Attempts to promote crystal growth in maturation stage enamel from rat incisors were carried out by incubation in saturated solutions of calcium phosphate. Resulting crystallites were visualised in the TEM and the dimensions of their profiles measured. No crystal growth was observed unless the maturation stage enamel was first pretreated with either 8M urea or sodium hypochlorite to remove residual protein matrix. The results suggest that the protein matrix plays an important role in the control of crystal growth in vivo.
通过在磷酸钙饱和溶液中孵育，尝试促进大鼠切牙成熟阶段牙釉质中的晶体生长。在透射电子显微镜（TEM）下观察生成的微晶，并测量其轮廓尺寸。除非先用8M尿素或次氯酸钠对成熟阶段的牙釉质进行预处理以去除残留的蛋白质基质，否则未观察到晶体生长。结果表明，蛋白质基质在体内晶体生长的控制中起重要作用。
