- To demonstrate the importance of dentin preservation, especially the pericervical dentin
Abstract
During the shaping of root canal systems, the clinician faces many challenges. Some of them are related to the instrumentation per se, but many times are conditioned by the internal anatomy or access design. These drawbacks could lead to iatrogenic errors, as ledges, blockages or canal transportation.
In the last few years the concept of “minimally invasive endodontics” has been emphasized in the literature and scientific forums. It means that new concepts are being applied to the instrumentation of the root canals. New alloys and file designs have made possible new approaches even to complex anatomies where the classic mechanical instrumentation sometimes needed of an excessive removal of root structure during our treatments, something that could affect the outcome.
