Effect of chlorhexidine incorporation on the mechanical properties of acrylic reline resinsSaúde oralPróteseTeses de mestrado - 2015Domínio/Área Científica::Ciências Médicas::Medicina ClínicaTese de mestrado, Medicina Dentária, Universidade Lisboa, Faculdade de Medicina Dentária, 2015The main goal of this study was to evaluate the effect of chlorhexidine incorporation on the microhardness and flexural strength of three acrylic reline resins, Kooliner, Ufi Gel Hard and Probase Cold. For each material there were five groups, with different chlorhexidine concentrations (n=8), being the control group the one with 0% chlorhexidine. The other concentrations studied were 1%, 2.5%, 5% and 7.5%. Specimens with 64x10x3.3mm, were tested for Knoop hardness and flexural strength values. Data were submitted to nonparametric tests according to the Kruskal-Wallis (p<0.05). Concerning the effects of the reline resin on microhardness, comparing all three materials led to the conclusion that microhardness values showed differences between groups, having Probase Cold the higher values, followed by Ufi Gel and Kooliner. In terms of effects of different chlorhexidine concentrations incorporation on the resins, there were differences between groups on Kooliner and Ufi Gel specimens. No statistically significant differences were found for Probase Cold, between groups of chlorhexidine. Relatively to effects of the reline resin on flexural strenght, comparing all three materials, there were differences between groups, with Probase Cold showing higher values than the other two materials. Regarding the effect of incorporation of different concentrations of chlorhexidine on flexural strenght, Kooliner groups didn’t show differences between them as well as Ufi Gel. Concerning Probase specimens, there were differences between groups that showed that 7.5% chlorhexidine group had lower values than control and 1% chlorhexidine group. Globally, it was possible to determine some important aspects of the effects of incorporation of different concentrations of chlorhexidine on the mechanical properties of acrylic reline resins.Neves, Cristina BettencourtPortugal, Jaime, 1969-Repositório da Universidade de LisboaMartins, Sérgio Abreu Lacerda2017-01-11T11:53:40Z201520152015-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/25832TID:201273349enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:15:33Zoai:repositorio.ul.pt:10451/25832Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:42:36.751638Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
