The study involved 347 workers (232 men and 115 women) aged 35-44 from four big industrial plants in the area of Szczecin. Selected dental health indices and questionnaires filled by the workers have been analysed. The results were compared with the data obtained from the International Collaborative Study of Dental Manpower Systems in relation to Oral Health Status (so called "general population"). The study demonstrated differences in the DMF and M data between the test and the general populations. No differences in D and F numbers have been shown. Thus, the index of caries treatment requirements was similar in both populations. The awareness of caries treatment need was lower in the industrial than in the general population. The percentage of workers in demand of dentures was higher in the industrial than in the general population. The questionnaire study demonstrated that the test group more frequently applied--within last year--for dental care. Also, the availability of dental dispensaries was evaluated better by the workers as compared to controls.
