Analysis of the depth of penetration of an epoxy resin-based sealer following a final rinse of irrigants and use of activation systems: An study.

Objective: The objective of the study was to compare and evaluate the depth of penetration of an epoxy resin-based sealer following a final rinse of 17% ethylenediaminetetraacetic acid (EDTA) and 18% 1-hydroxyethylidene 1, 1-diphosphonate (HEDP), with diode laser and passive ultrasonic activation (PUI): an confocal laser scanning microscopy study.

Materials And Methods: Fifty-two extracted human mandibular premolar teeth with single root and single canal were selected. They were disinfected in 0.

Comparative Evaluation of Cytotoxic and Genotoxic Effects of Three Resin-Based Sealers by 3,(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide Assay and Comet Assay - An In Vitro Study.

Background And Aim: The complete sealing of the pulpal space contributes to the better healing potential after an root canal treatment, and root canal sealers are an integral part of this treatment which comes in contact with the periodontal tissue. Biocompatibility of an endodontic sealer plays an important role in the root canal treatment procedure. Hence, the aim of the study was to compare and evaluate the cytotoxicity and genotoxicity effect of three resin-based sealers on human periodontal fibroblast cells.

Evaluation of the Effect of Long-term Use of Three Intracanal Medicaments on the Radicular Dentin Microhardness and Fracture Resistance: An study.

Objectives: The aim of this research was to evaluate the effect of long-term use of three intracanal medicaments on the radicular dentin microhardness and fracture resistance.

Material And Methods: A chemomechanical preparation was done using the Protaper rotary instruments up to F3. The teeth were stored in an incubator at 37°C at 100% humidity and were categorized in three groups by random allocation, namely: Triple Antibiotic Paste (TAP), Calcium hydroxide paste (Apexcal) and Ledermix.

Evaluation of Push-out Bond Strength of a Resin Sealer to Dentin after a Final Flush of Three Irrigants.

Aim: To evaluate the push-out bond strength of resin-based sealer to root dentin after a final flush of three different irrigants.

Materials And Methods: Thirty extracted human mandibular premolars were sectioned 4 mm below the cement-enamel junction and 60 horizontal disks of 2 mm from middle one-third of the root were prepared. The disks were immersed in 3% sodium hypochlorite for 1 minute, and after drying the disks, they were finally flushed with the following irrigants: group I-Chitosan solution, group II- juice (MCJ), and group III-ethylenediaminetetraacetic acid (EDTA).
