“…The first results of this study showed that all tested root‐end filling materials presented gaps and voids, which are in line with previous studies (Iglecias et al, 2017; Jung et al, 2020; Kim et al, 2018; Toia, Teixeira, Cucco, Valera, & Cavalcanti, 2020). Moreover, White MTA, MTA Repair HP, and Bio‐C Repair present similar results in the percentual volume of gaps after root‐end cavity filling ( p > .05).…”

A root‐end filling material is required to fill the root‐end cavity without gaps or voids, to prevent root canal reinfection and to provide periapical healing. Thus, this study evaluated the volume of marginal gaps and voids of three root‐end filling materials using microcomputed tomography (micro‐CT). Thirty maxillary incisors were prepared and filled with gutta‐percha and endodontic sealer. The specimens were scanned using micro‐CT and distributed into three groups (n = 10): White MTA, MTA Repair HP, and Bio‐C Repair. The root tips were resected at 90° to the longitudinal axis and the cavity (3 mm depth) was prepared with an ultrasonic tip. The materials were handled, and the cavities were filled. The specimens were rescanned and the percentual volume of gaps and voids were analyzed. The data were analyzed using Kruskal–Wallis and Dunn tests (p < .05). No statistical difference was found in the percentage of gaps among the tested materials (p > .05). White MTA presented less voids than Bio‐C and MTA Repair HP (p < .05). The materials presented a similar percentual volume of gaps and White MTA presented less voids than other tested materials.

“…This could be explained by the consistency in which the material is packaged and commercialized. The premixed consistency could cause less control over defects that may persist in the mass of the material, as suggested by Toia et al [51] Increasing the thickness of PMTA did not result in a significant improvement of its POBS values. However, it did affect the predictability of this material as the m parameter was higher at 3 mm (3.09) than at 5 mm (2.28).…”

Background The aim of this study was to compare the pushout bond strength (POBS) of three hydraulic cements, when used at thicknesses of 3 and 5 mm. Methods 78 root slices of 3 and 5 mm of thickness were obtained from human teeth. Cylindrical cavities of 1.4 mm of diameter were drilled and filled with Biodentine (BD), Totalfill Root Repair paste (TF) or ProRoot MTA White (PMTA). Pushout tests were performed 21 days later. The fracture pattern of each sample was also analyzed. POBS data were analyzed with Welch and Brown-Forsythe and Tamhane’s post hoc tests and a Weibull analysis was also performed. Results In the 3 mm group, TF showed significantly lower bond strength than BD and PMTA. In the 5 mm group, BD showed significantly higher bond strength than TF. Both BD and TF showed higher bond strength when the thickness of the sample increased, while PMTA did not. Conclusions TF and BD achieve higher pushout bond strength resistance when used at a thickness of 5 mm than at 3 mm, while the mean resistance of PMTA is less influenced by the thickness. At 5 mm of thickness, BD and PMTA exhibit similar resistance to displacement. However, the behavior of BD is more predictable than that of its predecessor. BD is a reliable hydraulic cement for clinical situations where thick cavities need to be filled and displacement resistance plays an important role. Clinicians need to consider choosing specific hydraulic cements according to the thickness of material to be used.

“…Calcium silicate based root-end filling materials have gained tremendous popularity over the past decade and are routinely used in endodontics for various purposes including root-end fillings during surgical procedures. Previous studies have evaluated various physical properties of these materials including biocompatibility, sealing ability, and marginal adaptability [ 19 20 21 ]. BC-RRM is available in 2 forms, the paste and the putty.…”

Objectives Endosequence Bioceramic Root Repair Material (BC-RRM) is used in endodontic microsurgery. It is available as a paste and a putty. However, no studies to date have examined the sealing ability of these forms alone or in combination as root-end filling materials. Hence, this study aimed to compare the sealing properties of these 2 forms of BC-RRM. Materials and Methods Forty-two extracted upper anterior teeth were divided into 3 experimental groups, a positive and negative control. After the root canal treatment, the root ends were resected, retroprepared and retrofilled with either putty, paste + putty or mineral trioxide aggregate (MTA). The teeth were mounted in tubes so the apical 3 mm was submerged in Brain Heart Infusion (BHI) broth. The coronal portions of the canals were inoculated with Enterococcus faecalis and BHI broth and incubated for 30 days. The broth in the tubes was analyzed for colony forming units to check for leakage of bacteria from the canal. The teeth from the groups were sectioned and analyzed using scanning electron microscopy (SEM). The Kruskal-Wallis test and analysis of variance were used to analyze the data with a significance level p < 0.05. Results The BC-RRM and MTA groups showed similar sealing ability. The positive control showed leakage in all samples. The SEM imaging showed the presence of bacteria in all experimental groups at the material-tooth interface. Conclusions No significant differences were noted in the experimental groups, providing sufficient evidence that any combination could be effectively used during endodontic microsurgery.
