Lichen planus and lichenoid reactions of the oral mucosa.
Oral lichenoid reactions represent a common end point in response to extrinsic agents (drugs, allergens), altered self-antigens, or superantigens. Oral lichen planus, a common and under-recognized inflammatory disorder, shares many clinical and histopathological features with oral lichenoid drug reaction and oral lichenoid contact reaction. Clinical presentation can vary from asymptomatic white...
متن کاملEvaluation of proliferation activity of oral lichen planus and oral lichenoid reactions using quantitative and qualitative analysis of AgNORs (Argyrophilic Nucleolar Organizer Regions)
Bachground & Aims: Oral lichenoid reactions (OLR) and oral lichen planus (OLP) are clinically and histopathologically similar but their therapeutic approach are different. Due to the presence of dysplasia in oral lichen planus which effects prognosis, the aim of study was the evaluation of proliferation activity of OLPs and OLRs and their subtypes. AgNOR technique that is inexpensive and easy...

متن کاملExpression of COX-2 and bcl-2 in oral lichen planus lesions and lichenoid reactions
UNLABELLED Oral lichen planus and lichenoid reactions are autoimmune type inflammatory conditions of the oral mucosa with similar clinical and histological characteristics. Recent data suggest that oral lichenoid reactions (OLR) present a greater percentage of malignant transformation than oral lichen planus (OLP). OBJECTIVE To compare the expression of bcl-2 and COX-2 in OLP and OLR. METHO...
متن کاملCorrelation between Clinical and Histopathological Findings in Oral Lichen Planus and Oral Lichenoid Reactions Based on Modified WHO Diagnostic Criteria
Background and purpose: There are clinical and histopathological similaritie between lichen planus (OLP) and oral lichenoid reactions (OLL) but they have different treatment approaches. The present study examined the correlation between clinical and histopathological findings in lichen planus and oral lichenoid reaction based on modified WHO diagnostic criteria in order to evaluate using these ...
