Oral lichen planus (OLP) occurs in from 2% to 3% of the population and may have a risk of malignant transformation into squamous cell carcinoma (SCC). This risk is not necessarily associated with exposure to tobacco and alcohol. An increased awareness of a possible role of human papilloma virus (HPV) and SCC led us to review a possible association between this virus infection and malignant tran...

Lichen planus (LP) is a chronic inflammatory disease of probable immune-based etiology. The pathogenesis of LP is unclear, but apoptotic changes in epidermal (epithelial) cells have been reported. Destruction of the basal cell layer is observed and many changes in cell proliferation, cell repair and cell death occur in the injured mucosal epithelium. The aim of this study was to evaluate and co...

OBJECTIVE This investigation was conducted to determine the possible association between oral lichen planus (OLP) and hepatitis C virus infection (HCV) in the population of São Paulo (Brazil). MATERIALS AND METHODS Three groups of patients were studied: group 1 was composed of 68 patients with OLP lesions; group 2 had 126 patients with HCV infection; and the control group consisted of 898 ind...

BACKGROUND The association between hepatitis C virus (HCV) infection and oral lichen planus (OLP) has been the focus of many studies. Fifteen percent of HCV infections lead to sets of extrahepatic manifestations including lichen planus (LP). The prevalence of HCV is heavily influenced by geographical location. OBJECTIVES This study aimed to evaluate the relationship between OLP and HCV infect...

BACKGROUND The aim of this study was to evaluate the efficacy of a topical hyaluronic acid (HA) gel preparation (0.2%) in the management of oral lichen planus (OLP). METHODS A total of 124 patients with erosive OLP participated in a randomized, placebo-controlled, double-blind trial to evaluate the efficacy of a topical HA preparation. Outcome measures included soreness relief following immed...

conclusions our investigation illustrated that the prevalence of hepatitis c was higher among olp patients compared to the control group. these findings are in line with previous results that reported a hepatitis c prevalence of 0.19% among the general population of mashhad. results of the 134 olp patients only three (2.23 %) had hcv infection where both anti-hcv and hcv-rna were positive. all ...

BACKGROUND AND AIMS The role of cytokines in the immunopathogenesis of oral lichen planus (OLP) has received much attention. The aim of this study was to evaluate the serum levels of TNF-α and TGF-β in patients with OLP in an Iranian population. MATERIALS AND METHODS Thirty-two patients with OLP and 32 age-matched healthy volunteers as a control group were included in this study. Serum tests ...

STATEMENT OF PROBLEM Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease with indefinite etiology. In recent researches, free radicals have been deliberated as the possible etiology of inflammatory and autoimmune diseases. PURPOSE This study was aimed to evaluate the stress oxidative status with the nitric oxide (NO) index in a sample of Iranian population. MATERIALS AND...

Lichen planus is a chronic inflammatory mucocutaneous disease. Mucosal lesions are classified into six clinical forms and there is malignant potential for two forms of OLP; therefore, follow-up should be considered. There are many un-established etiological factors for OLP and some different treatment modalities are based on etiology. The aims of current OLP therapy are to eliminate mucosal ery...

The objective of this study was to determine the socio-demography (age, race and gender) of a group of Malaysian patients who were diagnosed as suffering from oral lichen planus (OLP). The occurrence of malignancy was also investigated. A total of 77 clinical and biopsy records of patients with OLP were studied. Females were affected more than males, with the female to male ratio being 2:1. Mid...
