“…[ 13 ] reported that marginal adaptation was less in all groups based on SEM images in the apical part compared to the middle and coronal parts. Remy et al ,[ 14 ] by evaluation the AH plus sealer, also reported that the marginal adaptation of the apical region was significantly lower than the coronal region. In the present study, it was observed that the depth of tubular penetration was not affected by the filling method; however, it was significantly higher in the use of bioceramic sealer than epoxy resin ( P < 0.001).…”

Introduction and Objective The proper performance of a sealer in root canal treatment depends on its physical properties. The aim of this study was to investigate the effect of two bioceramic and epoxy resin sealers in terms of marginal adaptation and tubular penetration depth in different obturation methods of human premolar teeth. Materials and Methods A total of 82 premolar teeth extracted due to caries and gum disease were used in the present in vitro experimental study. Two types of sealers, epoxy resin (AH-Plus, Dentsply, Germany) and bioceramic (Endosequence BC sealer, Brasseler, Savannah, GA, USA), were used in this research. Lateral compaction and single-cone techniques were used for filling the teeth. Marginal adaptation and tubular penetration depth were measured by scanning electron microscopy (SEM) and confocal laser scanning microscope (CLSM), respectively. Statistical analysis of data was performed by repeated-measures ANOVA. The significance level was considered as P < 0.05. Results The marginal adaptation and tubular penetration depth in all three coronal, middle, and apical regions were better in bioceramic sealer ( P < 0.001). The marginal adaptation and tubular penetration depth in all regions were not affected by the filling method and the interaction between the sealer type and the obturation technique. Conclusion Based on the results of this study, the use of bioceramic sealer caused better depth of tubular penetration and marginal adaptation compared to epoxy resin. Further studies and the use of different filling techniques are necessary to achieve a three-dimensional sealing in curved root canals.

“…The adaptation to root canal walls was evaluated using the marginal adaptation, interfacial gaps and void volume in cubic millimetres with mean percentages. The marginal adaptation [ 31 , 48 ] and interfacial gaps [ 39 , 53 , 55 ] were assessed using the Scanning Electron Microscope whereas void volume [ 30 , 41 , 42 , 47 , 51 ] was assessed by Micro-computed Tomography. Kim et al [ 30 ] stated that the voids in the root canal obturation might weaken the filling quality and serve as a hub for microbes by transporting contaminants along the root canal system.…”

“…Various studies reported that RBS could penetrate deep into the dentinal tubules due to the flowability, long setting time, and provide long-term dimensional stability [ 48 , 53 , 57 , 58 ]. Germain et al [ 41 ] suggested that EndoSequence (CSBs) reduced film thickness, improved flow and hardening on contact with moisture within the root dentine.…”

Introduction: The aim of this systematic review is to analyse the effect of physico-chemical properties of calcium silicate-based sealers in comparison to epoxy resin sealers in permanent teeth using a single-cone obturation technique. Methods: The study was conducted according to the guidelines of Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. Literature search was performed using the PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, DOAJ, Open Gray with no language restrictions until October 2020. Two reviewers assessed the studies for eligibility. Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) was carried out to assess the evidence. Meta-analysis of the pooled data with subgroups was performed using the RevMan software (p < 0.05). Results: Results from the 28 included studies showed that the mean difference in adaptation to root canal walls (marginal adaptation, interfacial gaps and void volume) for both sealers were non-significant. However, void volume values showed a significant mean difference (p < 0.00001) favouring the calcium silicate-based sealers. The pooled meta-analysis reported statistically significant differences for apical microleakage (p = 0.0007) whilst there were non-significant mean differences for fracture resistance (p = 0.09) and push-out bond strength (p = 0.63). The heterogeneity among the included studies was 97% (I2). Conclusions: Within the limitations of this review, calcium silicate-based sealers demonstrated a similar or superior performance in comparison to resin-based sealers in terms of the physico-chemical properties.

“…Endodontic sealers have a key role in sealing the root canal system, entombing the residual bacteria, and filling the irregularities in the prepared canal system [13]. The adhesion between the root canal dentin and GP is important in preventing microleakage, which can be attained through the use of different sealers [14]. Therefore, sealers have a great effect on the sealing of the canal space and the success of treatment.…”

Background:The most desirable outcome of endodontic treatment is to achieve a fluid-tight seal of the root canal space. Root canal sealers are used in combination with core filling materials to fill the irregularities in the root canal, resulting in a three-dimensional seal that prevents bacterial regrowth. Aim: This study was aimed to compare the apical sealing ability of three root canal sealers AH Plus, Endosequence BC, and Endoseal MTA, using a single cone gutta-percha obturation technique. Materials and methods: Forty extracted human single-rooted mandibular premolar teeth were decoronated to a standardized length of 15 mm and instrumented using crown down technique with the ProTaper gold rotary file system to apical file size F3. The roots were randomly allocated into three experimental groups (n=10) and two control groups (n=5). All the samples in experimental groups were obturated with a matched taper single cone: Group 1, Group 2 and Group 3 were obturated using AH Plus, Endosequence BC and Endoseal MTA sealers, respectively. Samples were immersed in 1% Methylene blue dye solution for 72 hours, and then the roots were split longitudinally and observed under a stereomicroscope. Apical microleakage was measured from the apex to the most coronal level of dye penetration. The data obtained were subjected to statistical analysis. Results: Samples in all the groups showed evidence of leakage, except in the negative control group. One-way ANOVA showed significant differences between the groups (p=0.00132). Posthoc analysis exhibited a significant difference between group 2 and group 3 (p=0.0102). Conclusion: Endosequence BC showed a superior seal and less microleakage compared to the two other sealers used in this study using a single cone guttapercha obturation technique.
