暂无%X Regional odontodysplasia (ROD) is a rare developmental anomaly with distinctive clinical, radiographical and histological findings, affecting both primary and permanent dentitions. The teeth with ROD have an atypical morphology and are usually discolored, with either delayed eruption or complete failure to erupt. Radiographically, the affected teeth have a "ghostly" appearance, with marked radiolucency and decreased radiodensity, showing a thin outline of enamel and dentin, which appear hypomineralized histologically, with poorly structured dentinal tubules and enamel prisms. Calcifications are frequently found in the pulp chambers of the affected teeth. This case report discusses a three-year-old girl who presented with ROD in her mandible as well as the clinical and radiographical features, and treatment of the condition.
