Cytotoxicity assessment of graphene-based nanomaterials on human dental follicle stem cells

Toxicity and efficiency study of plant extracts-based bleaching agents

“…This effect was previously reported on FM3A cultures [27] for Opalescence. Others also reported toxic effects of pulp capping materials [21] and hydrogen peroxide bleaching gel on fibroblasts [1] and odontoblastlike MDPC-23 cells [18].…”

“…Cells were cultured in Dulbecco's modified Eagle's medium (DMEM), supplemented with 5 % fetal calf serum, 50 μg/ml gentamicin, and 5 ng/ml amphotericin (Biochrom Ag, Berlin, Germany). Human dental follicle stem cells, prepared as previously described [21] were a generous gift from Olga Soritau PhD, Institute of Oncology, ClujNapoca, Romania. Cell cultures in the fourth-sixth passages were used.…”

Antibacterial Activity and Biocompability of Zinc Oxide and Graphite Particles as Endodontic Materials

“…Carbon nanomaterials such as fullerenes, carbon nanotubes or graphene, other carbon allotropic forms, have been widely studied regarding their toxicity towards bacteria and human cells [37][38][39] . Carbon nano-sized, were used to enhance the performances of implants, as tissue engineering scaff olds 40,41) and as composites on human dental follicle stem cells 42) . However, in general, their biological applications depend on the synthesis method and functionalization 42) .…”

Solubility, ductility and resilience of a PMMA denture resin with graphene and silver nanoparticles addition

“…The graphene-silver nanoparticles (G-Ag) composite was synthesized through the Radio-Frequency Catalytic Chemical Vapor Deposition (RF-CCVD) method [41] [Jatania] using silver nanoparticles distributed over magnesium oxide (Agx/MgO, where x = 3 wt %) and graphene oxide, obtained as previously described [42]. Mixing of G-Ag with acrylic denture material was done in 95% ethyl alcoholic solution, at room temperature, under continuous stirring, for 30 minutes.…”
