The invention provides an anion-containing calcium phosphate compound, composition and dental patch comprising the same and their use in remineralizing teeth. The anion-containing calcium phosphate compound has the following formula:(Ca)(anion)(PO)wherein 2x=(a*y+3z);

Type of anion-containing calcium phosphate compound for dental remineralization

The invention provides a composite of &#x3b1;-calcium sulfate (CS) hemihydrate/amorphous calcium phosphate (&#x3b1;-CSH/ACP), comprising &#x3b1;-CSH and ACP at a weight ratio of about 10:90 to about 90:10. Particularly, the composite of the invention has a resorption period of 3-6 months. The invention also provides a one-pot process for producing &#x3b1;-CSH/ACP composite of the invention. The one-pot process of the invention can produce &#x3b1;-CSH and ACP in a single process and easily obtain &#x3b1;-CSH/ACP composite.

The invention relates to a simple and high yield process for producing a regenerated silk fibroin which does not need dialysis. Particularly, a process of the invention is characterized in that the silk fibroin is precipitated by applying a shear stress and/or changing the solvent power of the fibroin solution. The process of the invention simplifies the process of producing silk fibroin and greatly shortens the process time to 1 to 2 hours, whereas the conventional dialysis process is complex and needs around 2 to 3 days. In addition to reducing the time needed, the process of the invention can increase productivity of silk fibroin by at least 8%.

High yield dialysis-free process for producing organosoluble regenerated silk fibroin

A novel amorphous divalent metal ion salt for enhancing the manageability of a Portland cement and its application in dental field are disclosed. Typical formula (I), (II), or (III) of this amorphous metal ion salt are shown as following: 

Amorphous metal salt for facilitating the handling property of portland cements and dental applications thereof

The invention is directed to a calcium phosphate complex and the composition containing the same for oral care applications, in which the calcium phosphate complex is formed by chelating the &#x3b3;-polyglutamic acid (&#x3b3;-PGA) with amorphous calcium phosphate (ACP). This complex can prevent crystallization of ACP and maintain its high solubility. The calcium phosphate complex has superior mucoadhesion properties, allowing it to remain in the mouth longer and offering effective buffering, by which dental caries can be alleviated and prevented.
