too close to the autoclave heating element.
The spray head tubing (C) must be replaced after every patient,
but can be autoclaved with the handpiece. Failure to replace this
tubing after every treatment session between patients can result in a
hole forming in the tube from the abrasive stream. This will result in
leakage of air/abrasive, which will reduce cleaning efficiency and can
result in soft tissue trauma. The handpiece components are re-
assembled by assembling the inner tubing section firmly into contact
with the spray-head gasket, and then screwing the outer sleeve fully
onto the spray-head.
After numerous repeated cycles some change in the color of the
handpiece material may be noted. This will in no way affect the
function of the unit.
Should any clogging occur in the head or its transparent tube, this
can be easily handled by disconnecting the handpiece components
and cleaning the tubing and nozzle with a fine wire or reamer or by
placing the components in a small quantity of warm water in an
ultrasonic bath.

CORRECT
In Fig. 2 the head is angulated so that the stream is directed away
from the gingiva. Only the rebound spray is allowed to approach the
gingival margin.
In Fig. 3 the stream can be seen being directed towards the gingival
sulcus - THIS IS INCORRECT. Care must be taken at all times not
to direct the spray towards the lips and cheeks, or other oral soft
tissues. This can cause soft tissue abrasion and mild bleeding, but is
claimed to be of no clinical significance and usually heals
uneventfully in a few days.
WARNING
The spray should never be directed into the gingival sulcus or
onto the gingival margin, as this can result in unnecessary
abrasion of the gingival tissues and / or extension of the
