Abstract

Background: A simple bone cyst (SBC) is a non-neoplastic intraosseous cavity without an epithelial lining. It is usually asymptomatic and has little effect on the surrounding structures. SBC associated with root resorption of the involved tooth has seldom been reported.

Case presentation: A 63-year-old Korean woman was referred to our hospital for a cystic lesion of the left mandibular second molar. Radiographic examination revealed a well-demarcated radiolucent lesion with severe root resorption in the involved tooth. The tooth was extracted, and surgical exploration revealed an empty cavity with only a small amount of fibrous connective tissue. Histological examination revealed external root resorption in the left mandibular second molar and a cystic structure consisting of fibrous collagenous tissue devoid of an epithelial lining.

Conclusions: This case of SBC associated with root resorption offers valuable insight into the diagnostic process for radiolucent lesions accompanied by root resorption.

单纯性骨囊肿伴严重牙根吸收1例。

背景：单纯性骨囊肿（SBC）是一种没有上皮衬里的非肿瘤性骨内腔。它通常是无症状的，对周围的结构几乎没有影响。与牙根吸收有关的SBC很少被报道。病例介绍：一名63岁的韩国妇女被转介到我们医院左下颌第二磨牙囊性病变。x线检查显示在受累的牙齿上有一个界限清晰的放射状病变，伴有严重的牙根吸收。牙齿被拔出，手术探查显示一个空腔，只有少量的纤维结缔组织。组织学检查显示左下颌第二磨牙外根吸收和囊性结构，由纤维性胶原组织组成，缺乏上皮衬里。结论：本例伴有根吸收的SBC为诊断伴有根吸收的放射状病变提供了有价值的见解。
