Description

Oral care composition for treating dry mouth and application of oral care composition in toothpaste

Technical Field

The invention relates to the technical field of oral care products, in particular to an oral care composition for treating xerostomia and application thereof in toothpaste.

Background

Saliva plays an important role in lubricating and digesting food, cleaning the oral cavity, and protecting the oral cavity from chemical, mechanical, and infectious factors. Normal saliva contains antibodies, enzymes and buffers. It prevents the progression of caries by maintaining the normal pH of the oral environment, rendering it neutral, limiting the production of acid due to sugar degradation. Salivary enzymes act at the beginning of food digestion. Saliva also plays an important role in taste and speech.

Insufficient salivation can lead to dry mouth. Xerostomia is not clinically common, and the incidence rate is higher especially for the elderly. Other factors such as radiation therapy, antidepressants, and also anticholinergics, antiallergic drugs, antihistamines, antispasmodics, decongestants, and diuretics are more commonly used to cause dry mouth. Narcotic analgesics, chemotherapeutic drugs such as doxorubicin, have been reported to cause xerosis.

When the mouth is dry, food and bacteria adhere to the tooth surface, promoting plaque formation. Oral pH is also reduced, thus increasing the risk of caries. The oral flora can be changed, and the proportion of pathogenic bacteria related to the occurrence of caries, such as streptococcus mutans and actinomycetes, is obviously increased when being normal. Because caries in radiation therapy requires removal, poor health and infection can lead to the development of xerostomia syndrome. Chronic gingival infection can cause marginal periodontitis. Food particles enter the gap between the gums and teeth, providing for the growth of bacteria, which can develop into bad breath.

The dry mouth problem affects the number and choice of food consumed by the patient and increases the risk of insufficient nutritional intake. Loesche et al reported that these patients are more likely to avoid eating crunchy foods such as vegetables, dry foods such as bread, viscous foods such as peanut oil, and the like, when chewed. Therefore, the development of the oral care composition for treating the dry mouth has great social significance and market prospect.

Patent application publication No. CN105311404A relates to a formula for treating senile xerostomia, and the formula components and respective weights are as follows: 15 g of dendrobium, 15 g of polygonatum, 18 g of Chinese yam and 12 g of sealwort. Can effectively stimulate the secretion function of salivary glands and play a role in promoting the salivary glands to secrete saliva.

Patent publication No. CN101678217B relates to a composition for the treatment of xerostomia and conditions related thereto comprising olive oil, trimethylglycine and xylitol, which has a very good effect in increasing unstimulated saliva flow or alleviating the symptoms of xerostomia and improving the quality of life of the patients.

Patent application publication No. CN103561719A relates to an oral composition comprising an extract obtained from araliaceae, zingiberaceae, labiatae, leguminosae, solanaceae, punicaceae, asteraceae or a mixture thereof, having an effect of alleviating dry mouth.

In the process of treating xerostomia, the prior art often adopts a method of stimulating salivary secretion to increase the amount of saliva in the oral cavity, thereby relieving the xerostomia. Because of the short duration of action of the oral care composition in the oral cavity and the low residual levels of active in the oral cavity, the therapeutic effect of this method is not significant, especially for some people with hyposalivation. The prior art oral care compositions have a short duration of action in the oral cavity and low residual levels of actives; only plays a role in stimulating salivary secretion, and has no obvious effect on the population with hypofunction of salivary glands.

[ Effect verification of example ]

Efficacy of the composition of the invention on adult populations suffering from symptoms of hyposalivation and xerostomia.

Test objects: a total of 80 subjects were recruited and enrolled from the general population between the ages of 50-67. All objects met the following conditions:

self-evaluation with xerostomia;

unstimulated saliva flow equal to or less than 0.2 ml/min

Subjects volunteered to use only the coordinator-specified product at each stage of the study.

Subjects volunteered to assist in completing all of the follow-ups required for this study.

The test method comprises the following steps:

each subject was interviewed by the coordinator using the xerostomia questionnaire to learn the dry mouth symptoms of the subjects. The questionnaire was as follows:

the subjects were randomly divided into four groups. Each group consisted of 20 individuals, and the products of example 1, example 3, example 4, and example 5 were used, respectively. Brushing teeth in the morning and evening for 2 times a day according to a normal tooth brushing mode.

Before the test toothpaste is used by the subject, the dry mouth condition of the subject is recorded by a coordinator according to a questionnaire, and a baseline measurement is made.

On day 8 of the test product use by the subjects, all subjects returned to the study center. The coordinator recorded the dry mouth condition of the subject, and possible side reactions, according to the questionnaire.

The effect of the product on dry mouth treatment was evaluated by comparing the dry mouth of the subjects before and after the test product was used.

And (3) testing results:

a total of 78 subjects from 80 of the experiments completed all the tests. The other 2 reasons for exit are not product dependent. No adverse reaction is found in the experimental process. The test results are shown in the following table.

From the test results, it can be seen that the effect of adding both of the enzymes is much better than that of adding only the bio-enzyme in the comparison between the example 1 (enzyme + Chinese herbal medicine) and the example 3 (adding only the bio-enzyme), and in addition, the effect of adding both of the enzymes is much better than that of one of the Chinese herbal medicines in the comparison between the example 1 (enzyme + Chinese herbal medicine) and the example 4 (only Chinese herbal medicine). The product added with the biological enzyme and the Chinese herbal medicine extract has the effect of treating the dry mouth, which is obviously superior to the product only added with the Chinese herbal medicine extract or the biological enzyme. The product without adding biological enzyme and Chinese herbal medicine extract has almost no treatment effect.

Therefore, the composition for treating the dry mouth, which is prepared from the biological enzyme and the Chinese herbal medicine extract, has a remarkable effect and can relieve the dry mouth condition of the dry mouth population.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, which fall within the scope and spirit of the above description.
