title: p53 expression in oral lichenoid lesions and oral lichen planus.
abstract: The aim of this article was to compare the expression of p53 protein in oral lichen planus (OLP) and oral lichenoid reaction (OLR). The study population consisted of 65 patients--31 diagnosed with OLP and 34 with OLR. The results showed more p53 positive cases in the OLP group than in the OLR group. However, the difference between the 2 groups was not statistically significant (P = 0.114). The most common immunolocalization was observed at the basal cell layer. Due to the chance of potential future malignancy, follow-up for all cases is recommended.
