“…For characterization of the bioactivity potential of materials, several methods have been used to identify crystalline deposits on the material surface and dentine interface (Oliveira et al 2013, Niu et al 2014, Kim et al 2015. The morphological aspects can be observed with SEM and lCT analysis, with high-quality visualization of the material surface and dentine interface (Kim et al 2015, Viapiana et al 2016).

do Carmo SS, N espoli FFP, Bachmann L, Miranda CES, Castro-Raucci LMS, Oliveira IR, Raucci-Neto W. Influence of early mineral deposits of silicate-and aluminate-based cements on push-out bond strength to root dentine. International Endodontic Journal, 51, 92-101, 2018. Aim To evaluate mineral trioxide aggregate (MTA), Biodentine and several formulations of calcium aluminate cements (CACb) in terms of their ability to release calcium ions (Ca 2+ ) and form apatite-like precipitates after short-term immersion in phosphate-buffered saline (PBS) and its influence on the bond strength to the root-end cavity. Methodology Ten samples of MTA, Biodentine, CACb and calcium-enriched aluminate cement (CACb+) were placed in contact with PBS or deionized water for 14 days. The cement surfaces were analysed using SEM, EDS-X and FTIR. Eighty standardized root-end cavities filled with the cements (ten samples of each cement) were immersed in PBS or deionized water for 14 days, and the bond strengths were measured. Data from the push-out test were analysed using two-way ANOVA and Tukey's tests (a = 0.05).Results A gradual decrease was observed in Ca 2+ concentrations and pH of all solutions. FTIR bands of different phases of hydroxyapatite were identified. Crystalline formation was observed on the surface of all cements after immersion in PBS. No significant difference was observed in the bond strength of the test materials (P > 0.05); however, all cements without contact with the solution revealed significantly lower bond strength values than those in contact with the solution (P < 0.05). Conclusion MTA, Biodentine, CACb e CACb+ were associated with precipitation of crystals after being in contact with PBS for 14 days, indicated by different phases of hydroxyapatite crystalline formation, which also increased dislodgment resistance of the material from root-end cavities. The CACb+ had similar bond strengths and precipitation of crystals to existing materials.

“…BioRoot RCS compared to contemporary root canal sealers (AHPlus, Acroseal, EndoRez, RealSeal SE, Hybrid Root SEAL, RootSP, and MTA Fillapex) has the lower cytotoxicity and genotoxicity [24]. The sealing properties of BioRoot RCS combined with gutta-percha are comparable to those of AHPlus, but microCT has revealed a higher void volume for BioRoot RCS than resin-based sealer, possibly due to the shorter working time and less flow than AHPlus [28]. …”

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.
