Antibacterial Activity of EndoSequence Root Repair Material and ProRoot MTA against Clinical Isolates of Enterococcus faecalis

Evaluation of selected properties of a new root repair cement containing surface pre-reacted glass ionomer fillers

“…The ability of MTA to create an alkaline environment may explain its antibacterial effect against E. faecalis [6]. Previous studies have also demonstrated a significant antibacterial effect of MTA, IRM and glass ionomer like material against E. faecalis without being able to totally eliminate the bacterium [4,5,40].…”

“…The antibacterial test used in this study was a modified direct contact test, which is a common antibacterial test used in the endodontic literature to test the antibacterial properties of root cements [4] and sealers [30]. However, the main limitation of the regular direct contact test is that it does not allow evaluation of microorganisms under biofilm conditions [5] because any attempt to disrupt the bacterial biofilm on cement surfaces would lead to crushing of the unset cement samples. Therefore, the modified direct contact test was performed on set cement samples in the current study in order to be able to vortex the tested cement samples and evaluate the bacterial biofilm grown on the specimen surfaces as well as planktonic bacteria around the samples.…”

“…The most widely used root-end filling material is a mineral trioxide aggregate (MTA), which is a calcium-silicate cement. MTA possesses several advantages, such as good sealing ability [1], acceptable mechanical properties [2], biocompatibility [3], and some antibacterial properties [4,5]. However, the main drawbacks of MTA are its high cost, low radiopacity, difficult manipulation and long setting time [2,6].…”

“…The aim of this study was to evaluate selected antibacterial, physiochemical and bonding properties of a prototype S-PRG filler-based root repair cement in comparison to commercially available materials used as root repair cements, namely MTA and IRM. 5 suspension and incubated for 48 hours. Glass tubes containing the same volume of bacterial suspension without cement discs were also incubated as controls.…”

Effect of Er,Cr:YSGG laser irradiation on apical sealing ability of calcium silicatecontaining endodontic materials in root-end cavities

“…These gaps might be associated with its long setting time, which then led to material washout during setting. In pilot studies, it was observed that this material started to set only when completely covered with water 29) . A recent study reported that EndoSequence Root Repair Material (marketed as iRoot BP in Canada; Brasseler USA, Savannah, GA, USA) incubated at 37°C in 100% humidity was unable to withstand a 500-g load until after a duration of 168 h (7 days) 30) .…”
