Crystal Structure Studies of Human Dental Apatite as a Function of Age
Figure 9
Ratios of the IR intensities of the (880 cm-1) and (870 cm-1) CO3 modes to the PO4 (960 cm-1) mode. Squares mark the B-type and open circles the A-type carbonate substitutions. An estimate of the relative carbonate content in human dental apatite as a function of the tooth-age is provided by these ratios. The lines are guides to the eyes.
