EndoTooth 16 Upper Molar (More Complex)

EndoTooth 16 Upper Molar (More Complex)

• More challenging upper molar (16 ISO notation) with 4 root canals
• Accessed and intact variant
• With or without pulpal tissue
• Transparent or opaque
• Difficulty: 3,5/5

The pulp chamber and root canal system are without significant calcifications or obliterations, except for the MB2 and the narrow canal entrances to the mesiobuccal canals. The MB2 root canal presents a challenge - after a 4 mm long common course with MB1, it separates and continues as a narrow, slightly S-curved canal. Two millimeters prior to the terminus, there is a communication through an isthmus between the two mesiobuccal canals. The apical diameters of MB1 and MB2 are 0.10 mm.

The distal root canal forms a bifurcation in the apical third and reaches an apical diameter of 0.18 mm.

The palatal canal curves slightly buccally in its course, is quite wide, and narrows to 0.10 mm at the apical diameter.
