�
DANGER: Do not short-circuit the electric contacts of the handpiece with metal objects or
liquids.
�
DANGER: The handpiece should not be sterilized.
Proceed as follows after each treatment:
1
Remove the fiber optic and optical protection from the handpiece.
2
Clean and disinfect the surface of the handpiece using a cloth moistened with a solution of mild
detergent/disinfectant having a neutral pH (pH = 7). Follow carefully the instructions provided by the
manufacturer of the disinfectant solution.
Allow the disinfectant solution to air dry on the handpice before placing it back in the recharging unit.
Above all, make sure that the electric contacts are completely dry.
NOTE:
Water-based disinfectants with a neutral pH are strongly recommended. Some alcohol-based
disinfectant solutions may be harmful and cause damage to plastic materials.
07.3 Sterilization procedure
�
WARNING: Carry out sterilization only in a steam autoclave.
Do not use any other sterilization procedures (dry heat, radiation, ethylene oxide, gas, low-temperature
plasma, etc.).
�
DANGER:
The handpiece and recharging unit must not be sterilized.
�
DANGER:
Infection control - Sterilizable parts.
To avoid infection caused by bacteria or viruses, always clean the following components after each
treatment:
1. Fiber optic;
2. Optical protection.
Sterilization of the above components have been validated by independent laboratory, using a
pre-vacuum steam autoclaving.
Recommend minimum sterilization parameters that provide a 10
-6
Sterility Assurance Level (SAL):
-
Three times pre-vacuum cycle
-
Minimum sterilization temperature: 132°C (interval 0 °C; + 3 °C)
-
Sterilization time: 4 minute
-
Drying Time: 10 min
Do not exceed 135°C
07.4 Cleaning, disinfection and sterilization of the optical fiber
�
WARNING: Do not use sharp-edged objects to clean the fiber optic.
Carry out the following operations:
1. Eliminate any residues of polymerized composites from the surface of the fiber optic with alcohol.
2. Disinfect the surface using a cloth moistened with a solution of mild detergent/disinfectant having a
neutral pH (pH = 7).
3. Dry.
4. Seal the fiber optic in a disposable bag on its own.
5. Autoclave sterilize the fiber optic.
