Ameloblastomas are benign asymptomatic intraosseous lesions that affect the bones of the maxillomandibular complex, interfering both in function and facial esthetic appearance. A 14-year-4-month-old girl was referred by her clinician complaining her anterior teeth were crooked and inclined forward. The lower left mandibular tooth presented with increased pericoronal space compatible with dentigerous cyst.
The aim of this report is to relate a case of unicystic ameloblastoma with conservative treatment and with indication for orthodontic treatment. The conservative therapy was performed and the lesion had been completely removed. The need for radiographic and clinical follow-up for up to 10 years, initially performed every 6 months during the first 2 years and afterwards annually, in addition to the risk of late recurrence were explained for patient and her guardian.
The histopathologic exam of the surgical tissue provided the final diagnosis of ameloblastoma, as the lesion had not presented in its classical form and in atypical locations, as in this case involving a tooth that had not yet erupted.
成釉细胞瘤是一种良性、无症状的颌骨内病变，影响上颌骨和下颌骨复合体的骨骼，同时影响功能和面部美观。一位 14 岁 4 个月大的女孩因她的前牙不齐且向前倾斜，被她的临床医生转诊。左下下颌牙齿出现了与含牙囊肿相吻合的牙囊周围空间增大。
本报告旨在介绍一例保守治疗的单囊型成釉细胞瘤病例，并提示需要进行正畸治疗。进行了保守治疗，病变已完全切除。向患者及其监护人解释了进行长达 10 年的影像学和临床随访的必要性，最初在前 2 年内每 6 个月进行一次，之后每年进行一次，此外还存在晚期复发的风险。
手术组织的组织病理学检查提供了成釉细胞瘤的最终诊断，因为该病变没有呈现出典型的形态，也没有出现在典型的位置，就像本例涉及一颗尚未萌出的牙齿一样。
