Study Notes
Argon Laser in Dentistry
- Argon laser produces high intensity visible blue light with a wavelength of 488nm.
- This light is capable of initiating photopolymerization of light-cured dental restorative materials.
- Camphoroquinone is used as the photoinitiator in these materials.
- Argon laser curing results in a lower temperature increase at the level of the dental pulp compared to conventional quartz tungsten halogen lamp units.
- Argon laser radiation can alter the surface chemistry of both enamel and root surface dentine.
- This alteration reduces the probability of recurrent caries.
- The use of argon laser provides two clinical benefits: reduced curing time and improved depth of cure.
