Ameloblastomas are benign odontogenic tumors that can eventually mimic the clinical and radiological features of apical periodontitis. The aim of the present study was to evaluate the clinical, radiological and histological characteristics from a series of ameloblastomas mimicking apical periodontitis diagnosed in a 14-year period.
all cases histologically diagnosed as ameloblastomas from 2005 to 2018 presenting a clinical diagnosis of periapical lesion of endodontic origin were selected for the study. Clinical, radiological and histological characteristics from all cases were tabulated and descriptively and comparatively analyzed.
Twenty cases composed the final sample, including 18 solid and 2 unicystic ameloblastomas. Mean age of the affected patients was in the fifth decade with predilection for males (72%). The most common anatomical location was the posterior mandible (55%) and most cases presented a radiolucent unilocular (80%) well-defined (95%) image. Most cases were asymptomatic, but the presence of local swelling and bone cortical rupture were common.
Ameloblastomas mimicking periapical lesions of endodontic origin are mostly diagnosed in adult males as well-defined radiolucent unilocular lesions producing local swelling and bone cortical rupture.
成釉细胞瘤是一种良性牙源性肿瘤，最终可能会模仿根尖周炎的临床和影像学特征。本研究旨在评估在 14 年期间诊断为根尖周炎的一系列成釉细胞瘤的临床、放射学和组织学特征。
选择了 2005 年至 2018 年期间所有经组织学诊断为成釉细胞瘤、临床表现为牙髓来源根尖病变的病例进行研究。对所有病例的临床、放射学和组织学特征进行了列表，并进行了描述性和比较性分析。
最终样本包括 20 例，其中 18 例为实性成釉细胞瘤，2 例为单囊型成釉细胞瘤。受影响患者的平均年龄在 50 岁左右，男性居多（72%）。最常见的解剖部位是下颌后区（55%），大多数病例表现为边界清晰的透亮单房性（80%）影像。大多数病例无症状，但常见局部肿胀和骨皮质破裂。
表现为牙髓来源根尖病变的成釉细胞瘤大多在成年男性中诊断，表现为边界清晰的透亮单房性病变，引起局部肿胀和骨皮质破裂。
