Relevance. Research into the effects of nickel-titanium alloys and heavy metal ions on development inflammatory oral diseases is becoming increasingly significant in orthodontics. The relationship between toxic elements responses remains under-researched controversial. Data connection metals reactions could influence choice orthodontic appliance materials guide subsequent management monitoring patients with braces. question safe use alloy braces continues to be a relevant concern. Purpose. To assess levels fluid young braces, both those who developed plaque-induced gingivitis did not. Materials Methods. study involved 50 clinically healthy (Groups I II health categories) intact teeth, including compensated dental caries (isolated carious lesions – Grade I) no periodontal (PMA index <20), presenting crowding malocclusion (K07.2, K07.3). average age was 22.1 ± 2.7 years, all whom were undergoing treatment Oral samples analyzed for 12 using inductively coupled plasma mass spectrometry (ICP-MS) laboratory setting. Additionally, lysozyme activity pH measured before placement six months treatment. Results . Adaptation frequently complicated by periodontitis due impaired hygiene mechanical pressure exerted teeth gums, leading elemental imbalances. Patients during are particularly at risk developing such imbalances therefore require timely correction their mineral metabolism.

Introduction. In previous years, RUDN University conducted a comparative analysis of the ionomic profiles first-year students from Africa, Central Asia, Latin America, Middle East, China and others, but comparison elemental status East Moscow region has not been described in literature. The purpose study is to relationship between profile hair with natural climatic conditions living environment.
