Resumo: | The aim of this study was to verify the effectiveness of the ultrasound (US) in the removal of calcium hydroxide paste (CH) in simulated internal root resorption cavities (IRR). Ninety-six uniradicular, single-canal human anterior teeth were selected. The canals were prepared with a Reciproc® R50 (50 / .05), the roots were cleaved in the buccolingual direction and cavities were created with a spherical burr 5 mm from the root apex to simulate an IRR. The two halves of the root were joined with cyanoacrylate glue and the canals filled with CH paste. The irrigation protocol used to remove the paste was 3 cycles of 20 seconds of stirring 2 ml of 2.5% sodium hypochlorite, 3 cycles of 20 seconds of stirring 2 ml of 17% EDTA, followed by final washing with 10 ml of distilled water. The specimens were randomly divided into eight experimental groups (n = 12), according to the activation direction and depth of insertion of the ultrasonic insert for removing of CH paste in: MD1 - working length (WL) -1 mm mesio distal (MD) direction; BL1 - WL-1 mm in the bucco lingual (BL) direction; MD3 - WL-3 mm in the MD direction; VL3 - WL-3 mm in the VL direction; MD5 - WL-5 mm in the MD direction; VL5 - WL-5 mm in the VL direction; C + - positive control group, canal filled with CH paste; C- negative control group, canal without CH paste. All samples were submitted to the irrigation protocol except for the control groups. The roots were cleaved and optical microscopy (OM) (with 20x magnification) and scanning electron microscopy (SEM) (with 100x magnification) images were performed to evaluate the remnant of CH paste. Two calibrated examiners evaluated the images obtained following previously established scores. Data were compared using Kruskal Wallis, Mann Whitney U and Wilcoxon statistical tests, with a significance level of 5%. There was a statistically significant difference between the experimental groups and the C- group in comparison to the C+ group (p <0.05) but there was no difference between the experimental groups in the CH paste removal capacity (p> 0.05). In the comparison between the two evaluation methods, MO and SEM, there was a statistically significant difference, where the greater amount of CH remnant was observed with SEM. It can be concluded that the protocols used were effective in removing CH paste from simulated IRR. |

It can be concluded that the protocols used were effective in removing CH paste from simulated IRR.O objetivo deste estudo foi verificar a eficácia do uso do ultrassom (US) na remoção de pasta de hidróxido de cálcio (CH) em cavidades simuladas de reabsorção radicular interna (RRI). Foram selecionados 96 dentes anteriores humanos, unirradiculares e com canal único. Os canais foram preparados com instrumento Reciproc® R50 (50/.05). As raízes clivadas no sentido vestíbulo-lingual e foram criadas cavidades com ponta diamantada esférica a 5 mm do ápice radicular para simular uma RRI. As duas metades da raiz foram unidas com cola cianoacrilato e os canais preenchidos com pasta de CH. A remoção da pasta foi realizada utilizando o seguinte protocolo: 3 ciclos de 20 segundos de agitação de 2 ml de hipoclorito de sódio (NaOCl) 2,5%, 3 ciclos de 20 segundos de agitação de 2 ml de EDTA 17%, seguido de lavagem final com 10 ml de água destilada. Os espécimes foram divididos aleatoriamente em oito grupos experimentais (n=12), de acordo com o sentido de acionamento e a profundidade de inserção do inserto ultrassônico Irrisonic acoplado a aparelho ultrassônico Piezon® Master PM200 para a remoção da pasta de CH em: MD1 - comprimento de trabalho (CT) -1 mm no sentido mésio distal (MD); VL1 - CT-1 mm no sentido vestíbulo lingual (VL); MD3 - CT-3 mm no sentido MD; VL3 - CT3 mm no sentido VL; MD5 - CT-5 mm no sentido MD; VL5 - CT-5 mm no sentido VL; C+ - grupo controle positivo, canal preenchido com pasta de CH; C- - grupo controle negativo, canal sem pasta de CH. Todas as amostras foram submetidas ao protocolo de irrigação com exceção dos grupos controle. Em seguida as raízes foram novamente clivadas, e imagens foram tomadas por microscopia ótica (MO) (aumento de 20x) e microscopia eletrônica de varredura (MEV) (aumento de 100x) para avaliar o remanescente da pasta de CH. As imagens obtidas foram avaliadas por dois examinadores calibrados seguindo escores previamente estabelecidos na literatura. Os dados foram comparados utilizando os testes de Kruskal-Wallis, U de Mann-Whitney e Wilcoxon, com nível de significância de 5%. Houve diferença estatisticamente significativa entre os grupos experimentais e o grupo C- em comparação ao grupo C+ (p<0,05), entretanto não houve diferença entre os grupos experimentais e o grupo C- na capacidade de remoção da pasta de CH (p>0,05). Na comparação entre os dois métodos de avaliação, MO e MEV, houve diferença estatisticamente significativa, onde foi observada com a MEV maior quantidade de remanescente de CH. Pode-se concluir que os protocolos utilizados foram eficazes na remoção da pasta de CH de cavidades simuladas de RRI.Universidade PositivoBrasilPós-GraduaçãoPrograma de Pós-Graduação em Odontologia ClínicaUPTomazinho, Flávia Sens Fagundeshttp://lattes.cnpq.br/2908794051538663Klamas, Vanessa Cavassin2021-05-11T18:27:44Z20202021-05-11T18:27:44Z2020info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://repositorio.cruzeirodosul.edu.br/handle/123456789/2121porinfo:eu-repo/semantics/openAccessreponame:Repositório do Centro Universitário Braz Cubasinstname:Centro Universitário Braz Cubas (CUB)instacron:CUB2021-06-17T18:43:21Zoai:repositorio.cruzeirodosul.edu.br:123456789/2121Repositório InstitucionalPUBhttps://repositorio.brazcubas.edu.br/oai/requestbibli@brazcubas.edu.bropendoar:2021-06-17T18:43:21Repositório do Centro Universitário Braz Cubas - Centro Universitário Braz Cubas (CUB)false |
