Evaluation of the Effect of Different Antioxidants on Resin Bond Strength to Enamel after Bleaching: An Study.

Aim: To compare and evaluate the efficacy of 10% sodium ascorbate (SA) solution, 10% alpha-lipoic acid (ALA) solution, 10% propolis solutions (PLS), and 10% pomegranate peel extract (PPE) solution on the shear bond strength (SBS) between composite resin and bleached enamel after 60 minutes.

Materials And Methods: Ninety extracted teeth were divided into 6 subgroups ( = 15) based on the antioxidant applied: Group I: Bleaching + application of 10% SA solution for 60 minutes. Group II: Bleaching + application of 10% ALA solution for 60 minutes.

An Investigation of the Sealing Ability of Biodentine and Mineral Trioxide Aggregate as Retrofilling Materials after the use of Various Irrigating Solutions.

Aim: The purpose of this study was to assess the sealing ability of Biodentine (BD) and mineral trioxide aggregate (MTA) as retrograde filling materials after irrigation with 17% ethylenediaminetetraacetic acid (EDTA) and QMix irrigating solutions.

Materials And Methods: Decoronation of 48 permanent maxillary central incisors was done. Root canal instrumentation was carried out in the samples.

Apical Extrusion of Intracanal Bacteria following use of Two Engine-driven Instrumentation Techniques: An in vitro Study.

Aim: The aim of the present study was to compare in vitro the amount of debris extruded apically from extracted teeth, using Twisted files and ProTaper rotary during two different instrumentation systems.

Materials And Methods: Forty-five human single-rooted mandibular premolar teeth were randomly divided into three groups and contaminated with Enterococcus faecalis. The teeth in experimental groups were instrumented until reaching the working length with ProTaper rotary instruments and Twisted files with XSmart and XSmart Dual groups.
