Effectiveness of Parameters in Quantifying Root Canal Morphology Change after Instrumentation with the Aid of a Microcomputed Tomography
The mean values (standard deviation) of the ratio of surface area change to volume change and SMI change after the ProTaper instrumentation in straight and curved natural canals.
Statistically significant at p<0.05 level.
Statistically significant at p≤0.01 level.
ns: not statistically significant (n=10).
