Dr. Terauchi is a part-time Professor at Tokyo Medical & Dental University and maintains a private practice limited to endodontics since 1998 in Tokyo, Japan. He earned his DDS in 1993 and completed his residency at Tokyo Medical & Dental University in 1995, where he also received his PhD from the Department of Endodontics. He has published numerous articles in peer- reviewed journals nationally and internationally. He also authored in several chapters in textbooks including the 11th edition of Pathways of the Pulp.

Dr. Terauchi is a founder of the biggest dental training center in Japan limited to endodontics called Dental Arts Academy.

The main scientific focus of Dr. Terauchi has been Broken File Removal, bypassing the ledges and MTA-obturation in the field of endodontics. He is an inventor of numerous methods and technics in broken file removal, including specific devices and instruments such as the famous TFRK (Terauchi File Retrieval Kit), 812 MT endomotor and many others.

Instrument retrieval may be unpredictable unless a standardized protocol is followed. Removal of visible broken instruments may be 100% predictable following precise guidelines. In addition, longer separated instruments present more difficulties and require different techniques. Any technique should aim at preserving as much tooth structure as possible to prevent root fracture and perforation. In this hands-on course, unique techniques for instrument retrieval will be presented to make the retrieval highly predictable and minimize dentin sacrifice. Participants will learn how to make an accurate evaluation of each case with instrument separation, establish a precise treatment plan, and adopt the most adequate techniques to successfully remove the separated instrument with the minimum sacrifice of sound tooth structure.

This will be a LIVE-streamed, hands-on demonstration by Dr. Yoshi Terauchi, broadcasting from Oslo, Norway, on February 14th, 2026.
A dental microscope will be installed on stage, allowing Dr. Terauchi to perform a real-time clinical demonstration throughout the meeting. Participants will be able to observe every detail of the procedures as they happen.
Among many advanced techniques and clinical procedures, Dr. Terauchi will demonstrate his latest tools and instruments for broken file removal, shown live and in action under high magnification.

Dr. Domenico Ricucci received his degree in General Medicine from "La Sapienza" University of Rome in 1982, and his DDS from the same University in 1985. Since then on he has maintained private dental practices limited to endodontics. In addition to his private practice, Dr. Ricucci was Professor of Cariology at "Magna Graecia" University of Catanzaro, Italy in 2002 -2003. He served in the Research Committee of the European Society of Endodontology from 1999 to 2005. Dr. Ricucci's primary research interest relates to pulpal and periapical tissue reactions to caries and treatment procedures, vital pulp therapy (VPT), biofilms in endodontic infections, etiology of RTC treatment failure, pulp regeneration/revascularization. Since 1998 he has run his own histology laboratory and has developed considerable skills in hard tissue preparations for light microscopy. Dr Ricucci has published more than 100 papers and has lectured both nationally and internationally. He has authored the Textbook and Atlas "Endodontology". An integrated biological and clinical view". He has also a founder and a scientific director of the international endodontic project Endo Sapiens.
