The etiology of OLP is unknown, viralantigens (for example EBV) have been proposed as etiologic agents. OLP may get transformation to malignancy soresearch on the presence of these in OLP lesions seems to be necessary. The aim of this study was to evaluate EBVexpression immunohistochemically in OLP.Materials and Methods: Tissue specimens of 30 formalin fixed, paraffin-embedded tissue Blocks histologicallydiagnosed oral lichen planus was performed to evaluate EBV expression.Results: Expression of EBV was detected in epithelium of (46.6%) in the study samples in (OLP). no statisticallysignificant correlation was found with clinical parameters except for a significantly higher expression in females.Conclusions: Epstein Barr viruses were present in considerable amounts in oral lichen planus. Taking into account thepotential of viruses in OLP proving or disapproving or etiological role of viruses in OLP is continuously need to beexamined in further studies
