    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

    Description: An intact coronal seal is important for maintaining the integrity of a root canal filling and preventing reinfection. Coronal leakage provides a source of viable microorganisms and nutrients that initiate and sustain periradicular inflammation. Despite research supporting the effectiveness of coronal barriers, a universally accepted protocol that incorporates a coronal barrier after root canal treatment is non-existent. Different materials have been advocated for use as canal orifice barriers, including temporary or intermediate filling materials, zinc oxide-eugenol cements, amalgam, glass-ionomer cements, resin composites, flowable resin liners and tricalcium silicate cements. While each of these materials has its own benefits and limitations, the appropriateness of using resin-based materials as long-term canal orifice barriers will be examined in this presentation by correlating their barrier properties with their physicochemical and antibacterial characteristics, as well as the durability of the bonds created in dentin to retain these materials.

    • State the rationale for placement of a coronal seal immediately after root canal treatment.
    • Identify the merits and limitations of using resin-based materials as canal orifice barriers.
    • Perform a reasonably durable coronal seal using an antibacterial self-etch adhesive and a radiopaque resin composite.

    Description: The advent of MTA about 2 decades ago brought about a significant change in the practice of clinical endodontics. A material that suited our work-space and the periradicular tissue, perfectly. It has been extensively investigated in in-vitro, animal and clinical studies. With due diligence in the literature, material has our academic and investigative endorsement. However, there are limitations to use of MTA e.g., inability to use for routine obturation, it’s difficult handling properties and tendency to cause discoloration. Material scientists have worked on overcoming the limitations of MTA by introducing newer generation of Bioceramics. The lecture is an overview of the current research and clinical applications of the newer bioceramics available to us. Published research will be critically reviewed and clinical cases presented demonstrating the applications in various treatment modalitiesson 

    At the conclusion of this course, participants will learn: 

    • Discuss an evidence-based evaluation of the chemical, physical and biological properties of Bioceramics pertinent to endodontics.
    • Explain the clinical use especially as a sealer
    • Recognize the strength and weakness of the material
