Abstract
Regional odontodysplasia (RO) is a rare developmental anomaly involving both mesodermal and ectodermal dental components in a group of contiguous teeth. It affects the primary and permanent dentitions in the maxilla and mandible or both jaws. Generally it is localized in only one arch. Clinically, affected teeth have an abnormal morphology, are soft on probing and typically discolored, yellow or yellowish-brown. Radiographically, the affected teeth show a “ghostlike” appearance. This paper reports the case of an 11-year-old girl presenting this rare anomaly on the right side of the maxillary arch. The primary maxillary right central, the lateral and the canine were found missing. The permanent teeth had a “ghostlike” appearance radio graphically. The treatment performed was rehabilitation with temporary partial acrylic denture and periodic controls. The presentation of this case adds valuable information to dentists to review special clinical and radiographic features of RO, which will facilitate the diagnosis and treatment of patients with this condition. Since the etiology of this dental anomaly is uncertain, a review of its probable etiologic factors is summarized to get a better understanding of its cause of occurrence.
