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: To prevent and eliminate apical periodontitis, adequate obturation is paramount for successful non-surgical endodontic treatment. Gutta percha and sealer are two needed components, and bioceramic obturation is the newest application to address this. The worldwide use of calcium silicate-based sealers continues to increase along with new obturation techniques. The single cone technique (hydraulic condensation) has become a time-saving, efficient obturation method using bioceramic sealers. But does this technique predictably provide a bacterial tight seal? How does its application affect the performance of these materials? What influence does the single cone technique have on case outcome? This presentation will explore the predictability of the single cone technique, allowing the listener to make an informed decision on whether, and in what situations, to employ it.
Learning Objectives:
- Describe the properties of bioceramic sealer that make the single cone technique possible.
- Discuss how the application of bioceramic sealer affects its performance.
- List the strengths and limitations of bioceramic obturation using the single cone technique.

Description: The obturation of the root canal system is a critical step of the non surgical root canal treatment in order to achieve a positive outcome of the therapy: as a matter of fact an high percentage of endodontic failures are associated with incomplete root canal obturation and apical periodontitis presence. The possibility to get a fluid-tight seal is crucial to prevent percolation of bacteria and it depends on the properties of the sealer and on the obturation technique. Hydraulic Calcium silicate-based sealers properties are driving a paradigm change in obturation towards a more sealer-centric philosophy. The purpose of this presentation is to evaluate the outcome at 2 years of non surgical canal treatments done in a private practice between 2017 and 2021 in teeth with apical periodontitis. All cases, including initial and retreatment, were obturated with bioceramic sealer and CHCT independently of the endodontic anatomy. Outcome was evaluated based on clinical and radiographic findings at recall, with a minimum 2-years follow-up for 525 teeth. Teeth were classified as healed or healing (success), or not healed (failure). Patient and treatment factors were analyzed to determine their significance as prognostic factors. Among the factors even apical size bigger than 50, sealer extrusion and presence of small perforations. The results obtained support the conclusion that the use of bioceramic sealers with the CHCT is a valide option for obturation in text with apical periodontitis.
Learning Objectives:
- Evaluate and perform the clinical techniques for using bioceramic sealers in root canal obturation according with the endodontic anatomy.
- Evaluate the benefits and limitations of bioceramic sealers.
- Implement obturation strategies to get a positive outcome for non surgical canal treatment and retreatment in teeth with clinical and/or radiographic signs of apical periodontitis.

Description: Root canal obturation is a critical step in non-surgical root canal treatment. In recent years, more emphasis is being placed on preserving more natural tooth structure during endodontic treatment in order to improve the long-term survival of the natural dentition. With the introduction of calcium silicate-based root canal sealers, root canal obturation techniques have evolved to adapt to this more conservative philosophy. This lecture will present an overview of the changing philosophy in root canal obturation, discuss the properties of new obturation materials, review the most current and clinically relevant evidence on various obturation materials and techniques, and describe the clinical procedure of the contemporary sealer-based obturation using calcium silicate-based sealers. The lecture will provide evidence-based clinical guidance for endodontists to meet today’s challenges in root canal obturation and achieve a more predictable treatment outcome.
Learning Objectives:
- Explain the objectives and principles of root canal obturation
- Explain the properties of calcium silicate-based root canal sealers
- Explain the rationale and the clinical techniques of sealer-based root canal obturation

Description: Our specialty of Endodontics has evolved, and continues to evolve, through the application of emerging technologies. Advancements in irrigation protocols have allowed for predictable cleaning of the primary canals with more conservative preparations to include no instrumentation. Subsequently, obturation materials and methods have to be modified to accommodate these smaller shapes. This case-based presentation will review the advantages and techniques used to overcome the challenges of such a paradigm shift.
Minimally prepared canal systems with enhanced irrigation have the potential to provide desirable results and conserve tooth structure. Various cases with continued care healing re-evaluations to include CBCT imaging for both pre-operative and recall examination will be presented.
Learning Objectives:
- Compare and contrast traditional tapered canal preparation versus methods and materials used for minimally prepared canals and modified obturation techniques.
- Critically evaluate the advantages of minimal preparation combined with enhanced irrigation and bioceramic sealer as an alternate option for nonsurgical RCT.
- Explain the role of minimally prepared canals and their correlation to the longevity of endodontically treated teeth based on pre-operative and post-operative CBCT comparison.

Description: Root canal sealers are a critical component in obturation to provide a fluid-tight seal of the root canal system. Calcium silicate-based bioceramic sealers have emerged as a promising alternative to traditional resin-based or ZOE-based sealers. The increasing popularity of these materials is driving a paradigm change in obturation towards a more sealer-centric philosophy. The excellent flow characteristics, sealing ability, dimensional stability, and biocompatibility of bioceramic sealers allow them to be used in a simplified obturation technique without compromising the quality of obturation. Since the first bioceramic sealers were introduced in 2008, there has been growing evidence supporting the use of these materials. New products also continue to be developed and introduced. This presentation will provide an update on the recent development in the field of bioceramic sealers, review their relevant properties, discuss the clinical techniques of their application, and present the most current research related to the properties and clinical effectiveness of bioceramic sealers.
Learning Objectives:
- Describe the physical, chemical, and biological properties of bioceramic sealers and understand the benefits and limitations of these materials
- Describe the clinical techniques for using bioceramic sealers in root canal obturation
- Discuss current evidence from in vitro and clinical studies regarding bioceramic sealers
