Regional odontodysplasia (RO) is an uncommon nonhereditary developmental anomaly of dental hard tissues derived from ectoderm and mesoderm. The condition is more common in females, may affect primary and permanent dentitions with the maxilla, involves twice as frequently as mandible. The exact etiology of RO is unknown. Diagnosis is usually made by clinical and radiographic findings, sometimes supplemented with histopathologic examination. Clinically, teeth are hypoplastic with surface pits and grooves, and have brownish or yellowish discoloration. On the radiograph, there is reduced radiodensity of enamel and dentin with a lack of contrast between them. In this article, we described a case of a 3½-year-old girl with RO. The left maxillary quadrant was affected. The patient also showed eruption failure. Treatment of RO is, to a great extent, individualized. As the condition was asymptomatic, the present case was managed conservatively.
