Problems solved by technology

[0005] Although imported root canal filling materials are better than domestic ZOE paste, most of them are expensive
In addition, the main bactericidal ingredients in existing root canal filling materials are bactericidal and antibacterial drugs, and these drugs have certain side effects on the human body.

Embodiment 1

[0036] Mix zinc oxide and barium sulfate uniformly according to a certain ratio to make a powder, blend it with clove oil at a ratio of 2:1, and measure the flow diameter data as shown in Table 1 below.

[0037] serial number

[0038] Mix zinc oxide and nano-zirconia in a certain proportion to make a powder, and blend it with clove oil at a ratio of 2:1. The measured flow diameter data are shown in Table 2 below.

[0039] serial number

[0040] The fluidity of the root canal filling materials added with nano-zirconia is obviously better than that of barium sulfate. X-ray opacity tests were performed on the two groups of materials in Table 1 and Table 2 respectively. The X-ray attenuation of the 2mm thick disc made of root canal filling material is stronger than that of the 6mm thick aluminum plate; and the 2mm thick disc made of root canal filling material added with barium sulfate has stronger attenuation of X-ray than the 2mm thick root canal filling mater...

Embodiment 2

[0042] 51% of zinc oxide, 25% of barium sulfate, 5% of thymol, 18.75% of erythromycin and 0.25% of steroid glucocorticoid are stirred to mix evenly.

[0043] Mix the prepared powder and clove oil at a ratio of 2.5:1, and the prepared root canal filling material has low solubility, general fluidity and weak X-ray opacity.

Embodiment 3

[0045] 50% nano-zinc oxide, 23% nano-zirconia, 5% nano-hydroxyapatite, 4% thymol, 17.75% erythromycin and 0.25% steroid glucocorticoid were stirred Mix it well.

[0046] The prepared powder and clove oil are mixed at a ratio of 2.5:1, and the prepared root canal filling material has low solubility, good fluidity and X-ray resistance.

Abstract

The present invention relates to oral root canal treating material, and is especially a kind of root canal filling material of nanometer zinc oxide and clove oil and its preparation process. The root canal filling material consists of powder in 60-75 wt% and clove oil in 25-40 wt%, and the powder consists of inorganic nanometer ZnO of 10-280 nm size 46-90 wt%, inorganic nanometer ZrO2 of 10- 600 nm size 5-40 wt%, inorganic nanometer hydro xyapatite of 80-100 nm size not more than 10 wt%, inorganic nanometer silver carrying antibiotic powder of 90-150 nm size not more than 10 wt%, thymol 2-10 wt%, anaerobe resisting medicine not more than 10 wt%, antibiotic not more than 25 wt%, and steroid glucocorticoid <1 wt%. Compared with available technology, the present invention has the advantages of high X-ray resistance, high flowability, high biocompatibility, low dissolubility and low cost.

Description

technical field [0001] The invention belongs to the field of medical oral root canal treatment materials, in particular to a nanometer zinc oxide clove oil root canal filling material and a preparation method thereof. Background technique [0002] In the root of each tooth, there is a passage through which nerves and blood vessels pass, called the root canal. Root canal treatment is performed in this channel, and usually includes three steps: root canal preparation, root canal disinfection and root canal filling: first, thoroughly remove the inflamed and necrotic dental nerve, as well as a large number of bacteria and decayed substances with instruments , Put the root canal filling material after poisoning, and the root canal is tightly filled to prevent the spread of infection. This method can save the affected tooth from extraction as much as possible, reduce the infection of the lesion, and restore the health of the affected tooth. It is an effective method for the treat...
