Your apex locator isn’t giving you a zero reading. Your file is stuck. You’re wondering—have you ledged? Or could something else be at play?

In this must-listen follow-up episode, Dr. Samuel Johnson returns to tackle the biggest endodontic dilemmas left unanswered from part one. If you haven’t checked that out yet, go back and listen—it’s packed with insights on working lengths, apex locators, and even the role of consent in endodontics.

Now, in part two, we go deeper. We’re talking blockages, ledges, portals of exit, and the mysterious phenomenon of file gripping. Plus, Dr. Johnson takes on your burning questions from the Protrusive community—like how he responds to biological dentists claiming root canals should be avoided entirely. (Yep, we’re addressing that controversy head-on!)
