4. Release the pedal and wait until the spray stops.
When removing the foot from the control pedal, the air/powder jet continues for a few more seconds.
Take these seconds into account.
5. Remove the nozzle from the pocket and repeat the operation in the next pocket.
Never spray outside periodontal pockets. External operation accelerates nozzle wear and causes
a multidirectional spray jet which can be unpleasant for the patient.
