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.

Expert Internal Resorption Posterior
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

How this model trains.

Common errors

  • Treating as routine premolar endo
  • Using rotary in an irregular chamber
  • Under-irrigating the expanded zone
  • Inadequate magnification

Training protocol

  1. CBCT for 3D mapping
  2. Modified access to expose the defect
  3. Ultrasonic irrigation activation
  4. Thermoplasticized obturation with bioceramic sealer
  5. Long-term radiographic follow-up

Success criteria

  • Defect fully obturated
  • Periradicular healing
  • Tooth asymptomatic long-term
Learning outcomes

What the trainee learns.

  • Posterior resorption diagnosis workflow
  • Access modification for expanded canal
  • Thermoplasticized obturation technique
