Michael Solomonov, DMD, is an Israeli board certified endodontist and the director of the Postgraduate Endodontic program in Endodontics at the Sheba Medical Center, Tel-Hashomer, IDF, Israel .
Dr. Solomonov received his DMD degree at the Tel Aviv University in Israel in 1994, and in 2002 graduated from the 3 years postgraduate program in Endodontology at the Hebrew University – Hadassah in Jerusalem.
From 2003 to 2010 Dr. Solomonov served as an Associate Professor at the Hebrew University, Hadassah School of Dental Medicine, Department of Endodontics, Jerusalem. From 2011 he serves as the director of the postgraduate endodontic program in Endodontic department at the Sheba Medical Center, Tel-Hashomer, IDF, Israel.
From 2008 Dr. Solomonov is an examiner for the Israeli Board of Endodontics at the Scientific Council of the Israeli Dental Association.
Contemporary approaches to non round canals in Endodontics
Endodontic instrumentation keeps evolving. While we have been satisfied with our hand files in the past, and we are happy with the flexibility of our nickel-titanium rotary instruments today, we should be aware that the reality of the root canal morphology is much more complex and labyrinthine.
The 3D morphology of the root canals has been thoroughly investigated in the last two decades – in micro-CT studies, histological studies, and CBCT studies. Technologies such as CBCT and clinical microscopes have even brought the ability to better investigate the complex root canal morphology into our daily clinical use, and it is now clear that round canals are not the common case. Our everyday struggle in the endodontic clinic is with oval, long-oval or flattened canals, with C-shaped canals and with canals with isthmuses, recesses and lateral canals.
Although current endodontic instrumentation techniques – rotary and reciprocating - represent a great advancement in cleaning and shaping of root canals, they still have several basic drawbacks. Such drawbacks include the inability to touch most of the root canal walls, and the creation of debris that cannot be removed even with advanced irrigation techniques – either because this debris is packed into untouched areas, isthmuses and fins, or because it is extruded periapically.
This presentation will review the current knowledge-base of irregular non-round root canals, and will inspect the application of new instruments that were introduced in recent years with a goal to overcome these issues, including the XP-Endo Finisher, TruShape, GentleFile and the Self-Adjusting File (SAF) System. Our evidence-based approach will focus on recent scientific literature about these new instruments, as well as on clinical cases.
