The null hypothesis tested was that the bonding effectiveness to dentin was not affected when the adhesive was applied either following an etch-and-rinse or etch-and-dry technique. Methods: Six recently extracted human third molars, intact and without macroscopic evidence of caries or restorations, were assigned to two groups according to the etching strategy: Group SBU TE D – Scotchbond Universal Adhesive (3M ESPE) applied as a 2-step etch-and-rinse adhesive on moist dentin; Group SBU SE D - Scotchbond Universal Adhesive applied as a 1-step self-etch adhesive on dentin. After resin composite build-ups were performed, the teeth were stored in distilled water in an incubator for 24 hours at 37°C. Specimens were sectioned with a slow-speed diamond saw under water irrigation to obtain bonded sticks that were tested to failure in a universal testing machine at a crosshead speed of 1mm/minute. The statistical analysis of the results was performed with SPSS. A paired-sample t-test was performed when the assumption of normality was valid. Results: The mean μTBS to dentin of the Scotchbond Universal Adhesive applied following the etch-and-dry approach (SBU SE D) was statistically higher than that when the SBU was applied following the etch-and-rinse approach (SBU TE D) (p = 0,008). Conclusions: Within the limitations of the present laboratory study, it may be concluded that improved bonding effectiveness of SBU on dentin is obtained when the adhesive is applied with the self-etch approach. The etch-and-rinse approach tested (wet dentin) resulted in immediate bond strength statistically lower than the self-etch group.Pequeno, AnaCoito, Ana CatarinaRepositório da Universidade de LisboaFernandes, Sara Palmares2016-12-28T16:33:03Z201420142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/25493TID:201268647enginfo: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:RCAAP2023-11-08T16:14:50Zoai:repositorio.ul.pt:10451/25493Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:42:18.547697Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
