“…These results were in accordance with previous studies (19,20) which concluded that the premixed BC group had better sealing ability than the MTA group . Moreover these results were in agreement with previous studies (8,21) which evaluated the sealing ability of MICRO-MEGA MTA, Endosequence BC, and Biodentine as furcation repair materials using a dye extraction leakage method and concluded that the Endosequence BC showed the better sealing ability when compared with other root repair materials, this was due to the particle size, which allowed the premixed BC material to penetrate into the dentinal tubules and bond to the adjacent dentin easily. They also stated that the probable causes for more microleakage of MTA compared to Wellroot premixed due to the long setting time of MTA ,difficult handling of the material and the presence of voids (8) .…”

“…Recently, premixed BC materials have become available on the market in different forms with the same chemical structure. Premixed BCs are highly alkaline (pH = 12.7), so they offer sustained calcium release and ensure their antibacterial activity (8) . Premixed BCs possess the capability of inducing hydroxyapatite formation, indicating their tissue-inductive features (9) .…”

Purpose:The aim of this in vitro study was to evaluate the microleakage of premixed BioCeramics (BCs) and mineral trioxide aggregate (MTA) for sealing primary molar furcal perforations. Materials and Methods: This study was carried out on 30 extracted mandibular primary molars. Perforations of the furcation areas were created in the pulp chamber floor of the teeth. The molars were then divided randomly in two groups (n=15). Perforations were then repaired with biocompatible materials. After 72 h, the teeth were immersed in 2% basic fuchsine dye solution for 24h. The teeth were then sectioned longitudinally and evaluated for dye leakage. Data analyzed statistically using ANOVA test. Results: There was a statistically significant difference between the micro leakage of MTA (1669.25±140.59 µm) and premixed Bioceramics(1275.21±235.998 µm) groups (P>0.008). Conclusion: Premixed Bioceramics appeared to have superior sealing ability than MTA in perforation repair in primary teeth.An ideal sealing material should be biocompatible, non-toxic, bactericidal or bacteriostatic, radiopaque, non-absorbent, and maintain a good seal. Moreover, it should possess the ability to induce osteogenesis Codex : 01/22.04

“…The management of root perforation is a time-dependent procedure, where hermetic physical seal is crucial to improve the prognosis and survival of the affected tooth [ 32 ]. It has been reported that up to 52–79% of the root canal may remain unprepared, regardless of the instruments or instrumentation technique used [ 33 ], and no currently available irrigation protocol is capable of completely disinfecting the entire root canal system [ 34 ].…”

“…Techniques and materials applied for root perforation repair have not been standardized. However, MTA is generally assumed to be a benchmark for sealing various types of root perforations [ 32 ]. MF is one of the newest MTA-based repair materials, which surpasses traditional MTA in terms of clinical applicability due to its superior handling and delivery characteristics as well as faster setting time and thus increased washout resistance [ 10 , 19 ].…”

The present study evaluated the effect of ultrasonic agitation on the porosity distribution of BioRoot RCS/single gutta-percha cone (BR/SC) and MTA Flow (MF) root canals fillings used as apical plugs in moderately curved and apically perforated roots. Eighty mesial root canals of mandibular first molars were enlarged up to ProTaper NEXT X5 rotary instrument 2 mm beyond the apical foramen, simulating apical perforations. Specimens were randomly divided into four experimental groups (20 canals per group) according to the material and technique used for root canal obturation: BR/SC, BR/SC with ultrasonic agitation (BR/SC-UA), MF and MF with ultrasonic agitation (MF-UA). The ultrasonic tip was passively inserted into the root canal after the injection of flowable cement and activated for 10 s. The specimens were scanned before and after obturation with a high-resolution micro-computed tomography scanner, and the porosity of the apical plugs was assessed. The differences between groups were analyzed using the Kruskal-Wallis and Mann-Whitney tests, with the significance level set at 5%. None of the obturation materials and techniques used in this study was able to provide a pore-free root canal filling in the apical 5 mm. Considerably higher percentages of open and closed pores were observed in the MF and MF-UA groups, with the highest porosity being in the MF-UA group (p < 0.05). No significant differences were observed between the BR/SC and BR/SC-UA groups, where the quantity of open and closed pores remained similar (p > 0.05).

“…A limitation of the current study is that the use of an in vitro model may not completely recapitulate the exact clinical situation. Several recent studies from 2019-2021 [52][53][54] attempted to compare the sealing ability of different bioceramic materials, but these used dye extraction [52,53] or protein leakage [54] models without any added bacterial contamination. Further in vivo studies will be needed to assess the antibacterial activity of various calcium silicate-based materials in more detail.…”

Bacterial Colonization and Proliferation in Furcal Perforations Repaired by Different Materials: A Confocal Laser Scanning Microscopy Study

et al. 2021

Following furcal perforation, bacteria may colonize the defect and cause inflammation and periodontal destruction. This study used confocal laser scanning microscopy (CLSM) to evaluate Enterococcus faecalis colonization and proliferation in furcal perforations repaired with different materials. Furcal perforations created in 55 extracted human mandibular molars were repaired using either MTA-Angelus, Endocem, or Biodentine and coronally subjected to E. faecalis suspension for 21 days. The specimens were then stained using a LIVE/DEAD Viability Kit and visualized by CLSM. The minimum and maximum depths of bacterial penetration into the dentinal tubules were 159 and 1790 μM, respectively, with a mean of 713 μM. There were significantly more live than dead bacteria inside the dentinal tubules (p = 0.0023) in all groups, and all three repair materials exhibited a similarly sized stained area (p = 0.083). However, there were significant differences in the numbers of dead bacteria at the circumference of the perforation defect (p = 0.0041), with a significantly higher ratio of live to dead bacteria in the MTA-Angelus group (p = 0.001). Following perforation repair, bacteria may colonize the interface between the repair material and dentin and may penetrate through the dentinal tubules. The type of repair material has a significant effect on the viability of the colonizing bacteria.
