· Hence, insoluble, toothcolored, or colorless metal oxide powders such as silica, zirconia, alumina and zinc oxide (ZnO) may be more interesting in dental composites. Although the incorporation of ZnO into dental composites may impart antibacterial activity , the opacity of the particles against visible light may adversely affect the light curing and, consequently, the mechanical ...

Zinc oxide is a fluffy white to yellow white powder having a very fine physical particle size (% should pass a 325 mesh screen). It is made using one of two processes that produce different densities. The French process vaporizes and oxidizes zinc metal, the American process smelts a coal/zinc sulfide mix and oxidizes the zinc fumes.
Discussion. Powder/liquid ratio determination for each sealer was necessary due to the lower pH of eugenol, which decreases the speed of the chemical reaction between this liquid and zinc oxide, allowing incorporation of a greater amount of powder to the sealer (Sousa Neto, 1998).
The present study has shown that zinc oxide powder when added to GIC produces antimicrobial effect, which increases as the concentration of zinc oxide is increased. The antimicrobial effect of zinc oxide lasts at least for 1 month. The shear bond strength decreases as the concentration of ZnO increases.
