Regional odontodysplasia: report of a case involving two separate affected areas.

The purpose of this study was to report in a 12-year old white child a rare clinical condition called regional odontodysplasia. The diagnosis was based on clinical and radiographic findings. Due to the patient's concern over appearance, the treatment involved extracting the affected teeth and subsequently placing partial removable prostheses, thus providing the patient better function and appearance. The teeth that were removed were examined histologically, both in routine preparation stained by hematoxyline and eosin, and in ground sections.
