A mandibular first molar with two distal roots is an interesting example of anatomic variation. This paper describes case reports of mandibular first molar with three roots (one mesial and two distal) and four canals (two in mesial and one in each distobuccal and distolingual root). The canals were shaped with protaper rotary files and irrigated with 5.25% sodium hyochlorite, 0.2 %w/v of chlorhexidine gluconate and normal saline as the fi nal irrigant. The canals were then obturated with gutta- percha and AH plus sealer. These case reports show an anatomic variation of internal morphology of the tooth and points out the importance of searching for additional canals.
一颗具有两个远中根的下颌第一磨牙是解剖变异的一个有趣例子。本文描述了具有三根（一根近中根和两根远中根）和四个根管（两根在近中根，远颊根和远舌根各一根）的下颌第一磨牙的病例报告。根管使用Protaper旋转锉进行塑形，并用5.25%次氯酸钠、0.2%w/v葡萄糖酸氯己定和生理盐水作为最终冲洗液进行冲洗。然后用牙胶尖和AH plus封闭剂对根管进行充填。这些病例报告显示了牙齿内部形态的解剖变异，并指出了寻找额外根管的重要性。
