Article Abstract
This study compared the effect of two whitening toothpastes on composite specimens discolored with 0.2% chlorhexidine (CHX). Twenty-four composite specimens were fabricated from Charisma Diamond composite resin. The initial color of specimens was measured according to the CIE L*a*b* color system using a spectrophotometer. The specimens were immersed in 0.2% CHX twice a day for 1 minute each time, for 2 weeks. The color of specimens was measured again, and the specimens were assigned to three groups (n=8). The control group specimens were immersed in distilled water. The two test group specimens were brushed twice daily for 21 days with Oral B toothbrush and Signal White Now and Crest 3D White whitening toothpastes each time for 30 seconds. The color of specimens was measured again. Data were analyzed by one-way ANOVA and t-test. CHX increased the a, b, and L color parameters in all groups. There were no significant differences in ΔL (P=0.10), Δa (P=0.24), and Δb (P=0.07) among the study groups. The a, b, and L parameters decreased after brushing the specimens discolored with 0.2% CHX with the whitening toothpastes. There were significant differences in ΔL (P=0.03), Δa (P=0.02), and Δb (P=0.01) among the three study groups after using the whitening toothpastes. The highest ΔL, Δa, Δb, and ΔE values were recorded in Crest 3D White group, followed by Signal White Now group. Crest 3D White whitening toothpaste had higher efficacy to resume the original color of composite specimens discolored with 0.2% CHX.

Effect of Blue Covarine Toothpastes on Tooth Colour: A Randomised Crossover Study.
Int Dent J
August 2025
Unilever Oral Care, Bebington, Wirral, UK. Electronic address:
Objective: To measure the effect of toothpastes containing blue covarine on tooth whiteness and yellowness.
Methods: This was a randomised, double-blind, 4-period, crossover design study conducted at a Chinese clinical research facility. Sixty-six participants with 2 natural upper central incisors (UCIs) with Vita tooth shade in range 2M2 to 3M3, without visible damage, gum recession, restorations or extrinsic/intrinsic stain, were allocated to evaluate 4 test toothpastes in random order using Williams square approach.
Whitening toothpaste-induced oral mucosal hypersensitivity reaction resembling oral lichenoid reaction: a clinically diagnosed case report.

This case report describes an instance of oral mucosal hypersensitive reaction resembling oral lichenoid reaction (OLR) induced by the use of a whitening toothpaste in a 28-year-old female patient presenting with extensive white hypersensitive reaction on the oral mucosa. The clinical features resembled an oral mucosal hypersensitivity reaction with lichenoid morphology. A detailed history revealed a clear temporal association between the onset of the reaction and the use of whitening toothpaste.

Objective: This study aimed to evaluate the effects of whitening toothpastes on the surface roughness and elemental composition of bioactive restorative materials.
Materials And Methods: A total of 210 disk-shaped specimens were prepared from Equia Forte HT (EF), Activa Bioactive Restorative (AB), Cention Forte (CF), Beautifil II (BF), and Filtek Z250 (FZ, control). The specimens underwent simulated toothbrushing using charcoal-containing, hydrogen peroxide (HO)-containing, and fluoride-containing toothpastes, as well as distilled water (control).

Purpose: This study aimed to evaluate the effects of simulated tooth brushing with different bristle types and two toothpaste formulations on the surface gloss and structural integrity of additively (AM) and subtractively (SM) manufactured resin composites and zirconia.
Materials And Methods: A total of 160 specimens were prepared from four material groups: AM resin composite (AM-RC), AM zirconia (AM-Z), SM resin composite (SM-RC), and SM zirconia (SM-Z). Each specimen was assigned to one of four subgroups based on toothbrush bristle type and toothpaste formulation.

Background: To evaluate the impacts of various charcoal-containing whitening toothpastes on color stability and surface roughness of a supra-nanofilled composite resin.
Methods: A total of 105 disc-shaped specimens were fabricated using a supra-nano spherical-filled composite resin and immersed in a coffee solution to induce staining. Color and surface roughness were measured before (T) and after staining process (T).
