Abstract

Zusammenfassung

Aim.  The purpose of this work is to evaluate the effectiveness of one self-etching and two filled orthodontic primers on enamel demineralization around orthodontic brackets. Methods.  Brackets were bonded to 84 bovine teeth and the vestibular enamel surfaces covered with acid-resistant nail varnish exposing 1 mm of space on each side of the bracket base. The teeth were allocated to four groups, using either Transbond™ XT conventional primer on etched enamel (group 1), Transbond™ Plus Self-Etching Primer on untreated enamel (group 2), Pro Seal® filled resin primer on etched enamel (group 3), or Opal Seal® filled resin primer on etched enamel (group 4). Each tooth was subjected to 15,000 strokes of brushing followed by exposure to an acid challenge. Calcium-ion release from each sample was calculated using atomic absorption spectrophotometry. Data were analyzed using one-way ANOVA and a post hoc Tukey test. Differences were considered statistically significant at p≤0.05. Results.  Statistically significant differences were observed between the four groups (p
