Why this case matters
The lower first molar is the workhorse of endodontic practice — and the most forgiving of good technique, the most punishing of shortcuts.
Training outcomes
- Middle mesial canal detection
- Crown-down shaping technique

Common mistakes this model helps you avoid
- Failing to locate the middle mesial canal
- Over-cutting the distal wall and perforating

- Accepting strip-thin mesial walls after shaping
Suggested training protocol
- Trapezoidal access with lingual tilt compensation
- Troughing the mesial isthmus for middle mesial
