Root Canal Sealers

Calcium silicate-based bioactive glass has received significant attention for use in various biomedical applications due to its excellent bioactivity and biocompatibility. However, the bioactivity of calcium silicate nanoparticle-incorporated bioactive dental sealer is not much explored. Herein, three commercially available bioactive root canal sealers (Endoseal MTA (EDS), Well-Root ST (WST), and Nishika Canal Sealer BG (NBG)) were compared with a resin-based control sealer (AH Plus (AHP)) in terms of physical, chemical, and biological properties. EDS and NBG showed 200 to 400 nm and 100 to 200 nm nanoparticle incorporation in the SEM image, respectively, and WST and NBG showed mineral deposition in Hank’s balanced salt solution after 28 days. The flowability and film thickness of all products met the ISO 3107 standard. Water contact angle, linear dimensional changes, and calcium and silicate ion release were significantly different among groups. All bioactive root canal sealers released calcium ions, while NBG released ~10 times more silicon ions than the other bioactive root canal sealers. Under the cytocompatible extraction range, NBG showed prominent cytocompatibility, osteogenecity, and angiogenecity compared to other sealers in vitro. These results indicate that calcium silicate nanoparticle incorporation in dental sealers could be a potential strategy for dental periapical tissue regeneration.

ABSTRACTIntroduction: The aim of this in vitro study was to assess the pH values of selected calcium-silicate root canal sealers in comparison with AH Plus resin-based root canal sealer.Materials and methods: Six root canal sealers were included in this study: BioRoot RCS (Septodont, France), GuttaFlow bioseal (Coltėne/Whaledent, Switzerland), MTA Fillapex (Angelus, Brazil), Total Fill BC Sealer (FKG, Switzerland), Well-Root ST (Vericom, Korea) and AH Plus (Dentsply, DeTrey, Germany). Materials samples (n = 6) were placed in dishes and immersed in 10 mL of distilled water (pH = 6.8). After 1, 3, 24, 48, 72, 168, 336 and 504 hrs, water pH was determined with a pH meter calibrated with a solution of known pH. Data were statistically analyzed using Student-t test (p < 0.05).Results: There were differences in the water pH between the materials tested. The highest water pHs were exhibited by Total Fill BC Sealer, Well-Root ST and BioRoot RCS (pH ~12), followed by GuttaFlow bioseal (pH ~10.5) and MTA Fillapex (pH ~9). The lowest pH was shown by AH Plus (pH ~8).Conclusions: All calcium-silicate root canal sealers studied are able to elevate the pH level, which could have biological and antimicrobial effects. The AH Plus root canal sealer has poor alkalizing properties.

Introduction: International standards require adequate radiopacity of root canal filling materials to distinguish them from natural structures, such as tooth tissues, and to allow evaluation of the quality of the root canal filling.The aim of this in vitro study was to assess the radiopacity of selected calcium-silicate root canal sealers compared with the resin-based AH Plus root canal sealer.Materials and methods: The study included 6 root canal sealers: BioRoot RCS, GuttaFlow bioseal, MTA Fillapex, Total Fill BC Sealer, Well-Root ST and AH Plus. Six disc-shaped samples were prepared from all analysed materials (4 mm in diameter and 1 mm thick) and analysed using a digital radiography technique and aluminium step wedges (1.5–15 mm thick) as a standard reference. The radiopacity was determined using computer image analysis. The data was statistically analysed using a Tukey’s range test.Results: All root canal sealers showed radiopacity at least corresponding to the 3 mm aluminium step wedge. AH Plus (13.23 mm Al) showed the highest radiopacity, followed by Total Fill BC Sealer (7.93 mm Al), Well-Root ST (7.12 mm Al), BioRoot RCS (5.93 mm Al) and GuttaFlow bioseal (5.08 mm Al ). MTA Fillapex (3.02 mm Al) showed the lowest radiopacity.Conclusions: Although the evaluated root canal sealers show different radiopacities, all the materials met the criteria laid down by the International Organization of Standardization.

Root Canal Sealers

Over the last two decades, calcium silicate-based materials have grown in popularity. As root canal sealers, these formulations have been extensively investigated and compared with conventional sealers, such as zinc oxide–eugenol and epoxy resin-based sealers, in in vitro studies that showed their promising properties, especially their biocompatibility, antimicrobial properties, and certain bioactivity. However, the consequence of their higher solubility is a matter of debate and still needs to be clarified, because it may affect their long-term sealing ability. Unlike conventional sealers, those sealers are hydraulic, and their setting is conditioned by the presence of humidity. Current evidence reveals that the properties of calcium silicate-based sealers vary depending on their formulation. To date, only a few short-term investigations addressed the clinical outcome of calcium silicate-based root canal sealers. Their use has been showed to be mainly based on practitioners’ clinical habits rather than manufacturers’ recommendations or available evidence. However, their particular behavior implies modifications of the clinical protocol used for conventional sealers. This narrative review aimed to discuss the properties of calcium silicate-based sealers and their clinical implications, and to propose rational indications for these sealers based on the current knowledge.
