Objective This study evaluated the clinical effect of violet LED light on in-office bleaching
used alone or combined with 37% carbamide peroxide (CP) or 35% hydrogen peroxide …

High concentrations of hydrogen peroxide can cause adverse effects on composition and
structure of teeth. However, the addition of calcium and fluoride in bleaching agents may …

Objective To compare the effect of two bleaching systems (bleaching gel and whitening
strips) on the color change, roughness, and microhardness of enamel and two resin …

Objectives The objective of the study is to evaluate the bleaching potential of 6% hydrogen
peroxide (6% HP) gels containing NF_TiO2 or Nb2O5 irradiated with a violet LED light and …

Objective: The objective of this study is to evaluate clinical and patient reported outcomes of
different bleaching products. Materials and methods: Thirty participants were randomly …

Background This study aimed to evaluate the in vitro color of dental enamel bleached with
the violet LED, associated with or without low-concentration of peroxide; analyzed in two …

Objective The purpose of this study was to assess the hardness, mineral content, surface
roughness, and micromorphology of sound and slightly demineralized enamels, before and …

Background: The association of low concentration hydrogen peroxide (HP) and a light
source has been widely used to achieve efficient bleaching. We investigated the colorimetric …

Background Tooth whitening protocols with low concentration hydrogen peroxide (HP)
appear to minimize the microstructural effect on teeth. In addition, light sources have been …

Background This study aimed to evaluate the effects of an experimental bleaching gel made
with TiO2 and chitosan, along with the Opalescence Boost PF and Philips Zoom bleaching …
