Resumo: This study aimed to verify the effect of light and heat on bleaching action of 40% hydrogen peroxide (Opalescence Boost PF – Ultradent, BR). Thirty-three bovine incisors were submitted to in-office dental bleaching and divided into three groups (n=11): CO group – control, no light or heat; CA group – heat with a hairdryer; LC group – light and heat with a photoactivation device. For this, a gingival barrier (OpalDam – Ultradent, SP, BR) isolated a circular area around the flatter region of the crown. Afterwards, the bleaching gel was applied for 15 minutes and repeated twice, totaling 45 minutes of application. For the CA and LC groups, the heat source was maintained during the application of the bleaching gel. Temperature was standardized in 5°C for both groups and monitored using a thermocouple inserted into the pulp chamber. The color measurement was performed before and after bleaching using a spectrophotometer. The inner margin of the isolated area of each dental crown was equivalent to the tip of the spectrophotometer (4 mm). Color change was verified by CIEDE2000 system (ΔE00). One way ANOVA and Tukey's test were used to analyze data (p-values set to 5%). The values of ΔE00 were equal for LC (2,66±0,29) and CA (2,44±0,88), and both were higher than CO (1,31±0,37). Therefore, light does not play a fundamental role for in-office dental bleaching. Same dental bleaching outcomes are obtained using different heat sources.

Treinta y tres incisivos bovinos fueron sometidos a blanqueamiento dental en el consultorio y se dividieron en tres grupos (n = 11): grupo de CO - control, sin luz ni calor; Grupo CA - calentar con secador de pelo; Grupo LC: luz y calor con un dispositivo de fotoactivación. Una barrera gingival (OpalDam - Ultradent, SP, BR) fue aplicada para aislar un área circular alrededor de la región más plana de la corona. Posteriormente se aplicó el gel blanqueador durante 15 minutos y se repitió dos veces, totalizando 45 minutos de aplicación. Para los grupos CA y LC, la fuente de calor se mantuvo durante la aplicación del gel blanqueador. La temperatura se estandarizó em 5°C para ambos grupos y se controló mediante un termopar insertado en la cámara pulpar. La medición del color se realizó antes y después del blanqueo usando un espectrofotómetro. El margen interno del área aislada de cada corona dental fue equivalente a la punta del espectrofotómetro (4 mm). El cambio de color fue verificado por el sistema CIEDE2000 (ΔE00). Se utilizaron ANOVA de una forma y la prueba de Tukey para analizar los datos (valores de p establecidos en 5%). Los valores de ΔE00 fueron iguales para LC (2,66 ± 0,29) y CA (2,44 ± 0,88), y ambos fueron superiores a CO (1,31 ± 0,37). Por tanto, la luz no juega un papel fundamental para el blanqueamiento dental en consultorio. Se obtienen los mismos resultados de blanqueamiento dental utilizando diferentes fuentes de calor.O objetivo neste trabalho foi verificar o efeito da luz e do calor na ação clareadora do peróxido de hidrogênio 40% (Opalescence Boost PF – Ultradent, BR). Trinta e três incisivos bovinos foram submetidos ao clareamento de consultório e divididos em três grupos: Grupo CO – controle, sem luz e sem calor; Grupo CA – calor do secador de cabelo; Grupo LC – luz e calor com fotoativador. Para isso, uma barreira gingival (OpalDam – Ultradent, SP, BR) foi utilizada para isolar uma área circular ao redor da região mais plana da coroa. Após, o gel clareador foi aplicado por 15 minutos e repetido duas vezes, totalizando 45 minutos de aplicação. Para os grupos CA e LC, a fonte de calor foi mantida durante a aplicação do gel clareador. A temperatura foi padronizada em 5°C para ambos os grupos e monitorada por meio de um termopar inserido na câmara pulpar. A cor das amostras foi aferida antes e após o procedimento clareador, por meio de um espectrofotômetro. A margem interna da área isolada de cada coroa dental era equivalente à ponta do espectofotometro (4 mm). A alteração de cor foi verificada por meio do sistema CIEDE2000 (ΔE00). Os resultados foram estatisticamente analisados por ANOVA 1-fator e teste post-hoc de Tukey (nível de significância de 5%). Os valores de ΔE00 de LC (2,66±0,29) e CA (2,44±0,88) foram maiores que CO (1,31±0,37). Portanto, conclui-se que a luz não desempenha um papel fundamental no processo de clareamento de consultório, sendo possível obter os mesmos resultados somente com fonte de calor.Research, Society and Development2021-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2081310.33448/rsd-v10i13.20813Research, Society and Development; Vol. 10 No. 13; e10101320813Research, Society and Development; Vol. 10 Núm. 13; e10101320813Research, Society and Development; v. 10 n. 13; e101013208132525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/20813/19270Copyright (c) 2021 May Anny Alves Fraga; João Pedro Castello Marcatto; Talita Malini Carletti; Lourenço Correr-Sobrinho ; Américo Bortolazzo Correrhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFraga, May Anny AlvesMarcatto, João Pedro Castello Carletti, Talita MaliniCorrer-Sobrinho , LourençoCorrer, Américo Bortolazzo2021-11-21T18:26:28Zoai:ojs.pkp.sfu.ca:article/20813Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:21.258412Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
