Common errors
- Failing to locate the middle mesial canal
- Over-cutting the distal wall and perforating
- Ignoring the lingual inclination of the tooth
- Accepting strip-thin mesial walls after shaping
Basic Students — Closed Access
Lower First Molar
4K-BSC-LM
The most commonly treated molar in endodontics — and the most error-prone. Teaches multi-canal access, middle mesial canal detection, and crown-down techniques.
Intermediate
Multi-Canal
L6 Molar
Why this model
Its clinical value.
The lower first molar is the workhorse of endodontic practice — and the most forgiving of good technique, the most punishing of shortcuts.
Clinical context
How this model trains.
Training protocol
- Trapezoidal access with lingual tilt compensation

- Dual-angle radiographic check at MAF
Success criteria
- All canals located (3 or 4)
- Preserved mesial wall thickness ≥ 1 mm
- Dense, void-free obturation of every canal
