Endodontic procedural errors like underfilling or perforations do not directly cause treatment failure. However, they increase failure risk by allowing pathogens, which are the true cause of periradicular pathosis.

Area of Science:

  • Dentistry
  • Endodontics

Background:

  • Reviews the impact of common endodontic procedural errors on treatment outcomes.
  • Errors include underfilling, overfilling, root perforations, and separated instruments.

Purpose of the Study:

  • To analyze how endodontic procedural errors affect treatment success.
  • To identify the relationship between procedural errors and treatment failure.

Main Methods:

  • Literature review of endodontic procedural errors and their consequences.
  • Analysis of factors contributing to procedural errors.

Main Results:

  • Procedural errors do not directly cause failure; pathogens in untreated canals are the primary cause of periradicular pathosis.
  • Errors stem from a lack of understanding of root canal anatomy, instrumentation, and healing principles.

Conclusions:

  • Procedural errors impede endodontic therapy and elevate failure risk, particularly in teeth with necrotic pulps and lesions.
  • Most procedural errors are preventable with proper technique and understanding.
