BACKGROUND AND AIM: Oral lichen planus is a common chronic inammatory disease of the oral mucosa with malignant potential. There are various antioxidant systems in body uid which can neutralize the reactive species. Impaired function of these systems leads to oxidative damage in the tissues and can result in the inappropriate activation of the immune system.Thus reduced antioxidant defense and increased oxidative stress may play an important role in etiology of many chronic immune mediated diseases such as: diabetes, psoriasis, vitiligo. Analyzing the antioxidant capacity in patients with OLP is of signicant value as it can provide essential clues in the etiology of the diseases and help in better management of the disease.This study aimed to assess and compare the antioxidant capacity of oral lichen planus patients and healthy subjects. MATERIALS AND METHODS:This study included 50 oral lichen planus patients and 50 healthy subjects . DPPH Assay is used to assess the antioxidant capacity in OLP patients and healthy subjects. The percentage scavenging of DPPH radical gave the antioxidant activity of the sample. RESULTS:Antioxidant level were reduced in the OLP group while comparing it with the control group. Mean antioxidant level in OLP group was 0.6 and that of the control group was 1.6. Comparison of mean antioxidant levels between the OLP group and control group showed signicant (p<0.0001) difference. The difference between the reticular and erosive OLP group showed signicant difference with p value less than 0.0001. CONCLUSION:Antioxidant level signicantly decreased in OLP group compared to control group.Erosive OLP patients show low antioxidant level compared to reticular OLP patients.The ndings of present study support the hypothesis of the association between antioxidant capacity and OLP.

Introduction. Oral lichen planus (OLP) is a chronic mucocutaneous disease. It is mainly an immune system-related disorder. Vitamins can modulate immune system functions, and thus, vitamin deficiency might have roles in exacerbating OLP. We aim to determine the serum levels of vitamins A, B12, C, D3, and E in OLP patients. Methods and Materials. 34 OLP patients referred to Shiraz Dental School entered the study. Blood samples were collected and levels of A, B12, C, D3, and E vitamins were measured in serum. 43 healthy people were also included as the control group. Serum levels of vitamins were measured by HPLC (A, B12, D3, and E) and Kiazist analyzing kit (vitamin C). Results. Most of the patients were female (62.3%), and the mean age of patients was 48.03 ± 11.57 . Serum levels of vitamins A, C, and E were lower in OLP patients in comparison with the healthy group; however, the difference was not significant. Vitamins B12 and D3 were higher in the OLP group but the difference was not significant. Conclusion. Serum levels of vitamins A, B12, C, D3, and E do not have a significant difference in OLP patients and healthy groups. These vitamins may not have a considerable role in OLP pathogenesis in the southwest of Iran.

Background: microRNAs play a critical role in auto-immunity, cell proliferation, differentiation and cell death. miRNAs are present in all biological fluids, and their expression is essential in maintaining regular immune functions and preventing autoimmunity, whereas miRNA dysregulation may be associated with the pathogenesis of autoimmune and inflammatory diseases. Oral lichen planus (OLP) is an inflammatory disease mediated by cytotoxic T cells attack against epithelial cells. The present study aims to perform a specific microRNA expression profile through the analysis of saliva in this disease. Methods: The study group was formed by five patients (mean age 62.8±1.98 years; 3 females/2 males) affected by oral lichen planus and control group by five healthy subjects (mean age 59.8 years±2.3; 3 females/ 2 males); using a low-density microarray analysis, we recorded a total of 98 differentially expressed miRNAs in the saliva of patients with oral lichen planus compared to the control group. The validation was performed for miR-27b with qRT-PCR in all saliva samples of oral lichen planus group. Results: 89 miRNAs were up-regulated and nine down-regulated. In details, levels of miR-21, miR- 125b, miR-203 and miR15b were increased (p<0.001) in study group while levels of miR-27b were about 3.0-fold decreased compared to controls (p<0.001) of miR-27b expression in OLP saliva. QRTPCR validation confirmed the down regulation of miR-27b in all saliva samples. Conclusions: Collecting saliva samples is a non-invasive procedure and is well accepted by all patients. microRNAs can be readily isolated and identified and can represent useful biomarkers of OLP.

The objective of this study was to evaluate the cellular proliferative potential of oral lichen planus (OLP) lesions from patients without hepatitis C virus (HCV) by means of AgNOR method, as well as the cellular proliferative potential of the normal oral mucosa from patients with HCV, treated or untreated by interferon and ribavirin. A cross-sectional study was developed to investigate four groups: 10 HCV+ patients without clinical signs of OLP who had never been treated for HCV infection - Group 1; 10 HCV+ patients that were under interferon and ribavirin treatment - Group 2; 15 patients with reticular OLP lesions histopathologically confirmed, without HCV - Group 3; and 15 blood donors without HCV infection and no clinical signs of OLP GROUP 4 Control Group. The cytological material of all groups was collected by the liquid-based cytology technique. Then, the sedimented material from each patient was filled with the Nucleolar Organizer Regions impregnation by silver method (AgNOR). The count of NORs was performed on 100 epithelial cell nuclei per patient using the Image Tool(tm) software. The Tukey HSD test was used to compare the median value of NORs among the groups and showed that the oral mucosa of HCV+ patients previously treated with anti-HCV drugs (GROUP 2), presented a higher average number of NORs in relation to others (p<0.05). The anti-HCV treatment may be related to increased cell proliferation of oral mucosa, indicating a possible relationship between OLP and HCV+ patients treated with interferon and ribavirin.

Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous disease, which manifests as a succession of outbreaks. OLP was associated with salivary oxidative stress. Randomized, double blind, parallel-group study was performed. The sample consisted of 55 clinically and histopathologically diagnosed OLP patients. Twenty-six patients were treated with 2%Chamaemelum nobilegel and 29 with a placebo. Nonstimulated (basal) saliva was collected on the first day of the study and 4 weeks later. Salivary total antioxidant status (TAS) was evaluated by four different methods: two TAC (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid) equivalent antioxidant capacity methods (TAC1 and TAC2), cupric reducing antioxidant capacity (CUPRAC), and ferric reducing ability of plasma (FRAP). At baseline (T1), no statistically significant differences were detected in any of the TAS analytes between the two groups of patients. After four weeks of treatment, a statistically significant increase was detected in FRAP in the placebo group (0.323 [0.090–0.467] versus 0.406 [0.197–0.848] mmol/g⁎10-3) (P<0.05). Significant correlations were observed between pain and drainage and TAC1, CUPRAC, and FRAP and between xerostomia and the TAC1, TAC2, CUPRAC, and FRAP. The results of the present study showed that in patients with OLP increases of TAS in saliva are associated with increase in pain and xerostomia and decrease in drainage, suggesting a worsening condition of the patient. The use ofChamaemelum nobilegel would be recommended for disease stabilization.

ABSTRACT Introduction The clinical manifestation of periodontal diseases (such as gingivitis and chronic periodontitis) results from a complex interplay between the etiologic agents such as bacteria that present in the dental plaque, genetic factors, systemic diseases, smoking and exposure of some heavy metals, such as mercury. In this study, we aimed to evaluate hair mercury levels in healthy subjects in comparison with periodontal patients. Materials and methods One hundred twenty subjects were enrolled in this study. The included persons were divided into 3 groups: healthy subjects (n = 40), gingivitis (n = 40) and chronic periodontitis patients (n = 40). Hair samples were collected from occipital area of head. Total mercury levels were determined by atomic absorption spectrophotometry. Results The difference between mercury levels in three groups were statistically significant (p-value < 0.001). Mercury level in periodontitis patients was greater than the gingivitis group (p-value < 0.001). In addition the differences between mercury levels in periodontitis patients vs healthy individuals was significant (p-value = 0.048). The gingivitis patients had lower levels of mercury than the control group, but the difference was not significant (p-value = 0.170). Conclusion The results showed that the levels of mercury are to some extent differed in periodontal diseases in comparison with the healthy individuals. A study with larger sample size is needed for clarification of this issue. How to cite this article Roushan HH, Parsian H, Alijannia R, Mosapour A, Khafri S.

Background: Tumors are distinguished from normal tissues partly by their pronounced variability of cellular and nuclear dimensions. Therefore, such factors may be an indicator to assess whether the cells are malignant or not. Exfoliative cytology is a reliable tool in assessing such changes in the uterine cervix and has been used in the oral cavity also with success. The aims and objectives of the following study were to evaluate the malignant changes by assessing the quantitative parameters such as cytoplasmic diameter, cytoplasmic perimeter and cytoplasmic area (CD, CP, CA) and nuclear diameter, nuclear perimeter and nuclear area (ND, NP, NA) and cytoplasmic to nuclear ratio in the exfoliated cells of various subtypes of oral lichen planus (OLP) using cytomorphometry. Materials and Methods: Oral exfoliated cells from nineteen cases of histologically proven OLP (1 atrophic, 13 reticular, 4 erosive and 1 plaque) and ten controls with healthy mucosa were taken and stained by Feulgen-Rossenback reaction and cytomorphometric analysis was performed using an image analysis software. The parameters taken into account were CD, CP, CA and ND, NP, NA. Furthermore CA/NA was calculated. The parameters were statistically analyzed using the t-test. Results: Cytomorphometric analysis of all the parameters showed no significant difference between the control group and the reticular/plaque subtypes, whereas statistically significant (P < 0.05) differences was obtained between the control group and the atrophic/erosive subtypes group when compared using t-test. Conclusions: The cytomorphometric analysis of OLP shows that erosive/atrophic subtypes of OLP are at more risk and exfoliative cytology and cytomorphometry can be used as a tool to assess the malignant changes.

ABSTRACT Aim Unstimulated whole salivary p53 was assessed in patients suffering from erosive and plaque-like form of oral lichen planus (OLP). Materials and methods Eighteen patients with erosive form, 17 patients suffering from plaque-like form and 38 noninvolvement subjects were enrolled. The unstimulated whole saliva p53 level was assayed by ELISA. Results The mean concentration of salivary p53 was significantly higher in patients with plaque-like form compared to both patients with erosive form and the control group. Conclusion We conclude that plaque like form of OLP is important in view of the potential for malignancy and is not safety form. Clinical significance It seems that all forms of OLP must be considered accurately, should be followed up with biannual examinations, and if possible, assessment of salivary p53 every year.
