Different researchers have carried out different methods to assess the grading of the different types of ameloblastomas of which one of the methods which assess the proliferative activity of ameloblastoma are argyrophilic nucleolar organizer regin (AgNOR) which stains the proteins with silver stain which is associated with active nucleolar organizer regions (NOR|), these are DNA loops that transcribe to ribosomal RNA directs protein synthesis and ribosomal formation.
