Filter by: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.
Oral Lichen Planus (OLP) is an autoimmune, chronic inflammatory mucocutaneous disease characterized by pain and burning sensation. The major types of OLP are the following: reticular, atrophic, erosive-ulcerative, bullous and pigmentous form.Its etiology remains unclear. The presence of auto-cytotoxic T cell clones in the lesions suggests the role of autoimmunity. Numerous treatment options of OLP include topical and systemic agents depending on severity of lesions . Topical corticosteroids abide the mainstay of therapy,and are widely accepted as the primary treatment of choice.Hence this study is designed to evaluate and compare the clinical efficacy of topical Clobetasol 0.05% in orabase and Betamethasone 0.05% in orabase in combination with Clotrimazole 1% in the management of symptomatic Oral Lichen Planus.
The aim of this study was to examine molecular alterations on the protein level in lesions of oral lichen planus (OLP), oral squamous cell carcinoma (OSCC) and healthy mucosa. Global protein profiling methods based on liquid chromatography coupled to mass spectrometry were used, with a special emphasis on evaluation of deregulated extracellular matrix molecules expression, as well as on analyses of insulin-like growtg factor 2 (IG2F) and insulin-like growth factor 2 receptor (IGFR2) expression in healthy mucosa, OLP and OSCC tissues by comparative semiquantitative immunohistochemistry. Mass spectrometry based proteomics profiling of healthy mucosa, OLP and OSCC tissues (and accompanied histologically unaltered tissues, respectively) identified 55 extracellular matrix proteins. Twenty among identified proteins were common to all groups of samples. Statistically significant difference between final IGF2 and IGF2R IRS scores in favour to IGF2R may further corroborate the IG2FR antitumor role in OLP and OSCC where it acts as a negative regulator of IGF2 activity.
Oral lichen planus (OLP) is a T-cell mediated chronic immunological disease directed to a still unknown antigen. It is a mucocutaneous and a psychosomatic disorder, with unknown prevalence rate; however studies suggest an incidence of 0.02 to 0.22% among the Indian population. 75% of patients with cutaneous lichen planus also experience oral lesions and may be precipitated or exacerbated by psychosocial stressors. In conditions like pain, anxiety and stress, many metabolic and endocrine changes occur in the body, the most common effect of which is increased cortisol level in blood. This hormone is a 21-carbon corticosteroid secreted by adrenal cortex and regulates the metabolism of carbohydrates, fats, proteins and water. Also known as stress hormone, cortisol is a decisive index in stressful situations. This study is intended to correlate the serum cortisol levels with anxiety and depression in patients with symptomatic oral lichen planus. This study attempts to evaluate psychological anxiety and depression in oral lichen planus subjects using Hospital Anxiety and Depression Scale ( HADS) and correlating with their serum cortisol levels. To understand and explore the etiopathogenesis for better management of oral lichen planus.
This study evaluates the effectiveness of topical NAVS naphthalan in the treatment of oral lichen planus (OLP) and recurrent aphthous stomatitis (RAS). Half of participants with OLP and RAS will receive topical NAVS naphthalan in adhesive paste, while the other half will receive 0.05%-betamethasone dipropionate in adhesive paste. Our hypothesis is that NAVS could be efficient in the treatment of OLP and RAS, with effects comparable to that of topical steroids.
Glucosamine (GlcN) is an N-deacetyl amino sugar derived from the complete hydrolysis of chitosan with recently reported immunoregulatory capacity and anti-inflammatory effect and was administrated orally in osteoarthritis and atopic dermatitis therapy. Given the Oral lichen planus (OLP) T-cell-mediated pathogenesis; this drug seems to be a promising therapeutic option. The investigators compared clinical effectiveness of Glucosamine combined with two topical corticosteroid regimens to that of topical corticosteroid alone in symptomatic OLP and investigated therapeutic mechanism by examining treatment effect on expression of inhibitor kappa kinase alpha (IKKα) and interleukin-8 (IL-8) in OLP lesions.
The objective of this single center, 4-week, open label randomized, phase II study is to evaluate and characterize the tolerability and clinical effectiveness of dexamethasone 0.5mg/5ml solution in a mucoadhesive vehicle (Mucolox™) for the treatment of oral lichen planus.
