Comparative Micro-CT Evaluation of Dentinal Tubule Penetration of BIO-C and AH Plus Jet Root Canal Sealer Using Three Intra-Canal Activation Techniques.

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 ( = 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.
