I am an associate professor at the University of Padua's (Italy) Master's program in Endodontics, and have been a member of the AAE (American Association of Endodontists) since 1990. My own practice (Studio Odontoiatrico Associato) is dedicated exclusively to Endodontics. As a result, I have tried a lot of dental devices and instruments-especially endo ultrasonic tips-but I was never satisfied until I discovered the highly-effective and long-lasting tools manufactured by SD Swiss.It is my pleasure to write a brief synopsis of two tough cases explaining how effective SD Swiss's ultrasonic and endodontic instruments are in a real practice. Hopefully the ordered sequence outlined below will help illustrate these tools' successful use in a complex procedure.CASE 1: Complex RetreatmentStep 1. Removal of the post with the OUTPOST Endodontic Post Removal deviceStep 2. Debriding the pulp chamber with the INDY-300 Diamond Retreatment TipStep 3. Retrieval the silver cones with the IRS® Instrument Removal SystemStep 4. Final clean of the canal walls with the INDY-600 (steps 3 and 4 under microscope)CASE 2:Step 1. Under microscope vision debridement of the cement in pulp chamber with the INDY-400 (thinner to avoid touching the silver cones)Step 2. Retrieval the silver cones with the IRS®Step 3. Final clean of the canal walls with the INDY-600 (low power setting)Dott. Alberto Rieppi graduated in medicine and surgery at the University of Trieste, and received his graduate degree in Endodontics at the University of Verona. He is an adjunct professor in Endodontics at the University of Padua, is an active member of the SIE (Società Italiana di Endodonzia), AIOM (Italian Academy of Microscopic Dentistry) and ESE (European Society of Endodontology).An active speaker, Dott. Rieppi has made presentations at numerous national and international conferences on Endodontics (SIE, Egyptian Association of Endodontics, Warm Gutta-Percha Study Club) and has authored numerous publications (Journal of Endodontics Italian - Italian magazine of Stomatology). His practice is dedicated exclusively to Endodontics.
