牙髓病和根尖周疾病的正确诊断和成功治疗需要影像诊断技术提供有关患牙和周围组织结构的关键信息[1]。因此,影像学检查在牙体牙髓疾病的诊断和治疗中具有十分重要的意义。尽管X线片检查仍是临床上基本的、必需的手段,但由于它是将三维解剖影像压缩成二维呈现出来[2],在诊断时有其局限性和不足。锥形束CT(cone-beam CT,CBCT)的出现为口腔颌面部疾病的诊断和治疗提供了重要的指导作用,是目前应用于牙体牙髓病
Correct diagnosis and successful treatment of endodontic and periapical diseases require diagnostic imaging techniques that provide crucial information about the structure of the affected tooth and the surrounding tissue [1]. Therefore, imaging examination in the diagnosis and treatment of dental pulp disease has a very important significance. Although X-ray examination is still a basic and necessary clinical tool, it is limited and inadequate in diagnosis because it is a three-dimensional anatomical image compressed into two dimensions [2]. The appearance of cone-beam CT (CBCT) provides an important guide for the diagnosis and treatment of oral and maxillofacial diseases. It is currently used in dental pulp disease
