Abstract
IntroductionEsthetics, being the major concern of today’s treatments, has led to numerous innovations, including composites, for different treatment options. Esthetic orthodontics requires the use of composites for bonding orthodontic brackets to the teeth.AimsTo identify which combination of composites has the highest shear bond strength at the tooth-bracket interface.Materials and methodsThree different composite kits were selected for each group (n=42) and were further divided into three subgroups (n=14), where the bonding agents and/or primer were interchanged to find the best combination.ResultsSub-group B2 (Orthofix + Eazetch + Universal Bond) showed the highest shear bond strength (10.74 ± 3.45 MPa), which was highly significant at p =/<0.0001.ConclusionThe highest shear bond strength was found with the combination of 37% phosphoric acid (Eazetch), GC Universal Bond (GC Corporation, Tokyo, Japan), and Orthofix composite material (Anabond Stedman, Chennai, India). As this study is an in-vitro study, we need longitudinal in-vivo studies to establish the best combination for the bonding of orthodontic brackets.

Premolars extracted for orthodontic purposes were collected and a shear bond strength test was performed with an Instron Universal Testing machine (Instron, MA, US) at Gitam’s College of Engineering, Visakhapatnam
Along with the shear bond strength tests, adhesive remnants were recorded based on the amount of adhesive that remained on the tooth surface after debonding with 10x magnification and 40x magnification and the values were analyzed with the one-way analysis of variance (ANOVA) statistical test
Summary
The highest shear bond strength was found with the combination of 37% phosphoric acid (Eazetch), GC Universal Bond (GC Corporation, Tokyo, Japan), and Orthofix composite material (Anabond Stedman, Chennai, India). Categories: Miscellaneous, Other Keywords: shear bond strength, orthodontic brackets, composites, etchants. Composites work wonders in young children and adolescents where esthetics and social acceptability are prime concerns. They have become the most accepted and widely used material by dentists performing orthodontic treatments all over the world. Numerous studies have been conducted considering different materials under various conditions for orthodontic shear bond strength. The.
