“…The mechanism of bonding of hydraulic calcium silicate sealer to root dentin could be linked to the following mechanisms; infiltration of the sealer's mineral content into the intratubular dentin resulting in the establishment of a mineral infiltration zone produced after denaturing the collagen fibers with a strong alkaline sealer, Partial reaction of calcium silicate hydrogel with phosphate in a moistened environment leading to the formation of hydroxyapatite with the dentin substrate, and Diffusion of the sealer particles into the dentinal tubules to produce mechanical interlocking bonds added to the chemical bond (Mathew et al, 2019) The results of this study coincide with other studies that found no significant difference between pre-mixed TotallFill biocermic sealer (FKG, Switzerland) and AH Plus resin sealer (DENTSPLY, USA) as both sealers exhibited similar bonding strength to the root canal (Gyulbenkiyan et al, 2020). Also, other studies came up with the same conclusion while investigating the premixed TotallFill, relating their results to the small size particle, followability and expansion of the premixed bioceramic sealer allowing it to penetrate into the dentinal tubules while AH Plus sealer is mild acidic pH which could etch dentin slightly, thereby improving sealer dentin adaptation (Salem et al, 2019). Similarly, Abdelrahman et al rendered the non-significant outcome to the alkaline nature of the calcium silicate-based sealers properties, low film thickness, dimensional stability and denaturation of the dentin collagen which could collectively facilitate the sealer penetration and adaptation to root canal dentin (Abdelrahman & Hassan, 2021).…”

Introduction: This study compared in vitro the coronal sealing ability of four types of endodontic sealers One-Fil, ADSEAL, GuttaFlow Bioseal, BioRoot RCS Materials and Methods: Thirty-two single-rooted mandibular premolars were randomly divided into 4 groups (n=8). After Instrumentation, each group obturated using a different type of sealer as group 1: One-Fil, group 2 ADSEAL, group 3: GuttaFlow Bioseal, and group 4: BioRoot RCS. Teeth were cleared then subjected to a dye penetration test, then evaluated under stereomicroscope.Results: Kruskal-Wallis test was used to compare dye penetration depth among the different endodontic sealers. Post-hoc analysis was conducted using Dunn's multiple comparison test. The mean score of dye penetration could be arranged from the least to the greatest as follows: One-Fil (1.38 ± 0.52) followed by ADSEAL (2.38 ± 0.52) without significant difference between them, however One-Fil recorded lower significant dye penetration compared to GuttaFlow Bioseal (2.5 ± 0.53) and BioRoot RCS which showed the highest mean of dye penetration (2.75 ± 0.46). Conclusions:Premixed calcium silicate sealer revealed the highest significant resistance against dye penetration while hand mixed calcium silicate sealer revealed the least resistance against coronal dye penetration.Clinical Relevance: All types of the investigated sealers allowed dye penetration with variable degrees, therefore, proper coronal and apical sealing with adequate final restoration is the key to successful treatment outcome.

“…This solution was then centrifuged for 7 minutes at 4000 rpm to separate the debris from the dye that had been eliminated. 25 Each sample's supernatant layer was transferred in quantities of 2 mL to plastic cuvettes. Then, using concentrated nitric acid as the blank, samples were read their optical density using an automated spectrophotometer (Shimadzu Europe -UV-1650PC, Germany).…”

Background: It has been established that several filling techniques can affect apical leakage, which is responsible for 59% of endodontic failures. The primary goal of endodontic therapy is to create a tight seal that aids in repairing the periapical tissues, prevents apical periodontitis, and shields against root canal infection. The study aims to compare the apical sealing ability of epoxy resin based sealer (AH plus), which is an epoxy-resin-based root canal sealer, GuttaFlow 2, which is a silicone-based root canal sealer, GuttaFlow bioseal is a bioactive glass-based root canal sealer, TotalFill HiFlow bioceramic (BC) sealer is a silicate-based root canal sealer (bioceramic sealer) using a single cone technique by spectrophotometric analysis. Methods: This study chose 64 maxillary first molars with a straight palatal root. Following palatal roots sectioning to 11 mm from the root apex, the canals were instrumented up to size X4 using Protaper Next. They were separated into four experimental groups (n = 15) per each group based on the kind of sealer utilized, Group I: AH plus, Group II: GuttaFlow 2, Group III: GuttaFlow bioseal, Group IV: TotalFill BC HiFlow, and two control groups (n =2 for each). After completing obturation, the dye extraction technique was used to evaluate apical leakage. A spectrophotometer was used to measure the optical density of the solution after all the dyes were liberated from the interfacial regions. Result: A statistically non-significant difference between the investigated root canal sealers in apical microleakage P > 0.05 was noted. The highest mean values were observed in group IV (0.08046), group I(0.07731), and group II(0.06209), while the lowest mean value in group III (0.05719) Conclusions: All types of sealers used in this investigation showed various amounts of microleakage. None of the sealants could completely close the apical foramen to provide a fluid-tight seal.
