Resumo: The objective of this in vitro study was to assess and compare the shear bond strength of conventional and modified orthodontic tubes bonded to the surface of dry and saliva-contaminated enamel. The sample consisted of 40 human teeth, which were randomly divided into four groups according to attachment base and presence or absence of saliva contamination as follows: Group CB, conventional orthodontic tubes without salivary contamination; Group CB-S, conventional orthodontic tubes with salivary contamination; Groups BM, orthodontic tubes modified by welding a metal mesh to their base without salivary contamination; and Group BM-S,  modified orthodontic tubes with salivary contamination. Shear bond strength test was performed in a universal testing machine and analysis of the adhesive remnant index (ARI) by optical microscopy. Two-way ANOVA was used, followed by Tukey’s test at a statistical significance level of 5%. The ARI results were analysed descriptively. There was statistically significant difference between the groups regarding the shear bond strength values, with conventional tubes presenting significantly higher values (P < 0.05). In addition, the presence of salivary contamination interfered negatively with the behaviour of conventional tubes only (P < 0.05). Shear bond strength was not improved by increasing the area of the orthodontic tubes. Moreover, salivary contamination influenced negatively the SBS values, but only when conventional tubes were used.

A amostra foi composta por 40 molares humanos, os quais foram divididos aleatoriamente em quatro grupos, de acordo com a base de colagem e a presença ou não de contaminação salivar: no grupo BC foram utilizados os tubos ortodônticos com base convencional e sem contaminação salivar, ao grupo BC-S foi adicionada a simulação da contaminação salivar, no grupo BM foram utilizados tubos ortodônticos modificados pela inclusão de malha metálica soldada em sua base e sem contaminação salivar, e ao grupo BM-S foi adicionada a presença da contaminação salivar. O teste de resistência de união ao cisalhamento (Ru) foi realizado em máquina de ensaios mecânicos universal e a análise do índice de remanescente adesivo (IRA) por meio de Microscopia Óptica. Para análise dos dados de Ru foi utilizada Análise de Variância a dois critérios (ANOVA), seguido do Teste de Tukey, ao nível de significância estatística de 5%. Os resultados do IRA foram analisados descritivamente. Houve diferença estatisticamente significante entre os grupos quanto à Ru (p<0,05). A presença de contaminação salivar interferiu negativamente apenas no comportamento dos tubos convencionais (p<0,05). Os valores de resistência de união ao cisalhamento não aumentaram em função do aumento da área dos tubos ortodônticos. Com relação à contaminação salivar, esta influenciou negativamente os valores de Ru apenas quando foram utilizados tubos convencionais.Editora Uningá2021-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfapplication/pdfhttps://revista.uninga.br/uninga/article/view/365710.46311/2318-0579.58.eUJ3657Revista Uningá; Vol. 58 (2021); eUJ3657Revista Uningá; v. 58 (2021); eUJ36572318-057910.46311/ru.v58i0reponame:Revista Uningá (Online)instname:Centro Universitário Uningáinstacron:UNINGAporenghttps://revista.uninga.br/uninga/article/view/3657/2447https://revista.uninga.br/uninga/article/view/3657/244910.46311/ru.v58i0.3657.g244710.46311/ru.v58i0.3657.g2449Copyright (c) 2021 UNINGÁ JOURNALhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBrandão, GermanoMaltagliati, Liliana ÁvilaNahás-Scocate, Ana Carla RaphaelliMatias, MuriloBordin, DimorvanRoscoe, Marina GuimarãesPatel, Mayara Paim2023-10-20T18:43:58Zoai:ojs.revista.uninga.br:article/3657Revistahttps://revista.uninga.br/uninga/indexPUBhttps://revista.uninga.br/uninga/oairevistauninga@uninga.edu.br2318-05792318-0579opendoar:2023-10-20T18:43:58Revista Uningá (Online) - Centro Universitário Uningáfalse
