[A statistical epidemiological study of a possible correlation between serum transaminase levels and viral hepatic pathology markers and lichen planus orale].

The aim of the present study is to carry out a clinical-statistical research into a large number of patients suffering from oral lichen planus (LPO) and from different odontostomatologic pathologies. In both groups of patients serum transaminase values and eventual presence of hepatopathy viral markers were investigated in order to identify a possible correlation between the aforesaid parameters and LPO, considered in its various clinical forms (papular and erosive essentially). Results had showed a close association between hepatopathy and LPO, according to results of studies performed by other Italian and Spanish groups and differently from Anglo-Saxon authors: above all an increased incidence of C hepatitis in patients with lichen was observed. Furthermore our investigation is agreed in underlining the great importance to attach to erosive form of oral lichen, that seems to join to active chronic hepatitis most frequently than papular one.
