Why this case matters
Upper premolars look simple on a radiograph but hide a second canal more often than not. Training here prevents a career-long habit of declaring "one canal" too quickly.
Training outcomes
- Bifurcation detection technique
- Oval access cavity preparation
- Multi-canal obturation strategy
Common mistakes this model helps you avoid
- Circular access cavity missing the buccal horn
- Stopping at one canal without exploring the floor
- Over-instrumenting a thin furcal wall
- Using ISO tip sizes that under-shape oval canals
Suggested training protocol
- Oval access extending bucco-palatally
- Troughing the floor for a second orifice
- Size #10 scouting each canal to patency
- Apex locator confirmation on both canals
- Simultaneous shaping in small increments
What a successful exercise looks like
- Both canals located and patent
- Even taper; no strip perforation
- Dual cone seal with homogeneous sealer
