Abstract
Pyknodysostosis is an autosomal-recessive disorder of osteoclast dysfunction causing osteosclerosis, with associated maxillofacial anomalies. Multidetector CT with multiplanar and 3D reconstruction illustrated the pathologic findings in this case. Abnormalities included multiple retained deciduous teeth, unerupted teeth with associated follicles, an irregularly expanded alveolus and body of the mandible, and an obtuse mandibular angle. Volume-rendered imaging better delineated the irregular dentition, with crowding and retention of deciduous teeth.
摘要
致密性骨发育不全是一种常染色体隐性破骨细胞功能障碍性疾病，可导致骨硬化，并伴有颌面部异常。多排螺旋CT结合多平面和三维重建显示了该病例的病理表现。异常包括多个乳牙滞留、伴有牙囊的未萌出牙齿、下颌骨牙槽和体部不规则扩大以及下颌角钝圆。容积再现成像能更好地描绘不规则牙列，以及乳牙的拥挤和滞留情况。
