Abstract:
The aim of this preliminary study was to compare two core-carrier obturation techniques-GuttaFusion (GF) and SoftCore (SC)-used in combination with a bioceramic sealer (NeoSealer Flo), and to evaluate their ability to fill simulated root canals. Eight standardized resin models of maxillary first molars were used, and only the P and DV canals of each model were obturated. Cross-sections were obtained at 1 mm and 3 mm from the apex, and the percentage areas occupied by gutta-percha (PGFA), sealer (PSFA), and voids (VA) were measured. This study provides novel comparative data on the performance of these two carrier-based techniques when used with a bioceramic sealer. GF showed higher PGFA and lower PSFA compared with SC at 1 mm from the apex, while SC presented slightly higher VA. At 3 mm, PGFA increased for both techniques. Descriptive statistics (means and percentage values) were calculated; no inferential statistical analysis was performed due to the preliminary nature of the study and the limited sample.
