“…Additionally, within the same procedure, all three obturation techniques showed significant penetration into the root dentin at the coronal level, and the middle and final levels of penetration were at the apical level ( Wang et al, 2018 ). The TotalFill BC Sealer HiFlow bioceramic achieves higher penetration in the warm continuous wave and vertical condensation techniques compared to the cold single-cone technique ( Casino Alegre et al, 2022 , Yang et al, 2021 ); the area with the highest penetration is the coronal, followed by the middle and apical areas. Yang et al ( Arikatla et al, 2018 ) investigated the single cone and continuous wave techniques using two calcium silicate cements, HiFlow and iRoot SP®, as well as the resin sealer AH Plus®.…”

“…According to Roussel [48], based on the hydration reaction, the adhesive interaction of hydroxyapatite to root dentin occurs by integrated bonds between the sealer and bioceramic gutta percha cones, forming a unique network with covalent bonds between the calcium silicates and water, thereby allowing a three-dimensional lling, and consequently, increasing the bond strength [51]. This interaction of the bioceramic material is responsible for the elimination of empty spaces and consequent reduction of uid penetration into the adhesive interface [27][28][29][30]42] as observed in the present study in the SEM photomicrographs. This made it possible to verify the more uniform and thinner endodontic sealer layer in the bioceramic gutta percha cones, with a prevalence of mixed failures and the presence of gaps ranging between 1 µm and 10 µm at the adhesive interface.…”

“…By chemical a nity, these are able to form a layer of bioactive components that help with the bond between the lling sealer and the root dentin, generating a byproduct of the biomineralization reaction between the dentin wall and calcium and hydroxyl ions [23][24][25][26]. This bioactive layer is responsible for eliminating the voids and uid penetration at the bond interface [27][28][29][30]. Recently, gutta percha cones were developed.…”

Aim To evaluate the bond strength (BS) and analysis of the adhesive interface in root canals filled with bioceramic gutta percha sealers and cones. Material and Methods Ninety-six maxillary canines were divided into eight groups according to the endodontic sealer (AH Plus, AH Plus Bioceramic, Bio-C Sealer or Bio-C Sealer Ion + and gutta percha cones (conventional or bioceramic) tested. They were analyzed using the BS test, failure pattern, analysis of the adhesive interface by scanning electron microscopy and confocal laser scanning microscopy. The BS data were compared between groups using the analysis of variance test with the Turkey post-test. The chi-square test was used to assess the type of failure and the non-parametric Mann-Whitney and Kruse-Wallis tests (p < 0.05). Results Analysis of variance showed higher BS values for the groups of bioceramic gutta percha cones in Bio-C Sealer Ion+ (8.38 ± 4.27), AH Plus Bioceramic (6.19 ± 3.28), Bio-C Sealer (5.70 ± 3.18), AH Plus (4.61 ± 2.11) and for conventional gutta percha cones in AH Plus sealers (4.26 ± 2.35), Bio-C Sealer Ion+ (3.63 ± 2.29), Bio-C Sealer (2.94 ± 2.32) and AH Plus Bioceramic (1.19 ± 0.89) (p < 0.05). Relative to the type of failure and adaptation of the types of filling material, a higher percentage of mixed failures was observed (gaps between 1 µm-10 µm) for the group with bioceramic gutta percha cones (p < 0.001). Conclusion The bond between sealers and bioceramic gutta percha cones showed higher bond strength values and greater penetration into the dentin tubules. Clinical Relevance: The filling the root canal system with bioceramic sealers should be associated with bioceramic gutta percha cones.

“…The ineffective delivery of irrigant to the apical third of the canal, the smaller diameter, and the reduction in the number of dentinal tubules in this region may explain the poorer sealer penetration in the apical third [ 27 ]. Areas of sclerotic dentin are more dominant, rendering the apical region of the tooth less permeable than the coronal region [ 36 , 37 ]. According to Alegre et al [ 38 ], the differing pressures, depth, and heat of the pluggers applied during obturation could also explain the lower degree of sealer penetration in the apical third rather than the coronal third.…”

Background This study aimed to evaluate the effect of various irrigation protocols on the penetration depth of a calcium silicate–based sealer into dentinal tubules using confocal laser scanning microscopy (CLSM). Methods Twenty single-rooted mandibular premolars were endodontically prepared and divided into the following two groups according to the irrigation protocol used (n = 10): Group I: NaOCl + EDTA and Group II: continuous chelation (NaOCl/Dual Rinse). Obturation was performed with the warm vertical compaction technique using TotalFill HiFlow bioceramic sealer mixed with a fluorophore dye. Samples were observed using CLSM at 10× to measure the percentage of sealer penetration and its maximum depth into the dentinal tubules. Data were analysed using one-way ANOVA followed by Tukey’s post-hoc test. The significance level was set at p < 0.05 within all tests. Results Comparing the overall results of all sections tested, no statistically significant differences existed between the groups regarding the percentage of sealer penetration (p = 0.612) and maximum depth of penetration (p > 0.05). Conclusions With both types of irrigation used, dentinal tubule penetration was higher in the coronal section than in the apical section. Continuous chelation using NaOCl/Dual Rinse HEDP performed better in the coronal segments, while irrigation using NaOCl + EDTA promoted a higher percentage of sealer penetration in the apical segment.
