ABSTRACT

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.

The objective of this clinical study was to evaluate, for 7 weeks, the efficacy of whitening dentifrices and the patients' satisfaction after use. 30 patients were selected who had all the anterior teeth in the upper and lower arches, presenting an initial color A2, evaluated through the Vita Classical color scale (Vita Zahnfabrik, Bad Säckingen, Germany). 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. (AU).
