The invention provides an assembly of a first and a second preparation to be mixed before or during endodontic treatment to form an endodontic irrigation solution. The first preparation comprises an oxidizing agent. The second preparation comprises antibacterial nanoparticles treated to slow their oxidation with the oxidizing agent. The antibacterial nanoparticles are, for example, encapsulated in shells according to a hybrid heart-shell structure. In one variant, the antibacterial nanoparticles are made of an alloy of at least two elements, one of the elements being more resistant to oxidation than the other. |
