RESUMO
Immuno-histochemical evaluation of CD34 in oral lichen planus (OLP) and Oral Submucous Fibrosis (OSMF) is of interest to dentist.20 specimens of normal oral mucosa (buccal mucosa/gingiva tissue) from patients who had extractions performed as part of orthodontic treatment comprised Group I, the control group. Group II comprised 30 individuals with a diagnosis of oral lichen planus. 30 OSMF cases with diagnoses is Group III. These 80 specimens were all given consideration when choosing for CD34immuno-histochemical staining. The CD34 was greater in all categories of OLP and OSMF when compared to normal controls. Maximum CD34 expression was observed in erosive OLP (147.41±17.60) followed by OSMF (116.01 ±11.72) and reticular OLP (105.01±11.62). Data was statistically significant (p<0.001).Immunohistochemistry of CD34 evaluation is a potential diagnostic marker for OLP and OSMF.
