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.

In this episode of Endo Voices, Dr. Marcus D. Johnson sits down with Dr. Pierre Wohlgemuth for a thoughtful and collegial examination of two defining challenges in contemporary endodontics: the elusive cemental tear and the disciplined art of soft tissue management in surgical care.

Cemental tears—seldom discussed yet likely underdiagnosed—often masquerade as endodontic or periodontal pathology. With a limited but growing body of evidence, accurate identification demands clinical vigilance. Key red flags include vital teeth presenting with periapical radiolucencies and persistent disease following technically adequate root canal therapy. The discussion explores the roles of occlusal trauma, CBCT interpretation, and histologic confirmation, reinforcing the importance of expanding the differential diagnosis before defaulting to retreatment or extraction. Decisions surrounding tooth preservation versus implant placement are framed not as reflexive, but as biologically and prognostically driven.

A central theme resonates throughout: clinicians do not rise to the level of their intentions—they fall to the level of their training.
