starlight pro 1.1

Intended Use

Polymerisation of photo-hardening dental materials with a photoinitiator that can be activated in the wavelength band comprised between 440 and 480 nm with a narrow peak at 460 nm. Although most composite materials are activated within this wavelength range, in case of uncertainty consult the specifications of the composite material. This equipment may be used only in a dentist’s surgery or out-patient’s department where there are no inflammable gases (anaesthetic mixtures, oxygen, etc.).

1.2

Description of the Device

starlight pro is an equipment for polymerising photo-hardening composites. The light source used is a very high-efficiency monochromatic LED with a dominant wavelength between 440 nm and 465 nm. Unlike traditional halogen lamps, therefore, all the light being emitted by starlight pro is used to activate the camphorquinone photoinitiator. Furthermore, the light emitted by the diode is focused on the optical fibre by means of an optical elements, the shape of which was designed specifically for this purpose. The device consists of a charging unit with a brightness meter and a handpiece powered by a rechargeable lithium-ion battery. starlight pro can be used to operate in either of two emission modes: • •

Constant intensity of emission - FAST (cycle lasting 10 seconds);

Gradual intensity of emission - SLOW RISE (cycle lasting 20 seconds).

1.2.1

BATTERY

starlight pro is powered by a rechargeable lithium-ion battery already contained inside the handpiece, with no memory effect. starlight pro is equipped with two microprocessors that check the battery continuously and maintain the optimum battery charging parameters. The handpiece may therefore be placed back into the charging unit at the end of each treatment and left there, regardless of the charge of the battery.

5.1

New Battery - First Charging

NOTE: The battery of the starlight pro is provided partially charged. To charge completely the battery: 1. 2.

5.2

Place the handpiece into its housing in the charging unit (Figure 5 at page 10 - Ref. B). The green battery LED will light up (Table 1 at page 11 - Ref. B). The charging phase has been completed when the battery LED switch off.

Low Battery Indication

When the charge of the battery becomes low, after frequent use of starlight pro, the microprocessor will allow 6 more exposures to be carried out (FAST or SLOW RISE) without any need to recharge the battery. A battery low state is signalled at the end of each of these 6 cycles by means of 2 beeps. Once the 6 cycles have been completed, the handpiece enters a battery discharged state (see Chapter 5.3 on page 13). Place the starlight pro handpiece back into the charging unit.

5.3

Battery Discharged Indication

The battery of starlight pro is discharged if no light is emitted when pressing the on/off button and at the same time an acoustic signal is produced (2 beeps). Recharge the battery:

Battery Failure Indication

If the yellow battery LED (check) on the charging unit lights up (Table 1 at page 11- Ref. B), this means that there is a fault with the battery. NOTE: This failure condition disables operation of the charging unit. To restore proper working conditions proceed as follows: 1.

Remove the handpiece from the charging unit;

3.

Reconnect the cable of the charging unit. The green power LED will light up.

2.

5.5

Cut off the power supply to the charging unit for a few seconds (disconnect the power cable) - All the LEDs will light off;

Battery Replacement

To replace a failed battery, contact Mectron Customer Service.

5.6

Battery Safety Requirements

The battery can cause damage to property and/or personal injuries such as burns if conducting materials such as jewellery, keys or beaded necklaces come into contact with the exposed terminals. The conducting material could close an electrical circuit (short circuit) and become very hot. Make a habit of handling the device with care, particularly if it is placed inside a pocket, bag or other container in which there are metal objects. In the case of contact of the terminals with metal objects and consequent short circuit, the lamp stops and it is necessary to reposition it on the battery charger to resume its operation.  WARNING: Do not short-circuit the electric contacts of the handpiece with metal objects or liquids (Figure 6 at page 14 - Ref. A Ref. B).

Figure 6 – Electric contacts of the handpiece.  WARNING: Do not leave the battery within reach of children.

14

Battery CAUTION: Use only original Mectron batteries. The battery is of Lithium-ion type and, in case of malfunction, it can be replaced only by another battery of the same type and only by Mectron authorized personnel. CAUTION: Recharge the battery only with the Mectron charging unit (Figure 4 at page 8 - Ref. A). Do not attempt to recharge the battery using a generic battery charger. This entails a risk of explosion and fire. CAUTION: The battery should be recycled or disposed of in the appropriate manner in accordance with the law. The battery should not be thrown away with normal waste. The user will be liable for any damages caused by improper disposal of the battery. CAUTION: Do not use the battery for purposes other than those for which it is intended. CAUTION: Do not open, pierce or crush the battery. It contains toxic substances. CAUTION: Do not burn the battery or expose it to a high temperature. There is a risk of explosion. CAUTION: Do not short-circuit the battery terminals. This could cause burns and fire.

USE

6.1

Connecting the Accessories

 WARNING: Check the condition of the device before the treatment. Before each treatment, always make sure that the equipment is working properly and check the efficiency of the accessories. If any improper functioning is noted, do not proceed with the treatment. If the problem concerns the equipment contact an authorised technical assistance centre.  WARNING: Infections control. For maximum safety of the patient and of the operator, before each treatment, clean, disinfect and sterilise the optical fibre and the optical protection. Carefully follow the instructions provided in Chapter 7 on page 19.

Before using the starlight pro proceed as follows: 1. 2.

Manually insert the optic fibre onto the handpiece, applying gentle pressure. If necessary, rotate until it clicks into place (see Figure 7 at page 16); Fit the optical protection onto the optical fibre by hand (see Figure 7 at page 16).

Figure 7 – Connecting the Accessories

6.2

Safety Requirements During Use

 WARNING: Never point the beam of light in the direction of the eyes.  WARNING: Before each cycle of exposure make sure that the optical fibre is correctly and fully fitted into the handpiece.  WARNING: Before each cycle of exposure always make sure that the optical protection has been fitted onto the end of the optical fibre.

16

Use  WARNING: Point the beam of light directly onto the material to be polymerised. Do not subject the gum or other soft tissues to the beam of light (shield these parts suitably if necessary). The effect of the light should be limited to the oral cavity and in particular to the sector requiring clinical treatment..  WARNING: Do not short-circuit the electric contacts of the handpiece with metal objects or liquids (Figure 6 at page 14 - Ref. A and Ref. B).

CAUTION: During the first few seconds of exposure avoid contact of the tip with the material to be polymerised. Deposits of composite material adhering to and polymerised to the tip terminal surface lower the amount of light transmitted and will therefore prejudice subsequent polymerisation operations.  WARNING: Replace damaged or inefficient optical fibre as the light intensity is significantly reduced.  WARNING: During the intervention on the patient, do not perform any maintenance tasks on the system.

6.3

Instructions for Use

starlight pro allows performing 2 types of exposures: • •

FAST: exposure time of 10 seconds at the maximum light intensity.

SLOW RISE: exposure time of 20 seconds with a gradual increase of the light intensity during the first 3 seconds up to the maximum intensity.

FAST exposure selection: 1. 2.

Press the on/off button on the handpiece (Table 1 at page 11 - Ref. D) for a short time. An acoustic signal will be emitted (1 beep).

After 10 seconds an acoustic signal will be produced (1 beep). The FAST cycle has been completed.

SLOW RISE exposure selection: 1. 2. 3.

Keep pressed the on/off button on the handpiece (Table 1 at page 11 - Ref. D) for 2 seconds. An acoustic signal is emitted when the cycle starts and after 2 seconds. After 10 seconds an acoustic signal will be emitted (1 beep).

After 20 seconds an acoustic signal will be emitted (1 beep). The SLOW RISE cycle has been completed.

After the end of the treatment, place the starlight pro handpiece back into the charging unit (Figure 4 at page 8 - Ref. B). NOTE: Cycle interruption. Both in the FAST and in the SLOW RISE mode, the exposure cycle can be interrupted at any time by pressing the on/off button on the handpiece (Table 1 at page 11 - Ref. D). NOTE: Additional exposures. At the end of any exposure cycle, it is possible to carry out one or more additional cycles by pressing the on/off button on the handpiece again each time (Table 1 at page 11 - Ref. D). For a quick guide to the signalling, see Table 2 at page 12 and Table 3 at page 13.
