The significance difference among the medians was measured by the Mann–Whitney test. *Significant 0.01 < p ≤ 0.05, **Significant p ≤ 0.01
The significance difference among the percentages was measured by the Pearson Chi Square test. *Significant 0.01 < p ≤ 0.05, **Significant p ≤ 0.01
ESS Epworth sleepiness scale, K-OLP keratotic oral lichen planus, nK-OLP non-keratotic oral lichen planus, HAM-A Hamilton anxiety, HAM-D Hamilton depression, PSQI Pittsburgh sleep quality index, T-PRI Total pain rating index
