Resumo: | The objective of this research was to verify the degree of marginal infiltration in class-V, vestibular, and lingual cavities in 40 recently-extracted human premolar teeth, divided into four groups, which, after the thermal cycle at 5ºC/55ºC, and stained with 2% methylene blue, were assessed in two ways: 1 - types of composite resin: microparticles (Silux Plus - 3M), microhybrid (Z 250 - 3M) and nanohybrid (Grandio - VOCO); and 2 - location of the cavity wall (occlusal enamel wall and gingival cement wall). The data were measured through scores of 0 to 4 and statistically analyzed by nonparametric Kruskal-Wallis test in order to demonstrate the composite resin and cavity wall that allowed less dye leakage. The three types of composite resin - microparticles, microhybrid, and nanohybrid - showed no statistically significant difference between them; nanohybrid resin showed the lowest scores of dye penetration. There was no statistically significant difference between the occlusal enamel wall and the gingival cement wall. However, the occlusal enamel wall was the one with the lowest scores of dye penetration. |

Os dados foram mensurados por meio de escores de 0 a 4 e processados estatisticamente pelo teste não paramétrico de Kruskal-Wallis, a fim de demonstrar a resina composta e a parede cavitária que menos permitiu a infiltração do corante. Os três tipos de resina composta – micropartícula, microhíbrida e nanohíbrida – não mostraram diferença estatística significante entre si; a resina nanohíbrida foi a que apresentou os menores escores de infiltração do corante. Também não houve diferença estatística significante entre a parede oclusal em esmalte e gengival em cemento; todavia, a parede oclusal em esmalte foi a que apresentou os menores escores de infiltração do corante.Universidade Metodista de PiracicabaNunes, Osvaldo Benoni da CunhaRamalho, Humberto de SousaNunes, Nancy AlfieriAbreu, Paulo Humaitá de2011-02-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/article/view/5710.15600/2238-1236/fol.v21n1p25-38Revista da Faculdade de Odontologia de Lins; v. 21, n. 1 (2009): Revista da Faculdade de Odontologia de Lins; 25-382238-123601047582reponame:Revista da Faculdade de Odontologia de Lins (Online)instname:Universidade Metodista de Piracicaba (UNIMEP)instacron:UNIMEPporhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/article/view/57/22info:eu-repo/semantics/openAccess2016-06-01T13:27:27Zoai:ojs-unimep.metodista.br:article/57Revistahttps://www.metodista.br/revistas/revistas-unimep/index.php/Folhttps://www.metodista.br/revistas/revistas-unimep/index.php/Fol/oai||revistafol@unimep.br|| nalfieri@unimep.br2238-12360104-7582opendoar:2016-06-01T13:27:27Revista da Faculdade de Odontologia de Lins (Online) - Universidade Metodista de Piracicaba (UNIMEP)false |
