[The relationship between lichen ruber planus orale, hepatopathies and hypersensitivity to the components of dental restorations].

A group of patients with lichen planus, a pathology affecting the cutis and mucosa which may affect the oral cavity, were studied. All patients underwent laboratory tests to assess hepatic function. Prick tests, using a series of haptens found in materials used in dental reconstruction work, were also performed in 53 patients who possessed dental prostheses. The statistically significant correlation between lichen planus, especially in its erosive form, and hepatic damage is underlined. However, the correlation between sensitivity to the haptens contained in materials for dental reconstruction work and lichen planus was not significant.
