A case of circumferential dentigerous cyst is presented, with a review of the literature. This lesion occurs when the tooth is exfoliated through the cystic epithelium surrounding a crown, so that the cyst remains within the cervical third. When these teeth are extracted without previous diagnosis, the cyst could become residual. In all dentigerous cyst, the microscopic features must be determined, since some reports mention their eventual transformation in an ameloblastoma or, even worse, in a squamous-cell carcinoma.
本文报告一例环行含牙囊肿病例，并对相关文献进行综述。当牙齿通过围绕牙冠的囊性上皮脱落时，就会发生这种病变，从而使囊肿保留在牙颈部三分之一处。如果在未进行前期诊断的情况下拔除这些牙齿，囊肿可能会残留。在所有含牙囊肿中，都必须确定其微观特征，因为一些报告提到它们最终可能转变为成釉细胞瘤，甚至更糟的是转变为鳞状细胞癌。
