Conventional therapies, such as corticosteroids, are often associated with side effects, prompting the exploration of alternative treatments. High-power lasers, including CO2 and Er:YAG lasers, have emerged as promising options due to their precision and therapeutic potential in managing OLP. This systematic review aimed to evaluate the effectiveness of high-power lasers in reducing lesion size, pain, and recurrence rates in OLP patients. Methods: A comprehensive search was conducted in databases such as PubMed, Scopus, Embase and Cochrane using keywords related to laser therapy and OLP. Inclusion criteria focused on randomized controlled trials and clinical studies with clear methodologies. Data from eight studies were analyzed, covering various laser types and treatment parameters. Results: The findings indicate that high-power laser therapy significantly reduces lesion size, pain levels, and recurrence rates compared to conventional treatments. CO2 lasers demonstrated superior outcomes in lesion resolution and pain relief, while Er:YAG lasers offered precision in treating localized lesions. Most studies reported minimal side effects and faster recovery times, enhancing patient satisfaction. Conclusions: High-power lasers, particularly CO2 and Er:YAG, represent a safe and effective alternative to conventional therapies for OLP, with advantages such as reduced side effects and improved patient outcomes. Future research should focus on standardizing protocols and conducting large-scale randomized trials to validate these findings and establish lasers as a reliable treatment modality for OLP.<\/jats:p>","DOI":"10.3390\/jcm15031084","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T08:19:38Z","timestamp":1769761178000},"page":"1084","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["High-Power Laser Therapy for Oral Lichen Planus: A Systematic Review"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-3173-9389","authenticated-orcid":false,"given":"Jakub","family":"Fiegler-Rudol","sequence":"first","affiliation":[{"name":"Department of Periodontal Diseases and Oral Mucosa Diseases, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0172-0571","authenticated-orcid":false,"given":"Wojciech","family":"Niemczyk","sequence":"additional","affiliation":[{"name":"Department of Periodontal Diseases and Oral Mucosa Diseases, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-055 Katowice, Poland"},{"name":"Department of Oral Surgery, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3801-0218","authenticated-orcid":false,"given":"Jacek","family":"Matys","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2353-3198","authenticated-orcid":false,"given":"Jakub","family":"Hadzik","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8732-251X","authenticated-orcid":false,"given":"Dariusz","family":"Skaba","sequence":"additional","affiliation":[{"name":"Department of Periodontal Diseases and Oral Mucosa Diseases, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5673-7413","authenticated-orcid":false,"given":"Rafa\u0142","family":"Wiench","sequence":"additional","affiliation":[{"name":"Department of Periodontal Diseases and Oral Mucosa Diseases, Faculty of Medical Sciences in Zabrze, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8943-0549","authenticated-orcid":false,"given":"Marzena","family":"Dominiak","sequence":"additional","affiliation":[{"name":"Dental Surgery Department Faculty of Dentistry, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"ref_1","unstructured":"Raj, G., and Raj, M.
