Description

Oral composition comprising amaranth extract}

The present invention relates to an oral composition, and more particularly, to an oral composition for preventing or treating oral diseases.

As the concept of dental health changes to the concept of social life, interest in oral health is increasing, and interest in bad breath, which is an important obstacle to interpersonal relationships in social life as well as prevention and treatment of oral diseases, is also increasing.

Tooth tissue is composed of enamel, cementum, and dentin. The outside of the tooth exposed to the outside is covered with enamel, and the outside of the tooth root located within the alveolar bone is covered with cementum, and dentin exists inside these. Dentin has microscopic tubes called dentinal tubules distributed throughout the dentin.

The symptom of sensitive teeth is that the dentin part of the exposed tooth is felt sensitive when it comes in contact with cold air or irritating food. The fundamental cause of this symptom is that many tubules present in the dentin of the tooth are exposed to the outside. Symptoms of sensitive teeth can range from mild symptoms to intense and persistent pain. In addition, because teeth do not regenerate due to their nature, taking painkillers or anti-inflammatory drugs is not a fundamental solution to the phenomenon of sensitive teeth, so various treatments have been developed to alleviate the symptoms of sensitive teeth.

There are two main treatments for sensitive teeth: dentinal tubule sealing and pulp nerve desensitization. The dentinal tubule sealing method is a method of restoring lost enamel by filling the exposed dentinal tubules with resin or applying fluoride, while the pulp nerve desensitization method regulates nerve transmission by the appropriate ratio of sodium ions and potassium ions. This is a treatment that prevents nerves from feeling pain by artificially increasing the potassium ion content. However, because this specialized treatment requires the hassle of going to the dentist, toothpastes for sensitive teeth that can treat or prevent sensitive teeth in everyday life are being sold.

These toothpastes contain active ingredients useful for the above two treatment methods. However, among these, toothpastes that contain potassium phosphate and other ingredients to show the effect of desensitizing the pulpal nerve have a long period of effect, about 15 days, so toothpastes that have the effect of dentinal tubule sealing, which shows the effect relatively quickly, are preferred. there is.

However, in the case of Sirin Professional toothpaste, which utilizes the conventional dentinal tubule sealing effect, it contains fine powder of the active ingredient to seal the dentinal tubules, but it is usually quickly diluted during the toothbrushing process and most of it is washed away during the rinsing process with water. There was a problem in that the customs tube was not sealed and was exposed again.

Meanwhile, the causes of bad breath are largely classified into intra-oral causes, extra-oral causes, and psychogenic causes. Among them, oral causes account for about 80-90% of the causes of bad breath, resulting in decreased saliva volume, increased saliva consistency, and hydrogen ion concentration buffering capacity. decrease, increase in the amount and activity of oral microorganisms, tongue coating attached to the back of the tongue, and oral diseases such as untreated dental caries and periodontal disease.

Meanwhile, among oral diseases, dental caries and periodontal disease are known to cause various clinical symptoms such as pain, impaired chewing function, destruction of periodontal tissue, and bad breath, and are the main factors causing tooth loss. Changes in eating habits are the cause of dental caries. The number of factors is increasing.

It is a method of suppressing the growth of oral pathogens that live in the dental plaque and cause dental caries, periodontal disease, and bad breath. Various types of antibacterial agents, including antibiotics with sterilizing and bacteriostatic effects on these bacteria, are used to treat dental caries, periodontal disease, dental pulp, and other diseases. It has been developed as a treatment and inhibitor of periapical infection.

However, antibiotics have the disadvantage of being difficult to use long-term and being used only as a treatment because they can cause systemic side effects on our body and the emergence of resistant bacteria in the oral cavity and bacterial turnover. In addition, fluoride, an antibacterial agent, has a clear cavity prevention effect, but its effect on periodontal, dental pulp, or periapical diseases has not yet been reported. In addition, antibacterial agents used in toothpaste, mouthwash, and other mouthwashes include sanguinarine, listerine, peroxide, and chlorhexidine. Sanguinarine is effective against bacteria in the oral cavity. Listerine's main ingredient is alcohol, so it has a temporary effect or a slight bacteriostatic effect in the oral cavity, but it may also have a harmful effect on tissues when used for a long period of time. Peroxide, which has recently been added for whitening effect, has a toxic effect on bacteria, but at the same time, it has a toxic effect on human tissue, so not only is there a safety problem, but sometimes bacteria resistant to peroxide emerge. do. In addition, chlorhexidine is known to be the best among the agents known to date as a preventive and treatment agent for periodontal disease in addition to inhibiting plaque formation. However, it has the side effects of tissue irritation, tissue staining and degeneration, and especially a strong and irritating taste. In addition, there are disadvantages that it cannot be used for long periods of time for treatment or especially prevention purposes, such as it can cause bacterial dysbiosis, and its use in pregnant women is limited due to its carcinogenic properties (Contemporary Periodontics [ed. R.J. Genco et. al.], p161-169, p368-369, p433, C.V. Mosby Company, St. Louis, 1990).

Accordingly, the present inventors conducted research to derive a natural material that is effective in preventing and improving oral diseases such as dental caries, periodontal disease, bad breath, and sensitive teeth without concerns about the above-mentioned side effects.

Republic of Korea Patent Publication No. 10-2015-0050995

Accordingly, the present inventors completed the present invention by confirming that amaranth extract has excellent effects on oral diseases.

Therefore, the purpose of the present invention is to provide an oral composition containing amaranth extract as an active ingredient.

Additionally, an object of the present invention is to provide an oral product containing the composition.

As an embodiment to solve the above problem, the present invention provides an oral composition containing an amaranth ( Amaranthus ) extract as an active ingredient.

In the present invention, the composition may be used to prevent or treat oral diseases.

In the present invention, the oral disease is a comprehensive concept that includes, but is not limited to, bad breath, sensitive teeth, dental caries, gingivitis, periodontitis, oral mucosal ulcer, and periapical disease.

In the present invention, the oral disease may preferably be syrin.

In addition, the term "alleviation" used herein means reducing or alleviating the symptoms of oral diseases such as those described above, and can be understood as a broad concept including improvement, prevention, treatment, etc.

Additionally, the term “improvement” used in this specification can be understood as a broad concept meaning to restore symptoms to close to their original state by treating oral diseases, etc.

The term "bad breath" used in this specification is not limited to this, but causes bad odor due to the decomposition of substances produced by microorganisms in the oral cavity due to acquired systemic diseases or when proteins and food residues in saliva are decomposed. It can occur by producing substances that The oral microorganisms that are the primary cause of bad breath are, but are not limited to, Streptococcus genus, Porphyromonas genus, Actinomyces genus, Actinobacillus genus, etc. This can be.

As used herein, the term “dental caries” is not limited thereto, but means that teeth are damaged by bacteria in the oral cavity, resulting in cavities. For example, plaque, a biofilm formed on the surface of teeth, may be the cause. The oral bacteria may be of the Streptococcus genus, Porphyromonas genus, etc.

The terms “gingivitis” and “periodontitis” used in this specification are, but are not limited to, conditions for the growth of bacteria such as Streptococcus and Porphyromonas present in subgingival plaque. When it forms, it can cause infection in the soft tissue of the gingival area and develop into periodontal disease such as gingivitis or periodontitis, which is an oral disease that causes inflammation of the gums.

As used herein, the term "oral mucosal ulcer" is also called stomatitis, but is not limited to this, and is not limited to oral mucosa (skin, gums, lips, inner cheek) due to infection by oral bacteria, viruses, fungi, etc. etc.) refers to a disease in which inflammation occurs, and the bacteria may be bacteria of the Streptococcus genus or Porphyromonas genus.

The term “periapical disease” used herein is not limited thereto, but may mean inflammation occurring at the root end of the tooth. Periapical diseases include periapical cysts, periapical abscesses, and periapical osteosarcomas, but are not limited to these and can be caused by bacteria such as Streptococcus and Porphyromonas .

The term "sirini" used herein is not limited thereto, but refers to any phenomenon in which sharp, temporary or persistent pain appears in response to external stimuli, independently of cavities or other pathological causes. The above-mentioned external stimulus usually refers to temperature stimulus, and symptoms are usually reported in response to cold temperature stimulation, but pain may also appear in hot temperature. In addition to temperature stimulation, pain can also occur due to stimulation such as drying of the teeth, contact with external substances, or osmotic pressure from sweet or sour foods. This may appear throughout the entire tooth, or may be limited to specific areas such as the upper or lower jaw, or the right or left, and may be accompanied by dentine hyperesthesia, caries, and pulp inflammation.

Exposure to the entrance of the dentinal tubules can be considered the cause of these symptoms.

When enamel or cementum is destroyed and the entrance of the dentinal tubule is exposed to the outside, stimulation is transmitted to the pulp by the cell protrusions, nerves, and dentinal fluid of the dentinal tubule, causing pain.

The inventors of the present invention completed the present invention by confirming that the amaranth extract has a property that allows it to be absorbed into the tooth surface and/or dentinal tubules, and thus has an excellent effect in preventing and alleviating the symptoms of toothache.

As used herein, the term "extract" refers to an extract obtained by extraction treatment of amaranth, a diluted or concentrated liquid of the extract, a dried product obtained by drying the extract, a crude product or purified product of the extract, or a mixture thereof, etc. This includes the extract itself and all formulations of the extract that can be formed using the extract.
