Abstract

Endodontic treatment is a predictable procedure with high success rates. Success depends on a number of factors, including appropriate instrumentation, successful irrigation and decontamination of the root canal space up to the apices.

Complete preparation of the canal with proper working length and adequate debridement of infectious tissue are essential factors to successful root canal treatment.

Occasionally,  iatrogenic canal blockages might hinder our ability to achieve patency to the apical third jeopardizing the treatment outcome.

In this lecture we will try to give some indications to avoid some of these complications and explain how we can deal with them when they happen.

Learning Objectives

• Understand the problem of different iatrogenic blockages (canal blockage, ledges, separated instruments)
• Understand how to manage a canal blockage
• Understand how to bypass and eliminate a ledge
• Understand how to bypass a separated instrument 
• Take away tips and tricks to use in everyday practice
