Background A possible association between oral lichen planus (OLP) and chronic hepatic disease has been found in some populations, although this is probably geographically influenced. In 1997 a new hepatotropic virus, transfusion transmitted virus (TTV), was identified but has not been studied in relation to OLP. Objective The present investigation evaluated the genoprevalence of TTV DNA in the sera of British and Italian patients suffering from OLP using two different sets of primers to identify TTV subgenomic DNA. Methods Study groups comprised 40 adult subjects (21 British, 19 Italian) with OLP. For each country, two control groups, a disease‐control group and a healthy‐control group, were included. The presence of TTV DNA in the sera of patients and control subjects was assessed using two different polymerase chain reactions (PCR) and DNA sequence analysis. Results Statistical analysis did not reveal evidence of any association between TTV infection and OLP or country of residence. Conclusion An association between TTV and OLP is unlikely.
