Effectiveness of Parameters in Quantifying Root Canal Morphology Change after Instrumentation with the Aid of a Microcomputed Tomography

Figure 1

Bidirectional movement of SMI values, demonstrated by instrumentation on straight and curved resin simulated root canals. Bars represent statistical differences at p<0.01 level and p<0.001 level amongst groups of untreated, F1 prepared, and F2 prepared roots.
