The composition can be developed into products such as mouth wash, oral spray and solid beverage.

Description

Traditional Chinese medicine composition for inhibiting formation of dental plaque, preparation method and application thereof
Technical Field
The invention relates to the technical field of medicines, and particularly relates to a traditional Chinese medicine composition for inhibiting dental plaque formation, a preparation method and application thereof.
Background
Dental plaque is a soft, unmineralised bacterial biofilm formed by a large number of bacteria that colonise the tooth surface, between teeth or on the surface of dentures (dentures, restorations), together with exfoliated oral epithelial cells and food debris, has strong adhesion and is difficult to remove by mouth rinsing and tooth brushing. The growth, reproduction and acid production of bacteria in the bacterial plaque can remove the enamel, which is a common cause of tooth diseases such as periodontal disease, decayed tooth and the like. In addition, plaque can calcify to form calculus, resulting in bad breath. Since bacterial growth is continuous, the key to plaque control is the frequent inhibition of harmful oral bacteria, particularly anaerobic bacteria such as streptococci and filamentous bacteria.
In order to inhibit the formation of dental plaque, some collutory and toothpaste products added with chemical pharmaceutical ingredients such as alcohol, oxidant, lysozyme, antibiotics and the like appear in the market, and can effectively reduce the quantity of pathogenic microorganisms in the oral cavity. However, the perceived comfort and acceptance of the patient is reduced due to the corrosive, irritating odor and staining of the teeth of some formulations. Therefore, there is a need to develop a more safe and effective dental plaque inhibitor.
In view of this, the invention is particularly proposed.

Example 1
Screening the bacteriostatic action of common traditional Chinese medicines on streptococcus mutans:
preparing Streptococcus mutans into 104The method comprises the following steps of/mL of bacterial suspension, using tetracycline as a positive control, using deionized water as a negative control, adding 250 mu L of clarified filtrate obtained by concentrating water extract and alcohol extract of various plant materials into the bacterial suspension, placing the bacterial suspension in a constant-temperature shaking table at 37 ℃ for culturing for 12h, diluting mixed bacterial liquid in a gradient manner, coating the mixed bacterial liquid, culturing the bacterial liquid in a biochemical incubator at 37 ℃ for 24h, counting bacterial colonies, calculating the bacterial inhibition rate, wherein the bacterial inhibition rate is (the bacterial colony number of an experimental group-the bacterial colony number of a negative control group)/the bacterial colony number of a control group, and performing single-factor variance analysis and multiple comparison analysis on the difference between the groups by using SPSS (Sphings system) to find that the two extracts of other plant materials except chrysanthemum, boat-fruited sterculia, lophatherum gracile and clove can inhibit the proliferation of the streptococcus mutans (see Table 1).
TABLE 1 bacteriostasis rates of different plant materials
Figure BDA0002452944960000061
Figure BDA0002452944960000071
Compared with the negative control, the method has the advantages that,p<0.05,**p is less than 0.01; compared with the water extracting solution,#p<0.05。
as can be seen from table 1 above, compared with the negative control, the difference of the bacteriostatic ratio of the extract of five plant materials is extremely significant, and the bacteriostatic ratio of the alcohol extract is usually higher than that of the corresponding water extract, and the extract is sequentially arranged by houttuynia cordata, dandelion, mint, honeysuckle and liquorice.
The traditional Chinese medicine composition for inhibiting dental plaque formation comprises the following components in parts by weight: 1 part of houttuynia cordata extract, 1.5 parts of dandelion extract, 2 parts of mint extract, 3 parts of honeysuckle extract and 1.5 parts of liquorice extract.
The bacteriostatic effect of the traditional Chinese medicine composition for inhibiting dental plaque formation provided in this example was evaluated:
evaluation of bacteriostatic effect referring to fig. 1, the lowest effective inhibitory concentration of each plant extract and composition in fig. 1 for inhibiting the proliferation of streptococcus mutans is shown as statistical difference in letters. As can be seen from FIG. 1, the lowest effective inhibitory concentration of the composition obtained by combining the 5 Chinese medicinal extracts is obviously lower than that of the single component, which indicates that the effective inhibitory effect can be achieved by combining the 5 different Chinese medicaments.
The effect of the traditional Chinese medicine composition for inhibiting dental plaque formation provided in this example was evaluated:
80 healthy adult volunteers were recruited, smokers and patients with severe dental disease were excluded, and plaque formation evaluation test was performed for 2 weeks. During the experiment, the consumption of sweets such as candies and the like and the drinking of colored beverages such as strong tea, coffee and the like are avoided, other medicines are forbidden, the subjects brush their teeth once respectively before getting up in the morning and sleeping at night, and the toothpaste is common toothpaste and is provided by a subject group. Five teeth were thoroughly cleaned supragingivally before the experiment for each subject, at which the Plaque Index (PI) was calculated to be 0.
The first group is to rinse the mouth with clear water twice after each meal
Secondly, the mouth wash is carried out twice after each meal by using the common Jinkouxin brand medicinal sign mouthwash (the effective components are chlorhexidine gluconate and metronidazole)
Third, rinsing with herba Houttuyniae extractive solution twice after each meal
Fourthly, gargling twice with dandelion extract after each meal
The fifth group, gargling twice with herba Menthae extract after each meal
Sixthly, gargling twice with honeysuckle extract after each meal
Seventh group, rinsing twice with Glycyrrhrizae radix extractive solution after meals
Eighth group, rinsing twice with the extract composition after each meal
After 14 days each examined tooth surface was stained by chewing a plaque indicator and 5 tooth Plaque Indices (PI) were calculated.
Evaluation of the effect of inhibiting plaque formation referring to fig. 2, the effect of gargling each plant extracts and compositions on plaque formation in fig. 2 is shown with statistical differences in letters. As can be seen from fig. 2: the plant extract provided by the embodiment of the invention has no difference with the dental plaque index of the chemical preparation mouthwash, and compared with a clear water control, the plant extract can effectively reduce the dental plaque index, and the dental plaque index of the compound is the lowest, which indicates that the plant extract has a synergistic effect.
