mentioned periods were 92.9±15.7%, 61.2±29.3%, and 46.0±28.7% respectively. VAS scores were decreased significantly (p-value=0.000) after treatment and didn’t relapse after 6 and 12 months (p > 0.05). Severity of the lesions decreased significantly after treatment but relapsed within 6 and 12 months.

Conclusion: Our study demonstrated a relative effectiveness of low intensity laser therapy in treatment of OLP lesions.
