Dentinal tubule penetration following ultrasonic, sonic, and single-cone technique of a biosealer: An study.

Background: The endodontic space is complex, and using a single-cone obturation technique fails to ensure a complete filling.

Introduction: This study aimed to investigate the effect of ultrasonic activation, sonic activation, and single-cone technique of a biosealer on its dentinal tubular penetration.

Materials And Methods: In the experiment, single-root mandibular premolars were randomly assigned to three groups ( = 20): group A, ultrasonic activation; Group B, sonic activation; and Group C, single-cone technique.
