Abstract EN
Background: Today, the processes of teeth bleaching by utilizing oxidation chemical components became a public and important as a cosmetically operative.
Particularly the demanding on these processes increased with the developing in bleaching techniques, where laser light is used as catalyzer agent to increasing the efficiency and speed of these processes, and the latter known as office bleaching.
In this paper, we evaluate the effect of different laser wavelengths of bleaching on the surface hardness of the tooth and the temperature rise of the pulp due to the influence of laser light in conjunction with the bleaching gel.
Materials and methods: Three different laser sources (KTP 532nm, LD 810nm and Nd:YAG 1064nm) were used as accelerator agent in-office bleaching -utilizing Hydrogen Peroxide at 37.5%, where the enamel micro hardness measurements in the teeth (invitro study) pre and post operative was done.
Results: Then by using analysis of variance (ANOVA-Tukey's test p = 0.05 ) the results shows there are insignificant effects on tooth hardness due to the changes in the laser wavelengths in both pre and post bleaching.
Conclusion: Thereafter to evaluate the pulp chamber temperature rise induced by three different light sources employed in this laser-activated tooth bleaching, the pulp chamber temperature was measured during the radiation processes and the results shows ?hat the minimum temperature rise was seen at the 532nm.
So, we can say that the , KTP (SHG) Nd:YAG laser at the wavelength (532 nm) represent the best choice to use in-office bleaching processes.
