The role of angiogenesis in the development of chronic inflammatory diseases, including oral lichen planus (OLP), is of great concern. The most representative method for the assessment of angiogenesis is the semi-quantification of microvessel density (MVD) using specific markers such as CD105. We aimed to assess the MVD in patients with OLP and find its clinical significance to differentiate the atrophic/erosive forms from reticular ones. This cross-sectional study was conducted on 82 patients with clinically and histopathologically proven cases of OLP, including reticular (n=52) or atrophic/erosive (n=30) lesions. The control group comprised 82 age- and sex-matched subjects without any oral disease. To assess the MVD using CD105, tissue blocks were sliced, and the immunoexpression of CD105 was measured by the standard immunohistochemical staining procedure. The mean value of MVD in OLP patients was significantly higher than that in the controls (14.61±12.48 vs. 8.67±1.76, P<0.0001). Furthermore, there was a significant difference in the mean MVD value between reticular and atrophic/erosive lesions (8.19±7.13 vs. 25.73±12.06, P=0.001). However, no significant difference was observed between the reticular lesions and normal tissues (P=0.58). An increased level of CD105 in OLP patients can improve our knowledge about the causes and mechanisms of the disease. The CD105-MVD assessment might be a useful method for semiquantitative measurement of angiogenesis in OLP patients as well as differentiating its clinical forms; therefore, it can open new vistas for formulating strategies based on antiangiogenic treatments for the management of OLP and other precancerous lesions.

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.

ABSTRACT Introduction Oral squamous cell carcinoma (OSCC) is the most common malignant tumor of the oral cavity. It is preceded by various potentially malignant conditions like oral leukoplakia and oral lichen planus. Survivin is an inhibitor of apoptosis whose levels have been found increased in oral cancer as well as various potentially malignant conditions. Thus survivin can act as a biomarker and help in early detection of potentially malignant conditions which can prevent its transformation into malignancy. Aim To assess and compare the level of total human salivary survivin in oral leukoplakia, oral lichen planus, oral cancer, and control group. Materials and methods A total of 96 subjects were included in the study, which were further grouped into 24 in each group. The saliva was analyzed for survivin level among all the four groups. Survivin concentration (pg/mL) was studied in relation to clinical data. The results were analyzed using Mann—Whitney U test to derive the statistical difference. Results The average of levels of survivin in control group was 0.199 pg/mL, in oral leukoplakia group 0.312 pg/mL, in oral lichen planus group 0.380 pg/mL, and in oral cancer group 0.430 pg/mL. A comparison of all these groups revealed statistically significant difference among the groups. Conclusion Survivin may not be considered as an independent predictor of the malignant transformation for premalignant lesions but it can be an indicator for an increased risk of malignant transformation.

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.

Abstract Background: Oral lichen planus is one of the most prevalent oral diseases. Matrix metalloproteinases have been implicated in its pathogenesis thus this study was executed to evaluate the effectiveness of matrix metalloproteinases neutralizing agents in the treatment of oral lichen planus. Methods: Patients were assigned to either control group who received topical corticosteroids and antifungal treatment, or test group who received matrix metalloproteinases neutralizing spray. All patients were evaluated for disease severity and pain at baseline, 1 week, and 4 weeks after treatment. Results: The mean pain score in test and control groups was 9.00 (0.89), and 9.33 (0.82), respectively, at baseline while it was 2.33 (1.75) and 2.83 (1.72) at 4th week follow up. The mean disease severity score was 4.33 (0.52) for test group and 4.50 (0.55) for control group at baseline and decreased to 1.83 (0.75) and 2.17 (0.98) at 4th week follow up. Despite the better results seen in test group on the expense of control group, no statistically significant differences could be detected between groups at any timepoint. Conclusion: The use of matrix metalloproteinases neutralizing agents might be an equally effective sole treatment for erosive oral lichen planus compared to the conventional treatment, without the risk of secondary candidiasis. Trial registration: The study was registered retrospectively at ClinicalTrials.gov (NCT04336488), date (07/04/2020)

Abstract Objective To compare the clinical effectiveness of various types of high-level laser therapy (HLLT) toward scalpel excision for the surgical treatment of erosive oral lichen planus (OLP). Materials and methods The total number of 128 individuals were enrolled in the study. The 35 did not meet the inclusion criteria due to malignancy signs and presence of diabetes mellitus. In total, 8 were lost to follow-up, and 10 were excluded from the analysis, due to analgesics intake. This way 75 patients with the erosive form of OLP were analyzed in three intervention groups (Er:YAG, n = 19; Nd:YAG, n = 15; Er:YAG + Nd:YAG combination, n = 20) and one control group with scalpel excision (n = 21). The therapy effectiveness has been assessed based on the comparison of salivary interleukin (IL)-1β, IL-6 and interferon (IFN)-γ preoperative levels to 14, 30 days, and 2 years postoperation, as well as pain level and time of epithelization. Results All HLLT groups demonstrated a significantly (p > 0.05) higher IL-1β, IL-6, IFNγ and pain level reduction and quicker epithelization toward the control group on the 30th day, except Nd:YAG in case of IFNγ level. The highest IL-1β, IFNγ and pain level reduction and quicker epithelization on the 30th day was observed in Er:YAG group, followed by Er:YAG + Nd:YAG combination, Nd:YAG respectively. However no significant difference was observed between the HLLT groups with regard to IL-6 level reduction. After a 2-year follow-up, no significant difference was observed between all study groups with regard to all variables. Conclusion HLLT yields a superior clinical outcome compared to the scalpel excision for the surgical treatment of oral lichen planus, whereby the Er:YAG has been proposed as the most effective laser type at the end of the first postoperative month. Clinical relevance For the surgical treatment of erosive OLP the Er:YAG laser may be a preferable treatment option compared to Nd:YAG and scalpel surgery. Trial registration The present trial was registered retrospectively in the German Clinical Trials Register, as a member of WHO international clinical trials registry platform, on the 18.03.2020 with the following number: DRKS00020986

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.
