Comparative evaluation of the apical sealing ability of a ceramic based sealer and MTA as root-end filling materials -An in-vitro study

Abstract

BackgroundThe present study was aimed to evaluate and compare the apical sealing ability of two endodontic root-end filling materials namely, iRoot SP (ceramic based) and ProRoot MTA using the bacterial leakage system.Material and MethodsA total of fifty recently extracted, single rooted teeth with a single straight canal were selected for the study. The teeth were chemo mechanically prepared. The apical 3mm of the root was resected and root end cavities were prepared. The teeth were randomly divided into two groups of twenty teeth each for the experimental root end filling materials namely, iRoot SP and ProRoot MTA. A two-chamber model was constructed using pippeter tips and plastic vials. The pipetter tips with the teeth were suspended in these caps and the entire assembly was reattached to the vial. The upper chamber was seeded withEnterococcus faecalis. An Enterococci-selective broth was used in the lower chamber. Leakage was assessed for 90 days and compared using survival statistics.ResultsThe ProRoot MTA filled root end samples leaked within 30-72 days. The iRoot SP filled root end samples leaked within 51-69 days.ConclusionsUnder the parameters of this study, it can be concluded that all the tested materials showed significant apical sealing ability as root-end filling materials over a period of 90 days. iRoot SP exhibited the most effective apical sealing ability as compared to ProRoot MTA. Key words:Apical sealing ability, Bacterial leakage, iRoot SP, ProRoot MTA, Root-end filling.

Clinical outcome of bioceramic sealer iRoot SP extrusion in root canal treatment: a retrospective analysis

“…iRoot SP has been reported to be less toxic [10][11][12][13][14][15][16][17] than AH Plus and MTA and to induce a relatively milder inflammatory response [18]. Furthermore, the excellent apical sealing ability of iRoot SP also accounts for the favorable outcome, which results in less apical microleakage of bacteria [19][20][21][22][23][24][25]. Additionally, this ability plays a role in continuously inhibiting bacteria [28][29][30][31][32], as well as promoting osteogenesis after root canal obturation [13,16,18,26,27].…”

“…Specifically, iRoot SP is more biocompatible than AH Plus and MTA [10][11][12][13][14][15][16][17] and induces a mild inflammatory response in mouse subcutaneous tissue [18]. In addition, iRoot SP possesses an excellent apical sealing ability, which results in less apical microleakage [19][20][21][22][23][24][25]. After root canal obturation, it could also play a role in promoting osteogenesis [13,16,18,26,27] as well as continuously inhibiting bacteria, such as Enterococcus faecalis, Candida albicans, and Staphylococcus aureus, which may be related to its high alkalinity [28][29][30][31][32].…”

Conservative endodontic management using a calcium silicate bioceramic sealer for delayed root fracture: A case report and review of the literature

“…IRoot SP is a biocompatible and nontoxic material that includes similar compositions to MTA and has both excellent physical properties, even in an inflamed acidic environment[ 26 , 27 ]. CS molecules within iRoot SP undergo hydration reactions that generate calcium hydroxide, which can inhibit pathogenic microorganisms and then react with phosphate, causing the precipitation of hydroxyapatite.…”

Cimentos biocerâmicos em endodontia: revisão integrativa

“…Entre o AH Plus ® , Endosequence BC Sealer ® e MTA Fillapex ® , notou-se que os biocerâmicos apresentaram melhor capacidade de vedação apical (Leal et al, 2011;Pawar et al, 2014;Asawaworarit et al, 2016;Ballullaya et al, 2017;Gandhi, Halebathi-Gowdra 2017;Mohamed et al, 2018;Wang et al, 2018;Candeiro et al, 2019). Isso pode ser explicado pela formação contínua de produtos de hidratação que reagem com íons de cálcio e fosfato de dentina, e levam à indução de precipitado de fosfato de cálcio.…”
