Rat odontogenic tumors associated with disturbed tooth eruption

Abstract

Most odontogenic tumors occurring in rats have the appearance of immature or mature odontomas. The present brief paper describes two spontaneously occurring odontogenic lesions in rats; both had the appearance of complex odontomas. One was associated with a lesion that had the appearance of an odontogenic fibroma; the other occurred concomitant with a lesion that had the appearance of a cementoblastoma. Their possible relationship with disturbed eruption due to malocclusion is discussed.
