Installation
CHARGING
- Plug the Type-C power cord into the charging base. Once connected, the light intensity indicator will be on. Put the curing light handpiece into the charging base, handpiece display screen will be on and shows CH(charging) during the whole charging process, when the battery is full, charging will stop automatically, and handpiece display screen shows FU(Full).
- Plug the Type-C power cord directly into the curing light handpiece. Once connected, handpiece display screen will be on and shows CH (charging) during the whole charging process. When battery is full, charging will stop automatically, and handpiece display screen shows FU (Full).
CURING LIGHT HANDPIECE
-
Insert the fibre optic light guide into the curing light handpiece with a TWISTING motion.
Ensure the fibre optic guide fits securely into the curing light handpiece. -
The battery is not fully charged prior to shipment. Please charge the battery for a minimum of 2 hours prior to the first use.
-
The curing light circuitry will automatically compensate for power fluctuation during use for a constant light intensity output.
-
Continually charging the curing light will not affect the life of the battery as it has a built-in safety function that will stop charging the battery when it is full.
-
The light intensity should be checked regularly with a light intensity meter.
Changing Of Settings And Use
-
Activate the curing light by pressing the ON/OFF or TIME/MODE switch ONCE.
-
The curing light is preset in the factory to the “FULL” mode for 10 seconds.
-
Press and hold the TIME/MODE switch for 2 seconds to change the mode.
Press the TIME/MODE switch repeatedly to locate the desired time for the “FULL” “PULSE”or “RAMP” mode. -
Every start and end of a programme or every change of time or mode, will be signaled with a “beep”.
-
The curing light will automatically turn off if it is not in operation for 1 minute. It will keep the last selected programme in memory once restarted.
-
Put on the disposable curing light sleeve to cover the entire curing light for cross infection control.
-
Put the protective light shield onto the light guide tip until it is firmly held on the curing light.
The curing light is now ready for use. -
Press the ON/OFF or TIME/MODE switch to activate the curing light if no indicator light is on.
When the preparation for light curing is ready, press the ON/OFF switch to start using the curing light. -
After the light curing process is finished, remove and dispose the curing light sleeve for every patient.
-
When the battery is low, the handpiece display screen shows Lo (Low) and the curing light can still work for about 30 times at 10s time mode, we suggest to recharge it in time.
Curing Light Mode Applications
| FULL | For general applications |
|---|---|
| PULSE | For more gentle processing, designed for reducing the shrinkage of |
composite.
RAMP| First 0-5 seconds are ramped for more gentle processing, designed for
patients sensitive to heat.
Depth Of Cure
MODE| Intensity mW/cm²| Time| Depth Measurements| ISO
4049 Depth Measurements (-50%)
---|---|---|---|---
FULL| 1600±10%| 10 seconds| 4.3 mm| 2.15 mm
PULSE| 1600±10%| 15 seconds| 4.2 mm| 2.10 mm
RAMP| 1600±10%| 15 seconds| 4.6 mm| 2.30 mm
Remarks : Above data is based on test results using an A2 shade composite. The light guide tip was placed above and pointed perpendicular to the composite. Tests were done as per ISO 4049 Standard. The samples were measured and the data was divided by two (50% of the total composite depth cured). ISO 4049 Standard requires that the results for class II restorative materials should be at least 1.5 mm for non-opaque shades and 1.0 mm for opaque shades.
All resins and composites have different curing times. It is recommended that you should test your resins and composites performance to determine the curing times required.
Data Is Only For Reference, Always Follow The Instructions From Your Resin And Composite Manufacturers
- There are many variables (distance and angle between the light guide tip and composite, area, shade, thickness and type etc.) affecting composite curing times. It is recommended to place and cure only 2 mm for each composite placement.
- Using a barrier sleeve for the curing light will reduce 5-10% of curing light intensity.
- The light guide tip should be placed approximately 1-2 mm above the resin or composite and pointed perpendicular to tooth surface.
- High intensity lights produce more heat, this is a direct indication of the power of light being emitted. When using the lights for more than 10 seconds, do not keep the light guide tip in one position. It is always recommended to use a dental syringe to blow a cold air flow on the area during long periods of curing. This will maintain a lower temperature for the composite and surrounding area, particularly when using rubber dam so as to avoid any rubber dam breakage due to heat built-up.
- Do not expose soft tissue to curing light for more than 2 seconds or burns may occur.
Cleaning And Disinfecting
Switch off the curing light and disconnect the Type-C cord of adapter. The
curing light handpiece and protective light shield can only be cleaned with a
non-alcohol based disinfectant wipe for cold sterilization only. Fibre Optic
Guide is autoclavable. Take the Fibre
Optic Guide off the curing light handpiece with a TWISTING motion, remove any
dirt or debris using a water soaked nylon brush, clean and dry with a wipe,
then autoclave as per ISO 17665-1 121°C (250°F) for a minimum of 15 minutes.
Always follow the autoclave manufacturer’s instruction.
