目前,多种材料被用来封闭牙本质小管,以降低龋病发生或牙齿敏感度。这其中,氟化物被证实有明显抗龋效果。近年来,四氟化钛(TiF_4)被证实能有效地保护牙体硬组织,井能与玷污层和牙本质小管发生作用。但其细胞毒性作用如何,尚不清楚。本文对此进行探讨。 作者制备3种溶液:1.36％氟化钠(0.323 MF,pH=8.45),1.36％酸性氟化磷酸(APF,0.323 MF,pH=1.35),1.00％TiF_4(0.323 MF,pH=1.35)。将50颗
Currently, a variety of materials are used to seal dentinal tubules to reduce dental caries or tooth sensitivity. Among them, fluoride has been shown to have a significant anti-carious effect. In recent years, titanium tetrafluoride (TiF 4) has been shown to effectively protect dental hard tissue and to interact with smeared layers and dentinal tubules. However, its cytotoxic effect is not clear. This article discusses this. The authors prepared three solutions: 1.36% sodium fluoride (0.323 MF, pH = 8.45), 1.36% acidic fluorinated phosphoric acid (APF, 0.323 MF, pH = 1.35), 1.00% TiF_4 (0.323 MF, pH = 1.35). Will be 50
