Lichen Planus is a relatively common mucocutaneous disease which usually affects the oral mucosa. Patients with Oral Lichen Planus (OLP) suffer from symptoms that affect different aspects of their daily life. Although the exact etiology of OLP is unclear، the role of psychological disorders especially stress، anxiety and depression is debated. The aim of this study was to analyze mental health and oral health related quality of life in patients with OLP. In this case-control study، 35 patients with OLP along with 50 healthy people matched by age، sex and oral health level were involved. Both groups completed the GHQ-28 and OHIP-14 questionnaires. Oral examination was also performed. At the end، data were analyzed by SPSS v. 18 software and Descriptive statistics، Chi Square Test، T-test and Mann-U- Whitney Test. There were statistically significant differences in the functional limitation and physical disability aspects of OHIP-14 in patients with OLP in comparison with the normal group (P =0/02(P= 0/03) respectively. Besides، there were no significant differences between the groups with respect to psychological disorders. (P = 0/41) The quality of life in patients with OLP is reduced in some aspects. Moreover، our findings do not support a relation between OLP and psychological disorders.
