In vitro antimicrobial activity of AH Plus, EndoREZ and Epiphany against microorganisms

Abstract

It could be concluded that AH Plus and EndoREZ showed antimicrobial activity against all the tested microorganisms. No antimicrobial activity was observed for Epiphany.

In VitroEvaluation of the Antimicrobial Efficacy of Four Endodontic Biomaterials againstEnterococcus faecalis,Candida albicans, andStaphylococcus aureus

“…These results are in accordance with other studies where fresh AH Plus and iRoot SP had antibacterial action against E. faecalis by time kill assay [ 15 ], ADT, DCT, and modified DCT [ 1 , 2 , 16 , 17 ].…”

Eficacia antibacteriana de tres selladores endodónticos frente al Enterococcus faecalis

“…El sellador resinoso AH Plus posee una composición similar al sellador a base de resina epóxica Topseal, cemento endodóntico utilizado en esta investigación (11). Maekawa et al, en el 2012, utilizaron el método de difusión en agar Müller-Hinton para comprobar la actividad antimicrobiana de selladores endodónticos frente al Enterococcus faecalis y otras especies bacterianas comunes en las infecciones del sistema del conductos radiculares (12). La media del halo inhibitorio del sellador resinoso AH Plus fue de 7,92 mm que guarda similitud con el halo inhibitorio provocado por Topseal, utilizado en esta investigación.…”

In vitro Comparative Evaluation of the Antibacterial and Antifungal Activities of Different Root Canal Sealers against Endodontic Pathogens

“…20 The reports of few studies state that EndoREZ also showed greater inhibition zones. 15,21 Ustun et al 22 and Zhang et al 23 showed that EndoREZ was still bacteriostatic on the 7th day.…”

“…6,8 It adapts closely to the canal walls with minimal shrinkage after setting, and has long-term dimensional stability and better sealing properties due to good flow. 19,21,22 The reason for the high antibacterial activity of this sealer could be due to the unpolymerized residues during polymerization, in addition to the amine and epoxy resin components of the sealer. 19 The oxygen inhibition layer of the surface of any polymerizing resin leaves an uncured monomer layer, which could be another reason.…”

“…15,23 Other studies showed that AH Plus exhibited the highest antimicrobial activity. 6,20,21 Few studies reported that AH Plus had no antibacterial action. 14,16 Also, positive results go in favor of our present study.…”
