A New Anatomically Based Nomenclature for the Roots and Root Canals—Part 1: Maxillary Molars
Figure 1
Diagrammatic representation of the various canal configurations in maxillary molars with names according to the proposed nomenclature. (a) The principle canals in maxillary molars are named in accordance with the traditional approach as mesiobuccal (MB), distobuccal (DB), and palatal (P). (b) An additional palatally located mesiobuccal canal is named as palato-mesiobuccal, P-MB. (c) An additional distally located mesiobuccal canal is named as disto-mesiobuccal, D-MB. (d) Two additional palatally located mesiobuccal canals in the mesiobuccal root are named as palato-mesiobuccal, P-MB, and middle-mesiobuccal, m-MB. (e) Two canals in the palatal root are named as mesiopalatal, MP, and distopalatal, DP. (f) Three palatal canals within the same palatal root are named as mesiopalatal (MP), middle-palatal (m-P), and distopalatal (DP).
