preparation example Construction

[0040] The preparation method of each embodiment oral smear comprises the steps:

[0041] step 1

[0042] Dissolve sodium phytate, potassium nitrate, strontium chloride, sodium pyrophosphate and sodium saccharin with deionized water, stir and dissolve to form an aqueous phase solution;

[0043] step 2

[0044] Add polyethylene glycol and an appropriate amount of absolute ethanol to the aqueous phase solution in step 1, and then add titanium dioxide, hydroxyapatite and sodium carboxymethylcellulose after stirring, and stir until a uniform dispersion is formed; the appropriate amount of absolute ethanol is Refers to 30% of the formula volume of absolute ethanol;

[0045] step 3

[0046] Add shellac to the remaining amount of absolute ethanol under stirring conditions, stir for 120 minutes until the solution is cool and lemon-colored, stop stirring, then add the dispersion prepared in step 2 to the solution, and stir for another 30 minutes to obtain required oral smear; the deh...

Embodiment 5

[0047] Example 5 Whitening Effect Verification

[0048] The oral smears of Example 1, Example 2, Example 3, Example 4, Comparative Example 1 and Comparative Example 3 were verified for whitening effect, and the verification method was as follows:

[0049] 1. select the enamel block that is evenly stained, and the L* value is between 30 and 45, based on L*, randomly divide into 6 groups (4 groups of embodiment groups, 2 groups of comparative example groups), so that the L* value between each group The sum of the values ​​is roughly the same.

[0050] 2. Use the X-Rite SP 64 colorimeter to measure the enamel color of each group, record the L* value, and mark it as L*pre.

[0051] 3. Each group uses the corresponding test smear liquid to directly apply a layer of oral smear liquid evenly on the enamel of the blackened cattle teeth. After standing at room temperature for 30 minutes, rinse the smear liquid on the cattle teeth with water, dry the water with paper towels, and let it...

Embodiment 6

[0059] Example 6 Verification of anti-allergic effect

[0060] The oral smear of embodiment 1, embodiment 2, embodiment 3, embodiment 4 and comparative example 2 is carried out anti-allergic effect verification, verification method is as follows:

[0061] 1. Making dentin samples: freshly extracted bovine incisors were cut and polished to make 25 dentin blocks with a size of about 5mm×5mm×2mm, which were treated with acid etching and demineralization, and observed under a polarizing microscope to ensure Dental tubules well exposed.

[0062] 25 dentin samples were randomly assigned to 5 groups prepared with 5 oral smears according to the formulas of Comparative Example 2 and Examples 1-4, 5 dentin samples in each group.

[0063] 2. Partitioning: stick half of the area (about 5mm×2.5mm) of the dentin sample with adhesive tape as the non-treatment area, and the other half area (about 5mm×2.5mm) as the experimental treatment area for smearing liquid.

[0064] 3. Smear treatment:...

Abstract

The invention discloses an anti-allergic and whitening oral liniment. The anti-allergic and whitening oral liniment is prepared from, by weight percentage, 0.1-5% of whitening agent, 0.1-10% of anti-allergic agent, 0.1-2% of covering agent, 10-30% of film-forming agent, 50-80% of solvent, 0.01-0.5% of preservatives, 0.01-5% of buffer stabilizer, 0.01-1.5% of flavoring agent and deionized water. The anti-allergic and whitening oral liniment saves a mouth gag and can be directly applied to teeth to rapid form films to achieve the dual effects of tooth whitening and allergy resistance; meanwhile, the formed films can be tightly adhered to tooth surface and avoid falling off and dissolving under chewing movement. When applied to the teeth, the anti-allergic and skin whitening oral liniment can avoid foreign body sensation and sticky feeling, thereby achieving long-term protection of healthy and white teeth.
