Abstract Calcium sulfate (CS) is a reasonable alternative to autogenous dental bone graft and is used as a bone filler or for the treatment of bone defects. Medical grade CS must be sterilized, usually by gamma-irradiation. In this study the structures of CS polymorphs, calcium sulfate dihydrate and calcium sulfate hemihydrate, have been investigated with electron paramagnetic resonance (EPR) spectroscopy, X-ray diffraction, thermogravimetric analyses and infrared spectroscopy. The influences of saline and artificial saliva on gamma-induced radical concentrations have been monitored.

生理盐水和人工唾液对基于硫酸钙的牙科骨移植材料中γ诱导自由基浓度的影响的EPR光谱研究

摘要 硫酸钙 (CS) 是自体牙科骨移植物的合理替代品,可用作骨填充物或治疗骨缺损。医疗级 CS 必须经过灭菌,通常是通过伽马射线照射。在这项研究中,用电子顺磁共振 (EPR) 光谱、X 射线衍射、热重分析和红外光谱研究了 CS 多晶型物、二水合硫酸钙和半水合硫酸钙的结构。已经监测了盐水和人工唾液对 γ 诱导的自由基浓度的影响。
