摘　　要：目的:探索下颌磨牙融合形牙根的根管系统构筑规律。方法:100例融合根形态的下颌磨牙采用透明法显示根管系统的空间构筑,在体视显微镜下观测并记录其形态图象。结果:融合根外形与其内的主根管分型间并无规律可循,而侧副管以管间吻合常见。结论:主根管可分为"多支型"和"直通型"两类,传统的根管分型在融合根中已不适用。Objiective：Regularity seeking for fusional roots of mandibular molars on pulp cananl system. Method：100 specimen was studied with a lucency way through the pulp cavity,and their pulp cananl was observed and counted according to devise methods. Result：There is two-types pulp cananl（Morobranches and Immediobranches） on mandibular molars fusional root. It is common of anastomosed canals on accessory canals. Conclusion：It is disrelated between outlines of fusional roots and figure of the pulp canal system.
