“…In the literature, eight RCTs evaluated the UA Scotchbond Universal in SE and ER modes at different recalls (6 to 36 months) [ 2 , 15 , 17 , 19 , 22 , 25 , 26 , 34 ]. Other RCTs tested the UAs Xeno Select [ 24 ], FBU [ 12 , 18 ], Prime & Bond Elect [ 14 ], Tetric N-Bond Universal (ADU in some countries) [ 12 , 33 ], Gluma Universal [ 21 ], ClearfilT Universal Bond, iBond Universal, and G-Premio BondTM [ 20 ], with 6- to 24-month recalls. Our RCT, after the 1-year recall [ 23 ], assessed and compared the performance of two UAs—FBU and ADU—from different manufacturers.…”
