In recent years, it has been suggested that three may be arelation between lichen planus and the hepatic diseases, but this relation is ques tionabl. Some researchers recmommend that patients with lichen planus should be observed carefully for an underlying hepatic disease. In our study, AST and ALT levels of 35 patients who are diagnosed clinically and histopathologically as having oral lichen planus are measured, and they are investigatid as to the possibility of Hepatitis B. Ic has been determined that serum AST and ALT levels have been within normal limits and no significant difference has been established as compared to the control group. Hepatitis B antigens are found to be negative.
