Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for prevention, improvement or treatment of oral diseases containing an extract as an active ingredient,

TECHNICAL FIELD The present invention relates to a composition for preventing, ameliorating or treating oral diseases, and more particularly, to a composition containing an anti-sea extract as an active ingredient.

The anti-sea extract according to the present invention inhibits the growth of oral bacteria, the effect of inhibiting the acid production of oral bacteria, the effect of inhibiting the biofilm formation of oral bacteria, and the biofilm formation of oral bacteria on the surfaces of artificial teeth and natural teeth .

The environment of the oral cavity is suitable for the growth of bacteria by nutrition and physiology. Because many bacteria are always present, the incidence of oral diseases is very high. Dental caries and periodontal disease are typical oral diseases caused by these oral bacteria.

Translucent, hard, milky white material that covers the surface of the head of a tooth and protects the tooth dentin is called tooth enamel or enamel. It is called dental caries that the tooth enamel is damaged by the acid generated by the decomposition of sugar or starch by bacteria living in the oral cavity, and tooth decay occurs.

Periodontal disease is often referred to as taste, depending on the degree of disease gingivitis (gingivitis) and periodontitis (periodontitis) is divided into. It is a relatively light and fast-acting periodontal disease called gingivitis that is limited to gingiva or soft tissue, and it is called periodontitis when the inflammation progresses to the gums and the gums.

There is also a V-shaped gap between the gum (gums) and the teeth. Periodontal disease refers to the attack of germs on the lower part of the gum line of the sulcus, damaging the periodontal ligament and adjacent tissues. As the inflammation progresses and more tissue is damaged, the groove develops into a periodontal pocket, and the more the periodontal disease becomes, the deeper the depth of the periodontal pocket becomes. As the periodontal ligament becomes deeper, periodontal ligaments become inflamed and bone loss may occur.

Typical oral bacteria include Streptococcus mutans , Porphyromonas gingivirus, gingivalis and Prevotella intermedia ). The present invention provides a composition for preventing, ameliorating or treating oral diseases through inhibition of S. mutans .

A biofilm is a layer in which microorganisms such as bacteria collect to form a single layer.

Biofilms can be made on a solid surface, or on the surface or inside of a liquid. When a microorganism forms a biofilm, the microorganism can more effectively capture and grow the nutrient, and the adhesion to the surface of the material also increases.

S. mutans It also forms a biofilm on the tooth surface. S. If mutans biofilm formation S. that becomes more and more difficult elimination of mutans, S. the activity of the mutans is enhanced. Therefore, S. The inhibition of biofilm formation of mutans can also inhibit the development of tooth decay.

Meanwhile, the objection of the present invention will be briefly described below.

In contrast, there are anti-Japanese, such as Ho Daei, Annam, and Dae Dong, and in Korea, Sterculia scaphigera Wall. In China, Sterculia lychnophora Hance: 大海 樹). In Japan, it was not found in process medicines.

There is no smell, and if you chew it for a long time, it is viscous, the taste is sweet and the quality is cold.

In addition, the opposite is done by removing the heat by lowering the lungs. Dry cough, sore throat, sore throat, osteoporosis, osteoporosis, nosebleed, stigma, ocular hypertension, toothache or hemorrhoids. Weak diarrhea and hypotensive effects were reported with pharmacological actions.

As for the prior art related to the objection of the present invention, skin whitening and antioxidant compositions containing an extract are disclosed in the Korean Patent Registration No. 10-0930592.

However, the above-mentioned document relates to a skin whitening and antioxidative use of an extract as a countermeasure, and describes a whitening cosmetic composition composed of an anti-seaweed extract and an organic solvent fraction, and a description of the efficacy of the anti- I can not.

To date, the effects of antipyretic, antipyretic, antipyretic, whitening, or antioxidant effects have been known. However, the efficacy of anti-inflammatory drugs for oral diseases has not been reported.

Accordingly, the present inventors have made the present invention to provide a composition containing an anti-sea extract as an active ingredient and having efficacy in preventing, ameliorating or treating oral diseases.
