Dental Curing Lights

Key Points

  • The ability to easily and effectively cure polymer-based restorative materials using light energy has revolutionized the field of dentistry over the past 50 years.
  • For a light-cured resin-based restoration to function and last as intended, it must receive the required amount of light energy at the proper wavelength (i.e., the wavelength of the photoinitiator) to facilitate optimal polymerization (or curing).  
  • To deliver the required amount of light energy, it is necessary to understand how clinical variables such as curing tip distance and angle of incidence with respect to the restoration surface influence the curing process, as well as exposure time and curing tip diameter.
  • Proper infection control procedures when using curing lights support both patient safety and equipment maintenance.
  • It is important to consider that curing lights can cause an intrapulpal temperature rise. Proper eye protection helps prevent blue-light-induced retinal injury.
