Active clinical trials for "Lichen Planus, Oral"

Dental health professionals have a responsibility to perform routine intra- and extraoral inspection on their patients for detecting abnormalities. As dental hygienists (DH) and dentist (D) often see their patients on a regular basis, they have the opportunity to provide this screening, and at an early stage detect abnormalities.

Due to the change of life style, the incidence of oral cavity mucous membrane disease increased.In this study，been done a large number of pre-clinical practice and some experimental studies， based on the application of metabolomics technology to ultra-high liquid-mass spectrometry metabolomics analyzer as the core means， The metabolism of pattern recognition and combination of modern analytical techniques to measure blood and urine of patients with OLP-specific clearance of endogenous metabolites，and after the intervention of moss drink endogenous metabolites in the body as a whole group of. At the same time， the use of flow cytometry,，ELISA， immunohistochemistry and other modern technology, research OLP patients using clean moss drink before and after treatment of local lesions and peripheral blood CD4 +，CD8 + lymphocytes，Th1 cytokines (IFN-γ， TNF-α)， Th2 cytokines (IL-4，10) the dynamic changes. From metabolomics， cellular immunology， inflammation mechanism perspective of local OLP lesions， peripheral blood and changes in endogenous metabolites in the process,，in-depth study of traditional Chinese medicine to drink clean moss multi-component multi-target treatment of this disease mechanism， is widely used in traditional Chinese medicine treatment of OLP provide a theoretical basis for the promotion of Chinese medicine Qingxian Yin in the oral mucosal disease in the application， effectively solve clinical practice problems.

To investigate the role of Vitamin D (VD) deficiency as a risk factor for the development and malignant transformation of Oral lichen planus (OLP) taking into consideration sex, dietary habits, sun exposure, socioeconomic status and psychological factors.

60 individuals were subdivided into 2 groups, 30 patients with oral lichen planus, 30 control individuals. Expression of miRNA-138 and cyclin D1 were evaluated in oral mucosa utilizing Quantitative real-time polymerase chain reaction and immunohistochemistry.

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.

Chronic erosive gingivitis is a syndrome (CEGS) that combines severe gingival inflammation and gingival erosion. The term "desquamative gingivitis" is often used in the literature to define chronic erosive gingivitis. However, this definition is inappropriate because the pathophysiological process at the origin of this gingival disease does not induce a desquamation but rather a loss of gingival substance, namely erosion, concerned wholly or in part of the gingival epithelium. In most clinical situations, chronic erosive gingivitis is an oral manifestation of a general disease with immune dysfunction. The most frequently described diseases are gingival lichen and autoimmune bullous diseases (AIBD). In 2018, as part of a monocentric study, we were the first to detail an original papillary gingival biopsy protocol, non-iatrogenic, perfectly suited to the anatomopathological examinations necessary for the diagnosis of AIBD gingival expression. The CEGS early detection by odontologists avoid delayed diagnosis and allows patients to be referred to the closest AIBD reference center. Hypothesis/Objective A bicentric study was conducted, to evaluate the clinical relevance of this protocol, including the differential diagnosis of the CEGS. Research was supplemented by carrying out a systematic review of the literature to compare the contributive capacity diagnostic of the papillary biopsy technique with other gingival sample methods (attached gingival tissue, mucosa). Method A retrospective bicentric observational study was conducted from October 2011 to July 2019, in two departments of oral medicine of two public hospitals in Paris (University Hospital - Bretonneau in Paris and Henri Mondor in Créteil; France). These two departments are specialized in the diagnosis and management of oral pathology; that of the Henri Mondor hospital is an AIBD reference center. The literature review was developed in accordance with PRISMA recommendations. It was conducted on Pubmed - MEDLINE and Cochrane Oral Health Group and included all existing publications from 1935 until August 2019. A manual search of publications from the unpublished literature was also conducted.

Oral lichen planus (OLP) is one of the most common mucosal diseases with autoimmune etio-pathogenesis with involvement of various cytokines similar to psoriasis.It generally occurs more commonly in females, in a ratio of 3:2. prolactin (PRL),It is a peptide hormone that has a role in autoimmune related diseases like systemic lupus erythematosus and , rheumatoid Artheritis. The role of PrL in OLP pathogenesis was never investigated.the aim of this study is to investigate the expression of PRL receptors in tissue biopsies of OLP patients.

The lichen planus is a mucocutaneous disease of unknown etiology with an incidence of 1-2%, that affects in 30-70% of cases either the mucosa of the mouth, or partly in combination with infection of the skin, the oral with his known premalignant potential in up to 2-3% predisposed to the development of an oral squamous cell carcinoma.In rare cases, there is also an manifestation of the lining of the esophagus, which can then be associated with symptomatic strictures of the esophagus. The value of moreover increasingly established endoscopic imaging procedures are investigated as well as data of the natural long-term outcome in esophageal lichen planus infestation especially in view of malignant transformation.

This study aims to identify the accuracy of DNA integrity index in differentiating between oral premalignant lesions and oral cancer.

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.
