Fluoride content and Ca/P ratio

Sample F content (mass %) (mean ± sd;n = 2) Ca/P molar ratio (mean ± sd;n=2)
CPC0 0 1.37 ± 0.05(a)
FA-CPC1 0.4 ± 0.1 1.42 ± 0.04
FA-CPC2 1.8 ± 0.2 1.53 ± 0.06
FA-CPC3 3.1 ± 0.2 1.69 ± 0.07(b)
(a)

Values connected by a line are not significantly (p > 0.05) different.

(b)

Significantly different (p < 0.05) from other Ca/P values.
