The Cytology of Benign Oral Lesions.

Oral lichen planus and oral lichenoid lesions; a critical appraisal with emphasis on the diagnostic aspects.

Oral lichen planus (OLP) has a prevalence of approximately 1%. The etiopathogenesis is poorly understood. The annual malignant transformation is less than 0.5%. There are no effective means to either predict or to prevent such event. Oral lesions may occur that to some extent look like lichen planus but lacking the characteristic features of OLP, or that are indistinguishable from OLP clinicall...

Oral manifestations of dermatologic disease: a focus on lichenoid lesions.

Lichenoid changes in the oral mucosa can be encountered in a wide range of lesions with varied etiologies including immune-mediated disorders, reactions to systemic medications and to dental materials. Dysplasia of the oral cavity can exhibit a lichenoid histology, which may mask the potentially cancerous component. Another unusual clinical disease, proliferative verrucous leukoplakia, can ofte...

Oral lichenoid lesions and allergy to dental materials.

BACKGROUND Dental materials, oral hygiene products and food additives may cause contact allergic reactions in the mouth with varied clinical presentation. Oral lichenoid lesions (lichen planus-like lesions) can be induced by hypersensitivity to dental restorative metals, acrylates, flavorings and other substances. AIM The aim of this study was to demonstrate contact allergy to dental material...
