Pulp chamber and root canal obliteration (PCO/RCO) presents a challenge for clinicians when nonsurgical endodontic treatment is indicated. Guided endodontics (GE) aims to precisely locate the root canal (RC) system while preserving as much pericervical dentin as possible. GE involves integrating cone-beam computed tomography (CBCT) of the affected tooth with a digital impression of the maxillary/mandibular arch, allowing for careful planning of the drilling path to the RC system through a three-dimensional (3D) static guide. This article reports four cases of teeth with PCO/RCO, accompanied by additional diagnoses of internal and external root resorption and horizontal tooth fracture, all successfully treated with GE. These cases highlight the clinical and radiographic success of GE treatments using CBCT, establishing this technique as a predictable approach for managing mineralized teeth.
当需要进行非手术牙髓治疗时，髓腔和根管闭锁（PCO/RCO）给临床医生带来了挑战。引导式牙髓治疗（GE）旨在精确确定根管（RC）系统的位置，同时尽可能保留更多的颈周牙本质。GE包括将患牙的锥形束计算机断层扫描（CBCT）与上颌/下颌牙弓的数字印模相结合，以便通过三维（3D）静态导板仔细规划通往RC系统的钻孔路径。本文报告了4例患有PCO/RCO的牙齿病例，伴有额外的内外部牙根吸收和水平牙折诊断，所有病例均通过GE成功治疗。这些病例突出了使用CBCT进行GE治疗的临床和影像学成功，确立了该技术作为处理矿化牙齿的可预测方法。
