“…Calcium silicate materials produce an alkaline pH, due to the release of calcium ions (28), and the repair mechanism of mineralized tissue depends on the pH and Ca²+ release capacity of the material (29). All the materials evaluated had high values of pH, in agreement with previous studies (14,18,25). Table 3.…”

“…Endosequence BC (Brasseler USA, Savannah, GA) and TotalFill BC (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland) are premixed, ready-to-use calcium silicate materials (14) including a putty, indicated as root repair material and a sealer to root canal obturation (15). BC Sealer hydrate by contact with environmental moisture (15), and presents an alkaline pH, flow, film thickness and radiopacity according to ISO 6876 (16)(17)(18).…”

Differences in liquid-to-powder ratio can affect the properties of calcium silicate-based materials. This study assessed the influence of powder-to-gel ratio on physicochemical properties of NeoMTA Plus. Setting time (minutes), flow (mm and mm²), pH (at different periods), radiopacity (mm Al) and solubility (% mass loss) were evaluated using the consistencies for root repair material (NMTAP-RP; 3 scoops of powder to 2 drops of gel) and root canal sealer (NMTAP-SE; 3 scoops of powder to 3 drops of gel), in comparison to Biodentine cement (BIO) and TotalFill BC sealer (TFBC). Statistical analysis was performed using one-way ANOVA and Tukey tests (α=0.05). BIO had the shortest setting time, followed by NMTAP-RP and NMTAP-SE. TFBC showed the highest setting time and radiopacity. BIO, NMTAP-RP, and NMTAP-SE had similar radiopacity. All materials promoted an alkaline pH. NMTAP-RP/SE presented lower solubility than BIO and TFBC. Regarding the flow, TFBC had the highest values, followed by NMTAP-SE, and NMTAP-RP. BIO had the lowest flow. In conclusion, NMTAP in both powder-to-gel ratios showed high pH and low solubility. The increase in the powder ratio decreased the setting time and flow. These findings are important regarding the proper consistency and work time to clinical application.

“…The appropriate filling of the main root canal for both systems could also be related to the high flow of Bio-C Sealer [ 4 ], since this is an important characteristic to seal spaces between gutta-percha cone and dentinal wall [ 15 ]. Moreover, the flow property of root canal sealers determines how effectively accessory canals will be obturated, influencing in the presence of the voids [ 16 ].…”

“…Novel calcium silicate sealers are presented in a premixed-syringe with an intracanal tip designed to be used with a single-cone obturation technique [ 1 ]. Among these new materials, Bio-C Sealer (Angelus, PR, Brazil) showed short setting time, alkalinization capacity, proper flow and radiopacity, besides cytocompatibility [ 4 5 ]. However, there is no study evaluating the filling ability of this sealer.…”

Objectives This study evaluated by using micro-computed tomography (micro-CT) the filling ability and sealer apical extrusion promoted by a new Sealer Injection System (SIS; Angelus) with side openings needle, in comparison with the conventional injection system, associated with a new ready-to-use calcium silicate-based sealer (Bio-C Sealer). Materials and Methods Acrylic resin models containing a main curved artificial canal and 3 simulated lateral canals in apical, middle and cervical thirds were used. The main root canals were prepared using a rotary system up to size 35.05. The canals were filled with Bio-C sealer by using a single cone technique and the conventional delivery system or SIS. Samples were scanned in micro-CT. The percentage of voids throughout the entire extension of the main root canal and in each third of the lateral canals, besides the apical extrusion of the sealer was calculated. Data were submitted to t -test ( p < 0.05). Results There was no difference between both systems in the main root canals filling. Although the volume percentage of voids was similar in the apical and middle thirds of lateral canals, SIS had the greatest filling ability of the cervical third lateral canal. Moreover, the conventional system showed the highest apical extrusion of the sealer. Conclusions The conventional and SIS obturation systems had an appropriate filling ability of the main root canal. SIS had the best filling of the cervical third of the lateral canals, besides lower sealer apical extrusion, suggesting its clinical indication.

“…Given that achieving proper root canal filling is important for the long-term success of endodontically treated teeth, root canal sealers must have appropriate physical and chemical properties [14]. Zordan-Bronzel et al [15] evaluated the physicochemical properties of the new Bio-C Sealer in comparison with the TotalFill BC calcium silicate-based sealer and the AH Plus epoxy resin-based sealer using conventional and micro-computed tomography (CT) tests. They concluded that the Bio-C Sealer has a short setting time, alkalinization ability, and adequate flow and radiopacity.…”

Biocompatibility of a High-Plasticity, Calcium Silicate-Based, Ready-to-Use Material

et al. 2020

The Bio-C Sealer is a recently developed high-plasticity, calcium-silicate-based, ready-to-use material. In the present study, chemical elements of the materials were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The biocompatibility of the Bio-C Sealer was investigated using cytotoxicity tests and histological responses in the roots of dogs’ teeth. XRD, SEM, and FTIR produced hydrated calcium silicate in the presence of water molecules. In addition, FTIR showed the formation of calcium hydroxide and polyethylene glycol, a dispersing agent. The 1:4 dilutions of Bio-C Sealer presented weaker cytotoxicity than the Calcipex II in an in vitro system using the V-79 cell line. After 90 d, the periradicular tissue response of beagle dog roots was histologically evaluated. Absence of periradicular inflammation was reported in 17 of the 18 roots assessed with the Bio-C Sealer, whereas mature vertical periodontal ligament fibers were observed in the apical root ends filled with the Bio-C Sealer. Based on these results and previous investigations, the Bio-C Sealer is recommended as an effective root-end filling material. These results are relevant for clinicians considering the use of Bio-C Sealer for treating their patients.
