Primary outcome1.1. Pain measurement using the Visual Analogue Scale: according to Maxwell [All patients were asked to define their level of pain and discomfort by using a numerical rating from 0 to 10 (11-points), with 0 indicating "no pain", 1 to 3 indicating mild pain, 4 to 6 indicating moderate pain, 7 to 9 indicating sever pain and 10 indicating "extremely painful".1.2. Clinical improvement of the lesion, according to Thongprasom et al. [ 0 = no lesion 1 = white striae only2  = white striae and atrophic ≤ 1 cm3  = white striae with atrophic > 1 cm 4 = white striae with erosion ≤ 1 cm 5 = white striae with erosion > 1 cmThe clinical score for each patient was calculated by recording a score for each lesion in the oral cavity separately using a graduated periodontal probe, and then calculating the average of these scores.Secondary outcome2.1. Change in salivary level of malondialdehyde detected at baseline and after treatment (after 4 weeks) using ELISA.2.2. Change in Clinical global impression scale detected from baseline to the end of treatment after 4 weeks, in which the patients rated overall change in OLP symptoms during the treatment period (patient global impression of change; PGI-C), choosing 1 of 7 answers ranging from “very much better” to “very much worse.” 1 = very much better/improved, 2 = much better/improved, 3 = a little better/improved, 4 = no change, 5 = a little worse, 6 = much worse, and 7 = very much worse.
