“…The increase of temperature in pulp tissue during the light-curing process was assessed in five studies, by Optical Fibber Bragg grating sensors [ 21 ] or different types of thermocouples [ 20 , 22 , 29 ] inserted into the pulp chamber of extracted teeth, or intraorally but requiring tooth extraction after.…”

“…Gross et al compared specific scenarios that represented near similar radiant exposures (10 s with 1231 mW/cm 2 by Bluephase 20i ® and 1 s with 10,000 mW/cm 2 by the experimental LED-LCU—12.3 and 10.0 J/cm 2 , respectively—and 20 s with 1231 mW/cm 2 by Bluephase 20i ® and 2 s with 10,000 mW/cm 2 by the experimental LED-LCU—24.6 and 20.0 J/cm 2 , respectively). The authors concluded that there is no significant difference in pulp temperature changes between 20s/20i and 2s/EXP groups which in turn exhibited significantly higher temperature changes values than 1s/EXP and 10s/EXP [ 29 ].…”

High-Power LED Units Currently Available for Dental Resin-Based Materials—A Review

The pursuit of less time-consuming procedures led to the development of high-power light-curing-units (LCU) to light-cure dental-resin-based-materials. This review aims to describe high-power light-emitting-diode (LED)-LCUs, by a bibliometric systematization of in vitro and in vivo studies. The research-question, by PICO model, aimed to assess the current knowledge on dentistry-based high-power LED-LCUs by analyzing to what extent their use can promote adverse events on materials and patients’ oral condition when compared to low-power LED-LCUs, on daily dental practice. PubMed and B-on database search focused on high-power (≥2000 mW/cm2) LED-LCUs outputs. Studies assessing performance of high-power LED-LCUs for light-curing dental-resin-based-materials were included. From 1822 screened articles, 21 fulfilled the inclusion criteria. Thirty-two marketed units with high levels of radiant emittance (≥2000 mW/cm2 up to 6000 mW/cm2) were identified. Most output values vary on 2000–3000 mW/cm2. The highest output found was 6000 mW/cm2, in FlashMax™P3. Reports suggest that light-curing protocols with lower emittance irradiance and longer exposure outperforms all other combination, however in some clinical procedures high-power LED-LCUs are advocated when compared to low-power LED-LCUs. Moreover, long time exposures and over-curing can be dangerous to the biological vital pulp, and other oral tissues. Evidence showing that high-power LCUs are the best clinical option is still very scarce.
