Abstract:
Aim: Using two obturation techniques: continuous wave condensation (CWC) and cold lateral condensation (CLC), this study compares the capacity of calcium silicate-based root canal sealers (Well Root ST) and nanoparticle-based sealers (Nano-ZNO-based sealers) to fill artificial lateral canals (ALC).
Methodology: Eighty human mandibular premolar teeth with single roots were decoronated and standardized to 16 mm length. Instrumentation was done using the PLEX-V system rotary file system up to PLEX-V 40.04. Three artificial lateral canals (ALCs) were created using an ED15 endodontic ultrasonic on the mesial and distal surfaces, perpendicular to the longitudinal axis of the roots. The samples were randomly assigned to one of two experimental groups according to the sealer used. Two subgroups were created from each group based on obturation techniques. Digital radiography was used to assess the artificial lateral canal filling capacity following obturation, which was achieved using EzDent-i software. The ranking score system was used and recorded, then saved on the computer. Data collected and statistically analyzed.
Results: Between the four treatment groups, there was a significant difference (p < 0.001).
Conclusion: It can be concluded that the obturation by CWC using a nano-ZNO-based sealer is effective in the obturation of lateral canals, which are located in the apical third. The highest rate of filling of ALC is in coronal third. The apical third was associated with the lowest acceptable filling.
