Comparison Of Shear Bond Strength And Adhesive Remnant Index Between Different Adhesive Systems In Bonding and Rebonding of Orthodontic Brackets

Aim: The aim of this study was to compare the shear bond strength (SBS) and adhesive remnant index of stainless-steel brackets bonded with different orthodontic adhesive systems. Materials and Methods: In our study performed on 60 premolar teeth extracted for orthodontic reasons, MBT prescription 0.022'' stainless-steel brackets (Discovery Smart®, Dentaurum, Germany) were used. In teeth randomly divided into 3 groups, bonding was performed with Group 1: Trulock Light Activated Bonding System (RMO, USA), Group 2: Bisco Ortho Bracket Paste LC (Bisco, USA), Group 3: Transbond XT Light Cure Adhesive (3M, USA). SBS and residual adhesive indexes (ARI) were evaluated by breaking the samples. Adhesive residues were cleaned with tungsten carbide burs from the surfaces of the teeth, rebonding was made after sanding the brackets’ surfaces. SBS and ARI values were re-evaluated. One-way ANOVA, two-sample t-test and Mann-Whitney U tests were used for statistical analysis of the data, p
