Vertical root fractures (VRFs) pose a clinical dilemma and a challenge to clinicians. Definitive diagnosis is often complicated by the lack of consistent signs and symptoms and the low sensitivity of conventional radiographs in the detection of VRFs. New radiographic imaging systems have recently become available for use in dentistry. Among these new imaging technologies is cone-beam volumetric tomography (CBVT). CBVT technology allows the precise visualization and evaluation of teeth with VRFs. The use of CBVT has great potential as a diagnostic tool to assist in the detection of VRFs.
Seven cases are presented to demonstrate the use of CBVT in detection of VRFs in endodontically treated teeth.
Five specific findings on CBVT exam were consistent with confirmed VRFs.
As demonstrated in this case series, CBVT can provide valuable additional diagnostic information in the detection of VRFs and may help prevent unnecessary treatment.
垂直根折(VRF)给临床医生带来了困境和挑战。由于缺乏一致的症状和体征,以及传统射线照相术在检测 VRF 方面的低灵敏度,明确诊断通常很复杂。最近,一些新的放射影像学系统已可用于牙科。这些新的成像技术之一是锥形束容积断层扫描(CBVT)。CBVT 技术可精确可视化和评估有 VRF 的牙齿。该技术具有作为诊断工具的巨大潜力,可帮助检测 VRF。
介绍了 7 例病例,以展示 CBVT 在检测根管治疗后牙齿 VRF 中的应用。
CBVT 检查中出现了 5 种与确诊 VRF 一致的特定发现。
如本病例系列所示,CBVT 可以在检测 VRF 方面提供有价值的额外诊断信息,并可能有助于避免不必要的治疗。
