The comparison of strip perforation repair using proroot MTA and calcium silicate-based sealer with cold hydraulic technique; bacterial leakage and micro-CT studies

ProRoot MTA showed the highest proportion of non-leakage samples, followed by iRoot SP and AH Plus, with no significant differences in leakage time. Micro-CT analysis revealed significantly more voids in the AH Plus group. Within the study's limitations, bioceramic sealers showed comparable sealing performance to MTA. Further studies are needed to confirm these findings.
