Abstract

Objective: The horizontal tube-shifting technique can be adopted to separate overlapping buccal roots of the maxillary molar from the palatal root. A simulation study was performed to determine an appropriate tube-shift angulation when adopting three-dimensional computed tomography imaging.

Methods: Cone-beam computed tomography images of 21 volunteers were used for simulation. Adopting image analysis software, maximum intensity projection (MIP) three-dimensional images of maxillary molars observed from directions similar to the direction of an intraoral radiography X-ray beam were reconstructed. The orthoradial projection angle was taken as the baseline and the tube-shifting technique was then simulated to separate superimposed buccal roots from the palatal root.

Results and conclusion: The tube-shift technique was considered applicable to maxillary molars for 29/42 teeth (69%) in the case of a mesial tube shift and 40/42 teeth (95.2%) in the case of a distal tube shift. The specific shifting angle suitable for observing the buccal root apex of the maxillary molar without overlapping was obtained.

重新考虑上颌臼齿口内放射摄影中的水平管移动技术。

目的：采用水平移管技术分离上颌磨牙重叠颊根与腭根。在采用三维计算机断层成像时，进行了模拟研究，以确定适当的管移位角度。方法：采用21名志愿者的锥形束ct图像进行模拟。采用图像分析软件，重建与口腔x线摄影方向相似的上颌磨牙最大强度投影（MIP）三维图像。以垂直投影角度为基线，模拟移管技术分离重叠颊根与腭根。结果与结论：上颌磨牙近端移管29/42(69%)，远端移管40/42（95.2%）。获得了适合观察上颌磨牙颊根尖而不重叠的具体移动角度。

期刊介绍： As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
