Problems solved by technology

In the case of this fluorine coating agent, the caries prevention effect can be expected for a long time by keeping the coating film for more than one month to continuously release fluorine ions, but once it is exposed to light, it is cured immediately to form a coating quickly. The membrane prevents the agent from penetrating into the inside of the dentinal tubules of the tooth, resulting in a decrease in the blocking force of the dentinal tubules, so the effect of suppressing sensory hypersensitivity cannot be expected

preparation example Construction

[0067]On the other hand, another embodiment of the present invention relates to a preparation method of a fluorine coating agent having improved dentin tubule penetration and coating retention, the preparation method may include: a first dissolving step, by A high molecular weight polyvinyl acetate (Poly(vinyl acetate), PVAc) with an average molecular weight of 300,000 to 600,000 is dissolved in a solvent to prepare a first solution; in a second dissolving step, rosin is dissolved in a solvent to prepare a second solution; and In the mixing step, the second solution, the fluorine compound and the emulsifier are added to the first solution and stirred.

[0068] Since the specific descriptions of the solvent, rosin, fluorine compound, and emulsifier used in the above-mentioned preparation method of the fluorine coating agent have been mentioned above, they will be omitted here.

[0069] The above-mentioned first dissolving step is a step of preparing a first solution by dissolvi...

[0079] Preparation of fluorine coating agent

[0080] First, polyvinyl acetate having the weight average molecular weight shown in Table 1 below was evaporated in 94% ethanol at 65° C. to prepare a 30% PVAc solution, ie, a first solution.

[0081] Then, rosin was steamed at 65° C. in 94% ethanol to prepare a 70% rosin solution, ie, a second solution.

[0082] In the first solution above, mix the second solution, fluorine compound, CPP-ACP, silicon dioxide, potassium nitrate and emulsifier in the same ratio as in Table 1 below to prepare as figure 1 Example 1 and Comparative Example 2 of the fluorine coating agent shown.

[0088] Phase Separation Phenomena According to Emulsifier Conditions

[0089] 1) Observe the phase separation phenomenon according to whether emulsifier is included

[0090] First, in order to confirm the phase separation phenomenon depending on whether or not to add an emulsifier, a control group (B) was prepared in the same preparation method as Example 1 (A) of the above-mentioned preparation example except that a solvent was further added instead of the emulsifier.

[0091] Put 10 ml of each of the above-mentioned Example 1 and the control group (B) into conical tubes, let stand at room temperature for 45 days, and then observe whether phase separation occurs.

[0092] Such as figure 2 As shown, after 45 days, phase separation is hardly observed in Example 1 (A) containing emulsifier, but in the control group (B) without emulsifier, it can be confirmed that polyvinyl acetate and hydrogenated rosin , the precipitated layer (b) and the supernatant (a) formed by the prec...

Abstract

The present invention relates to a fluorine coating agent having enhanced dental tubule permeability and coating endurance, and a method for preparing the same. The fluorine coating agent applied on the surface of a tooth is enhanced in abrasion resistance to increase a period of time during which a coating membrane lasts, thereby preventing dental caries. Further, the curing time of the fluorinecoating agent can be controlled to allow the agent to permeate and thus block the dental tubule.

Description

technical field [0001] The present invention relates to a fluorine coating agent with improved dentin tubule penetration and coating retention and a preparation method thereof, which improves dentin tubules by adjusting the curing time of the fluorine coating agent coated on the tooth surface. Penetration, thereby suppressing dentin hypersensitivity, and improving coating retention by including high-molecular-weight polyvinyl acetate in the fluorine coating agent to impart caries-resistant properties to tooth tissue for a long period of time. Background technique [0002] In dental plaque where bacteria accumulate in the oral cavity, bacteria decompose nutrients (especially monosaccharides) ingested by the host to produce acid components, and the resulting acid components dissolve calcium salts in inorganic components constituting teeth, resulting in chemical Structural defects, tooth damage, and thus dental caries. [0003] Among the various acid components produced by pla...
