Abstract：
OBJECTIVE: To illustrate characteristic features of adenomatoid odontogenic tumour (AOT) on CBCT.
METHODS: The archived CBCT and panoramic radiographs of eight patients histopathologically diagnosed as AOT were analysed. The radiographic features displayed on both radiographic images were carefully described and compared.
RESULTS: All eight AOT cases presented as unilocular and well-demarcated lesions on both CBCT and panoramic images. CBCT images displayed three-dimensional interpretation of AOT lesions, especially the detailed intralesional radiopacities. Numerous discrete radiopaque foci scattered in the lesion with evident contrast to the radiolucent background could be considered as one of the characteristic features of AOT on CBCT.
CONCLUSIONS: Compared with panoramic radiography, CBCT seems to possess better potential in diagnosing AOT.

摘要：
目的：说明CBCT上腺瘤样牙源性肿瘤（AOT）的特征性特征。
方法：分析8例经组织病理学诊断为AOT的患者的CBCT和全景X线片。仔细描述并比较了两个射线照相图像上显示的射线照相特征。
结果：所有8例AOT病例在CBCT和全景图像上均表现为单眼和边界清晰的病变。CBCT图像显示AOT病变的三维解释，尤其是详细的病灶内射线不透明性.许多离散的不透射线的焦点散布在病变中，与射线可透背景形成明显对比，可以认为是CBCT上AOT的特征之一。
结论：与全景摄影相比，CBCT在诊断AOT方面似乎具有更好的潜力。
