Resumo: | Objective: to evaluate the effectiveness of 38% hydrogen peroxide in teeth whitening with orthodontic appliances. Materials and methods: Forty specimens were made in the form of a bovine enamel/dentin block (9mm x 2mm), with 1mm of enamel and 1mm of dentin, were obtained. After embedding the specimen in acrylic resin, they were divided into 4 groups (n=10): Group 1: Negative Control, the specimen did not receive any treatment; Group 2: Only orthodontic brackets were bonded, without bleaching; Group 3: Orthodontic brackets and PH38%; Group 4: Positive control, submitted to bleaching treatment with PH38%, without brackets. The bleaching agent was applied once a week for 45 minutes for 4 weeks. The color was measured before placing the brackets and 7 days after bleaching using the L*a*b* coordinates of the CIE-Lab system, with a spectrophotometer. ΔE values were statistically analyzed by ANOVA and Games-Howell tests (p<0.05). As for the L* and a* coordinates, the ANOVA, Student's T, and Games-Howell post hoc tests were used (p<0.05); in the b* coordinate, ANOVA, Student's T and Tukey's post hoc tests were performed (p<0.05). Results: In ΔE, groups G3 and G4 were statistically like each other. In relation to the coordinates of L* and b*, the groups G3 and G4 presented different values from each other, with G4 showing the highest averages; on the other hand, the a* coordinate presented the highest values for G3. Conclusion: bleaching with PH38% was effective in teeth with orthodontic appliances. |

Materiales y métodos: Se obtuvieron cuarenta especímenes en forma de bloque de esmalte/dentina bovina (9mm x 2mm), con 1mm de esmalte y 1mm de dentina. Después de embeber el espécimen en resina acrílica, se dividieron en 4 grupos (n=10): Grupo 1: Control Negativo, el espécimen no recibió ningún tratamiento; Grupo 2: Solo se cementaron brackets de ortodoncia, sin blanqueamiento; Grupo 3: Brackets de ortodoncia y PH38%; Grupo 4: Control positivo, sometido a tratamiento de decoloración con PH38%, sin brackets. El agente blanqueador se aplicó una vez por semana durante 45 minutos durante 4 semanas. El color se midió antes de colocar los brackets y 7 días después de la decoloración utilizando las coordenadas L*a*b* del sistema CIE-Lab, con un espectrofotómetro. Los valores de ΔE fueron analizados estadísticamente por ANOVA y pruebas de Games-Howell (p<0.05). En cuanto a las coordenadas L* y a*, se utilizaron las pruebas post hoc ANOVA, T de Student y Games-Howell (p<0,05); en la coordenada b* se realizaron las pruebas ANOVA, T de Student y post hoc de Tukey (p<0.05). Resultados: En ΔE, los grupos G3 y G4 fueron estadísticamente similares entre sí. En relación a las coordenadas de L* y b*, los grupos G3 y G4 presentaron valores diferentes entre sí, siendo G4 el que presentó los promedios más altos; por otro lado, la coordenada a* presentó los valores más altos para G3. Conclusión: el blanqueamiento con PH 38% fue efectivo en dientes con aparatos de ortodoncia.Objetivo: avaliar a efetividade do peróxido de hidrogênio a 38% no clareamento de dentes com aparatologia ortodôntica. Materiais e métodos: Foram confeccionados quarenta espécimes em forma de bloco de esmalte/dentina bovinos (9mm x 2mm), com 1mm de esmalte e 1mm de dentina. Após o embutimento do espécime em resina acrílica, os mesmos foram divididos em 4 grupos (n=10): Grupo 1: Controle Negativo, o espécime não recebeu nenhum tratamento; Grupo 2: Colados bráquetes ortodônticos, sem clareamento; Grupo 3: Bráquetes ortodônticos e PH38%; Grupo 4: Controle positivo, submetido ao tratamento clareador com PH38%, sem bráquetes. O agente clareador foi aplicado 1 vez por semana, por 45min, durante 4 semanas. A cor foi mensurada antes da colocação dos bráquetes e após 7 dias do clareamento pelas coordenadas L*a*b* do sistema CIE-Lab, com um espectrofotômetro. Os valores do ΔE foram analisados estatisticamente pelos testes ANOVA e Games-Howell (p<0,05). Já as coordenadas L* e a*, utilizados os testes ANOVA, T de Student’s, post hoc de Games-Howell (p<0,05); na coordenada b*, realizados os testes ANOVA, T de Student’s e post hoc de Tukey (p<0,05). Resultados: No ΔE, os grupos G3 e G4 foram estatisticamente semelhantes entre si. Já em relação as coordenadas de L* e b*, os grupos G3 e G4 apresentaram valores diferentes entre si, sendo que o G4 apontou as maiores médias; em contrapartida, a coordenada a* apresentou os maiores valores para o G3.
