Periodontal Initial Treatment Combined With Glucocorticoid Therapy for Erosive Oral Lichen Planus

The purpose of this clinical trial is to understand whether the combination of periodontal initial treatment under local anesthesia and glucocorticoids can improve the effectiveness of treatment for erosive oral lichen planus. It will also understand the safety of this treatment regimen. This study is a single-center, parallel-group, randomized self-controlled trial. The researchers will compare the treatment of periodontal initial therapy combined with glucocorticoid therapy under local anesthesia with traditional glucocorticoid therapy to see if the treatment of periodontal initial therapy combined with glucocorticoid therapy under local anesthesia promotes the healing of erosive oral lichen planus. Participants will: One side received periodontal initial treatment combined with glucocorticoid under local anesthesia, while the other side received traditional glucocorticoid therapy Clinical examination at 2, 4, 8, and 12 weeks after treatment Note down the size of their erosion lesion area and periodontal clinical parameters
