Mandibular anterior region is an uncommon site for occurrence of intrabony pathologies. Unilocular presentation of a lesion is again less common than multilocular appearance. Demographically, most lesions occur in middle to elderly age group. The study is designed to review the pathologies manifesting a combination of these rare demographic and radiological criteria.
A retrospective analysis of patients with anterior unilocular radiolucencies of mandible in young patients was done. Records of past 10 years were searched. There were a total of 17 patients. Their clinical history and radiographs were reviewed from the case files and correlated with histopathological examination of the lesion.
Nine different pathologies constituted the sample size of 17. A wide array of lesions was found to manifest similar signs and symptoms and radiographic findings namely ameloblastoma (three), adenomatoid odontogenic tumor (AOT, four), odontogenic keratocyst (OKC, three), ossifying fibroma (OF, two), idiopathic bone cavity (IBC, one), dentigerous cyst (DC, one), radicular cyst (RC, one), central giant cell granuloma (CGCG, one), and calcifying odontogenic cyst (COC, one).
Anterior mandible is a rare site for occurrence of intrabony pathologies. Majority of patients are females. Lesions acquire large size before they are detected. Growth occurs more in length than in width. Root resorption is not uncommon and root displacement is almost a consistent feature.
下颌前部区域是骨内病变发生的罕见部位。病变呈单房表现又比多房表现少见。从人口统计学角度来看,大多数病变发生在中老年年龄组。本研究旨在回顾表现出这些罕见人口统计学和放射学标准组合的病变情况。
对年轻患者下颌前部单房性透射区的病例进行回顾性分析。检索过去10年的记录。共有17例患者。从病例档案中查阅他们的临床病史和X光片,并与病变的组织病理学检查结果进行关联。
9种不同病变构成了这17例的样本量。发现一系列病变表现出相似的体征、症状和影像学表现,即成釉细胞瘤(3例)、腺样牙源性肿瘤(AOT,4例)、牙源性角化囊肿(OKC,3例)、骨化性纤维瘤(OF,2例)、特发性骨腔(IBC,1例)、含牙囊肿(DC,1例)、根端囊肿(RC,1例)、中央巨细胞肉芽肿(CGCG,1例)和钙化牙源性囊肿(COC,1例)。
下颌前部是骨内病变发生的罕见部位。大多数患者为女性。病变在被发现之前已长得很大。其生长主要是长度增加而非宽度增加。牙根吸收并不少见,牙根移位几乎是一个一致的特征。
