Study of Ki67 in odontogenic benign tumors

The aim of the present study was to investigate Ki67 expression level and measure cell proliferation index (Ki67) in odontogenic benign tumors. This an analytical cross-sectional sampling non-probabilistic with exhaustive recruitment including all biopsy or surgical excision specimen immunohistochemistry performed on histological sections paraffin-fixed tissues 3µ thickness (MM1) monoclonal antibody. studied variables were sociodemographic, clinical histopathological. data have been analysed SPSS 20.0 software. : Ameloblastoma represented 50.9% cases cemento-osseous dysplasia 36.4%. Among 28 ameloblastoma cases, 15 (53.6%) plexiform type, 7 (25%) follicular type 6 (21.4%) unicystic type. percentage labelled cells less than 1% 74.6% (n=41) tumors equal 5% 12.7% (n=7) cases. A law labelling found 87.3% (n=48) tumours a negative had weak low epithelial index. could not therefore be used as predictive biomarker tumor risk recurrence
