摘要
目的 通过离体牙试验 ,阐明口腔正畸含氟牙釉质粘接剂的粘接强度。方法 测试和比较含氟牙釉质粘接剂及不含氟牙釉质粘接剂的剪切强度以及扫描电镜下粘接剂渗入酸蚀后牙釉质表面形成的树脂钉突长度。结果 使用含氟牙釉质粘接剂与使用不含氟牙釉质粘接剂的托槽 牙界面剪切强度及粘接剂渗入酸蚀后牙釉质表面形成的树脂钉突长度均无显著性差异。
Objective The bond effect of the fluoride-releasing orthodontic adhesive was studied in vitro. Methods To test and compare the shear bond strength and the penetration depth of resin tags of fluoride-releasing orthodontic adhesives with those of the traditional orthodontic adhesive.Results There are no significant statistically differences between fluoride-releasing orthodontic adhesive and the control (nonfluoride) in shear bond strength and penetration depth of resin tags. Conclusion There are no significant statistically differences between fluoride-releasing orthodontic adhesive and the control (nonfluoride) in bond effect.
