Comparative Dentinal Tubule Penetration of Three Calcium Silicate-Based Sealers Under Conventional and Sonic-Activated Final Irrigation Protocols: An In Vitro Confocal Microscopy Study
Background: Successful root canal treatment depends on achieving an effective three-dimensional seal and limiting microbial persistence and reinfection. Dentinal tubule penetration may enhance sealing by increasing sealer–dentin contact and micromechanical retention. This study compared the dentinal tubule penetration...
