“…Paste B includes silicon dioxide, titanium dioxide, and base resin (pentaerythritol, rosinate, and toluene sulphonamide), and 13.2% set MTA particles as filler. The working time is 23 min, with a complete set time of approximately 2 h. Several properties of this root canal sealer, such as flow and viscosity [10, 11], dimensional change [11], material porosity [12, 13], sealing ability [11], radiopacity, electrical conductivity [14], antibacterial effect [15], biocompatibility [16–20], cytotoxicity [19, 21–23], and genotoxicity [24, 25], have been investigated.…”

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufacturers' instructions. Twelve cylindrical molds (inner diameter 4 mm; height 3 mm) were placed on a glass petri dish and packed with the materials. The dish was transferred to an incubator. After 72 h the molds were examined by scanning electron microscopy and energy dispersive X-ray microanalysis. Results. BioRoot RCS and Well-Root ST had high peaks of calcium, zirconium, oxygen, carbon, silicon, and chlorine. Well-Root ST also had sodium, magnesium, aluminum, and titanium peaks. MTA Fillapex and AHPlus had carbon, oxygen, calcium, titanium, and bismuth peaks. A silicon peak was also observed for MTA Fillapex, and zirconium and tungsten peaks for AHPlus. Conclusion. BioRoot RSC had the highest degree of purity. The clinical implication of metals contained in the other sealers needs to be investigated.

“…In endodontic therapy, obturation aims to avoid the recontamination of the already cleaned canal by filling with gutta-percha points and endodontic sealer [4,7,[16][17][18]25]. The endodontic sealers have many functions during the obturation of the root canal system: lubrication and aid in point seating, union among the gutta-percha points and the root canal walls, and filling of empty spaces not completed by the main material.…”

Introduction: The sealers were developed for filling of root canals. Due to their physicochemical and technical properties used for obturation, often, extrusion is observed through apical constriction and occasionally by lateral and secondary canals. Objective: To review the literature on important properties to be considered in AH Plus sealer extrusion and report a case series of this sealer extrusion. Literature review: Articles evaluating the cytotoxicity and biocompatibility properties, besides flow and solubility were selected. Case report: In the presented cases, endodontic treatment was performed with rotary instrumentation and irrigation with 2.5% NaOCl. Obturation employed visual, tactile, and radiographic proof of gutta-percha main cone, and different obturation techniques. There were no reports of pain during and after endodontic treatment. Conclusion: AH Plus has adequate properties for a filling material and causes no major damage to the periapical tissues due to its little cytotoxic.

Evaluation of the biological and physicochemical properties of calcium silicate‐based and epoxy resin‐based root canal sealers

Biocompatibility, dimensional stability, radiopacity, flow, and low solubility are the characteristics of an ideal endodontic sealer. This study evaluated and compared in vivo and in vitro biological and physicochemical properties of calcium silicate‐based sealers: Sealer Plus BC (BC), MTA Fillapex (MF); and resin‐based sealers: AH Plus (AHP) and Sealer Plus (SP). Apical papilla cells were exposed to sealer extracts and subjected to MTT, SRB, scratch, alkaline phosphatase enzyme activity (ALP) and Alizarin red staining (ALZ) assays. Sealers were histologically evaluated in connective tissue of Wistar rats in different periods. Radiopacity, film thickness, flow, setting time, pH and element analyses were investigated. BC had better results compared to AHP and MF at hour 72 for MTT assay (p < .05), and the highest cell viability under SRB (p < .05). All sealers presented ALP activity. BC presented the highest mineralized deposition under ALZ (p < .05). BC and MF promoted wound healing. All sealers induced an initial inflammation reaction that decreased over time. Eosinophils were observed at day 7 in MF (p < .05). Despite MF did not present final setting time, the sealers properties were in accordance to ISO 6876/2012 and ASTM C266‐08. All sealers presented cell viability and biocompatibility. BC presented higher pH values and bioactivity. The materials tested showed physico‐chemical properties in accordance with standards, except for MF setting time.
