Objective: To compare different histological variants of ameloblastoma in terms of proliferative activity, to use histochemical methods of AgNORs and to classify different types of ameloblastomas. Place and Duration: In the Department of Pathology of Services Hospital Lahore for two year duration from January 2017 to December 2018. Methods: A cross-sectional study of 50 surgical specimens collected using a non-probability sampling technique of ameloblastoma was selected. All ameloblastoma

All selected samples were fixed in 10% neutral formalin and treated with hematoxylin and eosin at the Pathology Department for initial selection. These sections were initially reviewed by two pathologists by examining several hematoxylin and eosin-stained tumor slides (mean, 2.5 slides per tumor, range, 2-8), and were diagnosed with consensus. Results: The mean age of the patients was 39.9 ± 15.1 between 12 and 80 years. There were 37 (76%) males and 13 (25%) females in this study. When AgNOR's mean values were examined in 4 study groups, the mean value of AgNOR was higher for acanthomatous, ie 3.15 ± 0.30 and the follicular variant was lower for 1.39 ± 0.82. Comparison of MAgNOR was performed using ANOVA and mean mAgNOR was different in 4 groups and p value was calculated as <0.001. In the histological variants, the association of mAgNOR 3.0 value was observed when the association of threshold value was observed (p = 0.003). Patients with MAgNOR> 3.0 were only in the desmoplastic and acanthomatous groups. Similarly, the relationship of pAgNOR> 5.0 was significant with histological variants (P <0.001). All desmoplastic and acanthomatous cases had pAgNOR> 5.0. The size relationship was significant [...]
