Abstract | OBJECTIVE: The present study aimed to assess the usefulness of argyrophilic nucleolar organizer regions ( AgNORs) as quantitative criteria in the diagnosis of odontogenic cysts and tumors. STUDY DESIGN: RESULTS: The findings showed a significant statistical difference among the 4 lesions (P <.001). Conventional and unicystic ameloblastomas had a significantly higher (P <.05) number of AgNORs than odontogenic keratocysts and dentigerous cysts. No significant differences were observed within each group of tumors or cysts. The number of AgNORs was also significantly higher (P <.005) in the nuclei of basal layer cells of the epithelial lining of keratocysts than in the nuclei of parabasal layer cells. AgNORs in conventional and unicystic ameloblastomas were smaller but more broadly distributed, which may indicate higher proliferative activity. CONCLUSION:
