纳米氟化钙对正畸粘接剂粘接性能影响的实验研究

王 一婷, 莫 水学

摘要

目的:探讨纳米氟化钙(Calcium fluoride nanoparticles,Nano-CaF2)对正畸托槽粘接剂的粘接强度及粘接残留指数的影响。方法:在牙釉质粘接剂中加入 0 wt%、5 wt%、10 wt%、15 wt%、20 wt% 的Nano-CaF2(分别分为NC组、A组、B组、C组、D组)。收集 50 颗健康离体前磨牙并随机分为 5 组,将托槽粘接于离体前磨牙上,测量其剪切粘接强度与粘接残留指数。结果:NC组、A组、B组、C组、D组剪切粘接强度分别为(17.22±1.61)MPa、(14.29±1.31)MPa、(10.92±1.40)MPa、(7.33±1.93)MPa、(6.78±0.99)MPa。C组和D组的组间差异无统计学意义(P>0.05),其余组间皆有统计学意义(P<0.05)。各组粘接剂残留指数比较差异没有统计学意义(P >0.05)。结论:正畸粘接剂的抗剪切粘接强度随着掺入的 Nano-CaF2 比例的增加而降低。
