15.5 Replacing the light conductor
in the Scaler handpiece
The light conductor must be checked regularly
for light transmission. Over the course of time it
becomes opaque or takes on a milky colour. This
impairs its ability to function and means that it
needs to be replaced.
The light conductor can be sterilised sev-
eral times. As soon as it starts to become
opaque or take on a milky colour, light
transmission begins to decrease.
