Mechanical Root Canal Preparation: Is Less Really More?
Roggendorf, M. J. / Roggendorf, H. C. / Ebert, J. / Braun, A. / Frankenberger, R.
Instrumentation of the root canal received a fundamental new impetus in the 1990s with the introduction of nickel-titanium (NiTi). Tedious and time-consuming manual preparation was revolutionised by mechanical instrument systems and has experienced more and more innovations in the last two decades. While the preparation quality and working safety of classic NiTi systems was already able to meet high demands, systems still had a potential for development with regard to instrumentation duration and cost effectiveness. This article presents a brief overview of classic NiTi systems and also illustrates recent trends that enable a reduction in the number of instruments through newly developed approaches.
