| Popis: | Objective: To compare the bond strength and failure mode between total and self-etching systems used for brackets cementation.Methods: Twenty human first premolars were randomly divided into two groups: 10 for the total etching system (Transbond™ XT, 3M Unitek, St. Paul, Minnesota, USA) and 10 for the self-etching system (Transbond™ Plus Self Etching Primer + Transbond™ XT, 3M Unitek, St. Paul, Minnesota, USA). Standard brackets (Ortho Organizers, California, USA) were cemented, and after 24 hours submitted to 5000 thermal cycles. Subsequently, shear bond strength tests were performed applying force at the bracket/enamel interphase using an universal testing machine (Instron®) at 1.5 mm/min crosshead speed. Finally, enamel surfaces and bracket bases were observed using a stereomicroscope (Stemi 2000C, Carl Zeiss, Göttingen, Germany).Results: The results, in terms of bond strength, showed a statistical significant difference (p |
