Experimental dental resin composites containing copper-doped mesoporous bioactive glass nanospheres (Cu-MBGN) were developed to impart anti-bacterial properties. Increasing amounts of Cu-MBGN (0. 1. 5 and 10 wt%) were added to the BisGMA/TEGDMA resin matrix containing micro- and nano-fillers of inert glass. https://www.ngetikin.com/quick-offer-1-Gallon-Universal-Primer-Pro-Deep-Penetrating-Primer-big-deal/
