Persistent bacterial infection in endodontic cases, particularly with existing periradicular rarefaction, significantly correlates with treatment failures. Filling extent did not impact success rates in this study.

Area of Science:

  • Dentistry
  • Endodontics
  • Microbiology

Background:

  • Endodontic treatment aims to eliminate intraradicular infection and prevent periradicular disease.
  • Treatment failures can occur despite meticulous procedures, necessitating identification of key etiological factors.

Purpose of the Study:

  • To identify the primary factors contributing to endodontic treatment failures in cases without advanced periodontal disease or structural complications.
  • To investigate the correlation between bacterial presence, periradicular status, and root canal filling extent with treatment outcomes.

Main Methods:

  • Clinical, radiographic, and histobacteriological analysis of 236 endodontic treatment failures.
  • Exclusion of cases with advanced periodontal disease, postperforations, or fractures.

  • Assessment of bacterial infection, periradicular rarefaction, and root canal filling apical extent.

    • Main Results:

    • A significant correlation was observed between bacterial infection within the canal system and the presence of periradicular rarefaction.
    • Persistent bacterial infection in the canal space and/or periradicular tissues, along with preoperative periradicular rarefaction, were identified as major factors for failure.
    • The apical extent of root canal fillings (underfilled, flush-filled, or overfilled) showed no correlation with treatment failures.

    Conclusions:

    • The persistence of bacterial infection is a critical determinant of endodontic treatment failure.
    • Preoperative periradicular rarefaction is a significant indicator associated with endodontic treatment failure.
    • Root canal filling length is not a primary factor influencing the success or failure of endodontic treatment.
