Evaluation of Push-out Bond Strength of CeraSeal Bioceramic sealer with Different Obturation Techniques

Abstract

Aim:The aim of this study was to establish a comparison of the push-out bond strength of CeraSeal Bioceramic sealer when used with Gutta percha in single cone (SC), cold lateral compaction (CLC) and warm vertical compaction (WVC) obturation techniques.Materials and Methods: Thirty single-rooted extracted mandibular premolars were selected and mechanically prepared using ProTaper Next rotary system till size X4. The canals were allocated into three equal groups (n=10) based upon the obturation technique as follow; Group I: Bioceramic sealer (CeraSeal) with single cone, Group II: Bioceramic sealer (CeraSeal) with cold lateral compaction technique, Group III: Bioceramic sealer (CeraSeal) with warm vertical compaction technique. Roots were sectioned transversally to a thickness of 1 mm at the middle third. Sectioned root discs were subjected to push-out test using the Universal Test Machine. The maximum load utilised at the time of dislodgment was recorded. Intergroup comparisons were carried out using one-way ANOVA followed by Tukey's post hoc test.Results: WVC group presented the highest statistically significant mean push-out bond strength value (6.98±1.99) followed by CLC group (1.06±0.15), while the lowest value was presented in SC group (0.66±0.22) (p<0.001).Conclusions: CeraSeal Bioceramic sealer showed higher push-out bond strength when used in WVC technique compared to single cone and lateral compaction techniques.

Evaluation of push-out bond strength, dentinal tubule penetration and adhesive pattern of bio-ceramic and epoxy resin-based root canal sealers

“…Sealer found in all four quadrants implies a good adhesive nature, while no sealer indicates better cohesiveness [ 5 ]. In the present study, BioRoot RCS had most type 4 samples ( Table 6 ) following its bonding ability with dentine, as explained earlier [ 10 , 24 , 41 ].…”

“…Despite the presence of calcium silicate as the main component in all the tested sealers, the difference in its percentage or presence of other constituents may have affected the results. Furthermore, different methodologies could also cause value differences among the current study as well as other studies [ 10 , 46 , 47 ]. AH Plus denoted lesser push-out bond strength than BioRoot RCS along with most other calcium silicate-based sealers ( Table 4 ).…”

“…These aluminium-free sealers have good physico-mechanical properties such as biocompatibility, radiopacity, hydrophilicity, and dimensional stability. Moreover, they do not expand or shrink with greater push-out bond strength [ 9 , 10 ]. BioRoot RCS (Septodont, Saint-Maur-des-Fossés Cedex, France), another bioceramic sealer, was introduced in 2016.…”

Marginal Adaptation of Customized Gutta Percha Cone With Calcium Silicate Based Sealer Versus MTA And Biodentine Apical Plugs In Simulated Immature Permanent Teeth (An In Vitro Study)

“…Calcium silicate based (CaSi) sealers have been introduced and characterized by their good penetration into the dentinal tubules, interaction with the dentine moisture, and ability to form a secondary monoblock adhesion when used with gutta-percha for obturation, thereby strengthening the root structure [12]. They also form a mineral layer during their setting, inducing a chemical bond with the dentinal walls and enhancing their sealing ability [13].…”

Comparative evaluation of push-out bond strength of endosequence bioceramic sealer hiflow and endoseal MTA with single cone obturation technique

“…PBS results in shear stress at the dentin-cement interface, comparable with the stress in clinical conditions. 9 The ability of the PBS test to evaluate adhesion is superior to other tests, as it creates parallel fractures in the interfacial area of the dentin bond [10] There are a few studies about the PBS of Endosequence BC Hiflow, Endoseal MTA [7,11] .…”
