Abstract
Tooth whitening or bleaching is one of the most common dental procedures that optimize the white color of the teeth and minimize the simultaneous damage to the tooth structure. Light can speed up the whitening process with halogen lamps, light-emitting diodes, plasma arc lamps, and lasers. Our results show that combinations of a teeth whitening agent with laser light irradiation with a 0.44 µm blue laser diode or a 1.7 µm near-IR laser diode accelerate the whitening process not only during tooth irradiation but also within two weeks after the procedure.
Laser diode spectrum at the operating point was measured using a StellarNet BLUE-wave grating spectrometer for the 0.44 µm diode and a StellarNet Dwarf-star grating spectrometer for the 1.7 µm diode. The resulting laser diode emission …
