ABSTRACT

Regional odontodysplasia (RO) is a rare and nonhereditary dental malformation. It is a dental alteration ofunknown etiology, involving both mesodermal and ectodermal dental components, which is characterized byclinical, radiographic, and histologic features. The maxilla is more often involved than the mandible (especially the left side), and there is no racial predilection,but females are affected twice as often as males. The affected teeth are clinically hypoplastic and hypocalcified,presenting a“ ghost-like”appearance radiographically. The present case features a male patient aged 4 years and 6 months who was diagnosed with regional odontodysplasiain the maxilla on the right side, confirmed by clinical and radiographic examination, with a follow upof 5 years. Since teeth affected by RO have a poor prognosis due to the fragile tooth surface and open apices, the longtermtreatment strategy depends on periodic clinical and radiological observations.
