70 patients with suspicious oral lichen planus; atrophic and bullous erosive forms will be included. The blood samples will be drawn between 08:00 and 09:00 AM, after a fasting period of 12 hours, and analysis were performed within 2 hours of the sampling. The MPV and other hematologic parameters will be measured in a blood sample. A surgical biopsy will be performed for histopathological assessment.
This study aims to identify the accuracy of DNA integrity index in differentiating between oral premalignant lesions and oral cancer.
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.
The aim of this study was to compare the efficacy of PBM (660nm) and corticosteroid therapy with clobetasol propionate 0.05% in the treatment of OLP. This is a protocol for a randomized, controlled, double blind clinical trial. Fourty-four patients will be randomized in two experimental groups. Control group will be treated with clobetasol propionate 0.05% for 30 consecutive days and with placebo PBM twice a week. The experimental group will be treated with placebo gel for 30 consecutive days to mask the treatment and patients will receive PBM twice a week during 1 month (laser λ = 660±10 nm; power 100mW; radiant energy 177J/cm2; 5-s exposure time per point and 0.5J of energy per point. The primary variable (pain) and the secondary variables including clinical scores and functional scores as well as patient anxiety and depression (The Hospital Anxiety and Depression Scale-HADS), will be evaluated at the baseline, once a week during treatment and after 30 and 60 days of follow up. Evaluation of clinical resolution will be performed at the end of the treatment (30 days). Evaluation of recurrence will be performed after 30 and 60 days of follow up. Serum and salivary levels of IL-6, IL-10, IL-1β, INF-γ and TNF-α will be evaluated at baseline and at the end of treatment (30 days). Quality of life will be evaluated by OHIP-14 questionnaire at baseline, at the end of treatment and after 30 and 60 days of follow up. The chi-square test, Student's t-test and ANOVA will be used and the level of significance of 5% will be considered (p < 0.05).
After signing the informed consent, the participant will be allocated to either intervention or control group, then each participant in the intervention group will receive intralesional injections of platelet rich plasma extracted from their own blood in each visit as following: 1. 12 ml of blood will be assembled from the veins of antecubital fossa 2. PRP preparation will be done according to Mostafa et al., 2013 3. 0.5 ml of PRP will be injected per 1 cm2 of ulcerated mucosa The second group will receive triamcinolone acetonide 40 mg injected 1 ml per 1 cm2 of ulcerated mucosa Both groups will receive a total of 4 injection, the injections will be carried out once a week. Pain, lesions size and remission time are the outcomes will be assessed using a numerical rating scale (Seymour, 1982), clinical score according to Thongprasom et al., 1992 and binary scale for remission time according to Conrotto et al., 2006, respectively. Assessment of the outcomes will be carried before the trial (baseline records) and before receiving the treatment in each visit by the primary investigator (H.A.) and the blinded assessor (Dr. A.W.) separately. Each participant will have a total of 11 visits during the trial, 5 visits will be once every week during the trial and every 2 weeks for 3 months treatment free.
