Prevent Stains Of Orthodontic Brackets

The brackets(dental supplies) used for orthodontics may remain on the teeth due to enamel demineralization caused by bacterial proliferation in the area bound to the adhesive, especially when proper oral hygiene is not performed. Researchers at the Dental Department of the CEU Cardenal Herrera University (CEU-UCH) in Valencia, in collaboration with the Kings London School of Dentistry (UK) and the Federal University of Southern Brazil (Brazil), will demonstrate the efficacy of three new types of dental adhesives for experimental use. It has bactericidal ability and remineralization of enamel, which will prevent these white spots from appearing around the cradle.

CEU-UCH Salvatore Sauro and Santiago Arias professors of dentistry in collaboration with the Federal University of the Rio Grande do Sul State of Surrey and the King's College of Dentistry of Dentistry, Salvatore Sauro is an associate professor of honor. Published in the scientific journal "Dental Magazine", which is one of the most prestigious magazines in the world in this scientific field.

Sterilization and remineralization

The study compares three experimental dental adhesives that contain bioactive nanominerals, called halloysite, in their nanotubes with triclosan, an effective antibacterial and antifungal agent, at concentrations of 5%, 10% and 20%. The ability of polymerization, antibacterial activity and biological activity of three new experimental biological materials were studied and compared, which not only prevented tooth demineralization but also promoted its remineralization.

Three experimental materials tested in the dental equipment laboratory have demonstrated the ability to inhibit bacterial proliferation within the first 24 hours after administration, but only 20% of the samples with the highest triclosan concentration retain this capacity after 72 hours. With respect to remineralization capacity, the three materials tested were only proven to be effective after only two weeks of application to dental enamel samples submerged in experimental saliva.

These results assume promising progress in the development of new adhesives that can avoid the appearance of demineralization of the enamel around the brackets and at the same time remineralize the area, thereby avoiding the teeth White spots appear.
