Influence of saliva contamination on the shear bond strength of orthodontic brackets bonded with self-etching adhesive systems

Introduction Our objective was to evaluate the influence of saliva contamination on the shear bond strength of orthodontic brackets bonded with self-etching primers.

description Introduction Our objective was to evaluate the influence of saliva contamination on the shear bond strength of orthodontic brackets bonded with self-etching primers. Methods One hundred thirty-five bovine incisors were randomly divided into 3 groups, and exposed enamel surfaces were bonded with Transbond Plus Self Etching Primer (TB) (3M Unitek, Monrovia, Calif), Adhese Single Bottle (AD) (Ivoclar, Vivadent, Schaan, Liechtenstein), and Self Etch Bond (SE) (Vigodent, Rio de Janeiro, Brazil). Each group was subdivided into 3 treatments (n = 15): saliva contamination (S), saliva contamination and deionized water rinsing (SW), and no salivary contamination (C). Resin composite (Z-100, 3M/ESPE, Salt Lake City, Utah) was applied to all samples to bond the orthodontic brackets. Shear bond strength testing was carried out in a universal testing machine operating at 1.0 mm per minute. Results The results were statistically analyzed with 2-way analysis of variance (ANOVA) and Tukey tests ( P
