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.
