Filter by: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 A manual search of publications from the unpublished literature was also conducted.
The principal research objective is to provide enhanced understanding of the cellular and molecular events important in the pathogenesis of Oral Lichen Planus to enable improved diagnosis and development of novel treatments for patients.
Lichen planus is an auto-immune, chronic inflammatory disease that affects mucosal and cutaneous tissue. Erosive and atrophic oral lichen planus (OLP) are difficult to manage because patients present with symptoms ranging from episodic pain to severe discomfort and they have the highest malignant transformation rate (MTR) amongst all the forms of OLP. Zinc is associated with regeneration of epithelium, wound healing and mediating T-lymphocyte function; all of which can lead to healing and re-epithelisation in the lesions of erosive OLP. Besides this, it also has anti-oxidant and anti-inflammatory properties, which lead to decrease in apoptosis and transformation into a malignant state. This study intends to evaluate the effect of oral zinc supplements as an adjuvant to the topical corticosteroid therapy in the treatment of OLP.
investigating the level of malondialdehyde (MDA) & nitric oxide (NO) in saliva in oral premalignant and malignant lesions in order to determine their diagnostic value for the malignant and potentially malignant lesions.
The aim is to investigate the influence of oral lichen planus on periodontal status of systemically healthy individuals.
There are currently no effective treatments for lichen planus pigmentosus (LPP) and erythema dyschromicum perstans (EDP). Tranexamic acid, which may downregulate pigmentation through a reduction in plasmin, has been shown to decrease pigmentation in patients with melasma, another pigmentary disorder. Given that LPP, EDP, and melasma are all disorders of pigmentation with dermal involvement, it is possible that tranexamic acid can also reduce pigmentation in LPP and EDP as well.
This study was conducted to estimate the hypothesis that the Pomegranate Extracts have no role in management of oral lichen planus
Background: Oral epithelial dysplasia (OED) is a condition with an increased risk of oral cancer. Due to the current changes in the factors associated with these diseases (because of human papillomavirus), it is expected that those who have no history of smoking or alcohol, young (<50 years old), and white male would be commonly affected. Those individuals require a higher need for information, preferred a more active role in decision-making, and have a longer lifespan than older individuals. There remain no detailed studies of whether the informational needs delivered to patients with OED met their needs or indeed what information such patient may wish. A few tools are available to evaluate the IN of patients with head and neck disorders. However, the items of these instruments were dedicated to a particular disease (e.g. cancer) and hence are not applicable to be used for OED. Project aims: To evaluate the psychometric properties of the Oral Epithelial Dysplasia Informational Needs Questionnaire (ODIN-Q), developed and revised in the preliminary work for the proposed study, in a cohort of patients with OED. Timescale: 19 months. Clinical significance: This questionnaire can be useful in clinical practice. It could help to meet the patient's information needs and plan educational interventions for those showing unmet needs.
Treatment of oral lichen planus is challenging. Diverse therapeutic modalities have been suggested, but a permanent cure is not yet available. In some oral lichen planus patients, topical corticosteroid alone is not sufficiently enough, thus it may require a supplementation to augment its effect. This trial will assess the effectiveness of vitamin E as a supplement in management of oral lichen planus.
The aim of the present investigation is to assess the clinical therapeutic effect of topical use of Coenzyme Q10 versus topical corticosteroid in management of symptomatic oral lichen planus and determine whether the effect, if any, was due to its antioxidant activity.
