A case of a compound odontoma caused delayed eruption of a central incisor in the maxilla is presented with clinical, radiographic, and microscopic findings. The odontoma was surgically removed and microscopic examination showed a lot of crown-like structures in a very irregular form, some of which were fused to each other at their apical parts. Enamel and pre-enamel were totally abnormal, whereas the inside of the pulp chamber tissue did not present any histological sign of functional tissue. The most homogeneous tissue was dentin. The removal of the odontoma was followed by a rapid eruption of the impacted central incisor.
本文报告一例因复合性牙瘤导致上颌中切牙萌出延迟的病例，并给出临床、影像学及显微镜检查结果。该牙瘤通过手术切除，显微镜检查显示有许多形态极不规则的冠状结构，其中一些在根尖部分相互融合。釉质和前期釉质完全异常，而牙髓腔组织内部未呈现任何功能组织的组织学迹象。最均质的组织是牙本质。牙瘤切除后，受阻的中切牙迅速萌出。
