Development and characterization of a novel bulk-fill elastomeric temporary restorative composite

J. appl. oral sci; 27 (), 2019
Abstract Objectives: This study investigated the physical and mechanical properties, antibacterial effect and biocompatibility of novel elastomeric temporary resin-based filling materials (TFMs) containing zinc methacrylate (ZM). Material and Methods: Experimental TFMs were prepared by mixing the zinc ...

Two novel Mg(II)-based and Zn(II)-based complexes: inhibiting growth of human liver cancer cells

Braz. j. med. biol. res; 51 (2), 2018
Two new Mg(II)-based and Zn(II)-based coordination polymers, {[Mg3(BTB)(DMA)4](DMA)2}n (1, H3BTB=1,3,5-benzenetrisbenzoic acid, DMA=N,N-dimethylacetamide) and {(H2NMe2)2[Zn3(BTB)2(OH)(Im)](DMF)9(MeOH)7}n (2, Im=imidazole, DMF=N,N-dimethylformamide), have been successfully synthesized and structurally cha...

Two mechanisms of oral malodor inhibition by zinc ions

J. appl. oral sci; 26 (), 2018
Abstract Objectives The aim of this study was to reveal the mechanisms by which zinc ions inhibit oral malodor. Material and Methods The direct binding of zinc ions to gaseous hydrogen sulfide (H2S) was assessed in comparison with other metal ions. Nine metal chlorides and six metal acetates were exami...

Estudo comparativo da dureza superficial, resistência à corrosäo e rugosidade superficial de ligas metálicas alternativas

Há muitos anos, as restauraçöes metálicas fundidas com ligas de ouro vêm desempenhando grande funçäo nos trabalhos restauradores em odontologia, porém, a necessidade de substituiçäo das ligas, à base de ouro, em funçäo do seu alto custo, fez surgir no comércio odontológico uma grande quant...
