根管治疗是目前国内、外公认的牙髓及根尖周病最有效、彻底的治疗方法。提高根管治疗术的质量是提高患牙保存率的重要保证。影像检查是惟一能够记存的、贯穿根管治疗术始终的、直观的影像学资料。长期以来,临床常规使用的是根尖片。由于二维影像显示三维立体牙齿的局限,存在重叠、变形、失真等不准确现象。锥形束CT以其低剂量照射、高分辨率、价格低廉、操作简单等诸多优势,被广泛应用于口腔临床的各个相关学科,并成为研究热点。本文主要探讨锥形束CT在根管治疗诊疗计划中的临床应用,与根尖片比较了解其优势。
Root canal therapy is the most effective and thorough treatment of dental pulp and periapical periodontology recognized at home and abroad. Improving the quality of root canal therapy is an important guarantee to improve the preservation rate of teeth. Image examination is the only one that can be recorded, always through endodontic treatment, visual imaging data. For a long time, clinical routine use of root tip film. Due to the limitations of three-dimensional teeth displayed by two-dimensional images, there are inaccuracies such as overlap, deformation and distortion. Cone beam CT is widely used in various related disciplines of oral clinic due to its advantages of low dose irradiation, high resolution, low cost, simple operation and so on, and has become a research hotspot. This article mainly discusses the clinical application of cone beam CT in the diagnosis and treatment of root canal therapy and compares its advantages with the tip film.
