Table showing a statistical comparison of the normalised particle counts in both the ultrasonic scaling and high-speed handpiece procedures, for all the suction devices: Standard high-volume suction (‘HVE’); Purevac® HVE Mirror Tip connected directly to the suction port (‘Purevac (−H)’); Purevac® HVE System which included the lightweight hose and adapter (‘Purevac (+H)’); Standard low volume suction (‘LVE’); Ivory® ReLeaf™ hands-free suction device (‘ReLeaf’); DryShield® Isolation System (‘DryShield’). Statistical comparison excludes no suction. All suction devices showed a statistically significant reduction in normalised particle count vs no suction (data not shown) (p < 0.001). Statistical analysis was carried out using one-way ANOVA with Tukey’s post-hoc test
* p < 0.05, ** p < 0.01, *** p < 0.001, '–' not significant
