“…In addition to low solubility, endodontic materials should not have a high percentage of voids (Gandolfi et al 2016), since the presence of voids may increase post-treatment apical periodontitis (Bas ßer Can et al 2017). Hence, the current study also investigated the presence of voids using micro-CT. Micro-CT is a highly accurate, nondestructive tool for measuring voids (Huang et al 2018, Kim et al 2018. A low percentage of voids was detected for the materials.…”

Aim To assess the effect of immersion in distilled water or phosphate‐buffered saline (PBS) on the solubility, volumetric change and presence of voids of calcium silicate‐based root canal sealers (TotalFill BC, Sealer Plus BC and Bio‐C), in comparison with the gold standard epoxy resin‐based sealer (AH Plus). Methodology All properties were evaluated after immersion in distilled water or PBS. Solubility was determined by the percentage of mass loss, whereas volumetric change and presence of voids were evaluated by micro‐computed tomography, after 7 days of immersion. The volumetric change and percentage of voids between the baseline (after setting) and the experimental period were calculated. Statistical analysis was performed using one‐way anova and Tukey's or Student's t‐tests (α = 0.05). Results The calcium silicate‐based sealers had significantly greater solubility and volumetric loss than AH Plus, after immersion in distilled water or PBS (P < 0.05). Bio‐C had the greatest solubility (P < 0.05), followed by TotalFill BC and Sealer Plus BC, which were similar (P > 0.05). Regarding the volumetric change, AH Plus had a volume increase, with similar values in distilled water and PBS (P > 0.05). TotalFill BC, Sealer Plus BC and Bio‐C had a similar volumetric change (P > 0.05). The calcium silicate‐based materials had the greatest solubility and volume loss after immersion in distilled water (P < 0.05). There was no difference in the percentage of voids amongst the sealers, before and after immersion in distilled water or PBS (P > 0.05). Conclusions TotalFill BC, Sealer Plus BC and Bio‐C had significantly greater solubility and volumetric loss than AH Plus. Although storage in PBS significantly reduced the solubility and volumetric change of calcium silicate‐based sealers, their solubility remained above that recommend by ISO 6876. All the sealers evaluated had low and similar voids, even after immersion in distilled water or PBS.

“…Nevertheless, a limitation of the present study was the pixel size of 18 lm applied during micro-CT scanning. Although the image resolution allowed voids to be segmented and quantified, smaller pixel sizes improve image quality and detection of voids (Huang et al 2017, Kim et al 2018.…”

“…Despite being easier to use and requiring less time spent on obturation, according to our previous study, the SC technique may leave several voids in irregularly shaped canals [ 7 ]. These voids are of great concern as they reduce the filling quality and can serve as hubs for microbial housing, leading to reinfection and treatment failure [ 8 ].…”

“…These voids are of great concern as they reduce the filling quality and can serve as hubs for microbial housing, leading to reinfection and treatment failure [ 8 ]. In this respect, we previously introduced a sophisticated method using an ultrasonic-mediated SC technique to reduce void formation [ 7 ]. We showed that the technique was more beneficial to obturate the root canal with less void formation compared to warm vertical compaction.…”

“…While reviewing the papers, we recognized that all the studies were performed only using microcomputed tomography (μCT) but did not observe the sectioned tooth specimens using a microscope. Notably, in our previous study, we suggested that traditional microscopic observation with a suitable scoring system was more reliable than μCT analysis [ 7 ]. In this respect, we felt the necessity to re-evaluate the SC technique’s filling quality compared to the ultrasonic-mediated or warm vertical compaction technique.…”

The present study aimed to investigate the effects of different obturation techniques on the main and accessory canal filling quality of a premixed calcium silicate endodontic sealer (Endoseal TCS). We also highlighted the validity of the methods used for evaluating the canal filling quality. Thirty single-rooted premolars were used for the main canal filling and 75 were used for accessory canal filling. The canals were instrumented and randomly divided into three groups according to the filling techniques: (1) single-cone technique (SC), (2) single-cone with ultrasonic activation (SU), and (3) warm vertical compaction (WV). Voids in relation to the root canal fillings were assessed using cross-section images from microcomputed tomography (μCT) scans or transversely sectioned tooth specimens (n = 10). After demineralization and clearing of the teeth, the incidence, number, and completeness of the accessory canal fillings were evaluated (n = 25). One-way analysis of variance (ANOVA) and Tukey’s post hoc test was used for the evaluation of the voids in the main root canal and the incidence and number of filled accessory canals. Pearson’s chi-squared (χ2) test was used for the evaluation of the filling completeness (α = 0.05). In the stereomicroscopic evaluation of the sectioned specimen, the SC group had significantly higher void occurrence than the other groups (p < 0.05), although there was no difference between groups in the μCT evaluation. However, there was no difference between the SU and WV. There was no difference between all the groups regarding the incidence, number, and completeness of the accessory canal fillings. When the premixed calcium silicate sealer is used with SC, the ultrasonic activation is recommended to obtain a better main canal filling quality. In contrast, the obturation techniques did not affect the accessory canal filling. We also recommend using the sectioning method when the void formation in the root canal filling materials is evaluated.

Root Canal Filling Quality of a Premixed Calcium Silicate Endodontic Sealer Applied Using Gutta-percha Cone-mediated Ultrasonic Activation

Abstract: Endoseal MTA performs best when used with GP cone-mediated ultrasonic activation. Furthermore, stereomicroscopic observation of sections of the specimens should be performed when evaluating root canal filling quality.
