Ultrasonic activation improves bond strength of calcium silicate-based sealers to dentin: an in vitro study

Ultrasonic activation was found to enhance the bond strength of certain sealers in different regions of the teeth, with a notable increase observed, particularly in the apical third, for most of the evaluated sealers. The results suggest that the use of ultrasonic activation may improve bonding performance depending on the sealer. These findings may have clinical implications for optimizing root canal obturation techniques.
