Bacteria residing in the oral cavity penetrate freely through the resultant fissures under the fillings, which might lead to the development of secondary caries. Nowadays dentistry, different nanotechnological materials with antibacterial activity are being developed for oral cavity disinfection. This study aims to investigate the antibacterial activity of a new cavity disinfectant NanoCare Plus Silver Gold (NanoCare) in comparison to (0.2%) chlorhexidine (CHX) gluconate disinfectant against growth and colony count using Agar well diffusion method and contact test, respectively, and also, to assess the nanoparticles (NPs) size distribution and Zeta potential of a NanoCare disinfectant. A total of 36 samples of cavity disinfectants were divided into two main groups (G) ( = 18); G1: NanoCare, and G2: CHX. Each group was subdivided into two subgroups (C) ( = 9) according to the antimicrobial test that the samples were subjected to. A chlorohexidine group demonstrated the higher mean in...
