described here may lead to a dangerous exposure to radiation.
Improper use, Sirona
Sirona Dental Systems GmbH cannot be held liable for any damage
caused by improper use or non-compliance with the instructions and
information provided in this manual.
Never direct the laser beam toward paper, plastics or objects with dark
surfaces. They could catch fire due to the high temperatures produced by
the laser beam.
The unit is not suitable for use in the presence of anesthetics that are
flammable when in contact with air, oxygen or nitrogen monoxide.
Oxygen-saturated materials such as cotton wool can catch fire owing to
the high temperature that the unit reaches during operation. Label
removers and flammable solutions used for cleaning and disinfecting the
SIROLaser Advance should be allowed to evaporate before using the
device. Observe fire hazards caused by flammable gases.
If any tissue is unintentionally irradiate, this may lead to burns. This risk
can be reduced by surrounding the target area with moistened sterile
drapes or gauze doused in salt. These covering materials must meet the
requirements of laser surgery.
A extractor or a filter should be used. The operating personnel should be
aware that biologically active material could get into the enviroment. It
may contain particles of viable tissue.

Laser protective goggles

All persons present in the room (patient, dentist and assistant) must
always wear the laser protective goggles delivered along with the
SIROLaser Advance.
Before using the laser protective goggles, please read and observe the
instructions for use provided by the manufacturer and attached to the
goggles in the case. Make sure that the laser protective goggles:
● are not damaged
● conform to standard EN 207 with protection level LB5
● are suitable for the correct wavelength (labeled on the goggles)
These instructions apply particularly when using goggles supplied from
an outside source that are not included in the scope of delivery of the
SIROLaser Advance.
Never use optical instruments such as microscopes, eye loupes or
magnifiers together with the original protective goggles. Otherwise
sufficient eye protection can no longer be ensured.
