What is the difference between the bleaching efficacy of light-emitting diode and diode laser with sodium perborate?

Context

  • Currently, more and more patients attend dental clinics to have their teeth whitened. Dentists and patients continually seek better techniques and treatments in this field of dental aesthetics.
  • The contamination of the pulp cavity, irrigants, root canal and other restorative materials and pulpal injury may cause the discolouration of endodontically treated teeth 1, 2.
  • Hydrogen peroxide, sodium perborate and carbamide peroxide are widely used as intra-coronal bleaching agents for the treatment of discoloured teeth.
  • In order to provide faster and more effective treatment, bleaching agents have been used in association with an energy source with the goal of accelerating whitening gel’s oxi-reduction reaction 3.
  • Lasers have recently become popular as an energy source during intracoronal bleaching. Alternatively, LEDs are relatively low cost, and they require less energy to generate light 4.

Purpose of the Study

The aim of this clinical study was to evaluate the intra-coronal bleaching ability of a sodium perborate and distilled water mixture when activated by either a LED light or a diode laser.

Key Findings

Both the LED light source and the diode laser similarly and successfully bleached discoloured endodontically treated teeth with a mixture of sodium perborate and distilled water used as a bleaching agent.

    This does not say whether or not using light / laser activation was different than doing nothing at all.

    Well, it’s still a good summary.
