Abstract Aim To evaluate the percentage volumes of filling materials and voids in single‐rooted teeth filled with three different filling systems using micro‐computed tomography (micro‐ CT ). Methodology Thirty single‐rooted human teeth were used. After preparation of the root canals, the teeth were randomly divided into three groups ( n = 10). The canals were filled with Endo REZ , ActiV GP or AH Plus/gutta‐percha. Each specimen was scanned using a micro‐ CT device at a resolution of 13.68 μm. Percentage volumes of root filling materials and voids were calculated and data were analysed statistically using the Kruskal–Wallis test and the Mann–Whitney U‐test with Bonferroni adjustment. Within each group, the Friedman test was performed with the Wilcoxon signed‐rank test to detect discrepancies. Results The percentage volume of filling material was significantly lower in the ActiV GP group than in the other groups ( P < 0.05), whilst the percentage volume of voids was significantly higher in the ActiV GP group than in the other groups ( P < 0.05). Conclusion None of the systems were associated with void‐free root fillings. The ActiV GP system had a significantly higher percentage volume of voids than the other systems.
