ABSTRACT
PURPOSE:
To analyze and evaluate dust pollution in prosthodontic clinic and make proposal for reasonable protection.METHODS:
This study analyzed the particle size, element composition and dust concentration of 5 materials which were commonly used in dental restorations (veneering ceramics, cobalt-chromium alloy, photosensitive plastic, hard base resin, advanced artificial teeth) by using scanning electron microscopy (SEM), X-ray energy dispersive spectrometerï¼EDSï¼ and dust concentration laser tester, in order to assess the effects of prosthodontic dust posed on medical staff health and put forward reasonable suggestions for prevention and control of dust pollution.RESULTS:
The particle size of veneering ceramics, cobalt-chromium alloy, photosensitive plastic, hard base resin and advanced artificial teeth was (2.15±3.00), (33.78±24.33), (7.78±11.86), (31.16±44.35) and (28.45±39.21)µm, respectively. The time weighted average respirable dust concentration of veneering ceramics was 0.393 mg/m2 which was beyond the scope of national security.CONCLUSIONS:
Dust pollution is serious in prosthodontic clinic to which we should pay more attention and take appropriate prevention measures.
