Abstract：
This case presents clinical techniques and materials that may be applied in the management of internal tunnelling root resorption, a rare condition which has little published literature.A 25-year-old woman was referred to a specialist centre by her general dental practitioner following an incidental finding of a radiographic radiolucency, suggestive of root resorption associated with tooth 21. A provisional diagnosis of external cervical resorption was made, and following cone beam computed tomography (CBCT), a definitive diagnosis of internal tunnelling root resorption given. Non-surgical endodontic treatment was completed using continuous wave compaction with a calcium-silicate based sealer. No further intervention has been required.A summary of the histology, aetiology, prevalence, diagnosis, management and prognosis of internal tunnelling root resorption is provided. The benefits of CBCT for diagnosing and managing internal tunnelling resorption defects and using continuous wave compaction with a calcium-silicate based sealer, compared to cold obturation techniques, are discussed.
摘要：
此案例介绍了可用于内部隧道牙根吸收管理的临床技术和材料，一种很少有文献发表的罕见疾病。一名25岁的妇女在偶然发现射线照相射线可透性后，由其普通牙医转介到专科中心，提示牙根吸收与牙齿有关21。暂时诊断为宫颈外部吸收，以及随后的锥形束计算机断层扫描(CBCT)，给出了内部隧道根吸收的明确诊断。使用基于硅酸钙的密封剂的连续波压实完成非手术牙髓治疗。不需要进一步干预。组织学总结，病因学，患病率,诊断,提供了内部隧道牙根吸收的管理和预后。CBCT用于诊断和管理内部隧道吸收缺陷以及使用硅酸钙基密封剂的连续波压实的好处，与冷闭塞技术相比，正在讨论。
