Le Big Live: Part 1

Overview

In the first part of our "Big Live" evening we are joined by guest speaker Professor Frederic Bukiet, who provides a comprehensive overview of bioceramic sealers and the concept of hydraulic condensation. He explores the chemistry, properties, and clinical application of these materials, addressing the significant disconnect between in-vitro research and real-world practice. The discussion aims to clarify the benefits and potential pitfalls of using bioceramics, particularly with single-cone obturation techniques.

Key Topics Covered

• An introduction to the chemistry of bioceramic sealers (calcium silicate-based), their hydration reactions, and how this process influences their biological properties
• A critical look at the "bioceramic" marketing term and the wide variety of formulations available, emphasising the need to use reputable, well-researched materials
• Discussion of the key properties of bioceramics: dimensional stability, injectability, bioactivity, and antibacterial effects
• The controversial aspects of bioceramics, including their solubility and water absorption, and how these factors impact long-term sealing ability
• Practical clinical considerations, including irrigation protocols (avoiding EDTA as a final rinse), root canal drying, and the challenges of using these materials in conservative access cavities
• A detailed look at the single-cone obturation technique, including sealer placement, master cone fitting, and the use of accessory cones in wider canals to improve hydraulic forces

Clinical Relevance

This presentation is highly relevant as it tackles a popular but often misunderstood topic in modern endodontics. We gain a much clearer, evidence-based perspective on how to properly use bioceramic sealers, helping us to move beyond marketing hype and apply these materials in a way that is predictable, scientifically sound, and beneficial for our patients.

Learning Outcomes

After watching this, dentists should be better able to:

• Understand the fundamental chemistry and key properties of calcium silicate-based bioceramic sealers
• Make more informed decisions when selecting a bioceramic sealer based on available evidence and formulation
• Apply the correct clinical protocols for irrigation, drying, and placement when using bioceramic sealers with a single-cone techniqueCritically evaluate the benefits and limitations of hydraulic condensation and adapt the technique for different canal anatomies
