The epidemiological studies from available foreign literature deal with statistical processing of results obtained from the examination of workers from hazard workplaces in light and heavy industries. The effect of chemical and biological noxae on teeth decay and mucosa of the oral cavity was studied in a series of workers divided according to sex, age, and duration of employment. The harmful effect of noxae was found on the incidence and course of periodontopathies and worsened oral hygiene. No correlation was observed between the type of noxa and teeth decay. Noxae affect negatively the whole organism.
