| Abstract |
Dentists and dental technicians are subjected to a wide variety of occupational exposures, including aerosols and airborne fine particles and nanoparticles having potential health effects. This study involved measuring the concentrations of ultrafine particles at a university dental clinic in Germany, using a handheld condensation particle counter. High concentrations of over 400,000 pt/cm3 were found when working with polymethacrylates in dental prostheses, which were however reduced by a factor of 20 by local suction. High levels of ultrafine particles were also observed when drilling zirconium oxide ceramics. Implications of these and other findings are discussed. |
