“…Thus, the second null hypothesis that VL and NTAP would not bleach teeth in the absence of HP or CP was rejected. According to the manufacturers' instructions, patients experiencing severe tooth sensitivity should apply VL up to 10 sessions without bleaching gel . According to our results, the effect of violet light on extrinsic stains cannot be discarded.…”

“…In view of this fact, the mechanism of action of VL alone may be restricted to extrinsic pigments on the enamel surface. Since protocols with VL alone are being constantly reported, further studies should investigate if enamel stained with other types of pigments would also benefit from VL irradiation, and clinical studies should demonstrate whether these results are translated into clinical conditions.…”

“…To overcome HP limitations, a novel generation of violet light‐emitting diode (VL) source for in‐office bleaching has been introduced in an attempt to replace the use of bleaching gels on patients with moderate to severe tooth sensitivity . As the wavelength of violet light (approximately 405 nm) differs from that of blue light (peak at 467 nm), which is commonly employed in in‐office bleaching, it was speculated that the light emitted from the new device could match the absorbance peak of the staining molecules adhered to the enamel surface .…”

Objective: The aim is to evaluate the effect of violet light (VL) and nonthermal atmospheric plasma (NTAP) combined with or without 35% hydrogen peroxide (HP) and 37% carbamide peroxide (CP).Methods: Bovine crowns were divided into (n = 10) VL, VL/HP, VL/CP, NTAP, NTAP/ HP, NTAP/CP, HP, CP, and C (control) groups. Color and whiteness change (CIELAB-ΔE ab, CIEDE2000-ΔE 00 , whiteness index-ΔWI D ), color parameters (ΔL, Δa, and Δb), and intrapulpal concentration (μL/mL) of HP were assessed by spectrophotometry.Scanning electron microscopy evaluated the morphology of enamel surface. Data were analyzed by two-way analysis of variance and Tukey (ΔE ab , ΔE 00 , ΔWI D , ΔL, and μL/mL) and Kruskal-Wallis and Mann-Whitney tests (Δa and Δb, α = 5%).Results: VL increased ΔE ab and ΔWI D of CP (P < .05). VL and NTAP alone resulted in perceptible color and whiteness change, but lower than those in the gel-treated groups (P < .05). Activation modes increased ΔL compared with that of C, but only VL enhanced Δb when applied alone or combined with CP. VL and NTAP did not increase HP diffusion (P > .05) or cause alterations in enamel morphology. However, HP and CP promoted topographical changes.Conclusion: VL and NTAP changed color to a lesser extent than bleaching gels. VL produced supplementary effectiveness only for CP (ΔE ab and ΔWI D ), without increasing HP diffusion or changing enamel morphology. Clinical Significance: Although violet LED light and nonthermal atmospheric plasma (NTAP) promoted in vitro perceptible bleaching without compromising enamel morphology, bleaching gels (hydrogen peroxide and carbamide peroxide) were more Part of this work was presented during poster session of the Annual Meeting

“…In endodontically treated teeth with little loss of tooth structure, endogenous whitening is the first option for restoring colour. Non-vital tooth whitening techniques include the inside/outside closed technique 5 , which uses hydrogen peroxide as an active ingredient, the activation of which can be accelerated by the action of violet LED 1,2,4,6,7 .…”

“…Violet LED is an option for tooth whitening, as the emitted photons interact with the chromophore molecules present in the enamel and dentin, breaking them down into smaller molecules [1][2][3]6,8,9 . This is possible because the wavelength of violet LED (405-410 nm) coincides with the absorbance peak of these molecules, promoting the whitening of the tooth structure [1][2][3][4][6][7][8][9] . In addition, violet LED is within the electromagnetic spectrum capable of biological interaction without molecular damage 3,7,10 .…”

Violet LED in Bleaching Non-Vital Teeth: a Case Series

et al. 2022

Objetive: The main of this study was to clinically evaluate the effectiveness of violet LED in bleaching non-vital teeth. Case series: three clinical cases were selected (1, 2 and 3), which showed changes in the colour of specific teeth to shades A2, C4 and B3, respectively. Bleaching was performed over three sessions (one session/week). Each session consisted of 20 applications of violet LED for 60 s, with a 30 s interval between them. After bleaching using violet LED, 35% hydrogen peroxide was applied for 15 min in clinical cases 2 and 3, with continuous irradiation with the violet LED in the last 5 min. The dental bleaching using violet LED resulted in teeth with shades A1, C3 and C2 in clinical cases 1, 2 and 3, respectively. The application of 35% hydrogen peroxide with the violet LED further changed the teeth to shades A2 and C1 in clinical cases 2 and 3, respectively. Conclusions: the protocol used in this case series showed that whitening with a violet LED alone should be restricted to cases requiring small colour changes.
