Description

A plaque-decomposing essence Technical Field

[0001] This invention relates to the field of dental plaque removal technology, and more particularly to a dental plaque decomposition and visualization essence. Background Technology

[0002] Dental plaque is a soft, unmineralized bacterial colony encapsulated in a matrix, adhering to each other, or adhering to the tooth surface, interdental spaces, or restoration surface. It is generally composed of bacteria, exfoliated cells, and food debris, and cannot be washed away by water or rinsed off. Dental plaque can lead to various oral health problems such as tooth decay, gingivitis, and periodontal disease. It is also characterized by cloudy, light-colored white patches that develop later in life due to poor oral hygiene.

[0003] When the amount of dental plaque is small, it is difficult to observe with the naked eye, and existing technology usually uses plaque indicators to show it.

[0004] Dental plaque indicator lenses are used to highlight areas of plaque accumulation by staining. However, these developing lenses have several drawbacks:

[0005] (1) Difficult to remove: The dyes used for coloring are difficult to remove completely and usually require professional dental cleaning methods such as sandblasting.

[0006] (2) Staining problem: These coloring products will not only stain teeth, but also fillings, crowns and braces, causing aesthetic problems;

[0007] (3) Collateral damage: The sandblasting cleaning method used to remove stains from color-developing products is abrasive. Excessive force during sandblasting may roughen the enamel surface, making it more susceptible to plaque and stains in the future.

[0008] Dental plaque removal is usually achieved through teeth cleaning. Teeth cleaning uses an ultrasonic scaler that vibrates up and down when it comes into contact with tartar and plaque, removing them through mechanical stimulation. However, teeth cleaning usually only removes visible plaque, leaving behind the deeper plaque that is most pathogenic, thus failing to prevent periodontal disease. Furthermore, teeth cleaning can cause tooth sensitivity.

[0009] Another drawback of teeth cleaning is that it is highly specialized and cannot be performed by the patient themselves.

[0010] Based on this, existing technologies disclose toothpaste that displays or removes dental plaque.

[0011] For example, Chinese patent CN107095797A discloses a toothpaste for detecting plaque and its preparation method. This method involves adding a colorant to the toothpaste to achieve a color-developing effect, but plaque removal relies on the abrasive action of the toothpaste. While this method does have both color-developing and plaque-removing effects, it does not actually decompose plaque, and the abrasive action of the toothpaste can easily roughen tooth enamel.

[0012] Chinese patent CN105769609 B discloses a toothpaste composition with antibacterial, stain-removing and whitening functions. It uses multiple enzymes to remove dental plaque, but it still requires friction to remove it, which damages the enamel and does not show any effect. Therefore, consumers cannot clearly know the effect during daily use.

[0013] Therefore, there is a need for a product that can display and help remove dental plaque while avoiding the aforementioned drawbacks.

[0014] Summary of the Invention

[0015] In view of this, the present invention provides a plaque-decomposing and revealing essence. The essence of the present invention can create an alkaline environment that is beneficial to dental health, reveal and decompose soft plaque and dental plaque on the tooth surface, lighten tooth stains on the tooth surface, gently protect tooth enamel and dentin, and has a repairing effect on teeth.

[0016] The plaque-decomposing and revealing essence of this invention comprises the following raw materials by weight percentage:

[0017] Water 10-95%, peroxide 0.1-40%, ammonia 0.1-30%, polyacrylic acid 0.1-20%, potassium hydroxide 0.1-30%.

[0018] Preferably, the peroxide is either hydrogen peroxide or ammonium peroxide.

[0019] Preferably, the plaque-decomposing essence also contains an antibacterial agent; the method for preparing the antibacterial agent is as follows:

[0020] (1) Mix Zanthoxylum nitidum, tea leaves, Sargassum fusiforme, and Viola yedoensis in a mass ratio of 2:3:2:1;

[0021] (2) Add 6 to 7 times the amount of 70% ethanol, heat and reflux for 1 to 2 hours, filter, concentrate the filtrate under reduced pressure, and dry at low temperature to obtain the antibacterial agent.

[0022] More preferably, the amount of the antibacterial agent added is 2-3% of the plaque decomposition revealing essence.

[0023] Preferably, the plaque-decomposing extract further contains calcium phosphate and sodium tripolyphosphate.

[0024] More preferably, the amount of calcium phosphate added is 0.5-1% of the plaque decomposition and display essence; and the amount of sodium tripolyphosphate added is 0.8-1.5% of the plaque decomposition and display essence.

[0025] Another objective of this invention is to provide a method for preparing a plaque decomposition and visualization essence: mixing raw materials in a certain proportion, stirring evenly, sealing and storing to obtain the plaque decomposition and visualization essence.

[0026] The plaque-decomposing essence prepared by this invention is a colorless and transparent liquid that can chemically decompose organic matter. It has a significant decomposition effect on tooth enamel, stains, and plaque, and can also decompose bacteria that cause tooth decay and gingival inflammation, such as Streptococcus mutans and Lactobacillus. It can directly remove plaque without the need for external force and can whiten teeth. It provides a beneficial condition for the oral cavity to promote tooth self-repair and remineralization of the tooth surface.

[0027] Tooth remineralization is based on the principle that ion exchange can occur between teeth and saliva. By artificially increasing the concentration of mineral ions such as calcium, fluoride, and phosphorus in the external environment of the tooth, the concentration of mineral ions in the external environment of the tooth is higher than that inside the tooth enamel. As a result, the mineral ions will penetrate into the enamel, causing the demineralized and softened enamel to remineralize.

[0028] Furthermore, the raw materials of this application also contain an antibacterial agent, which is a plant-based ingredient that can more effectively remove bacteria in the oral cavity and also freshen breath.

[0029] Furthermore, calcium phosphate is added to the raw materials of this application. The presence of plaque, bacteria, and other components in the oral cavity creates an acidic environment, leading to calcium loss. The essence, after breaking down plaque and bacteria, provides beneficial conditions for tooth surface remineralization. Even without the addition of calcium phosphate, it can promote the redeposition of calcium and phosphorus in the oral cavity to repair tooth enamel. Adding calcium phosphate accelerates the enamel repair process of the essence.

[0030] Furthermore, this application also adds sodium tripolyphosphate to further enhance the whitening effect of the essence.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] This invention provides a plaque-decomposing and revealing essence, using water, peroxide, ammonia, polyacrylic acid, and potassium hydroxide as raw materials. The peroxide decomposes anaerobic bacteria and plaque; the polyacrylic acid increases the liquid's viscosity; and the ammonia and potassium hydroxide neutralize the acidity of the oral cavity and provide an alkaline environment. The plaque-decomposing and revealing essence of this invention contains peroxide, which has oxidizing properties and can adhere to the surface of plaque. In an alkaline environment, it rapidly decomposes plaque and bacteria, producing foam that reveals the plaque. This overcomes the drawback of existing plaque revealing agents being difficult to remove. The essence of this invention creates an alkaline environment beneficial to dental health, revealing and decomposing plaque and soft deposits on the tooth surface, fading tooth stains, gently protecting tooth enamel and dentin, and possessing repairing properties for teeth, while effectively preventing tooth decay.

[0033] Figure 1 shows the changes in the tooth surface before and after using the plaque decomposition and display essence described in Example 1 of the present invention. Detailed Implementation

[0034] This invention provides a plaque-decomposing and revealing essence, comprising the following raw materials by weight percentage:

[0035] Water 10-95%, peroxide 0.1-40%, ammonia 0.1-30%, polyacrylic acid 0.1-20%, potassium hydroxide 0.1-30%.

[0036] The peroxide is either hydrogen peroxide or ammonium peroxide.

[0037] Furthermore, the plaque-decomposing essence also contains an antibacterial agent; the method for preparing the antibacterial agent is as follows:

[0038] (1) Mix Zanthoxylum nitidum, tea leaves, Sargassum fusiforme, and Viola yedoensis in a mass ratio of 2:3:2:1;

[0039] (2) Add 6 times the amount of 70% ethanol, heat and reflux for 2 hours, filter, concentrate the filtrate under reduced pressure, and dry at low temperature to obtain the antibacterial agent.

[0040] The plaque-decomposing essence also contains calcium phosphate and sodium tripolyphosphate.

[0041] The preparation method of the plaque decomposition and visualization essence includes the following steps: mixing the raw materials in proportion, stirring evenly, sealing and storing to obtain the plaque decomposition and visualization essence.

[0042] The present invention will be further described below with reference to the embodiments. In the specific embodiments of the present invention, the preparation method of the dental plaque decomposition and display essence is the same, the difference lies in the composition and proportion of raw materials.

[0043] Examples 1-12

[0044] The composition and proportion of the raw materials in Examples 1 to 12 are shown in Table 1. The proportions of the raw materials in the table are all weight percentages (%).

[0045] Table 1

[0046] Comparative Examples 1-3

[0047] The composition and proportion of the raw materials in Comparative Examples 1 to 3 are shown in Table 2. The proportions of the raw materials in the table are all weight percentages (%).

[0048] Table 2

[0049] The following experiments were conducted using the plaque decomposition revealing extracts from Examples 1-12 and Comparative Examples 1-3:

[0050] Three hundred subjects were randomly divided into 15 groups: experimental groups 1-12 and control groups 1-3. The experimental groups used the extracts prepared in Examples 1-12, while the control groups 1-3 used the extracts prepared in Comparative Examples 1-3.

[0051] The specific method is as follows: Apply the essence to the tooth surface (0.5–3 mm), observe the plaque appearance, and then apply it back and forth for 2 minutes, or place the essence in a special dental tray (the tray only serves as a container for the essence, allowing it to soak the teeth) and wear it for 10 minutes before rinsing to remove the essence. Repeat this process for 30 consecutive days (once a day). During this period, 15 groups of participants brushed their teeth twice a day using the same toothpaste. The removal of plaque, the antibacterial rate, and the change in enamel color ΔL* (the calculated average value) were measured.

[0052] The calculation method for the reduction rate of dental plaque index is as follows: (1)

[0053] The method for calculating the difference in L* value before and after brushing teeth is as follows: (2)

[0054] ΔL*=L* 刷牙后 -L* 刷牙前 (2)

[0055] The antibacterial effect (antibacterial rate) of different serums against oral pathogens was tested in accordance with QB / T 2738-2023 "Evaluation Method for Antibacterial and Bacteriostatic Effects of Daily Chemical Products".

[0056] The results are shown in Table 3.

[0057] Table 3

[0058] Participants using the plaque decomposition and display essence prepared in Example 1 were selected. Changes in the cervical, middle, and incisal edges of their teeth were measured using a digital spectrophotometer before the experiment and on day 14. Shade was classified as a*, b*, and L* according to the CIE system. a* and b* represent the hue saturation (regional) tooth shade along the green-red and blue-yellow axes of the visible electromagnetic spectrum, respectively, and the lightness of the L* value (ranging from 0 (black) to 100 (white)). ΔL* represents the change in lightness. The test results for one tooth are shown in Table 4.

[0059] Table 4

[0060] The calculation method for Δ in Table 4 is shown in equation (3):

[0061] Experimenters who used the plaque decomposition and display essence prepared in Example 1 were selected, and the changes in the smoothness of their tooth surface were observed after 2 months. The results are shown in Figure 1.

[0062] As can be seen from the figure, the plaque decomposition and visualization essence of this application can repair tooth enamel and significantly improve the smoothness of the tooth surface.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
