Unilateral odontodysplasia with ipsilateral hypoplasia of the mid-face. A case report

A ten-year-and-1-month-old patient with regional odontodysplasia in the right maxilla is presented. The tooth malformation extended as far as the midline. The teeth 654321 + were markedly affected and exhibited a small indistinctly mineralized border with the 7 + being somewhat hypermineralized. The affected teeth in the respective quadrant had incomplete, retarded root formation. In addition, the patient had an obvious hypoplasia of the zygomatico-maxillary complex on the right. Ischaemia due to insufficient blood supply by the maxillary artery on the right is considered to be a possible cause of the disturbance described, and this is discussed.
