Resumo: | Objective: The aim of this study was to evaluate the color stability of dental enamel exposed to cigarette smoke after orthodontic debonding. Methods: Thirty-two bovine incisors were allocated into control (C1 and C2) and experimental groups (n=8) according to distinct bonding protocols: with adhesive (B1) and without adhesive (B2) and exposure to cigarette smoke. Samples from B1, B2 and C2 were exposed to ten cycles of smoke in a specific and hermetic chamber while the C1 remained stored in artificial saliva. Color analysis was performed with a spectrophotometer according to the L*a*b* system. Intergroup comparisons and effect of time were estimated with ANOVA/Tukey and paired Student t tests, respectively (a=0.05). Results: Statistically significant color changes have not been observed in C1 (L*: -0.69 ± 0.80; a*: 0.36 ± 0.23; b*: 0.17 ± 0.50) and without adhesive (B2) (L*: -3.74 ± 2.85; a*: 0.93 ± 0,73; b*: 1.13 ± 1.16) through the study time (p>0,05). However, the group with adhesive (B1) presented significant color changes in L*:-5.55 ± 2.28, a*: 2.33 ± 0.77 and b*: 3.30 ± 1.37, what means, darker, greener and more yellow, respectively (p<0,05) and the control group that was exposed to the cigarette smoke (C2) presented significant color changes in L*: -1.72 ± 0.28 e b*: 1.82 ± 0.22, what means, darker and more yellow, respectively. Conclusion: Enamel color stability was affected by exposure to cigarette smoke after orthodontic debonding, especially when bonding protocolcomprised the application of primer adhesive. |

Objetivo: O objetivo deste estudo foi avaliar a estabilidade da cor do esmalte dentário exposto à fumaça de cigarro após a descolagem ortodôntica. Métodos: Trinta e dois incisivos bovinos foram alocados nos grupos controle (C1 and C2) e experimental (n = 8) de acordo com protocolos de colagem ortodôntica distintos: com adesivo (B1) e sem adesivo (B2) e expostos à fumaça de cigarro. Amostras do B1, B2 e C2 foram expostas a dez ciclos de fumaça em uma câmara específica e hermética, enquanto o C1 permaneceu armazenado em saliva artificial. A análise da estabilidade de cor foi realizada com um espectrofotômetro de acordo com osistema L* a* b*. As comparações intergrupos e o efeito do tempo foram verificados com ANOVA / Tukey e testes t de Student, respectivamente (a=0,05). Resultados: Não foram observadas alterações de cor estatisticamente significativas no C1 (L*: -0,69 ± 0,80; a*: 0,36 ± 0,23; b*: 0,17 ± 0.50) e sem adesivo (B2) (L*: -3,74 ± 2,85; a*: 0,93 ± 0,73; b *: 1,13 ± 1,16) durante o tempo de estudo (p>0,05). No entanto, o grupo com adesivo (B1) apresentou alterações significativas de cor em L*: - 5,55 ± 2,28, a*: 2,33 ± 0,77 eb*: 3,30 ± 1,37, o que significa, mais escuro, mais verde e mais amarelo, respectivamente (p<0,05) e o grupo controle exposto à fumaça de cigarro (C2) apresentou alterações significativas de cor em L*: -1,72 ± 0,28 e b*: 1, 82 ± 0,22, o que significa, mais escuro e mais amarelo, respectivamente. Conclusão: A estabilidade da cor do esmalte foi afetada pela exposição à fumaça de cigarro após a descolagem ortodôntica, principalmente quando o protocolo de colagem incluía a aplicação de adesivo.Rio de Janeiro Dental Journal2021-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cro-rj.org.br/revcientifica/index.php/revista/article/view/15910.29327/24816.5.2-6Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); Vol. 5 No. 2: May-August 2020; 50-55Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); v. 5 n. 2: May-August 2020; 50-552595-47331518-524910.29327/24816.5.2reponame:Revista Científica do CRO-RJ (Online)instname:Conselho Regional de Odontologia do Rio de Janeiro (CRO-RJ)instacron:CROporhttps://cro-rj.org.br/revcientifica/index.php/revista/article/view/159/107Copyright (c) 2021 Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal)info:eu-repo/semantics/openAccessCopello, Flávio MendonçaRamos Losso, AndréGalisteu Luiz, KellyFerreira Lira, LarineCastro, Amanda Cunha Regal deAraujo, Mônica Tirre de Souza2021-11-30T18:22:18Zoai:ojs3.cro-rj.org.br:article/159Revistahttps://cro-rj.org.br/revcientifica/index.php/revistahttps://cro-rj.org.br/revcientifica/index.php/revista/oairevista.cientifica@cro-rj.org.br || rorefa@terra.com.br2595-47331518-5249opendoar:2021-11-30T18:22:18Revista Científica do CRO-RJ (Online) - Conselho Regional de Odontologia do Rio de Janeiro (CRO-RJ)false |
