“…The presence of calcium may favour an alkaline pH, which is directly related to antimicrobial activity and repair by hard tissue deposition (Torabinejad et al, 2018). In general, calcium silicate‐based materials have alkaline activity and a high pH (Coaguila‐Llerena et al, 2020). Despite the greater release of calcium ions to BCT compared to BD and BCR, in the present study, all materials had a similar slightly alkaline pH.…”

“…In the present study, the null hypothesis was rejected, as significant differences were found between the calcium silicate-based materials in most of the evaluated parameters. Although previous studies have evaluated BD using similar methodologies (Adl et al, 2019;Farrugia et al, 2018;Marconyak et al, 2015;Ochoa-Rodrıguez et al, 2019;Ochoa-Rodriguez et al, 2020;Oliveira et al, 2020;Shokouhinejad et al, 2016;Vallés et al, 2015;Yoldas et al, 2016), few studies have used BCT (Guerreiro et al, 2021;Oliveira et al, 2020;Villa et al, 2020) and BCR (Benetti et al, 2019;Ghilotti et al, 2020;López-García et al, 2019), which are new ready-to-use materials. To assess crown discolouration by these materials in the presence of blood components, a model was designed to simulate the clinical situation of partial pulpotomy.…”

“…Despite having the same radiopacifier, BD and BCR exhibited different radiopacity in both experimental time periods, which is probably related to the percentage of zirconium oxide. Previous studies have revealed low radiopacity for BD (Farrugia et al, 2018;Ochoa-Rodrıguez et al, 2019;Ochoa-Rodriguez et al, 2020). However, it is not possible to make comparisons between different radiopacity studies because several factors may interfere with the results, such as the X-ray machine, exposure time, tube voltage, source-to-object distance, conventional radiography and digital radiography systems (Ochoa-Rodrıguez et al, 2019;Ochoa-Rodriguez et al, 2020).…”

Aim To analyse the discolouration, radiopacity, pH and calcium ion release of Biodentine (BD), Bio‐C repair (BCR) and Bio‐C temp (BCT), as well as their biological effects on human dental pulp cells (hDPCs). Methodology Sixty‐four extracted bovine incisors were prepared to simulate crown fractures with pulp exposure and open root apex. The roots were filled using a mixture of agar and blood (control), and BD, BCR or BCT were placed over this mixture. Colour assessment analyses of the samples were performed before and immediately after material insertion and repeated at 30 and 90 days, using a spectrophotometer. The colour change of each specimen was evaluated at the crown and calculated based on the CIELab colour space. Digital radiographs were acquired for radiopacity analysis. hDPCs were placed in contact with different dilutions of culture media previously exposed to such materials and tested for cell viability using the MTT assay. The pH and calcium ion release of all materials were measured after 24 h; the data were assessed using one‐way analysis of variance (ANOVA). Cell viability was analysed by two‐way ANOVA. Differences in colour parameters and wound‐healing data were assessed by two‐way repeated measures ANOVA (α = 0.05). Tukey's and Dunnett's tests were used to compare the experimental groups with the control group. Results BCR had grater radiopacity and smaller colour alteration (ΔEab/ΔE00) than the other materials tested (p < .005; p < .001). No significant differences in pH were found amongst the tested materials (p > .05). BCT was associated with the largest release of calcium ions (p < .0001). BD had cell viability similar to that of the control at the lowest dilutions, and BCR was similar to that of the control, regardless of the dilution tested (p > .05). BCT had a lower percentage of viability than that of the control at all tested dilutions (p < .0001). Cell migration rates in BD and BCR were similar to those in the control group after 24 h and 48 h (p > .05), whilst BCT had larger voids than the control in both periods (p < .0001). Conclusions BCR, BCT and BD were associated with tooth discolouration. BCR had the lowest staining values, the highest radiopacity and viability greater than 80% hDPCs.

“…Since Biodentine includes more biocompatible zirconium oxide as a radiopacifying material, it remained below the radiopacity value speci ed in ISO 6876:2001. For BioMTA, the 20-30% calciumzirconium oxide complex eliminated the disadvantage of Biodentine and showed results above the radiopacity value speci ed in ISO 6876:2001 [23]. In this study, BioMTA showed signi cantly higher radiopacity than Biodentine, which can be attributed to using a calcium-zirconium oxide complex in BioMTA.…”

Background The aim of this study was to compare the radiopacity of calcium silicate sealers using a digital imaging method. Methods Four calcium silicate-containing sealers, NeoMTA2, BioMTA, ProRoot MTA, and Biodentine, were used in this study. Standard disk-shaped samples were prepared from each root canal filling material and placed on a plexiglass plate. An aluminum penetrometer was placed on a digital radiograph to obtain the irradiation parameters of 70 kVp, 8 mA, and 0.32 seconds. The object-beam distance was adjusted to 30 cm. The grayness values of the tested materials were measured digitally with the system software and compared with a penetrometer to determine the equivalent aluminum thickness. Results The radiopacity values of the studied materials in decreasing order, expressed in millimeters of aluminum equivalent, were ProRoot MTA (4.32), Biodentine (2.29), Bio MTA (3.92), and NeoMTA2 (3.83). Statistically significant differences were found between the mean radiographic density values of the tested materials (p < 0.005). Conclusion ProRoot MTA was the most radiopaque root canal filling material among the tested materials in this study. All materials, except Biodentine, are compliant with the minimum radiopacity standard recommended by the International Organization for Standardization and the American National Standards Institute/American Dental Association.

“…Previous studies have shown that the cement has improved flexural strength when the setting reaction takes place in the presence of moisture [4]. MTA Angelus and NeoMTA differ mainly in their opacifier composition, with the presence of bismuth oxide in the former and tantalum oxide in the latter [6,7].…”

Background: The placement of a wet cotton pellet against Mineral Trioxide Aggregate (MTA) is often recommended to ensure the completion of its setting reaction. Objective: This study aimed to evaluate the setting behaviour of MTA Angelus and NeoMTA by comparing their hardness after placing them in dry and moist conditions. Methodology: A simulated open apex was created on 40 polyvinyl tubes. The apical 4 mm of the tubes was filled with the two materials, NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA) and MTA Angelus (Angelus, Londrina, PR, Brazil) (n=20 per group). Both groups were subdivided into two subgroups based on the dry and wet conditions (n=10 per group). A wet cotton pellet was placed above the two materials in the wet group, and the coronal segment was sealed using Type II Glass ionomer cement (GC corporation Tokyo, Japan). Gutta-percha was placed against the test materials in the dry group with the coronal segment sealed with amalgam. Samples were placed in an oasis soaked in phosphate-buffered saline for seven days in 100% humidity and at 37°C. Microhardness was measured independently at 4 and 2 mm from the apex. Hardness was compared between materials and conditions, applying analysis of variance (a = .05). Results: The presence of dry or wet conditions had no significant effect on material hardness. MTA Angelus showed significantly higher hardness values compared with NeoMTA Plus. Conclusion: The moisture of the periapical environment can compensate for the absence of a wet cotton pellet and is adequate for the setting of the materials.
