Demystifying Molar Endo with Dr. Matt Chesler

Episode Title: Demystifying Molar Endo: Metallurgy, Apex Locators, and Safe Canal Negotiation Host: Dr. Melissa Seibert (Dental Digest Podcast)

Guest: Dr. Matt Chesler, DDS, MS (Board-Trained Endodontist & Resident Faculty at Spear Education)

Episode Summary For many general practitioners, molar endodontics presents high anxiety before ever reaching a canal . Staring into an access preparation, searching for the pulp chamber, and worrying about over-drilling or ledging can cause significant stress . In this episode, Dr. Matt Chesler breaks down these fears by sharing practical, evidence-based approaches to modern instrumentation, glide path creation, working length determination, and retreatment decision-making .

Dr. Chesler discusses why hand files are often the true culprit behind ledges, how modern reciprocating files offer a safer envelope of motion, why apex locators far outperform 2D radiographs, and why coronal sealing and high-quality restorations dictate long-term success .
