Abstract
Objectives: The purpose of this study was to compare the sealing ability of different glass ionomer cements (GIC) as root-end filling (RF) materials. Materials and Methods: One-hundred and eleven extracted human canines were cleaned and prepared using a rotary nickel titanium files with crown-down technique. All the teeth were filled with gutta-percha and then the apical third of each root was resected perpendicularly to the long axis direction. After, root-end cavity was prepared using a round bur. The specimens were randomly divided into 7 groups of 15 samples, filled with one of the test materials (Ionofil, Ketac Molar Quick Aplicap, Argion Molar AC, Photac Fil Quick Aplicap, Fuji II LC Capsule, Dyract Extra, Glasiosite Caps) and were stored at 37°C and 100% humidity for 7 days. 1-week later, apical parts of roots of 10 ± 0.05 mm were attached to the computerized fluid filtration device. The data obtained were analyzed using an ANOVA and post hoc Tukey's tests (P ≤ 0.05). Results: Statistical analysis indicated that RF with Argion molar AC (reinforced GIC) had the least micro-leakage of all and whereas Ketac Molar Quick Aplicap (conventional GIC) showed highest apical leakage than the other groups. Conclusion: This present study has shown that none of GICs, which used as a RF material unable to prevent apical leakage exactly and Argion Molar AC is used as a RF material among current GICs better than others.
