74(64%) teeth were w ith one root, 41(36%) with two roots, all teeth with two roots had two canals a nd each canal with one apical foramen,〔TypeⅠ(1)〕.39% of the single-root teet h demonstrated one canal, whereas 61% of the single-root teeth had two canals, 〔TypeⅡ(2-1), TypeⅣ(2) and TypeⅤ(1-2)〕.Conclusions:
