Common errors
- Treating as routine premolar endo
- Using rotary in an irregular chamber
- Under-irrigating the expanded zone
- Inadequate magnification
Immature Open Apex & Resorption
Internal Resorption — L4 Premolar
4K-IRS-L4
Posterior internal resorption in a premolar context — less commonly seen but diagnostically deceptive. Challenges access design and filling in a posterior setting.

Why this model
Its clinical value.
Internal resorption in a lower premolar is rare and easy to misread as pulp stones or secondary caries. The model trains differential diagnosis under posterior constraints.
Clinical context
