Aim: The aim of the study was to evaluate the effect of different irrigating solutions used in final irrigation on depth of sealer penetration into dentinal tubules.
Materials And Methods: Thirty recently extracted, human mandibular premolar teeth with single canals were randomly divided into two groups, and one of the two irrigants was used in each group - Group A (Chitosan) and Group B (Ethylenediaminetetraacetic acid). All the teeth were obturated with gutta-percha and AH 26 sealer labeled with fluorescent dye. The teeth were sectioned at distances 2, 5, and 8 mm from the root apex. Maximum depth of sealer penetration was measured using confocal laser scanning microscopy.
Statistical Analysis: Statistical analysis used One-way analysis of variance and -test.
Results: At coronal third depth, the sealer penetration was greater in ethylenediaminetetraacetic acid (EDTA) group; however, depth of sealer penetration was greater at apical third in chitosan group.
Conclusion: Final irrigation with EDTA and chitosan after the use of sodium hypochlorite affected sealer penetration.

Department of Conservative Dentistry and Endodontics, Sri Sankara Dental College, Varkala, Trivandrum, Kerala, India.
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.
Effect of various final irrigation solutions at different temperatures on dentin tubule penetration of bioceramic-based root canal sealer.

Background: To evaluate the effect of 4 final irrigation solutions at different temperatures on dentin tubule penetration of bioceramic-based sealer using the warm vertical compaction method with a laser scanning confocal microscope (CLSM).
Methods: In total, 180 human maxillary incisors were prepared. Different final irrigation solutions [distilled water, ethylenediaminetetraacetic acid (EDTA), peracetic acid, or 1-hydroxyethylidene-1,1-bisphosphonate (HEBP)] at various temperatures (25, 36, or 60˚C) were used.

Background: The micromechanical interlocking between dentinal walls and root canal sealer aids in achieving a three-dimensional impermeable hermetic seal. Calcium silicate-based bioceramic sealers are promising, but their comparative effectiveness in sealing dentinal tubules still needs further research.
Objective: This study evaluated the penetration efficacy of four calcium silicate-based bioceramic sealers - CeraSeal (Meta BIOMED Co.
Bond Strength and Adhesive Interface Quality of New Pre-Mixed Bioceramic Root Canal Sealer.

Department of Restorative Dentistry, School of Dentistry of Ribeirão Preto, University of São Paulo (USP), Ribeirão Preto, SP, Brazil.
To evaluate the bond strength and adhesive interface quality between root dentin and pre-mixed bioceramic sealers: AH Plus Bioceramic, Bio-C Sealer, and NeoSEALER Flo. Thirty-six single-rooted teeth were endodontically treated and divided into three groups (n = 12) based on the sealer used: GI-AH Plus Bioceramic; GII-Bio-C Sealer; GIII-NeoSEALER Flo. Fluorescein dye was added to two samples of each group.
