The dentigerous (follicular) cyst is recognized as one of the most common lesions of the jaws. Clinical, radiographic, histologic, and prognostic characteristics are well established for medium to large pericoronal cysts that are lined by nonkeratinized stratified squamous epithelium. However, it can be difficult, if not impossible, to distinguish between a small dentigerous cyst and a large dental follicle despite the availability of both radiographic and histologic information. Epidemiologic data derived from a comparative study of 1662 dentigerous cysts and 824 dental follicles showed considerable overlap in age distribution and site predilection and were therefore of minimal use in reaching a final diagnosis. At present, it appears that identifying a cystic cavity at the time of surgery may be the only reliable way to arrive at a definitive diagnosis when radiographic and histologic features are insufficient to distinguish between a small dentigerous cyst and a large dental follicle.
含牙（滤泡）囊肿被认为是颌骨最常见的病变之一。对于由非角化复层鳞状上皮衬里的中到大的冠周囊肿，其临床、影像学、组织学和预后特征已得到充分确立。然而，尽管有影像学和组织学信息，区分小的含牙囊肿和大的牙滤泡可能很困难，甚至不可能。一项对1662例含牙囊肿和824例牙滤泡的比较研究得出的流行病学数据显示，年龄分布和部位偏好存在相当大的重叠，因此在做出最终诊断时用处不大。目前，当影像学和组织学特征不足以区分小的含牙囊肿和大的牙滤泡时，在手术时识别出囊腔似乎可能是做出明确诊断的唯一可靠方法。
