Abstract
Oral lichen planus (OLP), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of Hepatitis C virus (HCV) infection, especially in HCV hyperendemic areas such as southern Europe and Japan. The aim of this study was to investigate from an epidemiological standpoint whether HCV infection is an important factor affecting the relative risk of OLP in a Mediterranean population or whether this relates to the degree of HCV endemicity. Two cohorts of OLP patients resident in two different regions of southern Italy (Campania and Sicily; n = 859) were evaluated for HCV infection status and categorized into five age classes to respective region-matched controls. No significant difference was found between OLP patients and the general population in this area, when data were corrected by the age-stratified prevalence of HCV. Therefore, the age-specific prevalence of HCV infection in OLP patients shows a close trend of direct association with increasing age, without significant differences with the general population of each geographical area. An aetiological link between OLP and HCV cannot be inferred solely by epidemiological data.

Abstract
OBJECTIVES We sought to assess the age-specific prevalence of oral lichen planus (OLP) in Mediterranean patients with chronic hepatitis C virus (HCV) and to evaluate the features of OLP in relation to sex, smoking, HCV genotype, HIV-1 coinfection, and antiviral treatments. METHODS In all, 178 anti-HCV-positive adults (60 women and 118 men; age range 20-66 years) recruited from two cohorts (104 HIV-negative patients and 74 patients with HIV coinfection) underwent oral examination. RESULTS Overall prevalence of OLP was 2.8% (5 of 178) (male/female ratio 0.2; odds ratio=0.119; 95% confidence interval=0.013-1.106), only among HIV-negative participants, always in the reticular pattern, and in the adult age. HCV genotype, tobacco smoking, and treatment (interferon alfa/ribavirin) were not significantly associated to OLP. CONCLUSIONS Among HCV-infected patients, we found a low prevalence of OLP. The absence of OLP in HIV-coinfected patients suggests immunosuppression secondary to defective CD4 functions.

Abstract
INTRODUCTION The chronic liver disease is a pathology produced, mainly, by the alcohol chronic abuse and by the hepatitis B and/or C virus infection. In the last years, it has been widely discussed the possible association between chronic liver disease and oral lichen planus. Recently, it has been suggested that the association between oral lichen planus and liver disease has a viral origin. MATERIAL AND METHOD The objective of this transversal matched study is to know if there is a relationship between B and/or C viral chronic hepatitis and oral lichen planus. Two groups of 100 patients were selected: a case group with patients. Infected with hepatitis B and/or C virus, and a control group without liver disease matched in age and gender. Oral cavity was explored to detect lichen planus in both groups, but we registered other mucosal alterations. RESULTS We did not found any patient of the case group with oral lichen planus, but four patients with this disease in the control group. CONCLUSIONS In our study we did not found any association between the infection with the hepatitis B and/or C virus and oral lichen planus.

Abstract
OBJECTIVE Dental treatment involves the use of a wide range of materials. Many of the dental materials or their components pose a potential risk to the patient and member of the dental team. Pre-market biocompatibility testing cannot guarantee absolute safety, making monitoring of materials likely to cause an adverse reaction essential. The prevalence of adverse reactions to dental materials amongst dental patients and staff has not been systematically monitored in the UK. This project aims to develop a systematic approach to the evaluation and monitoring of the extent and severity of adverse reactions to dental materials in the UK. METHOD Through the distribution of reporting forms to dental surgeries and laboratories in the UK, the ARRP has received 1,075 complete reports relating to adverse reactions seen or experienced by dental staff and patients. RESULTS The main findings were that different materials cause adverse reactions to different groups of people. The largest proportion of patient related adverse reactions were reported to be due to metals (n = 175). These were mainly amalgam associated oral lichenoid reactions (n = 124). Dental technicians reported acrylic resin as the causal factor of hand dermatitis in 61% (44 out of a total 72) of cases reported. Finally, dental surgery staff reported gloves as causing hand dermatitis in 75% of cases (398 out of a total 531). CONCLUSIONS Different dental materials affect different person groups depending on their exposure to the material. Dental staff are most at risk from an adverse reaction to latex gloves, whereas most reported reactions for patients were due to metals. For dental technicians the biggest danger of an adverse reaction was from acrylic resins. There is a need to continue to raise the awareness among dental professionals of the existence of the Adverse Reactions Reporting Project so as to overcome problems of under-reporting.

Abstract
The most important complication of oral lichen planus (OLP) is the development of oral squamous cell carcinoma (OSCC) but this is a very controversial matter. The aim of the study was to estimate in a Northern Italian cohort of OLP patients the risk for OSCC. Four hundred and two patients with histologically confirmed OLP diagnosed from January 1988 to July 1999, were followed-up to the end of February 2001. The standardized incidence ratio (SIR) of OSCC was calculated for the entire cohort and specific for gender, type of OLP, therapy for OLP and hepatitis C virus (HCV) infection. The relative risk (RR) of OSCC according to HCV infection was also estimated in the cohort. During the follow-up period, two men (1.3%) and seven women (2.9%) developed an OSCC. The SIR was 44.9 (95% CI: 20.5-85.2), being higher among women, but statistically significant in both genders. The RR of OSCC for patients with HCV as compared with those without HCV infection was 3.16 (0.8-12.5). Patients with OLP had a significantly increased risk of OSCC, irrespective of the clinical type of OLP and therapy. HCV infection apparently increased the risk for OSCC although this result could reflect the role of confounders, such as liver cirrhosis.

Abstract
Most lymphocytes in the lamina propria of oral lichen planus (OLP) lesions express and secrete interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha), whereas they do not secret interleukin-4 and -10 or transforming growth factor-beta. We analyzed whether the polymorphisms of several cytokines may influence the susceptibility to OLP. Cytokine typing was performed by a sequence-specific PCR assay. Thirteen cytokine genes with 22 single-nucleotide polymorphisms were studied. IFN-gamma UTR 5644 genotype frequencies showed a significant increase in number of T/T homozygotes in OLP patients compared with controls (40.9 vs. 22.9%; p=0.0022). Moreover, in OLP patients, the frequency of the -308A TNF-alpha allele was higher than in the controls (21.6 vs. 9.3%; p < 0.05) causing a significantly increased frequency of the genotype G/A in OLP (43.2 vs. 14.3%; p=0.0002). Because in patients with mucocutaneous lichen planus (LP), the frequency of the -308A TNF-alpha allele was more than double the values in the pure OLP patients (40.9 vs. 15.1%; p=0.003), the -308G/A TNF-alpha genotype showed a significantly higher frequency in patients with mucocutaneous LP than in patients with pure OLP (81.8 vs. 30.3%, p=0.003). In conclusion, we suggest that genetic polymorphism of the first intron of the promoter gene of IFN-gamma may be an important risk factor to develop oral lesions of LP, whereas an increase in the frequency of -308A TNF-alpha allele may best contribute to the development of additional skin involvement.

Abstract
This study aimed to characterize the clinical profile of patients with oral lichen planus (OLP) and to evaluate the efficacy of topical, systemic and/or intralesional corticosteroids in the management of symptomatic cases. Fifty-two patients with OLP, 33 females and 19 males, aged from 17 to 75 years (mean 49.7 years) were studied. Information regarding the clinical forms, sites of involvement, patients' medical history and habits were recorded. Diagnosis of OLP was made using clinical criteria alone in 32 cases, while biopsy examination was required in the remaining 20. Symptomatic lesions were seen in 29 patients, who were treated with corticosteroid. Asymptomatic cases (23) were only clinically monitored. The forms of OLP found in this study were reticular (47%), atrophic (24%), erosive (21%) and plaque-like (8%). The buccal mucosa was the site predominantly affected. Systemic diseases were found in 17 patients (seven diabetic and ten with hypertension) but these data lacked statistical significance (p > 0.05) when compared with a control group of age and gender matched patients without any type of mucocutaneous disease. A habit of tobacco and/or alcohol use was reported by 11.5% of the patients, most of them with the reticular form of the disease. Topical corticosteroid therapy alone was effective in producing relief of symptoms in 18 of the 29 patients, although some relapses occurred after discontinuation. For lesions non-responsive to topical treatment, intralesional injection and/or short-term use of systemic corticosteroids were used.

Abstract
BACKGROUND The possible increased risk of oral lichen planus (OLP) in patients with chronic liver diseases is a controversial issue. PATIENTS AND METHODS We investigated a total of 156 outpatients with known liver diseases for occurrence of OLP. Hepatitis C virus (HCV) infection was proven for 117 patients (75%) and hepatitis B virus (HBV) infection for 16 patients (10.3%). Four patients were coinfected with HCV and HBV. An alcohol-derived hepatic cirrhosis was found in 23 patients (14.7%). Three patients had a biliary cirrhosis and one had a primary sclerosing cholangitis. Patients suspected of having OLP were transferred to the Department of Oral and Maxillofacial Surgery where excisional biopsies were taken. RESULTS Eight patients had a white alteration of the oral mucosa. OLP was suspected in five of them and was confirmed histologically in four. The alteration of the fifth patient disappeared during continued interferon therapy. CONCLUSION Our results show that there is no increased prevalence of OLP manifestation in patients suffering from HCV infection.

Abstract
Oral lichen planus (OLP) is generally regarded as a premalignant condition. The objective of the present study was to assess the number of oral malignant tumours in a retrospective analysis of 1028 patients (mean age=55 years; range=18-86; female, n=667; men, n=351) who between 1978 to end of 1993 were diagnosed with OLP at the Faculty of Odontology, Göteborg University, Sweden. Patients with malignant tumours were identified through the Swedish Cancer Registry at the National Board of Health and Welfare, which annually reports the incidence of malignant neoplasms in the Swedish population. The incidence of oral squamous cancer (OSCC), other malignant tumours and survival in the study group was compared to the Swedish population. The total time with OLP in the study group amounted to 7009 person years, with a mean follow up of 6.8 years (SD=4.9). The observed incidence of OSCC was higher than the expected incidence in the study group. The difference was statistically significant (P<0.001). No statistically significant difference was found for any other malignant tumours than OSCC. Also, no statistically significant difference could be identified in survival between study group and the population. The results from the present study gives further support to the concept of a small but increased risk for development of squamous cell carcinoma in patients with OLP.

Abstract
BACKGROUND The presentation of oral lichen planus in anti-hepatitis C virus (HCV) seropositive and seronegative patients was previously evaluated, and the keratotic form of oral lichen planus was found to be more prevalent in anti-HCV seropositive patients. This study evaluated the presentation of cutaneous lichen planus in anti-HCV seropositive and seronegative Nigerians. METHODS Fifty-seven Nigerians with cutaneous lichen planus were carefully examined to determine the form of lichen planus present. All were screened for the presence of anti-HCV by second-generation enzyme-linked immunosorbent assay (ELISA) and grouped as anti-HCV seropositive or anti-HCV seronegative patients. RESULTS Nine patients were anti-HCV positive. Seven of these seropositive patients had hypertrophic lichen planus. CONCLUSION Hypertrophic lichen planus in Nigerians is more prevalent with HCV infection.

Abstract
This article presents a review of the literature on oral lichen planus, focusing on important aspects of its epidemiology, etiopathogeny, and clinical manifestations. The oral form is an important clinical presentation of lichen planus. It may precede or accompany the skin lesions, or it may be the only manifestation of the disease. Dermatologists, dentists, otorhinolaryngologists, and other specialists who deal with the oral cavity must be aware of this disease so they can diagnose, treat, and keep these patients under observation.

Abstract
OBJECTIVE To evaluate the prevalence of oral precancerous lesions in textile workers. MATERIALS AND METHODS A cross-sectional study was undertaken to assess a total of 1167 textile factory workers randomly selected from a total of 6947. An overall 97 women and 1070 men aged 18-69 years (mean=31.8 years) were studied. Regular smoking during the past 6 months was considered as the smoker group. Leukoplakia lesions were classified in accordance to Axell criteria [Axell T, Pindborg JJ, Smith CJ and Van-der-waal I (1996). J Oral Pathol Med 25: 49]. RESULTS The results showed that 115 workers (9.9%) had red and white lesions. Among these 43 positive detections (3.7%) had leukoplakia and six cases (0.5%) had lichen planus. The smoking habits of the workers were limited to cigarette smoking. There was a statistically significant positive correlation between tobacco smoking and oral leukoplakia (P<0.001). CONCLUSION There was a statistically significant positive correlation between tobacco smoking and leukoplakia in this relatively young cohort with generally mild tobacco use. The prevalence of leukoplakia had an inverse relationship with the level of education.

Abstract
The epidemiologic data on oral lesions in native Indians remain unknown in many countries around the world. This paper reports the prevalence and distribution of oral congenital anomalies and pathologic lesions found in a survey of 107 schoolchildren (ages 12 to 17), from two isolated communities in the ethnographic Mazahua area in the State of Mexico. The main entities identified were: pigmented lesions (47.6%), lingual anomalies (17.4%) and developmental tooth alterations (6.9%). The remaining 24.4% of the lesions were gingival inflammatory hyperplasia, partial ankilosis of the tongue, lichen planus, focal epithelial hyperplasia and the double lip. The most frequent localization was lips and tongue. These findings suggest the high prevalence of oral anomalies in this Indian population. Therefore, we suggest that health programs should emphasize the prevention, diagnosis and treatment of these pathologies in Indians groups.

Abstract
AIMS To assess the prevalence of malignant transformation of atypical lichen planus in our medium and describe the clinico-pathological features of the cases that had a premalignant potential. MATERIALS AND METHODS we performed a retrospective analysis of the records of patients seen at the Stomatology Department of the School of Dentistry, University of Buenos Aires, during the period 1991-1997. A total of 719 patients (7.02%) had oral lichen planus (481 women and 238 men). From a clinico-pathological point of view, 228 (31.7%) were typical forms and 491 (68.3%) were atypical forms. In all of the cases, lichen planus was confirmed histologically and a clinical protocol was followed. RESULTS Thirty-two (6.51%) patients were known to have developed malignant changes. In these cases the lesions had been diagnosed as atypical lichen planus at the outset. The most frequent clinical presentations were the keratotic (plaque-like) and erosive forms. Most of the lesions were on the tongue. The results support a premalignant potential for atypical lichen planus. CONCLUSION Oral lichen planus is a precancerous condition. The atypical form, particularly in its keratotic and erosive presentations, has a premalignant potential in our medium. The most frequent localization is the tongue.

Abstract
BACKGROUND Lichen planus is a common mucocutaneous disease of unknown aetiology. Oral disease affecting the mouth and the pharynx occurs in 30-70% of the cases. Oesophageal disease is considered to be extremely rare. The diagnosis of oesophageal involvement is often not made until complications occur. CASE REPORT A 56-year-old woman with oral and genital erosive lichen planus for more than 4 years complained of odynophagia and dysphagia. Episodes of oesophageal bolus obstruction started 2 months earlier. Upper endoscopy revealed a high-grade concentric stenosis at 21-24 cm from the incisors. Biopsy specimens taken after bougienage showed a squamous epithelium with dense leukocyte infiltration and Civatte bodies. The bougienage led to complete relief, but due to recurrent symptomatic stenosis, endoscopic dilatation had to be performed another four times within 5 years of follow-up. Immunosuppressive therapy with systemic and local steroid application did not prevent recurrent stenosis. CONCLUSIONS Patients with lichen planus should be evaluated for gastrointestinal symptoms because oesophageal involvement is a rare but severe complication leading to inflammatory stenosis. The benefit of immunosuppressive therapy in the prevention of recurrent stenosis is not established. A review of all reported cases is done with particular regard to therapy.

Abstract
OBJECTIVES The goals of this study were as follows: to obtain baseline information on the incidence of oral mucosal conditions in a population of elderly Thai patients and to investigate differences in the presentation of these findings in relation to age, sex and the wearing of dentures. SUBJECTS AND METHODS The incidence of oral mucosal conditions was determined by the clinical examination of a sample of 500 Thai patients aged 60 years and older. RESULTS The overall incidence of oral mucosal conditions was 83.6% with no significant difference between men (81.4%) and women (85%). The incidence of oral mucosal conditions indicated a significant increase with advancing age. Varices (59.6%), fissured tongue (28%) and traumatic ulcer (15.6%) were the three most common conditions; and the incidence increased with age. Leukoplakia and smoker's melanosis were more common in men whereas lichen planus was seen more frequently in women. Three cases of oral cancer were detected, representing an incidence of 0.6%. Denture wearers (62.7%) exhibited a significantly higher prevalence of oral mucosal conditions than subjects who had no dentures (28.5%) and subjects with crowns and/or bridges (8.8%). The three most common denture-related problems were traumatic ulcer (22.6%), denture stomatitis (14.3%) and angular cheilitis (4.8%). In addition, the incidence of denture-related conditions among complete denture wearers (46.3%) was higher than in those wearing partial dentures (40.8%). CONCLUSION The current results regarding an elderly Thai population support the studies of other populations whereby the incidence of oral mucosal conditions in the elderly is related to age, sex and the wearing of dentures.

Abstract
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. Middle-aged Indian and Chinese females tend to be affected by OLP when compared with the rest of the population. Only 19 patients returned for further follow-up. One adult Indian female with a six-year history of lichenoid reaction showed the presence of malignancy.

Abstract
The premalignant potential of leukoplakia is controversial. This study is intended to determine whether chronic oral "white lesions" demonstrated premalignant potential by investigating the population presented to the University Hospital of Wales in Cardiff between January 1996 and June 2000. Patient demographics are presented. During this period, 510 biopsies were performed on suspicious white lesions and 311 cases of oral cancer were diagnosed. During the same period, 11 of the 311 patients developed malignancy despite initial benign diagnosis. Thirty-four of the 510 biopsies were initially diagnosed as oral lichen planus (OLP), whereas 3 of the previously mentioned 11 were diagnosed as OLP and later developed squamous cell carcinoma. This represents an incidence of detected premalignancy in 3.5% of oral cancer cases. On re-examination of the initial biopsy specimens, these 3 cases met criteria for OLP in some areas, whereas the others appeared hyperkeratotic. These specimens may represent a subtype of premalignant chronic white lesions rather than exemplify the premalignant potential of OLP. Further direction of research will be discussed.

Abstract
Oral Lichen Planus and Leukoplakia are two precancerous lesions of great relevance in oral pathology. A total of 4183 patients from the National University of Córdoba (UNC) and 4838 patients from the University of Buenos Aires (UBA) who had been admitted to the corresponding Oral Pathology Departments were analyzed. Of the total number of patients, 476 corresponded to Lichen Planus cases and 418 to Leukoplakia cases. Of the 476 Lichen Planus cases, 330 came from UBA and 146 from UNC, whereas of the 418 cases of Leukoplakia, 284 came from UNC and 134 from UBA. These differences were statistically significant (p < 0.02). Distribution according to sex and age was similar for Lichen Planus and Leukoplakia patients from both Oral Pathology Departments. The association between diabetes and Lichen Planus was similar for both centers, 11.5% for UNC and 14% for UBA. Similarly, no differences were found in terms of the association with tobacco consumption and dental microtrauma. Twenty-two percent of UNC patients were smokers whereas only 11% of UBA patients were smokers. This finding could explain the larger amount of Leukoplakia in UNC. The differences in the incidence of Lichen Planus could be attributed to the fact that the Buenos Aires population is under greater stress and the higher incidence of Leukoplakia in UNC could be related to the smoking habits of this population.

Abstract
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 individuals seeking dental treatment at our school, used to determine the prevalence of lichen planus in the general population. The prevalence of HCV in group 1 was determined and compared with that of the population of São Paulo (Focaccia et al (1998) Brazilian J Infect Dis 2: 269), while the prevalence of OLP in group 2 was determined and compared with that of the control group. RESULTS The results showed that the frequency of HCV in OLP patients was 8.8%, significantly higher than in the general population of São Paulo, which is 1.4% (P = 0.002), and the frequency of OLP in HCV patients (4.7%) was also significantly higher (P = 0.0003) than that of the control group (0.6%). CONCLUSION These data suggest that, at least in São Paulo, there is an association between OLP and HCV infection.
