“…The results of the study revealed significantly low bond strength results of Endoseal MTA sealer in both subgroups IB and IIB, these lower records can be due to calcium and hydroxyl ions releasing during inherent setting property, this ions form appetite by MTA when coming in contact to phosphate containing moisture, then deposited in collagen network promoting mineral nucleation forming micro-tags that have low adhesion quality (34) . The study results were in accordance with other studies demonstrated that calcium silicate-based sealers represented weak bond strength to radicular dentin when compared to AH Plus which showed significantly higher bond strength, also recent systematic review and meta-analysis told that bioceramic sealers do not perform superior than epoxy resin sealers with dislodgement resistance test (23,28,29,34,35) .…”

Purpose: The present study was performed to evaluate the bond strength of EndoSeal MTA and AH Plus after using EDTA or apple vinegar as final irrigant. Materials and Methods: Sixty extracted human single rooted teeth were decapitated, instrumented using Universal ProTaper rotary system up to size F4 and divided randomly into two main groups (n=30) according to the solution used as final irrigation; Group I: irrigated with 17% EDTA and Group II : 5 % Apple vinegar, then distributed according to sealer used in obturation with gutta-percha into four subgroups (n=15); subgroup IA (EDTA + AH Plus), subgroup I B (EDTA +Endoseal MTA), subgroup IIA (apple vinegar + AH Plus), and subgroup IIB (apple vinegar + Endoseal MTA). After obturation and incubation in 100% humidity at 37°C for one week. All roots were embedded in self cure acrylic resin and sectioned horizontally into slices of 2 mm thickness, the push-out test was applied using universal testing machine, bond strength (MPa) calculated and the data were tabulated and statistically analyzed. Results: AH Plus represented the highest bond strength after using EDTA or apple vinegar compared with Endoseal MTA, EDTA showed superior results with both types of sealer compared to apple vinegar, and the middle part of the root canal showed the highest bond strength (P<0.05) Conclusion: EDTA final irrigating solution reported higher values of the bond strength compared to apple vinegar with both AH Plus and Endoseal MTA, and AH Plus reported highest push-out bond strength with both irrigating solutions.

“…Previous studies have suggested that after drying the canal with PP, the remaining moisture from the dentinal tubules can maintain the hardening properties of bioceramic sealers of other commercial brands. 9,12,21 The present results corroborate these findings because the overall bond strength was higher for the PP drying protocol.…”

“…18 This study showed that the bond strengths of both brands were within the range reported in the literature for bioceramic sealers. 9,18,[20][21][22] It should be noted that laboratory tests are not capable of predicting the clinical behavior of materials; since teeth are located in the alveolus, many other factors, like the periodontal ligament and the temperature of the oral cavity, can influence the properties of an endodontic sealer. However, push-out tests are useful for comparing the bond strength and evaluating the failure patterns of different materials or techniques under controlled settings, thereby minimizing bias.…”

Effect of Different Root Canal Drying Protocols on the Bond Strength of Two Bioceramic Sealers

et al. 2022

Summary Objectives This study evaluated in vitro the effect of two different drying protocols on the dentin bond strength of two different bioceramic sealers (Sealer Plus BC [SP] and Bio C Sealer [BCS]). Bond strength and failure mode were evaluated according to the sealer, drying protocol, and root canal third. Materials and Methods Sixty extracted human mandibular single-rooted premolars were selected after anatomical standardization. The crowns were sectioned and root canals were prepared. Roots were randomly divided into four groups (n = 15 each). Each group was assigned a combination of one of the evaluated sealers (SP or BCS) and one of the drying protocols: canals dried with paper points (PP) or irrigation with saline followed by aspiration with silicon cannulas (IA). Obturations were performed using a single-cone technique. The teeth were temporized and stored for 7 days (100% humidity, 37°C). Roots were cut to obtain 2 mm thick discs for each third (coronal, middle, and apical). Push-out tests were performed on a universal testing machine, and the bond strength (MPa) of each specimen was calculated by dividing the load (N) by the interface area. Failure type was assessed under ×4 magnification. Statistical Analysis Data were statistically analyzed with a significance set at 5%. An analysis of variance test followed by the Games-Howell post-hoc test was used to compare the mean values between the groups and the interaction of the variables. Results The predominant failure type was cohesive, followed by mixed failure and adhesive in all groups. The apical third presented the highest bond strength (p < 0.05) regardless of the group, followed by the middle and coronal thirds. Overall, the SP PP group had the highest mean bond strength (p < 0.01), but the SP sealer was negatively affected by the IA drying protocol in the coronal and middle thirds. The BCS presented similar results within the third stage, regardless of the drying protocol. Conclusions Sealer Plus BC had a higher bond strength than Bio C Sealer, but it was negatively affected by the irrigation-aspiration protocol in the coronal and middle thirds. For the apical third, there was no difference between the groups; thus, a similar bond strength was observed regardless of the drying protocol or sealer.

“…Tricalcium silicate-based sealers have higher flowability than resin-based sealers due to the smaller size of particles, and can therefore bond to the smear layer and penetrate into dentinal tubules. 28 This finding can explain no significant reduction in the PBS of Endoseal TCS following plasma therapy in the present study.…”

Introduction: The current study aimed to assess the effect of non-thermal plasma (NTP) on the pushout bond strength (PBS) of epoxy resin and tricalcium silicate-based endodontic sealers. Methods: Forty single-canal extracted teeth were decoronated at the coronal region, underwent root canal preparation, and were assigned to four groups (n=10) for the application of AH26 sealer, NTP+AH26 (P-AH26), Endoseal TCS sealer, and NTP+Endoseal TCS sealer (P-TCS). The root canals were sectioned into 1 mm slices, and the PBS value was measured in a universal testing machine. Data were analyzed by the Friedman, Kruskal-Wallis, and Dunn tests (P<0.05). Results: The PBS of TCS and P-TCS groups was not significantly different (P>0.05). The PBS of the P-AH26 group was significantly lower than that of the AH26 group in the middle third (P<0.05). The PBS of the AH26 group was higher than the other groups in all sections. The PBS in the apical third was lower than other sections in all groups (P<0.05). Conclusion: NTP had no significant effect on the PBS of Endoseal TCS. NTP significantly decreased the PBS of AH26 sealer in the middle third but had no significant effect on its bond strength in other sections.
