Among the new technologies developed, low power
lasers have enabled new approaches to provide
conservative treatment. Low power
lasers act at cellular level, resulting in reduced
pain, modulating
inflammation, and improved tissue healing. Clinical application of the low power
laser requires specific knowledge concerning
laser interaction with
biological tissue so that the correct irradiation protocol can be established. The present case report describes the clinical steps involved in an indirect
composite resin restoration performed in a 31-year-old patient, in whom low power
laser was used for soft tissue biomodulation.
Laser therapy was applied with a
semiconductor laser 660 nm, spot size of 0.028 cm(2), energy density of 35.7 J/cm(2), mean power of 100 mW, and energy per point as 1 J, in contact mode, on a total of 2 points (mesial and distal), totaling 2 J of energy. The
therapy with low power
laser can contribute positively to the success of an indirect restorative treatment.
