EndoTooth 37 Lower Molar (More Complex)
Pulp chamber is slightly contracted. Mesial canals have one common canal entrance. In the first third of mesial root they form one ribbon shaped canal before it divides into typical mesiobucal and mesiolingual canal. Both of them are curved in the apical third. MB canal curvature is severe. Apical diameter of MB canal is 0,16 and 0,12 mm of ML canal.
Distal canal is wide and ribbon shaped. It is formed by distobucal and distolingual canal connected with isthmus what can be seen on the cross-section. Between the middle and the apical third the isthmus narrows down until it disappears for 3 mm distance. The only portal of exit is placed slightly laterally and the apical diameter of the distal canal is 0,15mm.
