Participants with symptomatic Oral Lichen Planus lesions will be treated with Rivelin® patches containing either 0, 1, 5, or 20 μg clobetasol per patch. Each participant will apply up to 6 patches twice daily for 4 weeks.
Treating Oral Lichen Planus (OLP) is a big challenge for clinicians. Despite numerous existing remedies, to date no effective cure has been found, which is mainly attributed to the lack of understanding of the pathogenesis of the disease. The investigator's aim was comparing the effectiveness of topical steroids and diode laser in treating OLP patients. Twenty-four patients with OLP were allocated into two groups of twelve patients each. One group was treated with 970 nm diode laser applied twice weekly and the other group was treated with topical steroids applied four times per day. Patients were followed up for two months. Pain was recorded using the visual analog score (VAS) and the clinical signs and symptoms were recorded using the reticular, atrophic, erosive (RAE) sores. Pain and RAE records were taken before treatment, after treatment and after 2 months.
Oral lichen planus (OLP) is a common chronic autoimmune disease associated with cell-mediated immunological dysfunction. Symptomatic OLP is painful and complete healing is rare. Current treatments for lichen planus and lichenoid mucositis are usually directed towards reducing the symptoms. This double-blinded cross-over placebo-controlled clinical trial is designed to measure the effectiveness of a topical NSAID (Ibuprofen suspension - 100mg/5ml) compared with a placebo in reducing pain associated with Oral Lichen Planus and Oral Lichenoid Lesions. Exclusion criteria include: - The occurrence of dysplasia in the histopathological specimen - Known or suspected sensitivity to NSAID medication - History of asthma - History of gastrointestinal ulceration - History of bleeding disorders - Pregnancy Outcome measures are self-reported pain scores at day 0, day 4 and day 7 of use of the placebo or active suspension, using a horizontal 100 mm, visual analog scale (VAS). If subjects were already on active treatment at the time of enrollment, they will be asked to discontinue for 7 days for a washout period before starting the research study. cord their spontaneous pain level on a 0-10 VAS. Participants will be contacted initially after the first day of the intervention to discuss any concerns or questions. Every week, reminder phone calls will be made to the subjects to fill out the forms from the investigator and to check for any side effects from the intervention. Both the patient and the investigator will be blinded for the content of each bottle.
Is topical application of green tea polyphenols buccal tablet more effective in treatment of patients with symptomatic oral lichen planus in comparison with topical application of corticosteroids and what is the most effective concentration of polyphenols
Lichen planus is a chronic inflammatory mucocutaneous disease, which often results in oral manifestations, receiving the name of oral lichen planus (OLP). Its frequency varies from 0,1 to 4% of the general population, with a higher incidence in women, around the 4th and 5th decades of life. Although the pathogenesis of OLP is related to a immune-cellular response, mainly mediated by T lymphocytes, its cause remains unknown. Considering its chronic nature, control of OLP aims to reduce symptoms and improve function, and agents with anti-inflammatory action, especially topical corticosteroids result in some degree of success in most patients, depending on the clinical presentation. However, some cases are resistant to the use of corticosteroids, thus justifying the search for new therapeutic options. The immunomodulation proved to be one of the main functions of probiotic bacteria, and recent studies have shown effect of probiotics on decreasing the expression of inflammatory markers, which enables the study of this therapy as an alternative to the control of OLP. Thus, this project aims to evaluate the effects of therapy with Bifidobacterium animalis subsp. lactis HN019 comparing with clobetasol propionate 0.05% in symptomatic patients with OLP referred for diagnosis and treatment of School of Dentistry of Ribeirão Preto - University of São Paulo (USP). The impact of the topical therapy (probiotic or corticosteroid) on the clinical, histopathological and immunopathological features will be evaluated. This project was previously submitted and approved by the Institutional Review Board of the School of Dentistry of Ribeirão Preto/USP, and all patients must give informed consent to participate in this study.
Diabetes mellitus is among the most common chronic diseases, with significant and well documented impact on oral cavity health. Among the most common diseases of the oral cavity mucosa and complications in patients with impaired glucose metabolism and diabetes mellitus is oral lichen ruber (OLR), which according to World Health Organisation (WHO) is considered potentially malignant disorder. It was found that lichen ruber in diabetes mellitus has a much more aggressive clinical course in the form of atrophic-erosive and ulcerative lesions showing an increased tendency to malignant transformation. Although OLR etiology is unknown, evidence suggests cell-mediated autoimmune pathogenesis. OLR epithelial cells show anomalies in both enzymatic activity and carbohydrate metabolism, which may be related to hormones regulating carbohydrate, insulin and insulin-like growth factors 1 and 2 (IGF-1 and IGF-2) metabolism. The hypothesis of our research is that patients with diabetes mellitus and oral lichen ruber lesions will have a disturbance of insulin-like growth factors 1 and 2 and hence a greater risk of malignant transformation, compared to patients with oral lichen ruber without diabetes and healthy patients without alterations in the oral mucosa.
Background: Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous autoimmune disease mainly affecting stratum basal of the epithelium. It is very painful and hamper the daily routine of patients e.g. (talking, drinking, eating, maintaining normal relationships). Different topical treatments have been tried for the symptomatic relief of OLP which include topical corticosteroids (TCSs), topical calcineurin inhibitors (TCIs) retinoids, photochemotherapy; amitryptaline; thalidomide; amlexanox and traditional medicines such as curcumin, selenium-ACE combined with itraconazole, glycyrrhiza glabra and aloe vera. But the exact treatment is still unknown. Objective: To compare the efficacy of Dexamethasone, Doxycycline, Nystatin and Promethazine cocktail with Triamcinolone as topical treatment of OLP Subjects and Methods: 40 patients of symptomatic OLP will be randomly divided in to study and control group. Study group will be given a cocktail containing dexamethasone, doxycycline, nystatin and promethazine and will be advised to rinse with 1 and half teaspoon of this cocktail 3 times a day for 2 minutes for the period of 8 weeks. Study group is also advised to apply an orabase containing 0.1% triamcinolone on lesions 3 times a day for the period of 8 weeks. The control group will be advised to apply only triamcinolone orabase 3 times a day for 8 weeks.
Oral Lichen Planus (OLP) is an inflammatory disease of mucosal and skin with unknown etiology. The prevalence rate in England is reported to be between 1-2.4%. OLP contributed to around 40% of all visits or 1,200 appointments in 2014 at the Eastman Dental Hospital. Pain, discomfort, long-standing use of medications, lesion recurrence and adverse side effects of therapy are commonly associated with OLP, eventually leading to a significant reduction in a patient quality of life. In addition, there is also increased risk of developing oral cancer in patients with OLP. The current gold standard treatment for OLP is corticosteroid, which can result in adverse side effects including increased risk of infections and skin cancer, reduced systemic immune system, and hepatotoxicity with long-term usage. Alternatively, a probiotic food supplement, VSL#3, has shown evidence of been able to induce and maintain remission in Inflammatory Bowel Disease (IBD), with no adverse effect a part than bloating, reported. Additionally, a preliminary report shown that probiotics treatment in Behcet's disease and Recurrent Aphthous Stomatitis (RAS) lesion resulted in reducing the number of oral ulcerations and subjective relief of oral discomfort. Investigator designed a clinical trial with 30 participants allocated to one of two interventions, VSL#3 or placebo. Individuals with biopsy-confirmed OLP who experience painful symptoms will be recruited from a single site research site (Eastman Dental Hospital (EDH)). Either the active VSL#3 or the placebo, provided by Ferring Pharmaceuticals Limited, will be consume twice a day over a 30 days period. Questionnaires that will determine pain levels, disease activity and quality of life will be completed before the study begins, on days 15, 30 and 30 days after the last supplement intake. In addition saliva and blood samples will be taken before therapy begin, at 30 days of therapy, and 30 days after the last supplement intake. The levels of pro-inflammatory cytokines and the oral microbiota will be investigated using these samples. A blinded clinician will assess the clinical effects between groups of active VSL #3 and placebo and the results will analyze by statistician.
Abstract Objective: To study the diagnostic efficiency of Rose Bengal with Toluidine blue in detecting the biopsy sites and thus establish an accurate diagnosis in oral premalignant lesions. Materials and method: In our study 27 patients with 41 lesions were included. Since one patient had not quit the habit in the two weeks following initial examination and another lesion disappeared in the waiting period, 2 patients (3 lesions) were not included in the study. Out of 38 lesions diagnosed based on clinical criteria, 32 were leukoplakia, 5 lichen planus and 1 SCC. After initial examination they were subjected to Rose Bengal and Toluidine blue stain. If stained positive they were subjected to biopsy.
