Root fillings with a matched-taper single cone and two calcium silicate–based sealers: an analysis of voids using micro-computed tomography

Objectives To compare the percentage of voids in matched-taper single-cone fillings with GuttaFlow Bioseal or BioRoot RCS root canal sealers, using micro-computed tomography. Materials and methods Forty-eight single-rooted mandibular premolars were prepared using rotary files and randomly allocated...

Description
Summary:Objectives To compare the percentage of voids in matched-taper single-cone fillings with GuttaFlow Bioseal or BioRoot RCS root canal sealers, using micro-computed tomography. Materials and methods Forty-eight single-rooted mandibular premolars were prepared using rotary files and randomly allocated into 2 groups ( n  = 24), wherein the canals were filled with a matched-taper single gutta-percha cone and one of the two sealers: Group 1, GuttaFlow Bioseal and Group 2, BioRoot RCS. The specimens were scanned with micro-CT before and after root canal filling. A specialized software was used to calculate the voids volume percentage (V%) in the filling for the whole root canal, root canal thirds, and the last millimeter from the apex. Data were statistically analyzed by ANOVA and Tukey tests ( p   0.05), while BioRoot RCS group had significantly greater V% in the coronal third compared with the other thirds ( p
