Mandibular infected buccal cysts occur on the buccal and distal aspects of the roots of partly or fully erupted mandibular molars with vital pulps. In the present investigation six cases associated with mandibular first and second molars were studied. The cysts were lined with a non-keratinised squamous epithelium with a mixed inflammatory cell infiltrate in the connective tissue. The clinical and microscopic features were similar to those of previously reported paradental cysts. The inflammation always present in these cysts may have an important role in their pathogenesis. It may induce periodontal pocketing, which may lead to hyperplasia and cyst formation in adjacent odontogenic epithelium, which may be either remnants of the reduced enamel epithelium or cell rests of Malassez.
下颌感染性颊囊肿发生于部分萌出或完全萌出且牙髓活力正常的下颌磨牙牙根的颊侧和远中面。在本研究中,对6例与下颌第一和第二磨牙相关的病例进行了研究。囊肿内衬非角化鳞状上皮,结缔组织中有混合性炎性细胞浸润。其临床和显微镜下特征与先前报道的牙周囊肿相似。这些囊肿中始终存在的炎症可能在其发病机制中起重要作用。它可能诱发牙周袋形成,进而导致相邻牙源性上皮增生和囊肿形成,这些上皮可能是釉质上皮缩余的残余物或马拉瑟上皮剩余细胞。
