"C"-shaped canal configuration of mandibular second permanent molar.

open access: yesCollegium antropologicum, 1998
Roots of the second mandibular molar often fuse so the purpose of this investigation was to examine the appearance of "C"-shaped root canals and to classify different root canal types. A hundred and twelve randomly chosen second lower permanent molars-after extraction due to periodontal disease-were prepared and then analysed.
