Summary

This case report details a rare dental error: root canal overfilling with iodoform paste. The paste extended beyond the target tooth, spreading through mandibular bone and later resorbing.

Area of Science:

  • Dentistry
  • Endodontics
  • Oral Surgery

Background:

  • Root canal overfilling is a significant procedural error in endodontic therapy.
  • Iodoform paste is a commonly used root canal filling material, known for its radiopacity and potential for resorption.

Observation:

  • A case of significant root canal overfilling involving the left mandibular second premolar is presented.
  • The iodoform paste extended beyond the apical lesion of the treated tooth, reaching the adjacent second molar's apical region.
  • Radiographic imaging revealed the overfilling material extending to the mandibular angulus region, traversing the trabecular bone but sparing the mandibular canal.

Findings:

  • The extensive overfilling demonstrated the potential for root canal filling materials to spread beyond the intended anatomical confines.
  • The eventual disappearance of the radiopaque material suggests the resorptive properties of iodoform paste in vivo.
  • Histological examination of the resorbed material was not performed, but its characteristics support iodoform paste identification.

Implications:

  • This case highlights the importance of meticulous technique in root canal filling to prevent complications.
  • Understanding the behavior and resorption of materials like iodoform paste is crucial for managing overfilling incidents.
  • Further research into the long-term effects and management strategies for extensive root canal overfilling is warranted.
