The Performance of Universal Adhesives on Orthodontic Bracket Bonding

Abstract Objective This article aimed to assess the effects of double application universal adhesives on shear bond strength orthodontic brackets. Materials and Method Seventy-five extracted human premolars were used. The teeth randomly assigned into five groups based adhesive procedure (n = 15). Scotchbond Universal (3M Oral Care) Prime&Bond (Dentsply) used (following manufacturer’s instructions application). Transbond XT Primer Unitek) was employed as control. Following application, brackets bonded tooth surfaces. After storage in distilled water for 24 hours at 37°C, specimens subjugated test under a testing machine (Autograph AGS-X; Shimadzu). Data analyzed with one-way analysis variance least significant difference tests (p 0.05). remnant index (ARI) determined using stereomicroscope (S4E; Leica Microsystems). ARI scores submitted Pearson’s chi-square test. Results highest strengths acquired < did not impact strength. lowest found increased There no differences among > Conclusion may be an alternative bonding might improve depending material.
