Figure 3

Levels of RLU in droplets and aerosols in various areas around the dental chair. Areas positively detected in A group (None) were selected, and the effects of B group (oral suction), and C group (extraoral and oral suction) on the levels of RLU that indicate luminous activity of ATP to luciferin/luciferase are presented. Locations in No. 3–5, No. 8, and No. 12–14 were indicated in Figure 2. The data indicate the mean ± standard deviation (SD) of three independent experiments. An asterisk indicates a significant difference among the three groups (*: p < 0.05, A–C).
