In vitro and in vivo evaluation of deciduos teeth withening technique: the diode laser and light cure. <b>Brazilian Dental Journal</b>, v. 15, p. 93-93, 2004. Special issue.

The darkening resulting from these injuries create an aesthetic probem in these children in the middle of their psychosocial development. The whitening technique might be a satisfactory aesthetic resolution, as well as non-invasive. The objectives of the present study were to evaluate "in vitro" and "in vivo" the teeth color variation and superficial temperature, obtained by the thermocatalytic technique used in devitalized human deciduous teeth, as well as evaluate "in vivo" the teeth color variation obtained by the whitening. The whitening agent was the hydrogen peroxide 35%,having as a variant the source of catalyzing energy- diode laser and the light curer. 21 deciduous teeth were utilized. The light curer group-11 teeth and the laser group, 10.The color evaluation was carried out by the spectrophotometer and VITA 3D scale. After statistic analysis, it can be concluded that the whitening was verified by both methods.The temperature variation was significantly higher in the light cure group than in the laser group.93-93openAccessdentinteethhydrogen peroxidesemiconductor diodesbleachingResumos em periódicos15Special issue0000-0001-7404-9606https://orcid.org/0000-0001-7404-9606Sem PercentilSem Percentil CiteScore
