To evaluate four protocols for removal of fluorescent materials after bracket debonding.
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).
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.
Auxiliary devices were useful for removal of fluorescent residue after bracket debonding.
评估四种去除托槽脱粘后荧光材料的方案。
根据分组（n = 10）对40个牛牙釉质表面进行树脂去除：传统方法（C）、白色发光二极管（W）、能显示荧光的发光二极管（F）和荧光透镜（FL）。进行了以下分析：样本厚度、树脂残留的表面积以及树脂残留或牙釉质磨损的深度区域。采用方差分析和Tukey检验分析样本厚度（P≤0.05）。面积测量通过Kruskal-Wallis检验和Dunn检验进行分析（P≤0.05）。
FL组牙釉质厚度减少最多。F组的最终厚度与其他组相似。C组和W组的树脂残留表面积最大，而FL组的树脂残留去除量最大。C组树脂残留深度区域最大。FL组和F组牙釉质损失最多，树脂残留量最少；相比之下，C组和W组牙釉质磨损区域最少，树脂残留区域最多。
辅助装置有助于去除托槽脱粘后的荧光残留物。
