Abstract
The aim of this study was to compare marginal adaptation of Endosequence Root Repair Material (ERRM) and Bio-C Repair, as root-end filling materials. Twenty extracted, single-rooted teeth were standardized to 15 millimeters. The remaining roots were prepared and subsequently, they were filled using the continuous wave technique. Then, the apical 3 mm of the root was sectioned and root-end preparation was done with ultrasonic tips. Samples were randomly allocated in two groups: Group A, in which root-end cavities were filled with ERRM paste; and Group B, in which Bio-C Repair was used for root-end filling. Scanning electron microscope images at different magnifications were used in order to measure the gaps between both retrofilling materials and dentin walls. Results showed that ERRM paste showed a mean gap of 6.43 μm, while for Bio-C Repair, the mean gap was 7.5 μm. Statistical analysis revealed that there were no significant differences between the two groups. In conclusion, Endosequence Root Repair Material paste and Bio-C Repair have similar marginal adaptation when used as root-end fillings.
