Abstract
This invention involves the use of amorphous calcium compounds such as: amorphous calcium phosphate (ACP), amorphous calcium phosphate fluoride (ACPF) and amorphous calcium carbonate phosphate (ACCP) for use in remineralizing teeth. These amorphous compounds or solutions which form the amorphous compounds, when applied either onto or into dental tissue prevent and/or repair dental weaknesses such as dental caries, exposed roots and dentin sensitivity. The compounds have the highest solubilities, fastest formation rates and fastest conversion rates (to apatite) among all the calcium phosphorate under physiological conditions. Moreover, in the presence to fluoride the amorphous compound convert rapidly to fluoride containing apatite.
Claims6
A dental restorative comprising in combination:
- a substantially non-aqueous, non-toxic carrier capable of suspension of amorphous calcium compounds or a material that will form amorphous calcium compounds therein;
- and
- a material comprising or that will form amorphous calcium phosphate, amorphous calcium phosphate fluoride or amorphous calcium carbonate phosphate suspended within said carrier;
- whereby when the combination is contacted with the teeth, a calcium phosphate compound is deposited and apatite is formed on and in the teeth.
A dental restorative comprising a substantially aqueous slurry containing amorphous calcium phosphate fluoride;
- whereby when applied to a tooth the slurry precipitates a calcium phosphate fluoride compound on and into the tooth, said calcium phosphate fluoride then forming fluoride containing apatite.
A dental restorative comprising a substantially aqueous slurry containing amorphous calcium carbonate phosphate;
- whereby when applied to a tooth the slurry precipitates a calcium carbonate phosphate compound on and into the tooth, said calcium carbonate phosphate then forming apatite.
