Odontogenic tumors represent a spectrum of lesions ranging from malignant (rare)and benign neoplasm's to dental hamartomas, all arising from odontogenic residues i.e. odontogenic epithelia and/ or ectomesenchyme with variable amounts of dental hard tissues formed generally in the same sequence as in normal tooth development. They comprise an unusually diverse group because odontogenesis is a complicated process in which cells in the various stages of differentiation participate in a complex predetermined manner.
