With the development of social economy all over the world, the importance of dental health has risen to an important position. According to this research report, although both China and Thailand are developing countries at present, more than 90% of high school students in China and Thailand believe that dental health is very important to human health. Its cognitive ratio is similar to that of American high school students. In addition, high school students in China and Thailand are no different from American high school students in daily brushing behavior, brushing times and toothpaste selection (choosing high quality), and toothbrushes are changed more frequently, so the ratio of gum bleeding and toothache among high school students is not higher than that of American high school students. It can be seen that the oral health awareness of senior high school students in China and Thailand has been significantly improved and is being put into action.
Undeniably, compared with the United States, there is still a certain gap between China and Thailand in oral health behavior and prevention. For example, although the price of dental floss in other countries is similar and not expensive (10-50 yuan), the use rate of dental floss in American high school students is significantly higher than that in China and Thailand, which shows that high school students in China and Thailand do not know enough about the role of dental floss in dental care. The toothbrush can only brush 70% of the teeth, and the toothbrush at the joint of two teeth can't be cleaned. The perennial accumulation of dirt is an important cause of halitosis and dental diseases. Floss easily enters between teeth, bringing out impaction and dirt, which is an effective method to remove dental plaque, soft dirt and food residue between teeth. The cleaning effect of dental floss on the adjacent surfaces of teeth is better than that of toothbrush or toothpick, oral hygiene will be significantly improved, and the pain caused by dental plugs and diseases caused by dirt will be greatly reduced. If dental floss is used correctly, it can not only keep the adjacent surfaces of teeth clean, but also effectively remove some food embedded in the adjacent surfaces without damaging the gums. If you brush your teeth together, you can keep your mouth clean and healthy. In addition, although the cost of orthodontics in China and Thailand is significantly lower than that in the United States, the number of orthodontists is also significantly lower than that in the United States. Orthodontics, especially children's orthodontics, can not only correct pronunciation, increase patients' self-confidence, but also prevent diseases, because there are many dead corners between teeth, and daily oral cleaning is not easy to clean, which will lead to the growth of bacteria and induce some oral diseases. After orthodontic treatment, this problem will disappear and oral health can be maintained. In addition, uneven teeth often lead to food can not be fully chewed, which will bring greater burden to people's stomach and easily lead to some gastrointestinal diseases. Therefore, high school students in China and Thailand should pay more attention to the effects of dental floss and orthodontics on oral health.
