Effectiveness of Parameters in Quantifying Root Canal Morphology Change after Instrumentation with the Aid of a Microcomputed Tomography
Cross-sectional shape of straight resin simulated root canals at 14 mm coronal from the apex: mean values (standard deviation) of Form Factor, Roundness, and Eccentricity pre- and postinstrumentation with the ProTaper system.
Statistically significant at p<0.05 level.
Statistically significant at p<0.005 level.
ns: not statistically significant (n=10).
