Details
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.
Course Outline
