Decision making around retreatment cases

Endodontic retreatment: Considerations, case selection, and predictable outcomes

Overview

This video serves as an introduction to endodontic retreatment, covering various reasons for treatment failure, case selection criteria, and clinical approaches to achieve predictable outcomes. Emphasis is placed on clinical case analysis.

Key topics covered

• Key reasons for endodontic treatment failure, including missed anatomy and re-infection
• Differentiating tooth-related and patient-related factors when assessing treatment failure
• Importance of considering limited mouth opening, calcified canals, and anatomical complexities
• The significance of infection pathways like caries, cracks, and marginal breakdown
• Importance of maintaining aseptic technique during retreatment
• Understanding when cone-beam computed tomography (CBCT) is useful for diagnosing and treatment planning
• The need to remove the coronal gutta-percha and restoration to visualise crack extent
• Factors affecting prognosis, such as probing depth, the presence of cracks, and tooth position in the arch

Clinical relevance

The video provides a framework for dentists to approach endodontic retreatment cases with a greater understanding of the challenges and how to select cases with a high likelihood of success. It emphasises careful case assessment, considering factors like the restorability of the tooth, the presence of fractures, and the extent of periapical pathology, allowing for informed decision-making.

Learning outcomes

After watching this video, dentists will be able to:

• Identify key factors contributing to endodontic treatment failure
• Assess case complexity based on factors like anatomical abnormalities, restorative status, and patient-related issues
• Determine when CBCT is necessary for accurate diagnosis and treatment planning
• Development Outcome C - Maintenance and development of knowledge and skill within your field of practice
