Methods: Distinct proportions of CHX were selected for loading each reline resin. Kooliner had four groups (1%, 2.5%, 5%, 7.5% CHX), Ufi Gel Hard had five groups (1%, 2.5%, 5%, 7.5%, 10% CHX) and Probase Cold had three groups (1%, 2.5%, 5% CHX). Every material had also a control group (0% CHX). Specimens with 64x10x3.3mm were submitted to a thermocycling procedure consisting of 1000 cycles of thermal fluctuations between 5ºC and 55ºC. Afterwards they were tested for flexural strength values using a three point bending device. Results were submitted to nonparametric tests according to the Kruskal-Wallis method, followed by multiple comparisons using Mann-Whitney tests with Bonferroni corrections, being considered the 5% level of significance (α=0.05). Results: Regarding Kooliner and Ufi Gel Hard specimens, there were no statistical significant differences on flexural strength values among different CHX groups (p>0.05). Results for Probase Cold specimens showed that 5% CHX group had a lower flexural strength value compared to the control group (p= 0.033). Conclusions: The proportions of 1%, 2.5%, 5% and 7.5% CHX for Kooliner, 1%, 2.5%, 5%, 7.5% and 10% CHX for Ufi Gel Hard and 1% and 2.5% CHX for Probase Cold do not affect the flexural strength values of the acrylic resins after a thermal ageing process equivalent to one month in the oral cavity.Neves, Maria Cristina Bettencourt, 1976-Portugal, Jaime, 1969-Repositório da Universidade de LisboaRijo, Inês Costa2018-11-26T09:30:33Z20182018-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/35458TID:201983850enginfo: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:RCAAP2023-11-08T16:31:23Zoai:repositorio.ul.pt:10451/35458Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:49:53.601961Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
