“…Different in vitro 4,6,13 and clinical studies 9,10,11,14,23 have investigated the effectiveness of whitening dentifrices and obtained contradictory results. Their efficacy has been determined by their relative ability to prevent or reduce the formation of extrinsic stains or tooth color changes over time.…”

“…As to lightness, ΔL showed a significant difference in G1 (Colgate Luminous White) at the second and third assessment points; however, no differences were observed when this group was compared with the other groups. Alterations in lightness have been attributed to the presence of high cleaning silica and of polyphosphates, 14 with removal of extrinsic stains and better results than conventional dentifrices. 25 Previous clinical studys 14 has shown the lightening action of Colgate Luminous White, but no noticeably visible change after 15 days of use.…”

“…12 This scale may be used in every object whose color can be measured. It is actually the most widely used system in different studies 6,12,13,14 and it is recommended by the American Dental Association. 15 Also, there are delta values associated with this scale (ΔL*, Δa*, and Δb*) which indicate how the sample differs from the standard for L*, a* and b* and are used to calculate total color difference (ΔE) by the formula ΔE = [(ΔL*) 2 + (Δa*) 2 + (Δb*) 2 ] 1/2 .…”

The aim of this clinical study was to evaluate tooth color changes (ΔE) and tooth sensitivity (TS) associated with whitening dentifrices. Sixty participants were selected according to inclusion and exclusion criteria and then allocated to three groups (n = 20): Colgate Luminous White (G1), Close Up White Now (G2) and Sorriso dentifrice (G3-control). The participants were instructed to use only the provided dentifrice and toothbrush in standardized oral hygiene procedures for 4 weeks. ΔE was assessed by spectrophotometry (CIELab System) whereas TS was determined by a visual analog scale at baseline and weekly using four assessment points. The data were analyzed by two-way ANOVA and Tukey's post-hoc test and Friedman test (α = 0.05). ΔE (baseline-assessment point 4) showed no significant difference (p>0.05) across the groups: G1 (ΔE = 5.1), G2 (ΔE = 6.8), and G3 (ΔE = 4.4). Δb (baseline-assessment point 4) was significantly different (p < 0.05) in G2 (3.8) when compared to G1 (-0.2) and G3 (0.3). There was no significant difference (p > 0.05) in TS at baseline. Both the control and whitening dentifrices caused similar tooth color changes (ΔE). There was no significant TS during the study period.

“…The growing appreciation of aesthetics has led the market to launch the Products OTC (over-the-counter), which are low cost and promise whitening action. The toothpaste is one of the forms of presentation 10,11 , among them that promise whitening action if used often and for a certain period of time. However, upon analyzing the composition of dentifrices, in some it is (64 patients).…”

“…Horn et al 11 assessed the composition of whitening action dentifrices and observed that none of the dentifrices analyzed presented hydrogen peroxide and did not present whitening action. In the present study, the dentifrice GC -Colgate® Luminous White Advanced has in its composition 1% hydrogen peroxide that when assessing the change of color showed a statistically significant change of color.…”

O objetivo deste estudo clínico foi avaliar, por 7 semanas, a eficácia de dentifrícios clareadores e a satisfação dos pacientes após o uso. Foram selecionados 30 pacientes que possuíssem todos os dentes anteriores nas arcadas superior e inferior, apresentando cor inicial A2, avaliados através da escala de cores Vita Classical (Vita Zahnfabrik, Bad Säckingen, Alemanha). Os participantes foram aleatoriamente divididos em 3 grupos (n=10): GA - Colgate® Máxima Proteção Anticáries (controle negativo), GB - Colgate® Luminous White e GC - Colgate® Luminous White Advanced. Os dentifrícios foram distribuídos em bisnagas idênticas e aleatorizados. As avaliações de cor foram realizadas inicialmente ao uso (baseline), após 7, 15, 30 e 60 dias, utilizando dois métodos: avaliação subjetiva com as escalas de cor Vita Classical (Vita Zahnfabrik, Bad Säckingen, Alemanha) e Vita Bleachedguide 3D-MASTER (Vita Zahnfabrik, Bad Säckingen, Alemanha), e avaliação objetiva através do espectrofotômetro VITA Easyshade Compact®, Vident, Brea, CA, USA). Foi considerada a satisfação do paciente quanto a mudança de cor dos dentes. Os dados foram submetidos à análise estatística, utilizando análise de variância (ANOVA) de três critérios e pós-teste de Tukey (α=0.05). Os resultados demonstraram que houve diferença de cor estatisticamente significante nos grupos em que se utilizou os dentifrícios clareadores (GB e GC), nos períodos entre 15 e 30 dias. Conclui-se que ambos os dentifrícios GB e GC apresentaram ação clareadora, observado através das escalas subjetiva e objetiva. Porém, na percepção do paciente apenas no grupo GC houve mudança de cor.Palavras-chave: Dentifrícios. Clareamento Dental.

The participants were randomly divided into 3 groups (n = 10): GA - Colgate® Maximum Antibody Protection (Negative Control), GB - Colgate® Luminous White and GC - Colgate® Luminous White Advanced. The dentifrices were distributed in identical and randomized tubes. The color evaluations were performed at baseline after 7, 15, 30 and 60 days using two methods: subjective evaluation with the Vita Classical (Vita Zahnfabrik, Bad Säckingen, Germany) and Vita Bleachedguide 3D- MASTER (Vita Zahnfabrik, Bad Säckingen, Germany), and objective evaluation using VITA Easyshade Compact® spectrophotometer, Vident, Brea, CA, USA). The patient's satisfaction with the teeth color change was considered. The data were submitted to statistical analysis using ANOVA of three criteria and Tukey post-test (α = 0.05). The results showed that there was a statistically significant difference in color in the groups in which the whitening dentifrices were used (GB and GC), in periods between 15 and 30 days. It was concluded that both GB and CG dentifrices presented a whitening action, observed through the subjective and objective scales. However, in the perception of the patient only in the CG group there was a change of color.Keywords: Dentifrices. Tooth Bleaching. Esthetics, Dental.
