A New Anatomically Based Nomenclature for the Roots and Root Canals—Part 2: Mandibular Molars

Figure 3

Diagrammatic representation of various root and canal configurations in mandibular molars named according to the proposed nomenclature. (a) A single canal in each principle root is named as mesial (M) and distal (D). (b) A single-rooted mandibular molar with a centrally located single canal is named as central canal, denoted as “Cn”. (c) Mandibular molar with a C-shaped canal extending from the mesiolingual (ML) to the distobuccal (DB) and a distinct mesiobuccal (MB) canal would be denoted as C-ML-DB, MB. (d), Mandibular molar with a C-shaped, centrally located canal extending from the MB to ML is denoted as C-Cn-MB-ML.
