Most endodontically treated teeth fail due to prosthetic issues like crown fractures, not endodontic problems. Restored teeth show better longevity, highlighting the importance of proper prosthodontic rehabilitation after root canal treatment.

Area of Science:

  • Dentistry
  • Endodontics
  • Prosthodontics

Background:

  • Endodontically treated teeth require careful management to ensure long-term success.
  • Understanding failure modes is crucial for improving treatment outcomes and patient prognoses.

Purpose of the Study:

  • To evaluate the primary causes of failure in endodontically treated teeth requiring extraction.
  • To analyze the relationship between prosthetic restoration and tooth longevity.

Main Methods:

  • A retrospective analysis of 116 extracted endodontically treated teeth over a one-year period.
  • Classification of failures into prosthetic, periodontic, and endodontic origins.

Main Results:

  • Prosthetic failures accounted for 59.4%, predominantly due to crown fracture.

  • Periodontal failures represented 32% of cases.
  • Endodontic failures were less common (8.6%) but manifested earlier.

    • Conclusions:

    • Prosthetic complications, particularly crown fractures, are the leading cause of failure in endodontically treated teeth.
    • Crowned teeth demonstrate significantly longer survival rates compared to uncrowned teeth.
    • While less frequent, endodontic failures require prompt identification due to their rapid onset.
