Abstract:
The invention provides a highly aligned and closely packed hollow fiber assembly, wherein the assemblies of fibrous membrane has a width-to-fiber diameter ratio (W/d) larger than 10 and the orientation of the fibers is no larger than +/−10°. Also provided is an electrospinning process for the preparation of the fiber assembly of the invention and its applications.
Abstract:
This invention is related to a kind of teeth bleaching formulation containing the vegetative enzymes extracted from plant tubers with extensively applications in cosmetic dentistry. The enzymes are susceptible to promote the decomposition (dissociation) of peroxide compounds, thus the intermediate hydroxyl free radicals are generated to turn the unpleasant stained tooth into light or colorless appearance effectively. The composition of a whitening gel may comprising 2˜50 wt % of hydrogen peroxide, 0.003˜3 wt % vegetative enzyme extract, and transferring to alkalinity approximately pH 8˜13 to achieve the high efficiency dental bleaching usage.

Abstract:
The invention provides a composite of α-calcium sulfate (CS) hemihydrate/amorphous calcium phosphate (α-CSH/ACP), comprising α-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 α-CSH/ACP composite of the invention. The one-pot process of the invention can produce α-CSH and ACP in a single process and easily obtain α-CSH/ACP composite.
Abstract:
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 γ-polyglutamic acid (γ-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.
Abstract:
The present invention relates to a process of using a heat responsive mixture to produce inorganic interconnected 3D open-cell bone substitutes which can be applied in the orthopedic or dental field for treatment of bone damage. The invention provides a simple and easily-controlled process of preparing porous inorganic bone substitute materials.

Abstract:
A gingival retraction material is prepared using fibrillated fibers to improve viscosity and combining taste-modifying agent, color agent, and kaolin filler to form a paste-like structure having the viscosity ranging from 31.0×106 cP to 71.0×106 cP. The gingival material is injectable into the patient's gingival sulcus to provide a physical active force that widens the patient's gingival sulcus by means of the material viscosity and also to control gingival tissue fluid and hemostasis so as to keep the gingival sulcus dry for further mold impressions.

Abstract:
The invention relates to a method of preparing a composite or porous composite used as a biodegradable scaffold, the composite prepared therefrom and the use of the composite. In particular, the composite is a calcium sulfate-polylactic acid composite or porous composite and the composite can be especially used as an in situ pore forming scaffold.
