Particle counts for high-speed handpiece procedures. A-E, Line graphs showing particle count (> 0.3 µm/0.1 L air) over time for the high-speed handpiece procedures in the single (i) and dual sensor (ii) setups. A, Standard high-volume suction (‘HVE’). B, Purevac® HVE Mirror Tip connected directly to the suction port (‘Purevac (−H)’). C, Purevac® HVE System which included the lightweight hose and adapter (‘Purevac (+H)’). D, DryShield® Isolation System (‘DryShield’). E, No suction. Each line on the graphs represents one replicate. F, Bar charts showing normalised particle counts (mean ± SD, n = 5) for the ultrasonic procedures. Statistical analysis shown in Table 1
