BacKGrOUND: to evaluate the voids percentage and the retreatability by different supplementary irrigation tech- niques of a matched-taper single cone and epoxy resin-based sealer. METHODS: A total of 72 single-rooted premolars were prepared and filled with gutta-percha and MM-Seal. The per- centage of voids in the whole root canal and each anatomical part were evaluated by Micro-CT scans. After root filling removal, the teeth were randomly allocated (N.=24) to group a, syringe irrigation; group B, tornado Brush, and group C, ultrasonically activated irrigation and re-scanned to establish the volume of remnant root filling material. The data relative to voids and retreatment techniques were established by the Kruskal-Wallis test. Differences in retreatment time were examined using one-way aNOVa and tukey’s test (P<0.05). RESULTS: No significant difference was found in the voids percentage between the different root-thirds and between the supplementary irrigation groups in the MM-Seal remnants for the whole root canal and each section. in all groups, the coronal region exhibited more remaining material than other sections. CONCLUSIONS: MM-Seal showed low voids percentage and its removal was not significantly improved by supplemen- tary irrigation techniques.

Abstract

BacKGrOUND: to evaluate the voids percentage and the retreatability by different supplementary irrigation tech- niques of a matched-taper single cone and epoxy resin-based sealer. METHODS: A total of 72 single-rooted premolars were prepared and filled with gutta-percha and MM-Seal. The per- centage of voids in the whole root canal and each anatomical part were evaluated by Micro-CT scans. After root filling removal, the teeth were randomly allocated (N.=24) to group a, syringe irrigation; group B, tornado Brush, and group C, ultrasonically activated irrigation and re-scanned to establish the volume of remnant root filling material. The data relative to voids and retreatment techniques were established by the Kruskal-Wallis test. Differences in retreatment time were examined using one-way aNOVa and tukey’s test (P<0.05). RESULTS: No significant difference was found in the voids percentage between the different root-thirds and between the supplementary irrigation groups in the MM-Seal remnants for the whole root canal and each section. in all groups, the coronal region exhibited more remaining material than other sections. CONCLUSIONS: MM-Seal showed low voids percentage and its removal was not significantly improved by supplemen- tary irrigation techniques.
