EndoTooth 37 Lower Molar (More Complex)

• Lower molar (37 ISO notation)
• 3 root canals
• Intact / Accessed
• With or without pulpal tissue
• Transparent or Opaque
• Difficulty: 3/5

Pulp chamber is slightly contracted. Mesial canals have one common canal entrance. In the first third of the mesial root, they form one ribbon-shaped canal before it divides into the typical mesiobuccal and mesiolingual canals. Both of them are curved in the apical third. MB canal curvature is severe. The apical diameter of the MB canal is 0.16 mm and 0.12 mm for the ML canal.

The distal canal is wide and ribbon-shaped. It is formed by the distobuccal and distolingual canals connected with an isthmus, which can be seen on the cross-section. Between the middle and the apical third, the isthmus narrows down until it disappears for a 3 mm distance. The only portal of exit is placed slightly laterally, and the apical diameter of the distal canal is 0.15 mm.
