The inhabitants of industrial areas are influenced by anthropogenic factors. Harmful chemicals enter the body from the air, drinking water, food and are found in the oral fluid, hard tooth tissues, dental deposits, biopsy of tissue structures and contribute to the development of caries and inflammatory periodontal diseases. Toothpastes and mouthwashes are used for prevention of major dental diseases. The toothpastes contain a variety of abrasives: silicon dioxide, calcium carbonate, titanium dioxide, calcium bicarbonate, hydroxyapatite, which can act as adsorbents of heavy metal compounds. Biomonitoring using inductively coupled plasma mass spectrometry (ICP-MS) allows to determine the micro-quantities of metals in blood, urine, human milk, hair and oral fluid. The study of oral hygiene products showed that toothpastes and mouthwashes, used by patients for prevention and treatment of inflammatory periodontal diseases, have an adsorption activity for metal ions. The article evaluates the adsorption efficiency of medical and preventive toothpaste relative to the metal ions (chromium, manganese, cadmium, lead, etc.) in the oral fluid of the inhabitants of industrial areas. The use of adsorption-effective toothpaste twice a day for two weeks showed a significant decrease in the concentration of metal ions in the mixed saliva of the inhabitants which are under the influence of unfavorable environmental factors. When using a toothpaste containing silicon and titanium oxides, the concentration of manganese, chromium, arsenic, lead and cadmium ions in the oral fluid decreases within 2 weeks. The modern method of ISP-MS is advisable to use for high-precision monitoring of the oral fluid ion composition in patients living in the industrial areas.
