The main purpose of this study was to evaluate the effect of chlorhexidine incorporation on shear bond strength and surface free energy of three acrylic reline resins, Kooliner, Ufi Gel Hard and Probase Cold. For all tests, the experimental specimens were incorporated with chlorhexidine 1%, 2.5%, 5%, 7.5% or 10% (w/w) and the control specimens were left unloaded. Shear bond strength test was performed on specimens of reline resins attached to denture base resin (n=10) and after this test, the failure mode was assessed. Specimens with 25×16×1 mm dimensions (n=5) were submitted to contact angles determination, performed by the Wilhelmy plaque technique, in order to estimate surface free energy values. Statistical differences were observed among acrylic reline resins in shear bond strength values, with Kooliner showing significantly lower values than the other reline resins. Statistical differences weren’t found between groups from Kooliner and Ufi Gel Hard. Probase Cold specimens obtained a decrease of shear bond strength values with the increase of chlorhexidine concentration incorporated. Statistical differences were observed among acrylic reline resins in total surface free energy values, with Ufi Gel Hard demonstrating total surface free energy values significantly higher than the other reline resins, at cost of the increased values of dispersive component. Statistical differences were found between all groups in total surface free energy values from Kooliner, Ufi Gel Hard and Probase Cold. However, only Kooliner showed significant differences in dispersive and polar components. In sum, the incorporation of chlorhexidine has influence only on shear bond strength of Probase Cold specimens with higher concentrations of chlorhexidine. The surface free energy of the three acrylic reline resins is affected by the incorporation of chlorhexidine.Neves, Maria Cristina Bettencourt, 1976-Bettencourt, Ana FranciscaRepositório da Universidade de LisboaBarreiros, Marta Cristina Silvério2016-12-29T11:26:39Z201520152015-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/25528TID:201272814enginfo: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:RCAAP2023-11-08T16:15:05Zoai:repositorio.ul.pt:10451/25528Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:42:24.583931Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
