Background

In recent years, the substitution of drinking water for beverages in children and adolescent groups is rare and growing with increasing economic levels. The parents fail to achieve satisfactory effects on the oral hygiene of children and the oral cavity propaganda and education of medical care personnel, and the milk tooth demineralization phenomenon caused by the beverage is common. This has been intensively studied and discussed in a number of studies to achieve its substantiating effect, and this study was used as a supplement to many of the existing studies to simulate oral ingestion of beverages in an extraoral mold as much as possible, and to verify the demineralizing effect of the beverages on enamel and the protective effect of galodoraf on it.

There have been many studies on the demineralization of enamel by beverages, but the "still immersion method" has been adopted, in which enamel blocks or teeth are placed in a beverage and left to stand for immersion for various periods of time before observation. However, the effect generated by the concentration change of the beverage in the oral cavity cannot be explained by standing and soaking, and the effect of the beverage on the teeth cannot be reflected by simulating a real environment, so that the authenticity of an experiment is questioned. To further illustrate the demineralization mechanism of the beverage on the tooth enamel, and more truly simulate and contrast the change of the concentration of the beverage in the oral cavity, the inventor designs a flow device and artificial saliva to maximally simulate the change of the concentration of the beverage in the oral cavity with time after eating the beverage and the damage of the frequency of eating the beverage on the tooth enamel block. Compared with similar experiments, the experiment is equivalent to perfection and supplement, namely, the enamel can be damaged by eating a large amount of beverage for a short time without rinsing, but the enamel can be damaged to different degrees by eating a small amount of beverage intermittently for a long time.

The existing research equipment does not have a flowing device capable of simulating the change of oral cavity concentration and a plurality of groups of equipment for simultaneous comparison. The chinese utility model patent "can imitate beverage in experimental apparatus patent number 201821481455.X that the concentration of oral cavity changes, announced 2019 year 04 month 19 day, disclosed and imitated the device that the concentration of oral cavity beverage changes through mobile device, but adopt above-mentioned device to use very inconvenience when carrying out the contrast experiment, need a plurality of independent devices to experiment simultaneously, required place is great, and is very inconvenient to observing the record moreover.
