Fig 1.
Description of the parameters used to describe the average size distribution detected above background. The mode width is described by log sigma (σ) and the peak of the mode by DP,C. Mode amplitude parameter (N) was not compared, as it is highly dependent on sampling variability.
Table 1.
Dental procedures for which aerosol was detected above background.
Fig 2.
Box and whiskers plot of total aerosol number concentration for baseline measurements (orange) and dental procedures for which aerosol was detected above mean background value (green).
The aerosol number concentration is reported on a logarithmic scale.
Fig 3.
Size distribution data for ultrasonic scaling (a, b), 3-in-1 (c, d) and slow-speed drilling (e, f). Mode 1 (red line), mode 2 (green line), mode 3 (dark blue line) and cumulative bi- or tri-modal fit (blue line). 95% confidence band is shown as the red shaded area, n = number of procedures and error bars represent (± standard error).
