Physicochemical properties and cytotoxicity of an experimental resin‐based pulp capping material containing the quaternary ammonium salt and Portland cement

Abstract

The experimental material possessed adequate physicochemical properties, low cytotoxicity and good calcium phosphate nucleation.

Synthesis and characterisation of modified antibacterial styrene-acrylate emulsions for polymer cement waterproof coatings

“…All antibacterial properties tests were performed via E. coli [Figure 6 (a)] and staphylococcus aureus [Figure 6 (b)]. The antimicrobial activity of the film is strongly dependent on the dosage of the quaternary ammonium groups, whereas the polymers with no MHDB presented much less effectiveness at inhibiting bacterial growth (Yang et al , 2018). We also observe that the films confer different antimicrobial activity to a couple of styles of bacteria, which means that the coating film possesses various sensitivity and specificity to bacteria.…”

Preparation of a highly crosslinked biosafe dental nanocomposite resin with a tetrafunctional methacrylate quaternary ammonium salt monomer

“…After incubations of 1, 3, and 5 days, the cell viability was assessed using Cell Counting Kit-8 (CCK-8 kit, APE BIO, USA) according to the manufacturer's instructions. For this process, 20 μL of CCK-8 dye solution was added to each well, and the cells were incubated for an additional 4 h. 43 Wells containing 200 μL of DMEM with 10% FCS and 20 μL of CCK-8 but without cells served as the blank control. The absorbance at 450 nm of the solution in each well was measured using a microplate reader (SpectraMax M5, Molecular Devices, Sunnyvale, CA, USA).…”

Eficacia antimicrobiana del cemento Portland y el Mineral Trióxido Agregado frente a Enterococcus faecalis y Candida albicans

“…Para mejorar sus propiedades antimicrobianas se ha propuesto la adición de una serie de agentes, los cuales no alteraron significativamente sus propiedades fisicoquímicas ni biológicas. Tal como los demuestran los estudios realizados al añadirle componentes antimicrobianos como monómeros de amonio cuaternario (Yang et al, 2018), Aloe Vera (Henrique Borges et al, 2017), nanopartículas de óxido de zirconio y óxido de niobium, óxido de zirconio, nanopartículas de plata entre otros (Song & Ge, 2019).…”
