Title Exposure to volatile methacrylates in dental personnel
Bibliographic information June 2005, Vol.2, No.6, p.302-306. Illus. 21 ref.
Abstract Exposures to 2-hydroxyethyl methacrylate (2-HMMA) and methyl methacrylate (MMA) were determined in five randomly-selected public dental clinics and at a university odontology faculty in Sweden, where whole-day and task-specific short-term measurements were performed. The median 8-h time-weighted averages were 2.5µ/m3 (dentists) and 2.9µ/m3 (dental nurses) for 2-HMMA and 0.8µ/m3 (dentists) and 0.3µ/m3 (dental nurses) for MMA. The maximum short-term exposure levels were 79µ/m3 and 151µ/m3 for 2-HMMA and MMA respectively for both dentists and dental nurses. These observed levels are much lower than for complete denture fabrication. Irritant effects would not be expected in healthy persons at these levels. Nevertheless, occupational respiratory diseases may occur, and improvements in the handling of these chemicals in dentistry are warranted.
