Apical dye leakage of two single-cone root canal core materials (hydrophilic core material and gutta-percha) sealed by different types of endodontic sealers: An in vitro study

Abstract

Aim of the Study:The aim of this study was to compare the apical sealing ability of two single-cone filling materials when sealed with different types of root canal sealers.Materials and Methods:Eighty extracted maxillary and mandibular canines were selected and their crowns were cut. The root canals were prepared using ProTaper Universal rotary system until size F4 and then divided into seven experimental groups (n = 10 each) and two control groups (n = 5 each). Samples of Groups 1, 2, and 3 were filled with single-cone gutta-percha and AH Plus, MTA Fillapex, and EndoSequence BC, respectively. Samples of Groups 4, 5, and 6 were filled similar to the previous groups with the exception of using a single-cone CPoint. Samples of Group 7 were filled with cold gutta-percha lateral condensation technique. To assess apical microleakage, the apical linear dye penetration was measured microscopically and data were statistically analyzed.Results:All experimental groups showed significantly different dye apical leakage values (P = 0.000). No significant differences were found between Groups 1, 2, 4, 6, and 7 (P < 0.05). The lowest mean leakage value was observed in Group 6 (0.95 ± 0.56 mm) while Groups 3 (2.68 ± 0.71 mm) and 5 (2.61 ± 0.71 mm) showed significantly higher mean leakage values.Conclusions:The lowest apical leakage value was observed with single-cone CPoint/EndoSequence BC but without significant differences when compared with single-cone gutta-percha/AH Plus, single-cone gutta-percha/MTA Fillapex, single-cone CPoint/AH Plus, and lateral condensation technique. Higher apical leakage values were observed with single-cone gutta-percha/EndoSequence BC and CPoint/MTA Fillapex.

Physico-Chemical Properties of Calcium-Silicate vs. Resin Based Sealers—A Systematic Review and Meta-Analysis of Laboratory-Based Studies

“…However, their tabulation and reconfirmation of the results were unclear and sample size for each group was small ( n = 10). As a separate note, El Sayed et al [ 40 ] reported the lowest apical leakage value with the CSBs, however there was no significant difference when compared with the RBS. High solubility of CSBs might raise questions on the long-term sealing ability [ 62 ].…”

“…The main characteristics of the included studies are shown in Table 3 . Ten studies on the adaptation to root canal walls were included [ 30 , 31 , 32 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. In comparison to the RBS, CSBs showed similar values of void volume marginal adaptation in five studies [ 32 , 36 , 37 , 38 , 39 ] whilst at the apical, mid, and coronal thirds, these values were high in three studies [ 31 , 35 , 41 ] and low in one study [ 38 ].…”

“…Four studies were included for the assessment of apical microleakage [ 32 , 40 , 43 , 50 ] in mm with a total of 80 in the CSBs whilst 55 teeth in the RBS groups. Figure 6 demonstrates the forest plot using the random effect model showing standardised mean difference of 6.83 mm favouring the RBS [95% CI 2.90, 10.77] as well as showing statistically significant difference ( p = 0.0007) between these groups.…”

Calcium Silicate-Based Root Canal Sealers: A Narrative Review and Clinical Perspectives

“…A study evaluating apical sealing ability using apical linear dye penetration and comparing AH Plus ® , Endosequence BC ® Sealer™, and MTA Fillapex ® showed the lowest apical leakage value for the SC technique used with the EndoSequence BC ® Sealer™ [ 98 ]. As already shown in the literature, results for the dye techniques remain contradictory, inducing a wide variability.…”

Comparison of the sealing ability of bioceramic sealer against epoxy resin based sealer: A systematic review & meta-analysis

“…Numerous in-vitro and in-vivo investigations present inconsistent and ambiguous results about the proper selection of sealers, ultimately deciding the treatment outcome. Epoxy resin-based sealers 12 , 13 and bioceramic sealers 14 , 15 , 16 , 17 were typically suggested in the investigations on different sealers. Assimilation of all available information from the literature on these materials can assist the practitioner in executing void-free endodontic therapy.…”
