“…Preferential dissolution of carbonate has been reported [Coolidge and Jacobs, 1957;Little, Cueto and Rowley, 1962a;Johansen, 1965;Hallsworth, Weatherell and Robinson, 1973) of magnesium (Johansen, 1965;Suga, 1970;Hallsworth, Robinson and Weatherell, 1972) and of sodium (Little, Posen and Singer, 1962b). Using microradiography in combination with electron-microprobe analysis, Driessens et al (1986) confirmed the preferential loss of sodium, but they also found a preferential retention of chloride in natural carious lesions.…”

“…The multiple-band fitting model data in table 2 reports mean carbonate values that vary by almost 100% for the same measurement data, suggesting that there may be problems with adapting these synthetic apatite models to biological apatites. Compounding this problem is the historical uncertainty about the actual carbonate concentrations in dental apatites due to individual (biological) diversity [Sakae, 2006], carbonate gradients within individual teeth [Coolidge and Jacobs, 1957;Mayer et al, 1988] and the variety of different car- Table 1.

Carbonate determination in dental apatites such as dentine and enamel is important for studying the dynamics of dental caries and developmental defects of these tissues. Traditionally, these determinations have been performed by acidic digestion with the subsequent measurement of released carbon dioxide gas. As an alternative, Raman spectroscopy has been used for the determination of carbonate in synthetic carbonated apatites with at least four analytical methods published thus far. However, these methods have not been applied to biological apatites. The aim of this comparative study was to test the suitability of these four methods for the determination of B-type carbonate in human enamel and dentine. A method for determining the A-type carbonate content of enamel using the Raman technique is also presented. Raman spectra were obtained from 10 human enamel and dentine samples and analysed with each of the four methods using either a single or multiple ν₁(PO₄^3–) band spectral fitting model. Each of the methods resulted in a different determination for the carbonate content when using the same measurement data. The method that used the full-width-at-half-maximum of the ν₁(PO₄^3–) band to determine the B-type carbonate concentration was found to be in best agreement with (i) the results (using the acid digestion method) of teeth collected from the same sample population and (ii) previously reported values for both enamel and dentine. The use of a multiple-band spectral fitting model produced the highest determination precision (particularly in the case of dentine).

“…Darling (1961) reported that the first stage of caries occurs in the interprismatic regions of enamel, and it seems to involve a preferential dissolution of carbonate-rich mineral (Coolidge and Jacobs, 1957;Hallsworth et al, 1972Hallsworth et al, , 1973. Hiller et al (1975) have suggested that it may be in the interprismatic enamel that the least dilution of the original carbonate concentration occurs.…”

Carbonate Content in Developing Human and Bovine Enamel

The present study describes the detailed changes in carbonate distribution throughout the different stages of development in human and bovine enamel, from early formation to maturation. Twenty-two human maxillary and mandibular deciduous anterior teeth and 46 bovine teeth were studied. The major mineral ions, calcium and phosphorus, were also analyzed to facilitate comparison of carbonate content with progressing mineralization. The results showed that as enamel matured and mineral concentration increased, carbonate concentration decreased. The observed decrease in percent carbonate per weight enamel mineral may be due to dilution by an influx of relatively carbonate-free mineral, and could, in part, explain the observed increase in crystallinity of enamel mineral as the tissue matures.
