Low and high hydrogen peroxide concentrations of in-office dental bleaching associated with violet light: an in vitro study
ConclusionsUsing
violet light in conjunction with 6% or 35% HP does not alter the
physical properties of the bleaching agents, the penetration of HP or
enhance color change. However, an increase in temperature was observed
when violet light was applied associated with bleaching gels.Clinical relevanceWhile
the simultaneous use of violet light with hydrogen peroxide 6% or 35%
does not alter the material ' s properties, it also does not bring
benefits in reducing hydrogen peroxide penetration and improving color
change. Furthermore, the use of violet light increases pulp temperature.
