Background: Oral lichen planus is a common chronic inflammatory disease of the oral mucosa with malignant potential. Topical steroids are widely used and accepted as the primary treatment of choice.The greatest disadvantage of corticosteroids is the secondary infection which develop along with the local or systemic immune suppression. Another treatment modality is Lasers. Lasers have been used indentistry since 1960. Low level laser therapy (LLLT) is widely used in the management of various inflammatory mucosal lesions. So low level laser therapy can be considered as an ideal alternative for management of recalcitrant OLP. Materials and methods: Study type is Randomized Control Trial.Atotal of 50 patients were selected. 25 patients were in the control group to whom topical steroids were given. 0.1% Triamcinolone acetonide was given thrice daily for 8 weeks for those in the control group.25 patients were in the casegroup to whom LLLT was given. Low level laser with 810 nm and 0.5 watt was used Once in a week for 8 weeks for patients in the case group. Assessment was done in the end of each week till 8th week.In the end of 12th week final assessment and follow up was done. Results: Inter group comparison of pinboonniyom scores shows that results are almost similar in two groups. There is no significant difference between both the groups. Rapidity of the response was greaterin the control group. 12th week assessment scores were similar in both the groups. VAS also shows thatthe responses were better in the control group in the initial week. In the 7th week, similar responses noted. Present randomized control trial shows a female predilection. Patients of xiii 35-50 age group ismore affected with OLP. Erosive Lichen Planus patients were prevalent more than the reticular type inthe present study. Conclusion: The present study showed that Laser provides a long-term sustained relief comparable to corticosteroids without any of its side effect. Recommendations with standardized protocol for the use of clinician, can be issued by important associations. So that it can be effectively used in themanagement of OLP.
