这篇研究的目的是通过锥束CT(CBCT)评估下颌磨牙的解剖形态以便根尖外科手术的顺利实施。

研究纳入170例CBCT扫描结果以分析下颌磨牙解剖形态的变异。所有扫描均使用Planmeca Promax CBCT unit (Planmeca, Helsinki, Finland),曝光设置为90 kVp, 12 mA, 12 seconds和0.3-mm的分辨率。所有CBCT影像均通过Romexis Viewer 3.8.2.软件(Planmeca)在一个16-inch LCD显示器(22MP47HQ; LG, Seoul, South Korea)上进行重组,并评估它们轴向、冠状和矢状面的影像。

结果显示,在所有磨牙中,第二磨牙远中根的颊侧骨板最厚,为12.30 mm;在所有前磨牙中,第二前磨牙牙根的颊侧骨板最厚,为5.41 mm。第一和第二前磨牙牙根颊侧骨板最薄处为0.42 mm,而第一磨牙近中根颊侧骨板最薄处为0.62 mm。左侧第二磨牙远中根颊侧切除术的手术入路需要去除20.38-mm厚的断面,根尖距下颌管最短的距离为2者相重合。

结论:充分了解牙齿的三维解剖形态以及围绕它们周围的结构对于实施牙髓外科手术是必要的。另外,对于下颌磨牙牙根切除部位(根尖3 mm)的厚度、颊侧骨板的厚度以及每个牙齿根尖至下颌管和颏孔的距离等相关信息的收集可以在外科手术前和过程中指导外科医师的手术设计和操作。
