Objectives:
This study aimed to compare the effectiveness of three intra-canal sealer activation techniques: ultrasonic, Lentulospiral activation, and GP cone-mediated ultrasonic activation on dentinal tubule penetration of a bioceramic (BIO-C) root canal sealer and AH Plus jet sealer with single cone obturation.
Materials And Methods:
Eighty single-rooted straight canal teeth were randomly divided into two main groups - BIO-C sealer and AH Plus jet sealer (n = 40). Each group was further divided into four subgroups, based on the three activation techniques: ultrasonics, Lentulospiral, gutta-percha cone-mediated ultrasonic, and a control. The canals were obturated using the single cone obturation technique. Dentinal penetration of sealers was measured using Micro-CT at the coronal, middle, and apical portions of root canals.
Results:
Greater sealer penetration was observed with ultrasonic and Lentulospiral agitation compared to GP-mediated ultrasonic agitation for both sealers.
Conclusion:
BIO-C yielded better results with ultrasonic and Lentulospiral agitation, while AH Plus performed better with ultrasonic agitation.
