This work studies the morphology of distal roots of the first mandibular with the support of X rays and transversal sections. The frequency of the different types of roots (according to the Weine classification) and the shape of their section is studied statistically. The results enable a better approach of the endodontic shaping.
本研究借助X射线和横断面,对下颌第一磨牙远中根的形态进行了研究。对不同类型牙根(根据魏内分类法)的出现频率及其横断面形状进行了统计学研究。研究结果有助于更好地进行根管预备。
