The paradental cyst is an uncommon lesion associated with the permanent mandibular first or second molar in children just prior to tooth eruption. The purpose of this article is to present two cases of paradental cyst affecting the buccal aspect of permanent mandibular first molar of both young patients. We also discuss diagnosis, treatment and radiographic findings of the cases.
In both cases was made only the enucleation of cyst without extraction of the adjacent tooth. Lesional samples were sent for histopathologic analysis.
The histopathologic analysis of both cases, revealed a lining of hyperplastic, nonkeratinized squamous epithelium with heavy, dense inflammatory cell infiltrate in the epithelium and connective tissue wall. The histopathology associated with macroscopic and radiographic examination permitted the definitive diagnosis of a paradental cyst on the mandibular left first molar. A follow-up of 1 year was carried out in both cases and no recurrences was noted; in the first case was observed the correct eruption of the mandibular permanent left first molar.
A clinicopathologic correlation, incorporating the surgical, radiographic, and histological finding, is required to obtain the final diagnosis of paradental cyst. Today, the treatment of choice is simple enucleation and thorough curettage of the cyst without extraction of the involved tooth.
牙周囊肿是一种罕见的病变，与儿童恒牙萌出前的下颌第一或第二恒磨牙相关。本文旨在介绍两例影响两位年轻患者下颌第一恒磨牙颊侧的牙周囊肿病例。我们还将讨论这些病例的诊断、治疗及影像学表现。
两例均仅行囊肿摘除术，未拔除相邻牙齿。病变样本送去做组织病理学分析。
两例的组织病理学分析均显示，内衬为增生性、非角化鳞状上皮，上皮及结缔组织壁中有大量密集的炎性细胞浸润。结合宏观及影像学检查的组织病理学表现确诊为下颌左侧第一恒磨牙牙周囊肿。两例均进行了1年的随访，未发现复发；第一例中观察到下颌左侧第一恒磨牙正常萌出。
需要结合手术、影像学及组织学检查结果进行临床病理关联分析，以最终诊断牙周囊肿。目前，首选的治疗方法是单纯摘除囊肿并彻底刮除，而不拔除患牙。
