Introduction: Clinical studies evidence that, in the laboratory of dental techniques, several toxic agents, with irritating, allergic and carcinogenic pathogenic effects are present. Consequently, during his activity, the dental technician is exposed to a series of noxious factors, which might affect his health condition.
Materials and method: The present study develops a quantitative analysis of the respiratory powders occurring in a laboratory of dental technique. The air samples were taken over from three rooms of the laboratory, along 8 hours, for 10 days.
Results and discussion: The data obtained are under the maximum values accepted for respiratory powders, however their high toxicity and the constant exposure, over long time intervals, draw special attention on the registered values.
Conclusions: The technicians working in dentistry laboratories should be aware of the risks and possible contamination sources, and prevention methods should be considered.
