我们研究了每周应用含有表面反应型预反应玻璃离子（S-PRG）填料的糊剂对牙本质矿化的影响。使用含有S-PRG填充剂（0、5和30%）的糊剂对人牙本质块进行脱矿和抛光，然后将其浸入再矿化溶液中1个月。浸泡期间进行纳米压痕测试，并使用扫描电子显微镜检查牙本质表面。使用含纳米羟基磷灰石的糊剂进行比较。浸泡在脱矿质溶液中对所有试样的力学性能都有显着的负面影响。与其他试样相比，含S-PRG填料的抛光膏抛光的试样在矿化溶液中浸泡1个月后的力学性能显著恢复。牙本质小管再矿化后，用含S-PRG填料和含纳米羟基磷灰石的糊剂抛光的标本中的牙本质小管再矿化层填充开放的牙本质小管。含S-PRG填充剂的糊剂可帮助牙本质矿化。
We investigated the effects of the weekly application of pastes containing a surface reaction-type pre-reacted glass-ionomer (S-PRG) filler on dentin remineralization. Human dentin blocks were demineralized and polished using pastes containing S-PRG filler (0, 5, and 30%), and then immersed in remineralizing solution for 1 month. Nanoindentation testing was carried out during the immersion period, and the dentin surfaces were examined using scanning electron microscopy. A nano-hydroxyapatite-containing paste was used for comparison. Immersion in demineralization solution had a marked negative effect on the mechanical properties in all specimens. The mechanical properties of specimens polished with S-PRG filler-containing pastes recovered significantly after immersion in remineralization solution for 1 month compared with the other specimens. After remineralization, the open dentinal tubules were filled with a remineralization layer in specimens polished with S-PRG filler-containing and nano-hydroxyapatite-containing pastes. S-PRG filler-containing pastes can aid dentin remineralization.
