Description: 

Since the launch of calcium silicate-based bioceramic sealers, the popularity of its clinical applications has grown dramatically in the last 16 years. Almost 50% of the AAE members and 27% of the ADA members reported using this type of sealer, which have surpassed resin-based sealers and it has become the most widely-used sealer type among endodontists. 

Due to the increase of the interest of these sealers, several companies have developed its own version of a calcium silicate-based bioceramics products (sealer and putty). The majority of these products are pre-mixed which simplify the clinical use. While the verity of these products in the market increase considerably in the last 5 years, the number of clinical and laboratory studies on the latest products have been limited. Although many of them are called bioceramic sealers, there are many variation, among them, their chemical components, sealability, biological activities and more.  

In this presentation we will compare the most popular pre-mixed bioceramic products in the market and show their clinical applications and obturation techniques.

Learning Objectives:  

• Describe the endodontic hydraulic bioceramic cements and their clinical interactions 
• Update and compare the traditional and new bioceramics materials available on the market
• Demonstrate tips and tricks on how to use these materials in different clinical cases

Description: A growing number of practitioners use calcium silicate-based sealers in root canal therapy. If the primary treatment has failed, non-surgical retreatment is considered the primary treatment option. However, the retreatability of cases incorporating a calcium silicate-based sealer is debatable as a specific, clinically acceptable solvent has yet to be developed. There are also few outcome studies concerning retreating these cases. This presentation will critically review the current studies addressing retreatment and retreatability of cases incorporating a calcium silicate-based sealer, and discuss methods to retrieve calcium silicate based-sealers combined with gutta-percha cones using different solutions, solvents, primary rotary files, retreatment designed files, heat-treated or non-heat-treated files, ultrasonic or sonic irrigation, in both straight or curved canals exhibiting short, flush with the apex, or overextended obturation.

Learning Objectives:  

• Compare the efficacies of different solvents/irrigants and ultrasonic/sonic irrigation for retreatment cases incorporating a calcium silicate-based sealer
• Evaluate the efficacies of different rotary files for retreatment cases incorporating a calcium-silicate sealer
• Design specific retreatment strategies for clinical scenarios involving straight or curved canals, and patent or non-patent canal cases

Course Description: 

A short introduction to "level of evidence in endodontic research" will be given. The lecture will continue with a description of the building blocks for success in endodontic treatment, and how these have changed (or not!) during the decades. We will then look at the “endodontic triad” as a disease/treatment model and how the three arms are related. An identification of how legacy protocols came out of the then available technology will be discussed with an emphasis on the continued evolution of debridement technology and how it has impacted the other arms of the triad and challenges our ideas around obturation. The use of new sealers that effectively seal in large film thicknesses, the concept of gutta percha points used as a condenser rather than an obturation material, and a review of the need for vertical condensation will also be evaluated along with whether obturation will really be necessary in the future.

At the conclusion, participants should be able to:

• Describe the inter-relation of the classic endodontic triad arms and how changing one will influences the others.
• Discuss what near-term treatment protocol changes are possible and how they may simplify endodontic treatment.
• Evaluate whether or not the protocol changes that are possible today are more effective.
