Resumo: | The aim of this study was to evaluate different post lengths and adhesive strategies for restoring extensively damaged canines. Sixty human canines were randomly distributed into two groups (n=30), according to the resin cement used: self-adhesive or conventional. Each group was further distributed into 3 groups (n=10) based on the intracanal post lengths: 5, 7.5 and 10 mm. The radicular portion was endodontically filled, the cervical third was enlarged to simulate extensive damage and the coronal portion was reconstructed with composite resin. The samples were prepared with a simulated periodontal ligament and submitted to fatigue loading (160N – 1,200,000 cycles), followed by fracture resistance testing. The results were submitted to two-way ANOVA and Tukey tests (α=5%). The assessed glass fiber post lengths have not influenced on the fracture resistance (p>0.05). However, the performance of the conventional cements was better than the self-adhesive cements when the same post length was compared (p<0.05). Repairable fractures were prevalent (70-90%) in all groups tested. Conventional resin cement yielded higher fracture resistance than self-adhesive cement, regardless the post length adopted. |

Sesenta caninos humanos fueron divididos al azar en dos grupos (n=30), según el cemento de resina utilizado: convencional o autoadhesivo. Cada grupo se dividió en 3 grupos (n=10) según la longitud de los postes: 5, 7.5 e 10mm. La porción radicular fue tratada endodônticamente, se amplió el tercio cervical simulando una fractura extensa y se reconstruyó la porción coronal con resina compuesta. Las muestras se prepararon con un ligamento periodontal experimental y se sometieron a una prueba de fatiga (160N – 1.200.000 ciclos), seguido de una prueba de resistencia a la fractura. Los resultados fueron sometidos a las pruebas ANOVA y Tukey (α=5%). Las longitudes de los postes de fibra de vidrio ensayados no influyeron en la resistencia a la fractura (p<0,05). Sin embargo, el desempeño de los cementos convencionales fue mejor que el de los cementos autoadhesivos al comparar postes de la misma longitud (p<0,05), siendo prevalentes las fracturas reparables (70-90%) en todos los grupos evaluados. Los cementos de resina convencionales proporcionaron mayor resistencia a la fractura que los autoadhesivos, independientemente de la longitud del poste utilizado.O objetivo deste trabalho foi avaliar diferentes comprimentos de pinos de fibra de vidro e estratégias adesivas para restaurar caninos com fraturas extensas. Sessenta caninos humanos foram aleatóriamente divididos em dois grupos (n=30), de acordo com o cimento resinoso utilizado: autoadesivo ou convencional. Cada grupo foi então dividido em 3 grupos (n=10) de acordo com os comprimentos dos pinos: 5, 7.5 e 10mm. A porção radicular foi tratada endodônticamente, o terço cervical foi alargado simulando fratura extensa e a porção coronária foi reconstruida com resina composta. As amostras foram preparadas com um ligamento periodontal experimental e submetidas a teste de fadiga (160N – 1.200.000 ciclos), seguido de teste de resistência a fratura. Os resultados foram submetidos aos testes de ANOVA e Tukey (α=5%). Os comprimentos dos pinos de fibra de vidro testados não influenciaram a resistência a fratura (p<0.05). Entretanto a performance dos cimentos convencionais foi melhor do que a dos cimentos autoadesivos quando comparados pinos de mesmo comprimento (p<0.05) Fraturas reparáveis foram prevalentes (70-90%) em todos os grupos testados. Cimentos resinosos convencionais forneceram maior resistência a fratura do que os autoadesivos, independente do comprimento do pino utilizado.Research, Society and Development2022-03-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2586810.33448/rsd-v11i3.25868Research, Society and Development; Vol. 11 No. 3; e19411325868Research, Society and Development; Vol. 11 Núm. 3; e19411325868Research, Society and Development; v. 11 n. 3; e194113258682525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25868/23552Copyright (c) 2022 Oscar João Klüppel Neto; Kaye Varaschin Theodorovicz; Aline Akemi Mori; Gabriela Cristina Santin; Fernanda Ferruzzi Lima; Rafael Rocha Pacheco; Daniel Sundfeld; Núbia Inocêncya Pavesi Pinihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKlüppel Neto, Oscar JoãoTheodorovicz, Kaye Varaschin Mori, Aline AkemiSantin, Gabriela CristinaLima, Fernanda Ferruzzi Pacheco, Rafael Rocha Sundfeld, DanielPini, Núbia Inocêncya Pavesi 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/25868Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:02.903626Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
