Summary

External root resorption (ERR) is irreversible tooth structure loss, often caused by persistent periapical inflammation from infection. This case highlights the importance of diagnosing and treating ERR with intracanal medicaments for microbial debridement.

Area of Science:

  • Dentistry
  • Endodontics
  • Oral Pathology

Background:

  • External root resorption (ERR) involves irreversible loss of external tooth structure.
Keywords:
