This micro-credential provides an evidence-based clinical update on the primary pillars of endodontic therapy: instrumentation, biological disinfection, and three-dimensional obturation. The curriculum integrates the mechanical principles of NiTi rotary systems with advanced irrigation activation (sonic and ultrasonic) to ensure profound microbial control. Through intensive hands-on training on natural extracted teeth, participants will master both continuous wave compaction and contemporary bioceramic-based techniques to achieve predictable long-term clinical outcomes.
