Program
Day 1 (July 30)
Theory
Course aim: to enhance participants' knowledge and clinical decision-making skills in non-surgical root canal retreatment and provide a structured approach to the predictable and minimally invasive management of challenging endodontic retreatment cases.
Learning objectives:
— Apply a systematic approach to the diagnosis and treatment planning of non-surgical retreatment cases
— Identify the biological and clinical factors contributing to persistent endodontic disease and treatment failure
— Evaluate and select appropriate techniques for the removal of gutta-percha and biofilms during retreatment
— Apply predictable techniques for the prevention and management of ledged canals
— Assess separated instrument cases and select appropriate strategies for safe and minimally invasive instrument removal
— Recognise the indications, clinical properties and limitations of MTA in retreatment and perforation repair
— Apply evidence-based principles to the management of challenging endodontic retreatment cases.
