Epithelium-lined cysts of the jaw can be either odontogenic or non-odontogenic. Cysts that exhibit keratinization of their epithelial lining are called odontogenic keratocysts. They compose approximately 8% of all odontogenic cysts. There is a frequent association with unerrupted teeth, and a high incidence of occurrence of keratocysts in the multiple basal cell nevus syndrome. The significance of odontogenic keratocysts is their high potential for recurrence after their removal. There is no specific radiographic feature, however, that distinguishes them from non-keratinized odontogenic cysts. High resolution computed tomography (CT) studies can exquisitely determine the extent of these lesions and pinpoint areas of cortical breakthrough as well as involvement of the teeth. This information is invaluable in surgical planning for excision of these lesions.
颌骨内衬上皮的囊肿可为牙源性或非牙源性。上皮内衬出现角化的囊肿称为牙源性角化囊肿。它们约占所有牙源性囊肿的8%。常与未萌出牙齿相关，且在多发性基底细胞痣综合征中角化囊肿的发生率较高。牙源性角化囊肿的重要性在于其切除后复发的可能性很高。然而，没有特定的影像学特征能将它们与非角化牙源性囊肿区分开来。高分辨率计算机断层扫描（CT）研究可以精确确定这些病变的范围，查明皮质突破区域以及牙齿受累情况。这些信息对于这些病变切除的手术规划非常宝贵。
