Abstract:

Biodentine is a bioactive dentin replacement material whose main component is high-purity tricalcium silicate without dicalcium silicate. It has a shorter cure time; although it has a higher solubility, it hardly affects the volume of the material. It has a low X-ray barrier property, low porosity, high bulk density, and high compressive strength and is not affected by moisture or a dry environment. It has strong acid corrosion resistance, can increase dentin resistance, and has biocompatibility due to the lack of cytotoxicity. It has antibacterial activity against various bacteria, with strong antibacterial activity against Streptococcus sanguis. Since 2010, Biodentine has been widely used in clinical treatments such as dental restoration, pulp capping, pulpectomy, et al. In clinical applications, Biodentine is primarily used as a permanent dentin substitute or as a temporary enamel substitute within 6 months. As a new dentin substitute material with a short clinical application time, the long-term efficacy of Biodentine requires further follow-up observation studies.

摘要:

Biodentine是一种生物活性牙本质替代材料,其主要成分为高纯度的硅酸三钙,而不含有硅酸二钙。Biodentine的固化时间较短,虽然其溶解度较高但几乎不影响材料体积。X-ray阻射性小,孔隙率较低,容积密度较高,抗压强度大且不受潮湿或干燥环境影响,抗酸蚀能力强,可增加牙本质抗折能力,无细胞毒性,具有良好的生物相容性,对多种细菌具有抗菌活性,尤其是对血链球菌具有较强的抗菌性。2010年开始,Biodentine广泛应用于牙体修复、盖髓术、牙髓切断术、等临床治疗。在临床应用中,Biodentine主要作为永久性的牙本质替代物或是在6个月内作为临时的牙釉质替代物。Biodentine作为一种新型的牙本质替代材料在临床中应用的还时间较短,其远期疗效仍有待进一步的随访观察。
