“…An additive protection of the teeth with water-borne fluoride and dietary phosphate supplement has been reported by Mühlemann et al [1961] and van Reen et al [1962]. On the other hand, Johansen [1960], Navia and H arris [1969] and N izel et al [1970] obtained a similar effect with dietary phosphate and fluoride ad ditives. In a later study of the Swiss group [Mühlemann and König, 1964] a combination of Na.HPO., and NaF was found no more effective than NaF alone.…”

A total of 49 rats was littermate-distributed into three dietary groups when 21 days old. The control group (C) was fed a cariogenic nutritionally adequate high- sucrose diet for 40 days. The second group (BP) received the same diet as group C except that 4% of the sucrose component of the diet was replaced by a combination Phosphate, dietary NaHCO₃ + KH₂PO₄ (mole ratio 9.82/1). The third group (BPF) was fed the same diet as group BP except that NaF was also added to the sucrose to give 10 ppm F addition to the whole of diet. The mean gain of body weight in the BPF group was 55% higher than in group C (p < 0.001). In the BPF group, also the weight and length of the femurs were greater than in group C. The mean number of fissure cavities in lower molars was 76% less in group BP (p < 0.01) and 80% less in group BPF (p < 0.01) than in group C. The mean number of approximal lesions involving the dentino-enamel junction was in group BPF 65% less than in group C (p < 0.01) and 32% less in group BP than in group C (p < 0.1). A nearly tenfold increase in bone fluoride was found in the animals of the BPF group.

“…[12] The chemical composition of teeth can also be influenced by numerous factors including diet/nutrition, age, dental diseases, type of teeth (deciduous or permanent), and genetic factors. [13,14] Dental hypomineralization is a relatively common anomaly. Typically, it occurs within the enamel and presents with white, yellow, or brown opacities with altered translucency.…”

Low‐wavenumber Raman spectroscopy is demonstrated for its potential to analyse mineralization abnormalities in human teeth. Four different dental samples were analysed in this study, denoted as healthy control, mild hypomineralization, enamel caries, and AI (severely degraded due to Amelogenesis imperfecta). All specimens were imaged using principal component analysis. The spectra from low‐ wavenumber and midwavenumber regions were simultaneously collected allowing for direct comparison between the two regions. This approach provided a method to characterize structural and chemical variation within samples. Structurally different hydroxyapatite was found to be present in the surface and bulk of the enamel. The thin outer layer of the enamel contained the most structurally ordered mineral. The obtained Raman images enabled characterization and comparison of lesion domains as well as relative hydroxyapatite abundances across all dental samples.

“…The reaction is mainly the result of a local effect on the tooth surface, and involves a retardation of the development of caries rather than a prevention of the initiation of caries. Johansen (1960) observed that when 2% CaHP04 and fluoride were fed together, caries development was less than when either was fed alone. Muhlemann and coworkers (1961a) noted a similar response when 0.4% sodium acid phosphate and 100 ppm Fwere added to the diet of rats.…”
