The aim of this study was to evaluate the ability of three obturation methods to seal root canals prepared using 0.06 taper rotary instruments. Forty‐five extracted human single‐rooted teeth were instrumented with 0.06 taper Profile nickel‐titanium rotary files and randomly divided into three experimental groups containing 15 teeth each. The first group was obturated using the System B technique with 0.06 taper standardised gutta‐percha points, the second group was obturated using the System B technique with non‐standardised MF guttapercha points, the third group was obturated by cold lateral condensation technique using standardised 0.02 taper master gutta‐percha points. Apical leakage of the roots was evaluated by dye penetration using a stereomicroscope after sectioning the roots. The group obturated using System B and 0.06 taper guttapercha points showed the least dye penetration. However, the difference in the linear extent of dye penetration was not statistically significant.
