Embodiment 2
[0036] Weigh a certain amount of root canal sealer EndoREZ, add DMADDM with a mass fraction of 2.5%, add ferric iron tetroxide magnetic nanoparticle MNP at a mass fraction of 2%, and carry out mixing treatment at room temperature for 5 minutes to obtain the dental material of the present invention .
Embodiment 3
[0037] Embodiment 3 screening and performance test
[0038] (1) Preparation of experimental materials
[0039] Weigh a certain amount of root canal sealant, add DMADDM with a mass fraction of 2.5%, divide it into 3 groups in equal proportions, add MNP according to the mass fraction of 0%, 1%, and 2%, and carry out mixing treatment at room temperature for 5 minutes. .
[0040] For the EndoREZ group, mix and mix for 5 minutes at room temperature, and set aside.
[0041] (2) Performance testing
[0042] Grouped according to the mass fraction, the cytotoxicity, solubility, sealant penetration to dentin, and antibacterial properties of the above materials were tested respectively, with 6 samples in each group
