An unusual case of dens evaginatus in a 22-year-old man is reported. The involved tooth was the right upper second premolar which appeared to have been segregated into coronal and apical segments during the disease process. Although abscess formation was noted in the coronal portion, continuing secondary dentin deposition was found over the displaced apical segment. The pathogenesis of this unusual dentinal bridge formation is proposed based on the microscopic and radiographic findings.
报告了一例22岁男性的罕见的畸形中央尖病例。患牙为右上颌第二前磨牙，在病程中似乎已被分为冠部和根尖部。尽管在冠部发现有脓肿形成，但在移位的根尖部发现有继发性牙本质持续沉积。根据显微镜和影像学检查结果，提出了这种不寻常的牙本质桥形成的发病机制。
