A flower-like morphology HA (Figure 1) can be obtained via a direct solid-state sintering method after preheat treatment of calcined eggshell and dicalcium phosphate dihydrate
at 800[degrees]C .
Only 17 out of the total 55 toothpastes have shown the list of ingredients with their amounts and most of them claim the use of calcium-containing abrasives either in the calcium carbonate or in DCPD (dicalcium phosphate dihydrate
[beta]-TCP, [beta]-Tricalcium phosphate; OCP, octacalcium phosphate; DCP, dicalcium phosphate; DCPD, dicalcium phosphate dihydrate

coatings on stainless steel substrates," Bulletin of Materials Science, vol.
When the supersaturated calcium and hydrogen phosphate ion containing nano sized calcium oxide particles paste is brushed on the surface, the ions diffuse into the dentinal tubules and form dicalcium phosphate dihydrate
precipitation at a depth of 100mm.
In this study, standard dicalcium phosphate dihydrate
(DCPD), [CaHPO.sub.4] * [2H.sub.2]O, dissolved three times faster than HA (p < 0.05).
dicalcium phosphate dihydrate
(DCPD), octacalcium phosphate, and tricalcium phosphate) and possibly a small fraction of stable phase (hydroxyapatite) were dissolved in CB reagent (Delgado et al.

Their technique involves treating teeth with aqueous solutions or gels that will cause some of the apatite -- a structural mineral in tooth enamel -- to convert into dicalcium phosphate dihydrate
, or DCPD.
