Figure 5 Intra-pulpal temperature rise after 10s exposure with various curing units
The temperature rise after a 10sec exposure using the SmartLite PS ranged from 2.4 to
2.8° C and was significantly lower than of the following commercially available LED and
halogen units: L. E. Demetron 1, Elipar FreeLight 2, Optilux 501, and Spectrum800.
Moreover, longer exposure times have shown that the SmartLite PS emits and transfers less
heat onto the tooth than other widely used LED and halogen curing lights.
5.2 Temperature of the LED Tip
ISO 60601 requires that equipment parts that may have a brief contact with a patient must
not be warmer than 50 °C. If SmartLite PS is used according to the directions for use, which
request a waiting period of 30 seconds between 10-second curing cycles, the device is in
compliance with the above-mentioned standard.
If, in deviation from the directions for use, the device is used with shorter waiting periods or
for longer curing cycles, the temperature of the LED Tip may rise above 50 °C. However,
experiments for curing cycles up to 30 seconds long have shown that, if typical direct
restorative procedures are simulated, the resulting temperatures do not create any hazard
regarding tissue compatibility and do not negatively affect the lifespan of the LED light. Still,
SmartLite PS must not be used for the luting of indirect restorations as this process is
associated with many consecutive and long curing cycles.
