“…Both material types have the same setting reactions in common, whereby a hydration reaction of the calcium silicate is followed by a precipitation reaction of calcium phosphate [26]. Premixed, injectable sealers based on calcium silicate are hydrophilic and show good physicochemical and biological properties in vitro [28] as they are biocompatible and bioactive, features mostly attributed to the presence of calcium phosphate in their composition [29]. The target premixed calcium silicate-based sealers show results similar to or better than conventional endodontic sealers as observed in in vitro and in vivo animal studies [30,31].…”

“…As mentioned, hydrophilic calcium-silicate based root canal sealers, such as Totalfill BC Sealer (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland), can interact with the surrounding dentinal tissue by its ability to form hydroxyapatite, thereby establishing a real connection between the filling material and dentin [29]. A strong and long-lasting link between the root canal wall and the filling is one aspect of the prevention of root canal infection, caused either by regrowth of microorganisms or newly gained infection due to coronal or apical leakage [32].…”

Development of A Nano-Apatite Based Composite Sealer for Endodontic Root Canal Filling

et al. 2021

Recently, endodontic sealers based on injectable bioactive materials were proposed to improve the filling of anatomical irregularities during root canal obturation. In this context, this preliminary work investigated the possibility of realizing a new calcium phosphate-based composite sealer for root canal filling with an optimized composition on setting kinetics and dentin tubules occlusion. Several calcium phosphate/liquid phase mixtures were initially evaluated for their workability, finding two suitable formulations. Both of them contained 66 wt.% of a nano-apatite-based cement (solid powdered phase). The liquid phase (34 wt.%) comprised 13.6% propanediol and 20.4% PEG 1000 (formulation 1), and formulation 2 comprised 27.2% glycerin and 6.8% PEG 200 (formulation 2). Then, these formulations were tested by means of permeability measurements and observation by scanning electron microscopy of treated model dentin samples. Both formulations succeeded in occluding dentinal tubules: the first one was able to create a full-bodied layer on dentin surface and, moreover, to resist, at least to a large extent, against citric acid attack. The second one showed a lower effectiveness after citric acid exposure. The composite compound that better satisfied the overall required characteristics of use, workability and sealing capacity was formulation 1.

“…Endodontic obturation includes complete threedimensional filling of the dental root canal with materials that present satisfactory physical and biological properties (1)(2)(3). Ideally, the filling material should sufficiently seal the root canal and simultaneously prevent fluid penetration into the root canal space, stimulate the resolution of periapical pathologies, and encourage the deposition of cementum to obtain a biological seal (3).…”

Background and aims: AH26, Master-Dent, and Endoseal mineral trioxide aggregate (MTA) are three different types of sealers. The purpose of this study was to assess and compare THE apical seal of the root canal-treated teeth with the above-mentioned sealers in the presence and absence of moisture using the fluid filtration method. Methods: To this end, 54 freshly extracted single root canal human canines were selected for this study. The canals were prepared using rotary instruments, and then sodium hypochlorite was applied as an irrigation solution in this protocol. The specimens were randomly divided into three groups of 18. One group was obturated with the gutta-percha by the cold lateral compaction technique. Half of one of the aforementioned sealers belonged to the group of moistened teeth and the other half to the group of the dried teeth. Microleakage in all groups was assessed 3 months after the obturation of canals by the fluid filtration method. The data were analyzed using ANOVA and Tukey’s post hoc tests, and the level of significance was set at P<0.05. Results: The results showed that the minimum and maximum micro-leakage belonged to Masterdent dry (mean leakage = 1.7778 μL/ min/CmH20) and Endoseal-MTA dry (mean leakage = 3.5000 μL/min/CmH20), respectively. All three groups of sealers exhibited a significant difference in apical micro-leakage between dry and moist conditions (PMasterdent <0.001, PAH26=0.002, and PEndoseaL-MTA =0.007). Conclusion: The findings of this experimental study demonstrated that Masterdent provided the least apical micro-leakage under dry conditions while Endoseal-MTA had the highest micro-leakage under these conditions. There was a significant difference between dry and moist conditions in all groups.

“…The development of the first ready‐to‐use calcium silicate‐based sealer in 2007 (iRoot SP; Innovative BioCeramix Inc.) attracted the attention of the endodontic community, and since then, several other calcium silicate‐based sealers (CSS) have been launched. Preliminary positive perception on its use was based on the manufacturers’ claim that CSS were a successful version of MTA with handling and viscosity features optimized to fill the root canal space, considering their hydrophilic nature, bioactivity and good balance between physicochemical and biological properties (Almeida et al, 2020; Candeiro et al, 2012; Giacomino et al, 2019; Lv et al, 2017; Silva et al, 2016, 2017). In addition, most CSS are ready‐to‐use injectable pastes, which streamlines the filling procedures for dentists of all levels of skill and experience.…”

Methodological proposal for evaluation of adhesion of root canal sealers to gutta‐percha

Aim To compare the bond strength of an epoxy resin‐based sealer and two calcium silicate‐based sealers (CSS) to gutta‐percha discs using a new method. Methodology Round discs of gutta‐percha (n = 60), measuring 10 mm in diameter and 2 mm in thickness, were placed on a glass plate and a drop of each sealer (AH Plus, EndoSequence BC Sealer and EndoSeal MTA) was placed on their surface. Another identical disc was placed onto the first one and a standardized weight (0.0981 N) applied over them using a specially developed apparatus. Ten samples prepared for each sealer were submitted to a microshear bond strength test accomplished by a specially designed set‐up coupled to a universal testing machine. The Kruskal–Wallis test followed by a post hoc procedure was used to compare groups considering the preliminary analysis of the raw data had indicated the nonadherence to a Gaussian distribution (Shapiro–Wilk, p < .05). Alpha error was set at 5%. Results Overall, no premature failure occurred. All sealers had some degree of adhesiveness to gutta‐percha discs but with a significant difference amongst them (Kruskal–Wallis, p = .019). The epoxy resin‐based sealer (AH Plus) had significantly higher median shear bond strength values (1.43 MPa; 1.40–1.83) compared to EndoSeal MTA (0.53 MPa; 0.46–0.73) (p = .021) and EndoSequence BC Sealer (0.45 MPa; 0.34–0.46) (p = .023), whilst the lowest median value was observed with EndoSequence BC Sealer (0.45 MPa; 0.34–0.46) (p < .05). Conclusions CSS sealers had weaker bonding to gutta‐percha when compared to the epoxy resin‐based AH Plus sealer. The proposed methodology is an innovative and reproducible method for testing the bond strength of root canal sealers to gutta‐percha.
