Appendix 2 Ultrasonic scaler and triple air procedure description including procedure detail, operatory type, duration of procedure and scavenger variation. EOS = extraoral scavenging, HVS = high-volume suction, ES = saliva ejector, RD = rubber dam. Frequency (n) denotes the mean number of times sites within that procedure were contaminated and mean intensity (%) of contamination. Clinician and assistant sites are reported separately
| Procedure | Code | Operatory type | Duration of procedure | Variation of procedure | Overall frequency of operatory site contamination (n) | Overall mean intensity operatory (%) | Maximum intensity operatory (%) | Maximum intensity operatory site name | Overall frequency of clinician contamination (n) | Overall mean intensity clinician (%) | Maximum intensity clinician (%) | Maximum intensity clinician site | Overall frequency of assistant contamination (n) | Overall mean intensity assistant (%) | Maximum intensity assistant (%) | Maximum intensity assistant site |
