title: Multiple enamel pearls in two siblings detected by volumetric computed tomography.
abstract: A rare case of multiple enamel pearl formation is presented involving the maxillary molars in two siblings incidentally recognized during volumetric CT examination. Although the pathogenesis of ectopic enamel formation is not known, possible mechanisms to account for this phenomenon are discussed in the context of current knowledge regarding root genesis. The radiographic presentation of enamel pearls and its clinical significance is also discussed. The observation of multiple enamel pearls in two siblings raises the possibility of a hereditary association in the formation of enamel pearls.
