Abstrakt: Objective: The purpose of this study was to evaluate the in vitro shearing force performance of orthodontic attachments using two self-etching primers (SEPs): iBOND and G-Bond. Design: In vitro, laboratory study. Material and methods: One hundred and eighty human molars were randomly divided into four groups and again into three sub-groups with 15 teeth each. Teeth were bonded with a stainless steel button (GAC International, Bohemia, NY, USA) using Transbond XT adhesive composite. The bonding agents were iBOND, G-Bond, Transbond Plus SEP and Transbond XT primer. Shearing force tests were carried out immediately, and at 24 hours and 3 months using a universal testing machine. Force to debond (N) and Adhesive Remnant Index (ART) scores were evaluated and compared. Results: Transbond XT primer required a higher immediate (P
