Root Canal Negotiation MB2 (simulated)

Instrumentation of root canal systems ideally involves a repeating series of steps regardless of whether one is in the coronal, middle, or apical third. These steps include a cycle of negotiation (or at least assurance that the canal is negotiable given the particular anatomy).As a first step, the negotiation is most often essential, particularly in the apical third. Small K files (6-10s), used for negotiation, should be precurved and placed into the given canal third to explore the canal for curvature, calcification, diameter, ease of insertion, length etc. Negotiation might be thought of as the process of exploration and discovery to determine the individual canal anatomy noted previously.
