|---|---|
| In order to establish a specific hygiene protocol for the period of orthodontic treatment with a Haas-type rapid palatal expander, we will analyze the changes in the oral microbiome caused by the presence of the fixed appliance and the difficulty in hygiene that it offers. Based on its resilience property, we will determine the time interval necessary for the reestablishment of the oral microbiome after treatment and removal of the appliance, as well as the influence of the application of the new proposed protocol in this time interval, by sequencing the 16s rRNA gene present in the collected samples. ;In addition, we will evaluate the relationship between the probable oral dysbiosis and the manifestation of infectious diseases of the oral cavity and halitosis in individuals with maxillary atresia admitted to the Postgraduate Clinic in Orthodontics of the School of Dentistry of the Federal University of Rio de Janeiro (UFRJ), RJ, Brazil, by identifying clinical parameters of periodontal disease, caries, integrity of the palatal mucosa and halitosis at different times, before and during treatment. | — |
