Figure 4
(a) Radiograph showing the root morphology of five separate roots named using the traditional terminology. MB: mesiobuccal, DB: distobuccal, DP: distopalatal, and MP: mesiopalatal. (b) Access opening picture of the same tooth showing the names of the canals as per the traditional approach, wherein each root has a single canal. (c) Radiograph, as seen in (a), with designation of roots according to their anatomical positions as per the proposed nomenclature. “R” signifies the presence of an additional root. P-MBR: palato-mesiobuccal root, MPR: mesiopalatal root, and DPR: distopalatal root. (d) Picture, as seen in (b), with naming of canals according to the recommended nomenclature.
