Oral Lichenoid Contact Reaction to a Complete Denture
Journal Title: Indian Journal of Dental Advancements - Year 2015, Vol 7, Issue 4
Abstract
Oral lichenoid lesions (OLLs) or oral lichenoid reactions (OLRs) share common clinical and histological features to oral lichen planus (OLP). OLRs have sometimes been considered as part of OLP, and have also been described as contact allergies, or contact lesions. Local allergic contact hypersensitivity, termed as oral lichenoid contact reaction (OLCR) though uncommon, have been reported as a local tissue response to a variety of dental materials such as restorative materials, impression materials and dentures. Oral lichenoid contact reactions share common clinical and histological features to oral lichen planus (OLP), which is an auto immune disorder exaggerated in the oral cavity. Lesions of OLCR in relation to dental acrylic prosthesis are located in apposition or in near proximity to the denture base, and lesions are limited to such sites of contact. This article presents a rare case of oral lichenoid contact reaction to acrylic denture base. The lesion was initially thought to be a soft tissue fibroma due to chronic denture irritation. The definitive diagnosis was completely based on the histological analysis of the tissue sample, which confirmed the typical lichenoid characteristics of the lesion.
