The induction of micronuclei in V79 cells by the root canal filling material AH Plus

Biomaterials, 2000
The in vitro micronucleus test (MNT) is an alternative to the chromosomal aberration assay for the detection of chromosomal mutations. Here, the epoxy resin-based root canal filling material AH Plus, the compounds paste A and paste B were tested for cytotoxicity and the induction of micronuclei in V79 cells.

Examination of cytotoxicity and mutagenicity of AH26 and AH Plus sealers

International Endodontic Journal, 2003
AbstractAim  To study in vitro the cytotoxic and mutagenic effects of AH26 and AH Plus.Methodology  Cytotoxic effects on Chinese hamster V79 cells were determined by counting viable cells following incubation with eluations of AH26 and AH Plus. In one set of experiments, the materials were mixed, set for 1 h and then eluted with dimethyl sulphoxide ...

The effect of AH 26 and AH Plus on MCF-7 breast cancer cell proliferation in vitro

International Endodontic Journal, 2002
The purpose of this study was to determine whether AH 26 and AH Plus have in vitro oestrogenic effects.MCF-7 breast cancer cells were trypsinized and plated in 24-well plates at initial concentrations of 10,000 cells per well in 5% FBS in DME. Cells were allowed to attach for 24 h; then the seeding medium was replaced with 10% CDHuS-supplemented phenol

Antibacterial and Anti-biofilm Activity of AH Plus with Chlorhexidine and Cetrimide

Journal of Endodontics, 2014
The use of root canal filling materials with antibacterial activity can be considered beneficial to reduce the remaining microorganisms in the root canal system, where Enterococcus faecalis is often found, and prevent recurrent infection. The aim of this study was to evaluate the antimicrobial activity and capacity for inhibiting E.
