“…This in vitro study was conducted on BioRoot™ RCS root canal sealer (BioRoot™ RCS, Septodont, Saint-Maur-des-Fossés, France). In Table 1, the initial materials’ specifications, manufacturers, and composition used to manufacture the different composites used in this experiment were listed and reproduced from the study by Baghdadi et al 27 The nanomaterials that were added into the sealer were: multi-walled carbon nanotubes (MWCNTs) with an internal diameter of 3–5 nm, an external diameter of 6–13 nm, titanium carbide (TC) nano-powder with diameter ˂200 nm, and boron nitride nanotubes (BN) with diameter ˂300 nm. All of the ingredients were the products of Millipore Sigma, Burlington, MA, USA, and were used without any additional refinement.…”

“…In order to produce a homogenous mixture, milling was carried out for each composite using first a speed of 300 rpm for a period of 10 min followed by another cycle at a speed of 100 rpm for 50 min. 28,29 In order to harden the composite powder, the liquid solution of Bioroot was added to each composite at room temperature and with of 1:5 (powder to liquid) ratio following the instructions of the BioRoot™ RCS manufacturer. To be able to mix all the powder, an additional drop of liquid was needed in the 2-wt.% composites.…”

Objectives: A root canal sealer that can increase the resistance of endodontically treated teeth to compressive strength would be of great advantage. The purpose of this study is to use three different nanoparticles: multi-walled carbon nanotubes (MWCNTs), Titanium carbides (TC), and Boron nitrides (BN) into a bioceramic adhesive root canal sealer; BioRoot™ RCS, in an attempt to improve its structural and compressive strength properties. Methods: Three composites of two weight fractions (1- and 2-wt.%) were produced by mixing each nanomaterial separately with a pre-weighed mass of Bioroot powder. The microstructural properties and compressive strength of the different hardened composites obtained were investigated. The composites have been characterized by X-ray Diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. Compression testing was performed. Results: The 1-wt.% composites, Bioroot/MWCNTs, and Bioroot/TC, except for the one reinforced with BN, displayed a significant improvement in the compressive strength compared to pristine BioRoot™ RCS. The 2-wt.% composites showed no significant improvement in the compressive strength. Conclusion: The addition of 1-wt.% MWCNTs and TC nanomaterials can be considered in the future for enhancing the microstructure and compressive strength properties of pristine BioRoot™ RCS.
