CARREIRA, Aline Semblano Dias et al. Regional odontodysplasia: case report in maxilla crossing the midline. RGO, Rev. gaúch. odontol. (Online) [online]. 2011, vol.59, n.1, pp. 135-139. ISSN 1981-8637.

Regional odontodysplasia is a rare, nonhereditary condition that affects the development of the enamel and dentin of the deciduous and/or permanent teeth. The etiology is still unknown. In general, this condition is diagnosed during routine radiographic assessments and many cases are mistaken for malformed teeth or odontomas. This condition affects twice as many females as males and is more common in the maxilla than the jaw. This condition is also called "ghost teeth" because the enamel-dentine border of the affected teeth cannot be distinguished in the radiograph and the pulp chambers are wide. Clinically, the teeth are brownish or yellowish. The present study reports an unusual case of maxillary regional odontodysplasia crossing the midline in a 4-year-old female. All deciduous and permanent teeth in the left side of the maxilla and the central incisors in the right side of the maxilla were dysplastic.
