Objective: The aim: To study the content of trace elements (cadmium and zinc) in the blood and oral fluid in people with generalized periodontitis and work and live permanently in adverse environmental conditions.
Patients and methods: Materials and methods: In order to study the prevalence of periodontal diseases in adults living in areas with high level of soil contamination with heavy metal salts and working in the workplace with occupational hazards, there were studied 163 people who did not have somatic diseases, namely: 133 employees of Burshtyn Thermal Power Plant (TPP) and 30 persons who do not work at Burshtyn TPP.
Results: Results: The results of biochemical examination of blood and oral fluid in persons with generalized periodontitis of the I, II degree of severity and being exposed to adverse environmental factors, show changes in the trace element spectrum of blood and oral fluid, namely: a decrease in amount of zinc and an increase in amount of cadmium, which may indicate the disorder of microelement metabolism under conditions of chronic influence of small doses of salts of heavy metals.
Conclusion: Conclusions: As a result of the performed study, a violation of micronutrient metabolism in biological fluids (blood and oral fluid) was found in persons exposed to adverse environmental factors.
