为了研究含碳酸盐磷灰石对龋齿的敏感性，在40、60和80 ℃下制备具有各种堆积度和碳酸盐含量的合成CO 3磷灰石。C. CO 3磷灰石的结晶度随碳酸盐含量的增加而降低，随温度的升高而升高。CO 3磷灰石在pH 4-8的37 ℃下的表观溶解度。C与结晶度近似相关。特别地，在80 ℃下合成的CO 3磷灰石的溶解度的增加程度。C，因此具有高结晶度的变化很大，在0-3重量%的碳酸盐含量的区域，这接近釉磷灰石。在这项研究中得到的溶解度和结晶度之间的关系可能是一个有用的指标的敏感性含碳酸盐磷灰石酸。
To study the susceptibility of carbonate-containing apatites to caries, synthetic CO3 apatites with various crystallinities and carbonate contents were prepared at 40, 60 and 80.degree. C. The crystallinity of CO3 apatites decreased with carbonate content and increased with temperature. The apparent solubility of CO3 apatites over pH 4-8 at 37.degree. C was related approximately to their crystallinity. In particular, the degree of increase in the solubility of CO3 apatites synthesized at 80.degree. C and thus having high crystallinity changed greatly in the region of 0-3 wt% of carbonate content, which approximates to that of enamel apatites. The relationship between solubility and crystallinity obtained in this study may be a useful indicator of the susceptibility of carbonate-containing apatites to acid.
