Toothbrushes are indispensable in our daily lives. Small toothbrushes are inconspicuous, but they are closely related to our oral hygiene and health. Would you buy a Toothbrush? Will you use the toothbrush correctly? The "Weekly Quality Lecture Hall" co-sponsored by the Yangtze Evening News and the Jiangsu Provincial Quality Supervision Bureau, invited the director of Yangzhou Quality Inspection Institute Shi Jiangyang in this issue, and asked her to introduce us to introduce the common sense of toothbrush purchase.
Unqualified focus on sanding project
Every year, the quality supervision department of our province will conduct a spot check on the quality of the toothbrush. From the previous spot check, the items with unqualified toothbrush quality are mainly concentrated on the sanding project, that is, the pass rate of the top end of the monofilament does not meet the standard requirements. Shi Jiangyang said in an interview that since the toothbrush directly contacts the oral cavity, while cleaning the oral cavity, it is also necessary to minimize the irritation to the oral cavity and the comfort of the user. Therefore, in general, the toothbrush must undergo a grinding process in the production process, that is, It is required that the tip contour of the monofilament must be removed at an acute angle to achieve a state without burrs and no sharp angles.
The Yangzi Evening News reporter learned that although the sanding process is very important in the production process of toothbrushes, because consumers are difficult to distinguish with the naked eye when purchasing, some toothbrush manufacturers intentionally omit this link to save costs, and cause The project failed. The use of a toothbrush that does not pass the sanding is not only unable to achieve the effect of cleaning the teeth, but also damages the gums and the mouth.
There are no advantages and disadvantages in the soft and hard bristles.
At present, the toothbrush bristles sold in the market are mainly divided into three types: soft hair, medium hair and hard hair. Since the price of a soft toothbrush is generally higher than that of a hard tooth toothbrush, many consumers think that the quality of a soft toothbrush is better than that of a hard toothbrush. Hairbrush. Shi Jiangyang said that in fact, this is a misunderstanding of consumption. Whether it is soft hair, hard hair or medium hair, the hardness of the bristles is actually not good or bad. Consumers can choose the right toothbrush according to their own situation and preferences. Different consumers have different requirements on the hardness of the toothbrush bristles, and it is generally suitable to use a medium-toothed toothbrush. Special people, such as children or patients with periodontal disease and tooth allergy, may choose a soft-bristled toothbrush or a sharp-edged toothbrush.
Three new standards will be implemented next year
The mandatory national standards for the three toothbrush series of Toothbrush, Children'S Toothbrush and Sharpened Toothbrush have been released recently and will be officially implemented on December 1, 2014. Three mandatory national standards for toothbrushes also appear to be advancing with the times. For example, the 2003 version of the toothbrush standard contains only five heavy metal elements of arsenic, cadmium, chromium, lead and mercury, and the new standard adds 锑 and 钡. Specification requirements for three heavy metal elements of selenium. With the continuous improvement of the toothbrush production process and the use of more and more new materials, new toothbrush varieties such as sharp-tip toothbrushes and silicone toothbrushes cannot be adapted to the existing toothbrush standards. Filling the gap in the national standard of the product will also make the production of the product more standardized.
Because children's oral mucosa and teeth are relatively fragile, among the three new toothbrush standards, Children's Toothbrush has the strictest standards, and specifications, hair bundle strength, hygiene, safety, and accessories and plug-ins are detailed. For example, the strength of sanding must meet the requirements of soft hair. In order to attract children, many manufacturers add some ornaments or parts to the toothbrush handle as a selling point. The standard also makes these detachable and non-detachable parts. Detailed rules were issued.
Electric Toothbrush is not for everyone
Nowadays, electric toothbrushes are more and more popular among consumers. The Yangzi Evening News reporter learned that the correct use of electric toothbrush does have the effect of removing plaque, preventing caries and periodontitis, but ordinary toothbrush can also achieve these effects. However, many people brush their teeth manually, due to improper methods, brushing force is too large, easy to cause unnecessary damage to teeth and gums, and electric toothbrush can reduce this damage, massage the gums. However, it is worth mentioning that if the electric toothbrush is not handled properly, it will also cause damage to the teeth. The dentist recommends that the brush should be brushed up and down, that is, the vertical brush, while the electric toothbrush vibration frequency and force are relatively fixed. When rotating, the tooth surface is similar to the horizontal brush, which may cause certain wear on the teeth, and may also cause periodontal Inflammation and so on. If the teeth themselves are not very good, such as gingivitis and periodontitis, it is best not to choose an electric toothbrush.
Don't forget to change your toothbrush regularly
When we buy a toothbrush or Toothpaste, we often see the “I recommend a toothbrush every three months” message on the outer packaging. This is really important in daily life. After the toothbrush has been used for a period of time, curling, breakage, etc. will occur, and the cleaning ability of the toothbrush will be deteriorated. It is better to replace the new toothbrush. The period of replacement every three months is mainly based on the damage of most people's toothbrushes. Consumers can shorten the replacement time according to their own use. Under special circumstances, if the disease is cured, it will be replaced immediately. For example, if the mouth has inflammation and the body immunity is low, the replacement period will be shortened.
In addition, it should be reminded that as long as the toothbrush is used for a period of time, a large amount of bacteria will grow and multiply. Therefore, after using the toothbrush, wash it thoroughly, and put the toothbrush head up in the mouth cup, or put it in the air. Sunlight places to achieve the purpose of drying and sterilization.
