The purpose of this study was to investigate the degree of pulp irritation of a newly developed light-activated fluoride-releasing adhesive resin liner using canine teeth compared to the amount caused by a negative control, zinc oxide eugenol cement (ZOE), and a positive control, silicate cement (silicate). In the cases of unexposed pulp, this experimental liner showed none, slight or moderate pulpal changes at 3 d postoperatively. At 30 and 90 d, no pulpal response to the experimental liner was detected in almost all cases. These findings were similar to the ZOE and better than the silicate. There was less evidence of pulpal irritation produced by the experimental liner. This material seems to be safe to the pulp under the conditions of this study.
本研究的目的是，与阴性对照物氧化锌丁香酚水门汀（ZOE）和阳性对照物硅酸盐水泥（硅酸盐）所引起的牙髓刺激程度相比，研究一种新开发的光活化释氟粘结性树脂衬层对犬牙的牙髓刺激程度。在未暴露牙髓的情况下，这种实验性衬层在术后3天时未显示、或仅显示轻微或中度的牙髓变化。在30天和90天时，几乎在所有病例中均未检测到对实验性衬层的牙髓反应。这些结果与ZOE相似，且优于硅酸盐。实验性衬层产生的牙髓刺激证据较少。在本研究条件下，这种材料似乎对牙髓是安全的。
