The white stains that orthodontic brackets often leave on teeth are a result of enamel demineralization caused by bacterial proliferation in the adhesive area, especially when accompanied by inadequate oral hygiene. Researchers have compared the efficacy of three new types of experimental adhesives, with bactericidal and enamel remineralisation properties which could prevent the appearance of these white stains around the brackets. The study compares three experimental dental adhesives which contain a bioactive nano – mineral called halloysite and whose nanotubes have been loaded with triclosan, a strong antibacterial and fungicidal agent in different concentrations: 5, 10 and 20 per cent. The research compares the three new, experimental biomaterials’ polymerisation properties, their antibacterial strength and bioactive properties, which not only prevent demineralization of the teeth, but also promote remineralisation.
