Embodiment 1
[0020] 1) Take the caries-free premolars extracted for orthodontic treatment, remove the roots and enamel, and cut them into 2*2*1.5mm by using a high-speed turbine 3 Dentin block, the dentin block is dissolved in 2ml of phosphoric acid solution with a weight percentage of 85%, slowly shaken and soaked in a shaking table at a temperature of 4°C for three days to obtain a reaction solution, and then the resulting reaction solution is heated at 4°C and 1200rpm Centrifuge and separate, take the supernatant to obtain the dentin demineralization solution, and store it at 4°C for later use;
[0021] 2) Add 0.5 ml of 30% hydrogen peroxide to the dentin demineralization solution, stir and mix evenly, and perform foaming treatment;
[0022] 3) Add calcium hydroxide powder with a particle size of 2-10 μm to the dentin demineralization solution after foaming treatment, stir while adding, and detect the pH value of the reactant by potentiometric method, stop adding hydrogen until the pH i...
Embodiment 2
[0027] 1) Take the caries-free premolars extracted for orthodontic treatment, remove the roots and enamel, and cut them into 2*2*1.5mm by using a high-speed turbine 3 Dentin block, the dentin block is dissolved in 2ml of phosphoric acid solution with a weight percentage of 90%, slowly shaken and soaked in a shaking table at a temperature of 4°C for three days to obtain a reaction solution, and then the resulting reaction solution is heated at 4°C, 1200rpm Centrifuge and separate, take the supernatant to obtain the dentin demineralization solution, and store it at 4°C for later use;
[0028] 2) Add 0.4ml of 40% hydrogen peroxide by weight to the dentin demineralization solution, stir and mix evenly, and perform foaming treatment;
[0029] 3) Add calcium hydroxide powder with a particle size of 2-10 μm to the dentin demineralization solution after foaming treatment, stir while adding, and detect the pH value of the reactant by potentiometric method, stop adding hydrogen until th...
Embodiment 3
[0033] 1) Take the caries-free premolars extracted for orthodontic treatment, remove the roots and enamel, and cut them into 2*2*1.5mm by using a high-speed turbine 3 2 pieces of dentin blocks, the dentin blocks were dissolved in 4ml of phosphoric acid solution with a weight percentage of 70%, slowly shaken and soaked in a shaking table at a temperature of 4°C for three days to obtain a reaction solution, and then the resulting reaction solution was placed at 4°C, Centrifuge at 1200rpm, take the supernatant to obtain the dentin demineralization solution, and store it at 4°C for later use;
[0034] 2) Add 1ml of 20% hydrogen peroxide by weight to the dentin demineralization solution, stir and mix evenly, and perform foaming treatment;
[0035]3) Add calcium hydroxide powder with a particle size of 2-10 μm to the dentin demineralization solution after foaming treatment, stir while adding, and detect the pH value of the reactant by potentiometric method, stop adding hydrogen unti...
