ABSTRACT
This randomized clinical trial evaluated the whitening potential of commercially available toothpastes. Sixty patients were selected and randomly divided into 4 groups (n=15), according to the dentifrice used GI (control) - Colgate Total 12, GII - Close-up White Now, GIII Oral-B 3D White, GIV Colgate Luminous White. Three daily brushings were performed for 2 to 3 min each, during a period of 15 days. Patients had the color of their teeth evaluated before and after the treatment by means of a spectrophotometer (Vita EasyShade - CIE L*a*b*). Data obtained from L values were analyzed by one-way ANOVA and t test. ∆E was also evaluated to calculate color alteration, by NBS criteria. Mean (standard deviation) of initial values were GI 82.9 (4.9); GII 83.9 (5.8); GIII 83.9 (7.2); GIV 86.4 (3.4) and final values were GI 84.1 (6.3); GII 84.6 (6.1); GIII 84.2 (7.1); GIV 88.2 (2.8). In conclusion, the dentifrices showed no lightening action on vital teeth, except for Colgate Luminous White; but according to NBS criteria, there was no noticeable visible change to the patients in any group.
RESUMO
Este estudo clínico randomizado avaliou o potencial clareador de cremes dentais disponíveis no mercado.

Materiais e Métodos:

Foram selecionados 60 pacientes, os quais foram divididos aleatoriamente em 4 grupos (n=15) GI - controle - Colgate Total 12; GII- Close-up White Now; GIII - Oral-B 3D White; GIV - Colgate Luminous White. Foram realizadas 3 escovações diárias pelo tempo de 2 a 3 minutos, durante um período de 15 dias. Os pacientes tiveram a cor de seus dentes avaliados antes e após o término do tratamento através do espectrofotômetro Vita EasyShade (escala CIE L*a*b*) Os valores de L* foram analisados por ANOVA um fator para amostras independentes e teste t para amostras pareadas. ∆E também foi calculado para verificar alterações de cor, de acordo com os critérios NBS. A média (desvio padrão) dos valores iniciais foi GI 82,9(4,9); GII 83,9(5,8); GIII 83,9(7,2); GIV 86,4(3,4); e os valores finais - GI 84,1(6,3); GII 84,6(6,1); GIII 84,2(7,1); GIV 88,2(2,8), concluindo-se que os dentifrícios analisados neste estudo não apresentaram ação clareadora sobre dentes vitais, com exceção do dentifrício Colgate Luminous White, porém de acordo com os critérios do NBS, não houve alteração visível a olho nu para nenhum dos grupos.
