Abstract
Background
Awareness about the vital role the root canal sealer plays in acquiring a three-dimensional seal necessitates continual work to develop a material that encompasses the intended physical, chemical, and biological properties. Therefore, the present study was designed to assess the sealing ability of MTApex powder/liquid and TotalFill ready-to-use calcium silicate-based formulas via measuring their adaptation and bond strength to the root canal wall. The potentiality of root canal sealer to adapt and bond with dentin wall is a suggestive caliber for obturation quality assessment. Calcium silicate-based root canal sealers gained broad acceptance due to their distinctive properties and clinical performance. MTApex is a novel calcium silicate-based root canal sealer in powder/water-based gel liquid component, which is claimed to show improved performance.Materials and methods
Thirty extracted teeth were assigned for the study. After chemomechanical preparation, the samples were separated into group I that used (TotalFill BC), and group II that utilized (MTApex) for obturation with F3 gutta-percha matching cone. Moreover, three sections of 2mm thickness were provided from each sample; and each section was assessed by Scanning Electron Microscope and Universal Testing Machine for sealer adaptation and push-out bond strength assessment, respectively. Inter-group statistically significant difference was detected via using Mann-Whitney U test, while intra-group statistical analysis was performed using Kruskal-Wallis test. Then, pairwise comparisons were done using Mann-Whitney U test with Bonferroni correction, which detected significant differences (P≤0.05).Results
Statistically, the lowest gap diameter and the highest push-out bond strength records were reported by TotalFill root canal sealer, compared to MTApex, concerning the three root sections. The coronal root section revealed lower gap diameters and higher push-out bond strength record; this is in comparison to the other sections (P≤0.05).Conclusions
MTApex demonstrated adaptation and bond strength lower than that of TotalFill. Nevertheless, inconsistent adaptation and bond strength were reported regarding the different assessed sections, where a high level of adaptation and bond strength was detected in the coronal section, middle section, and apical section, respectively.
