[THE STATE OF THE ORAL CAVITY LOCAL IMMUNITY DURING THE TREATMENT WITH METAL BRACKET-SYSTEM].

Objective - to study the effect of braces on the dentoalveolar system and the occurrence of changes in the body as a whole. The study involved 25 patients, 15 women and 10 men aged 20 to 45 years, with an anomaly of occlusion of the dentition in the transversal and sagittal plane, crowded position of the teeth of the upper and lower dentition. All patients were treated orthodontically on the MBT prescription bracket system made of high-quality steel grade 17-4. In patients, the bracket system was fixed to the light (double) curing adhesive ENLIGHT by ORMCO. All patients signed an informed consent form. Orthodontic braces are used to treat dental anomalies. Increased microbial contamination (poor hygiene) due to the appearance of additional retention points for plaque, trauma to the oral mucosa with parts of orthodontic devices, invagination and infringement of the gingival papilla by moving teeth are the main factors in the development of gingivitis, periodontitis and cheilitis during treatment with a bracket system. As a result of the study, it was revealed that the proteins of non-specific immunity sIgA and lysozyme were studied in the mixed saliva of patients with a fixed metal bracket system. It was found that in 40% of patients after 3 months. after treatment, local immunodeficiency develops, which requires antibacterial therapy and professional oral hygiene in these terms. In conclusion, it is noted that braces have both positive and negative effects on the dental system and the body as a whole, so when planning orthodontic treatment, patients with initially reduced local immunity of the oral cavity should be included in the risk group.
