OBJECTIVE
To evaluate four protocols for removal of fluorescent materials after bracket debonding.
MATERIALS AND 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.
CONCLUSION
Auxiliary devices were useful for removal of fluorescent residue after bracket debonding.
目的
评估四种去除托槽脱粘后荧光材料的方案。
材料与方法
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）。
结果
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。
结论
辅助装置有助于去除托槽脱粘后的荧光残留物。
