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 (n = 20): group A, ultrasonic activation; Group B, sonic activation; and Group C, single-cone technique. Penetration of the fluorescently labeled biosealer was investigated using a confocal laser scanning microscope. Results: The data were statistically analyzed using Kruskal-Wallis and Mann-Whitney tests (P = 0.05). The highest penetration of biosealer was observed in Group A, followed by Group B (P < 0.05). Conclusions: Dentinal tubule penetration of biosealer was significantly improved by ultrasonic and sonic activation techniques.

Abstract

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 (n = 20): group A, ultrasonic activation; Group B, sonic activation; and Group C, single-cone technique. Penetration of the fluorescently labeled biosealer was investigated using a confocal laser scanning microscope. Results: The data were statistically analyzed using Kruskal-Wallis and Mann-Whitney tests (P = 0.05). The highest penetration of biosealer was observed in Group A, followed by Group B (P < 0.05). Conclusions: Dentinal tubule penetration of biosealer was significantly improved by ultrasonic and sonic activation techniques.
