title: Efficacy of auxiliary devices for removal of fluorescent residue after bracket debonding.
abstract: OBJECTIVE
  To evaluate four protocols for removal of fluorescent materials after bracket debonding.
  
  
  METHODS
  Resin removal from 40 bovine enamel surfaces was performed according to groups (n = 10): conventional (C), white LED (W), LED that evidenced fluorescence (F), and fluorescent lens (FL). The following analyses were performed: sample thickness, superficial area of resin residue, and areas of resin residue or worn enamel in depth. ANOVA and Tukey tests were used to analyze sample thickness (P ≤ .05). Area measurements were analyzed by Kruskal-Wallis and Dunn's tests (P ≤ .05).
  
  
  RESULTS
  The FL group showed the highest reduction in enamel thickness. F group final thickness was similar to that of other groups. The largest superficial areas of resin residue were found for the C and W groups, while the FL group had the greatest removal of resin residue. The C group exhibited the largest area in depth of resin residue. The FL and F groups exhibited the most loss of enamel with the least amount of resin residue; in contrast, the C and W groups presented the fewest areas of worn enamel and the most areas of resin residue.
  
  
  CONCLUSIONS
  Auxiliary devices were useful for removal of fluorescent residue after bracket debonding.
