  • Page 3: Introduction

    SmartLite™ PS Scientific Compendium Introduction Unlike conventional halogen lamps, light emitting diodes (LED) produce light in the visible range of the electromagnetic spectrum via quantum mechanical effects using doped semiconductors. LED lamps emit highly efficient light in a limited wavelength range. The LED needs less power than a halogen light bulb, in which the light is generated by heating a tungsten filament in the presence of a halogen gas.
  • Page 4: Hand Piece

    SmartLite™ PS Scientific Compendium Hand piece Due to the compact design of the hand piece the SmartLite PS is very easy and precise to handle. Pressing the ON/OFF button activates the 10-sec standard cure. Several visual and acoustic signals give the operator information on the battery status and/or if the LED-tip is not properly connected to the hand piece.

  • Page 6: Light Output Stability

    SmartLite™ PS Scientific Compendium Light output stability It is well known from conventional halogen lights (QTH) that the curing performance is strongly dependent on the bulb. Towards the end of the bulb’s lifetime the output is seen to drop dramatically. As this can not be checked automatically, it is of outmost importance to test the QTH curing lamp on a regular basis in order to detect any deterioration in its curing performance.
  • Page 7: Thermal Radiation

    SmartLite™ PS Scientific Compendium Thermal radiation Besides the emission of visible light in the spectral range of approximately 400-500 nm all curing lamps radiate heat as well. The amount of heat that is radiated towards the tooth depends on the output power and the exposure time. A balance between high light power and low heat irradiation is needed to avoid the risk that heat may have on the pulp tissue and the oral mucosa.

  • Page 9: Curing Performance

    SmartLite™ PS Scientific Compendium Curing performance Depth of Cure according to ISO 4049:2000 The depth of cure of a restorative material correlates directly with the light output of a curing light. The higher the intensity of a curing light the more efficient the depth of cure. This usually is the result of a higher degree of conversion, which leads to a stronger material and an increase in durability of the resulting restoration.

  • Page 17 Do not use a device which has not been properly disinfected (see Chapter Maintenance). Protect LED Tip from contamination by applying a disposable, single patient use sleeve ® (DENTSPLY Disposa-Shield Never aim the light directly at unprotected soft tissues, as this may cause injury or irritation. Do not aim the light at eyes.
  • Page 18: Directions For Use

    SmartLite™ PS Scientific Compendium Light reflected from the tooth surface may also injure eyes. Use the protective shield supplied with the unit or suitable safety glasses, which shield effectively against blue spectrum light. If time intervals between exposures are too short, the LED tip may overheat and potentially cause soft tissue injury.

    Attach the LED Tip [2] to the hand piece [1]. The device is now ready for operation. Protect LED Tip from contamination by applying a disposable, single patient use sleeve ® (DENTSPLY Disposa-Shield Attach the eye protecting shield to the tip or use safety glasses which shield effectively against blue spectrum light.
