Title Measurement of airborne bacteria and endotoxin generated during dental cleaning
Bibliographic information Feb. 2009, Vol.6, No.2, p.121-130. Illus. 62 ref.
Abstract This study was conducted to characterize bioaerosol generation during dental treatments performed in standardized conditions. Dental cleaning procedures were performed in an isolated treatment room with a controlled ventilation rate. Aerosols concentrations before, during and 2hr after dental treatments were determined using samplers in the breathing zones of dental hygienists. Fluorescence microscopy in combination with culture showed that dental staff and patients were exposed to up to 1.86 E+05 bacteria/m3 generated during treatments. Fortunately, bioaerosols returned to baseline within 2h after the dental procedures.
