“…There are no studies comparing the porosity of ProRoot MTA, Biodentine and BC Putty using Micro-CT analysis. One recent study using this methodology detected Biodentine less porous than ProRoot MTA (7). Moreover, it is important to emphasise that in the present study the Po% was still low and was not related to the formation of voids (VV%) as expected.…”

“…One result did not invalidate the other one since both studies are complementary and necessary to better understand the performance of the materials. Regarding the porosity inherent to materials, the absence of pores is closely related to the achievement of both a low solubility and a better sealing (7). In contrast, their occurrence and size can be considered an extra cause of the formation of large voids which affects the internal morphology of the material (8).…”

“…This can be achieved by reducing the marginal gaps, which are the spaces between the dentin wall and the root-end filling materials, and voids, the spaces within the filling material. Moreover, it has been reported that a better sealing is closely related to the porosity characteristics of the chosen material (7) and that the presence and size of pores can be considered a secondary cause of the formation of large voids which affects the internal morphology of the material (8).…”

This study aimed at evaluating the volume of gaps and voids, and the total porosity percentage of three calcium‐silicate‐based materials in mandibular molars apicoectomy by Micro‐CT analysis. Thirty‐three mesial roots of extracted human mandibular molars were instrumented and obturated. The apical 3mm of each root was resected and prepared. Root‐end cavities were filled with EndoSequence BC Putty (BC); ProRoot MTA (MTA) and Biodentine (BIO). Samples were scanned using a Micro‐CT scanner and the tridimensional images reconstructed. Percentage of gaps (VG%) and of voids (VV%) were obtained. Porosity percentage (Po%) was also assessed. Data were analysed using Student’s t‐test (P < 0.05). All materials presented gaps and voids. VG% was 2.006 (BC), 1.882 (MTA) and 1.450 (BIO), and VV% was 0.039 (BC), 0.021 (MTA) and 0.024 (BIO) with no statistical difference. Po% were 56.73 (BC), 51.94 (MTA) and 50.45 (BIO), with BC being statistically (P > 0.05) more porous.

“…Using micro‐computed tomography (micro‐CT), the initial total porosity of hydraulic calcium silicate sealers was reported in the range 4.5%–5.5% (Guerrero et al, 2018; Milanovic et al, 2020; Viapiana et al, 2016). Using the water sorption method, the reported porosity was around 50% compared with 3% detected in epoxy resin‐based sealers (Siboni et al, 2017).…”

Background Hydraulic materials are used in Endodontics due to their hydration characteristics namely the formation of calcium hydroxide when mixing with water and also because of their hydraulic properties. These materials are presented in various consistencies and delivery methods. They are composed primarily of tricalcium and dicalcium silicate, and also include a radiopacifier, additives and an aqueous or a non‐aqueous vehicle. Only materials whose primary reaction is with water can be classified as hydraulic. Objectives Review of the classification of hydraulic materials by Camilleri and the literature pertaining to specific uses of hydraulic cements in endodontics namely intra‐coronal, intra‐radicular and extra‐radicular. Review of the literature on the material properties linked to specific uses providing the current status of these materials after which future trends and gaps in knowledge could be identified. Methods The literature was reviewed using PUBMED, and for each clinical use, the in vitro properties such as physical, chemical, biological and antimicrobial characteristics and clinical data were extracted and evaluated. Results A large number of publications were retrieved for each clinical use and these were grouped depending on the property type being investigated. Conclusions The hydraulic cements have made a difference in clinical outcomes. The main shortcoming is the poor testing methodologies employed which provide very limited information and also inhibits adequate clinical translation. Furthermore, the clinical protocols need to be updated to enable the materials to be employed effectively.

Recently, a paste-type premixed calcium silicate-based mineral trioxide aggregate (MTA) product that quickly solidifies through a pozzolanic reaction was introduced to replace existing MTA, which has the disadvantage of a long setting time. In this study, we evaluated the effect of moisture content in the root canal on the setting time of premixed calcium silicate-based MTA in a simulated root canal environment using Endoseal MTA and Well-Root ST, among commercially available products. The setting time was measured according to ISO 6876/2012. A mold made using grades 2, 3, and 4 dental gypsum according to the classification of ISO 6873/2013 was used to reproduce the difference in moisture environment. Differences in moisture content were measured using micro-computed X-ray tomography (micro-CT). The micro-CT results showed that the moisture content was the highest and lowest in the grade 2 and 4 gypsum molds, respectively. Moreover, the setting time indicated by the manufacturer was the shortest for the grade 2 gypsum mold. Hence, the differences in moisture content significantly affect the setting time of MTA. This result can help set future experimental conditions and develop premixed calcium silicate-based MTA products.
