AI Technical Summary
The prior art is difficult to effectively repair dentin caries, especially after the formation of caries, traditional materials need to be dried before use, resulting in collagen denaturation and lack of liquid crystal tissue.
Compositions containing uncrosslinked and undenatured collagen particles, bionic hydroxyapatite or amorphous calcium phosphate, and physiologically compatible aqueous solvents are used for the repair and regeneration of dentin. The composition can form a bionic structure by self-assembly after injection or implantation as a scaffold for dentin repair.
It realizes effective repair of demineralized dentin after the formation of caries, and through the formation of a bionic structure and good combination with dentin, the mechanical integrity of the teeth and the effect of caries prevention are enhanced.
