Abstract
BACKGROUND For symptomatic oral lichen planus (OLP), a wide range of therapeutic approaches have been suggested. To minimize discomfort and symptoms among individuals with symptomatic OLP, extensive therapy is frequently needed. Therefore, finding a new therapeutic approach that may effectively manage OLP's symptoms and signs while having few adverse effects continues to be a difficult task. Recently, low-level laser therapy (LLLT) has become a popular alternative therapy option for OLP with no serious side effects. AIM The present research was designed to compare the effectiveness of a combination regimen of LLLT in addition to topical steroids with routine topical steroid therapy separately in order to manage patients with bothersome OLP with an extended period of follow-up. MATERIALS AND METHODS In our trial, 60 patients were chosen and given sequential numbers as they signed up to take part. The participants were divided randomly into two categories: category A (LLLT plus topical steroids) and category B (only topical steroids). The data were entered into the aforementioned prepared case template after receiving informed consent. The aforementioned prepared case template included the following criteria for evaluating the result of the treatment: pain, recurrence, burning sensation, clinical remission, and size of the lesion. Applying the visual analog scale (VAS), pain, as well as burning sensations, were assessed in both categories. With the aid of the Electronic Digital Vernier Caliper (Mitutoyo, China), these individuals were assessed for the dimension of the lesion. RESULTS The pain score on day 21 of intervention in category A was 2.5, while it was 4.63 in category B. The difference in findings was significant statistically at day 21 (p = 0.0032). The pain score on day 28 of intervention in category A was 1.3, while it was 3.0 in category B. The difference in findings was significant statistically at day 28 (p = 0.003). The pain score was greater in the control category as compared to the intervention category. The burning sensation score on day 21 of intervention in category A was 2.5, while it was 4.5 in category B. The difference in findings was significant statistically (p = 0.0024). The burning sensation score at the follow-up phase on day 45 of intervention in category A was 1.1, while it was 3.4 in category B. The difference in findings was significant statistically (p = 0.002). CONCLUSION Newer therapeutic techniques are becoming accessible to oral specialists for controlling oral mucosal disorders as a result of evolving dental trends. The gold standard for treating people with symptomatic OLP continues to be topical corticosteroids. The therapeutic advantages of topical corticosteroids, however, are considerably outweighed by their complementary effect when paired with newer treatment methods like LLLT.

Abstract
BACKGROUND The treatment options for oral lichen planus (OLP) are numerous and include topical and systemic agents. Intralesional and systemic corticosteroids are used; however, the therapeutic results are often disappointing. OBJECTIVE To compare the influence of ozone, laser, and topical corticosteroid therapies in the treatment of OLP. METHODS One hundred twenty adult patients with ≤3 cm atrophic-erosive biopsy-proven OLPs in the tongue or buccal mucosa were recruited into the study. They were randomly assigned, by preoperative envelope drawing, to be treated with low-level laser therapy (LLLT group), ozone therapy (ozonated group), and topical corticosteroid therapy (positive control group). A placebo treatment containing base ointment without the active corticosteroid component was administered to patients in the negative control group. Response rate scores were determined on the basis of changes in the appearance score and pain score of the lesions between baseline and after each treatment. RESULTS The study subjects consisted of 56 male and 64 female OLP patients with a combined mean age of 42.6±8.3 years (range, 28~55 years). No statistically significant difference was detected in clinical severity among the groups. The sign scores decreased in almost all scoring groups; however, statistically significant improvement was found in the ozonated and corticosteroid-treated groups. Symptom improvement was achieved after treatment with LLLT, ozone, and corticosteroid (p<0.05). The efficacy indices were significantly higher in the ozonated and corticosteroid-treated groups. CONCLUSION Ozone and corticosteroid therapies were more effective than 808-nm LLLT in the treatment of OLP.

Abstract
Lichen planus (LP) is a mucocutaneous disease of chronic inflammatory nature, commonly seen in dermatological and dental clinics; it is a relatively common disorder of stratified squamous epithelia, frequently exclusively involving the oral cavity. Oral Lichen Planus (OLP) is often asymptomatic, the atrophic-erosive form can cause symptoms ranging from burning sensation to severe pain, interfering with speaking, eating, and swallowing. Lichen planus is regarded as a premalignant lesion. This review discusses the role of hepatitis C virus (HCV), bacterial and fungal infection in LP. Analysing the seroprevalence of HCV infection in LP patients and patients with oral OLP in particular, which was the case in the vast majority of studies, the association varied from 0% to 62% and seemed to be connected to the high HCV seroprevalence in the general population. Candida albicans is present in about 37% of oral LP lesions. The aim of this review is to summarize what is new in the pathogenesis and treatment of OLP.

Abstract
Hepatitis C virus (HCV) is a significant health problem facing the world. This virus infects more than 170 million people worldwide and is considered the major cause of both acute and chronic hepatitis. Persons become infected mainly through parenteral exposure to infected material by blood transfusions or injections with nonsterile needles. Although the sexual behavior is considered as a high risk factor for HCV infection, the transmission of HCV infection through sexual means, is less frequently. Currently, the available treatment for patients with chronic HCV infection is interferon based therapies alone or in combination with ribavirin and protease inhibitors. Although a sustained virological response of patients to the applied therapy, a great portion of patients did not show any response. HCV infection is mostly associated with progressive liver diseases including fibrosis, cirrhosis and hepatocellular carcinoma. Although the focus of many patients and clinicians is sometimes limited to that problem, the natural history of HCV infection (HCV) is also associated with the development of several extrahepatic manifestations including dermatologic, rheumatologic, neurologic, and nephrologic complications, diabetes, arterial hypertension, autoantibodies and cryglobulins. Despite the notion that HCV-mediated extrahepatic manifestations are credible, the mechanism of their modulation is not fully described in detail. Therefore, the understanding of the molecular mechanisms of HCV-induced alteration of intracellular signal transduction pathways, during the course of HCV infection, may offer novel therapeutic targets for HCV-associated both hepatic and extrahepatic manifestations. This review will elaborate the etiopathogenesis of HCV-host interactions and summarize the current knowledge of HCV-associated diseases and their possible therapeutic strategies.

Abstract
Although hepatitis C virus (HCV) infection is associated with oral lichen planus (OLP), a case-control study and a meta-analysis were designed to investigate the magnitude of such an association. A total of 413 presumptive OLP patients (18-75 years) who referred to a dental clinic in Rasht (Iran) were consecutively selected. OLP was diagnosed clinically (typical forms) and histologically (atypical forms) by a calibrated examiner. A total of 487 adults (20-77 years) attending the same dental clinic were the controls. The two groups were homogeneous in terms of age, gender and occupation. Subjects were tested for anti-HCV antibodies. The odds ratio (OR) for OLP attributable to HCV infection was non-significant [OR 1.2, 95% confidence interval (95CI) 0.3-4.8], suggesting that the association between HCV and OLP was weak in the Iranian context. Meta-analysis of observational studies characteristics of primary studies were that cases were diagnosed clinically (only typical forms) and histologically and exposure was assessed through anti-HCV antibodies. Exposed/unexposed cases/controls were extracted and zero values were appropriately transformed. As much as 44 studies, including the present, were located. Publication bias could not be totally excluded. The pooled OR, estimated using the random-effect model, was 2.8 (95CI 2.4-3.2). Sensitivity analysis confirmed the robustness of results. Subgroup analysis showed non-significant differences between American/European and Asian/African studies. The fraction of global OLP cases associated with HCV (population attributable fraction) was 2.1% (95CI 1.9-2.2%). Although HCV and OLP were significantly associated, the majority of OLP patients were not affected by HCV.

Abstract
Some of the most frequent extrahepatic manifestations of hepatitis C virus (HCV) infection involve the oral region predominantly or exclusively. Part 2 of this review discusses the current evidences regarding the association of lichen planus (LP) and other diseases frequently involving the oral cavity with HCV. Epidemiological data suggest that LP may be significantly associated with HCV infections especially in southern Europe and Japan but not in northern Europe. These geographical differences are possibly influenced by immunogenetic factors, the duration of the HCV infection and the design of the published studies. Because of the fact that most of the studies published are retrospective, it is impossible to establish whether the HCV exposure occurred earlier to or after the onset of disease and more prospective studies are clearly warranted. As the virus may replicate in the skin and oral mucosa and HCV-specific T lymphocytes can be found in the oral mucosa of patients with chronic hepatitis C and LP, HCV may be implicated in the pathogenesis of LP. However, little attention has been paid to the variable effect of therapy with interferon-alpha (IFN-alpha), with or without ribavirin for LP. Conversely, it is unlikely that other oral diseases such as oral carcinoma, pemphigus and Behcet disease are triggered by HCV.

Abstract
OBJECTIVE The aim of the study was to investigate the possible epidemiological relationship between hepatitis C virus (HCV) chronic infection and oral lichen planus (OLP) in centre-south Italy. METHODS In a case-control study three groups of patients were investigated: group 1 (82 patients): patients with histologically confirmed OLP were tested for HCV infection; group 2 (165 patients): patients with chronic HCV infection were examined for OLP; group 3 (466 participants): control group: healthy individuals who had been hospitalized in the Trauma-Orthopaedic Ward and had been tested for HCV. RESULTS In group 1, 11.4% of the participants were HCV-positive and HCV was found in 10.8% of the patients above 50 years of age. Eight participants (5.5%) of group 2 showed lesions possibly related to OLP: only two had a histology consistent with OLP. In group 3, 5.4% participants had chronic HCV infection, but HCV was found in 10% of the participants of 50 years and above. A weak overall association between HCV and OLP (odds ratio 2.27; 95% confidence interval 0.94, 5.35; P<0.05) was seen and the result was not statistically significant in participants aged 50 years and above (odds ratio 1.08; 95% confidence interval 0.39, 2.88; P=0.86). CONCLUSION Our data suggest that no clear association exists between OLP and chronic HCV disease. It is possible that the association is mainly due to the frequency of each disease in the population.

Abstract
Despite recent advances in understanding the immunopathogenesis of oral lichen planus (LP), the initial triggers of lesion formation and the essential pathogenic pathways are unknown. It is therefore not surprising that the clinical management of oral LP poses considerable difficulties to the dermatologist and the oral physician. A consensus meeting was held in France in March 2003 to discuss the most controversial aspects of oral LP. Part 1 of the meeting report focuses on (1) the relationship between oral LP and viral infection with special emphasis on hepatitis C virus (HCV), and (2) oral LP pathogenesis, in particular the immune mechanisms resulting in lymphocyte infiltration and keratinocyte apoptosis. Part 2 focuses on patient management and therapeutic approaches and includes discussion on malignant transformation of oral LP.

Abstract
BACKGROUND The association between hepatitis C virus (HCV) and oral lichen planus (OLP) is more common in the Mediterranean area and Japan, possibly because of immunogenetic factors. METHODS Intermediate-resolution HLA-DRB typing by hybridization with oligonucleotide probes was performed in 31 Italian OLP patients with HCV infection, in 45 Italian OLP and in 48 British OLP patients without HCV infection. As healthy controls we included data from 145 unrelated Italian and 101 unrelated British bone marrow donors. RESULTS Italian HCV+ve OLP patients possessed the HLA-DR6 allele more frequently than Italian and British OLP patients without HCV infection (51.6% vs. 17.7% vs. 16.7%; P corrected = 0.028 and 0.017, respectively). There was no difference in the frequency of the HLA-DR6 allele between Italian and British control subjects. CONCLUSIONS The present data suggest that HLA-DR6 may be responsible for the peculiar geographic heterogeneity of the association between HCV and OLP.

Abstract
Morbidity associated with hepatitis C virus (HCV) infection can involve a variety of extrahepatic conditions, including lichen planus (LP) and sialadenitis, predominantly or exclusively involving the oral region, conditions which have been largely neglected in reviews. The literature suggests that HCV-infected patients may frequently have Sjögren-like sialadenitis with mild clinical symptoms, whereas oral LP may be significantly associated with HCV infections in Southern Europe and Japan but not in Northern Europe. These geographical differences could be related to immunogenetic factors such as the HLA-DR6 allele, significantly expressed in Italian patients with OLP and HCV. Analysis of experimental data suggests that HCV could be involved in the pathogenesis of both these diseases. Moreover, parotid lymphoma may arise in patients with sialadenitis, mainly with type II cryoglobulinemia. Little attention has been paid to oral health needs in HCV-infected patients and the variable effect of interferon-alpha therapy on oral tissues. Further research is needed, because of the potentially great influence of oral diseases possibly linked to HCV on the quality of life of millions of patients.

Abstract
Lichen planus (LP) is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as esophageal or ophthalmological involvement are underdiagnosed. The burden of the disease is higher in some variants including hypertrophic LP and erosive oral LP, which may have a more chronic pattern. LP can significantly affect the quality of life of patients as well. Drugs or contact allergens can cause lichenoid reactions as the main differential diagnosis of LP. LP is a T-cell mediated immunologic disease but the responsible antigen remains unidentified. In this paper, we review the history, epidemiology, and clinical subtypes of LP. We also review the histopathologic aspects of the disease, differential diagnoses, immunopathogenesis, and the clinical and genetic correlations.
