Dental tampon and preparation method thereof

Abstract

The invention provides a dental tampon which contains fibrous protein and polysaccharides, wherein the fibrous protein contains collagen, and the collagen accounts for 10-90% of the total mass of thedental tampon according to mass percent; and the dental tampon can also contain organic polymeric materials, and the organic polymeric materials account for 20-0.05% of the total mass of the dental tampon according to mass percent. The invention further provides a preparation method of the dental tampon, comprising the steps of stirring and mixing raw materials of the dental tampon, and then sizing and freeze-drying the raw materials in a mold to obtain the integrally formed dental tampon. The dental tampon mainly uses the collagen for stopping bleeding, has the shape conforming to tooth structure characteristics of all age groups, is a disposable sterile non-toxic dental haemostatic material, has convenient use and simple operation, and can stop bleeding for the gingival wound surface caused by tooth extraction.

Description

technical field [0001] The invention relates to the field of dental medical supplies, in particular to a dental hemostatic plug and a preparation method thereof. Background technique [0002] At present, the number of patients with clinical dental diseases is increasing, and the patients involve children, young people, middle-aged and elderly people. Among them, the incidence rate of dental caries in children is as high as 90%, and the prevalence rate of dental caries in the elderly is as high as 98.4%. The clinical thorough treatment of dental disease mostly adopts the mode of tooth extraction and filling. However, the tooth extraction process will cause bleeding due to wounds in the gums. The conventional method of hemostasis is the doctor's self-made cotton ball or gauze ball to stop the bleeding. Generally, the patient is required to bite the cotton ball or gauze ball to stop the bleeding after tooth extraction, and the patient can spit it out after 30 minutes to 1 hou...

Problems solved by technology

[0003] The method of using homemade cotton balls or gauze balls by doctors to stop bleeding has the following disadvantages: 1. It takes a long time to achieve complete hemostasis and requires the close cooperation of patients; 2. The cotton yarn needs to be made by clinicians on site to meet the specifications of patients. , relatively time-consuming, patients often need to wait for a long time; 3. Cotton gauze hemostatic material is not a disposable sanitary product, which has no safety guarantee for patients; For patients with difficulty in hemostasis of larger wounds, hemostatic powder and hemostatic agents must be used locally, or the wound should be sutured to stop bleeding; 5. Cotton gauze hemostasis is only a physical hemostasis method, and cannot repair and heal the wound
