EndoTooth 14 Upper Premolar

EndoTooth 14 Upper Premolar

• Challenging upper premolar (14 ISO notation) with 3 root canals
• Accessed and intact variant
• With or without pulpal tissue
• Transparent or Opaque
• Difficulty level: 4,5/5

The pulp chamber is slightly contracted, with 2 canal entrances on the floor.

The buccal canal bifurcates after 5 mm into two canals, each with its own portal of exit. This bifurcation replicates the outer buccal root configuration. Because of the bifurcation and significant curvature in the apical third, shaping the buccal root canals presents a challenge.

Buccal root canals have apical diameters of 0.13 mm and 0.12 mm.

The palatal root canal has a slight curve buccally and is 0.11 mm wide at the apex.

The apical thirds of the canals are very narrow, and their negotiation is difficult.
