starlight s + 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. Although most composite materials are activated within this wavelength range, in case of uncertainty consult the specifications of the composite material or contact the manufacturer. 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 s + is a device 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 s + is used to activate the camphorquinone photoinitiator.

1.2.1

Patient Group Directions

This medical device is designed to be used with the following patient population: •

Children;

•

Adults;

• •

Adolescents; Elderly.

This medical device can be used on any patient (if applicable) of any age, weight, height, gender and nationality.

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.  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.

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. CAUTION: If the optical fibre is damaged or not efficient, this will reduce the intensity of the light being emitted considerably. In such cases it should therefore be replaced.  WARNING: During the intervention on the patient, do not perform any maintenance tasks on the system.

4.4

Instructions for Use

starlight s + allows performing 3 types of exposures: •

FAST : light emission at maximum intensity;

•

SOFT: emission 70% of maximum power for whole cycle.

•
