Endo Voices

In this episode of Endo Voices, Dr. Marcus D. Johnson is joined by internationally recognized endodontists Drs. William Ha and Omar Ikram for a wide-ranging conversation on where endodontics is headed—and how education, technology and clinical experience are shaping the specialty worldwide. From the impact of CBCT, microscopes and reciprocating instrumentation to the evolving role of artificial intelligence, they explore how emerging innovations are improving efficiency, expanding case selection and helping clinicians preserve more teeth while maintaining predictable outcomes.
The discussion also dives into modern endodontic education, managing calcified canals and retreatment cases, and the importance of balancing technological advances with evidence-based decision making and sound clinical judgment. Along the way, the trio shares practical pearls for clinicians at every stage of their careers, addressing the future of the specialty and the upcoming IFEA World Endodontic Conference in Sydney—highlighting why collaboration, lifelong learning and thoughtful innovation remain essential to advancing patient care.

Separated instrument retrieval remains one of endodontics’ most technically demanding—and humbling—procedures. In this episode of Endo Voices, Dr. Marcus Johnson joins internationally recognized clinician, researcher, and educator Dr. Yoshi Terauchi for a highly technical yet practical exploration of the science and strategy behind predictable instrument retrieval. From cyclic and torsional fatigue to canal curvature, fragment location, and CBCT assessment, Dr. Terauchi explains why successful retrieval begins with diagnosis, visualization, and disciplined treatment planning.

Dr. Terauchi shares the principles behind his systematic approach to retrieval, including strategic dentin removal, ultrasonic technique, bypassing, and the clinical application of the Yoshi Loop. The conversation highlights the delicate balance between persistence and preservation: when does continued retrieval become more damaging than the fragment itself? Along the way, Drs. Johnson and Terauchi discuss secondary fracture, apical displacement, pericervical dentin preservation, tactile sensation, and those difficult cases in which the separated instrument lies beyond the curvature.

At AAE26 in Salt Lake City, Dr. Marcus Johnson sits down with former AAE President Dr. Terryl Propper for a candid conversation on leadership, mentorship, and the evolution of endodontics. From becoming the first female president of the Tennessee Dental Association to co-founding Endodontic Practice Partners, Dr. Propper reflects on the experiences that shaped her career and the lessons learned through decades of service, advocacy, and innovation.

Together, they explore the importance of identifying and developing future leaders, building meaningful patient relationships, adapting to change in a shifting practice landscape, and creating a culture rooted in trust, accountability, and empowerment. With insight, humor, and authenticity, Dr. Propper shares why leadership begins long before the boardroom—and why the future of endodontics depends on those willing to step forward and make a difference.

In this episode of Endo Voices, Dr. Marcus Johnson sits down with outgoing AAE President Dr. Steven Katz for an honest and reflective conversation about leadership, mentorship, and the future of endodontics. From his early days on the Public and Professional Relations Committee to leading one of the most visible years in AAE history, Dr. Katz shares the experiences that shaped his presidency, including the organization’s expansive media outreach, the evolution of the Worth Saving campaign, and the development of the updated CBCT position statement and trauma guidelines.
Together, they explore the importance of servant leadership, the role of mentorship in organized dentistry, and how endodontists can continue to make meaningful contributions to the specialty at every stage of their careers. Dr. Katz also offers thoughtful insight into the challenges facing the profession—from educator shortages and student debt to the growing influence of AI—while emphasizing the enduring value of humanity, connection, and giving back.

In this episode, we sit down with Dr. Mustafa Gündoğar, researcher, educator, and globally recognized voice in endodontics, to explore the evolving science behind how we truly clean root canal systems. From his journey into endodontics driven by microbiology and patient care, to his extensive research on irrigation activation systems, Dr. Gündoğar challenges long-held assumptions and reframes the conversation: are we shaping to clean, or cleaning to shape? Together, we unpack the critical role of biofilm, the limitations of instrumentation, and why irrigation remains the cornerstone of predictable outcomes.
The discussion dives into advanced technologies like lasers and multisonic irrigation, examining their real-world impact, limitations in clinical data, and the practical considerations of adoption across global practices. Dr. Gündoğar offers a candid perspective on what truly drives innovation, including effectiveness, workflow integration, and economic feasibility, while emphasizing the need for stronger long-term clinical evidence.
