Direct the nozzle strictly towards the surface of the tooth, from the sulcus to the incisal edge.
Respect a distance of 3 to 5 mm.
The angle between nozzle and tooth must be set from 30 to 60 degrees. The flatter the angle is,
the larger is the area cleaned.
During treatment, direct the high-speed evacuator towards the air/powder jet deviated by the tooth.
The angle of reflection is identical to the angle of incidence.
