[Evaluation of the effect of the work environment on the state of the oral cavity].

2439 men and employed in 4 industrial plants of Szczecin area had their masticatory system examined. Onto the cards prepared for electronic data processing the information has been written on: oral cavity caries (IMF), oral mucosa membrane, periodontium, parafunction and T.M.J. dysfunction. The main exposure factors of those plants have been determined, namely: welding gas, aromatic hydrocarbons, fluorine compounds, and copper dusts. The IMF values, oral hygiene, periodontal diseases as well as the TMJ-dysfunction in the test workers have been found to be approximately similar to the relevant values of other populations and to vary with sex, age or poor hygienic conditions. On the other hand, the prevalence of oral leukoplakia and parafunction seems to be dependent on the working environment.
