Burns Incl Therm Inj. 1982 Sep;9(1):46-8. doi: 10.1016/0305-4179(82)90135-8.
Four female pupils at a technical school received hand burns while trying to make moulds of their hands using a dental plaster instead of ordinary plaster-of-Paris. In three cases the burns were so severe that several fingers had to be amputated due to irreversible tissue damage. The severity of the burns is explained on the basis of an experimental study where it was demonstrated that the temperature of hardening dental plaster rose to 70 degrees C and had a hardness that was 10-times greater than ordinary plaster-of-Paris. This should serve as a warning against the use of dental plaster in direct casting of living tissue. However, the technique used here is also considered dangerous, as ordinary plaster-of-Paris under certain circumstances could also cause severe burns.
一所技术学校的四名女学生在尝试用牙科石膏而非普通熟石膏制作手部模型时手部被烧伤。在三起案例中，烧伤非常严重，由于组织损伤无法逆转，几根手指不得不被截肢。根据一项实验研究对烧伤的严重程度进行了解释，该研究表明，硬化的牙科石膏温度升至70摄氏度，硬度是普通熟石膏的10倍。这应该作为一个警告，提醒人们不要将牙科石膏直接用于活体组织的铸造。然而，这里使用的技术也被认为是危险的，因为普通熟石膏在某些情况下也可能导致严重烧伤。
