Bilateral mandibular regional odontodysplasia with vascular nevus.

Odontodysplasia is a rare clinicopathologic condition that has a variety of expressions, including a range of tooth coloration, formation of hypoplastic enamel affecting one or multiple teeth, bizarre radiographic appearance, and delayed eruption of teeth. An unusual case is presented of bilateral regional odontodysplasia associated with a vascular nevus of the face and neck. A review of the etiology with emphasis on the "local circulatory disease" theory is presented.
