Two ophthalmic and four dental irreversible hydrocolloid materials were tested in vitro to determine the initial pH and changes in pH to completion of set over 4 minutes. The ophthalmic Moldite material became more basic during its setting whereas the ophthalmic Moldeye material remained stable throughout the setting. The other materials tested decreased in pH with time.
对两种眼科用和四种牙科用不可逆水胶体材料进行了体外测试，以确定其初始pH值以及在4分钟内凝固过程中pH值的变化。眼科用Moldite材料在凝固过程中碱性增强，而眼科用Moldeye材料在整个凝固过程中保持稳定。测试的其他材料的pH值随时间降低。
