Non-Surgical Root Canal Retreatment: Seminar & Hands-On Workshop by Yoshi Terauchi

Non-Surgical Root Canal Retreatment: Seminar & Hands-On Workshop by Yoshi Terauchi is organized by OHI-S and will be held from May 08 - 09, 2027 in New York, United States of America.

Program:
Advanced endodontic techniques with Yoshi Terauchi and a unique opportunity to explore his signature non-surgical root canal retreatment protocols at an intensive seminar!

You will gain a systematic and in-depth understanding of key aspects of retreatment:

– Accurate diagnosis and treatment planning for non-surgical retreatment
– Effective and safe techniques for removing gutta-percha and bacterial biofilms from root canals
– Methods to prevent and bypass ledges in canals using predictable and practical approaches
– Innovative root canal obturation techniques using MTA.

This seminar is not just a transfer of knowledge — it’s an opportunity to transform your clinical approach to the most complex endodontic cases.
