Japanese plaqueSome of the tablets in Japan were inscribed by China calligraphers. In Japan, there were some important signboards in places such as the Hokuji Temple and the Kyoto Zen Temple, including some works of China calligraphers. These tablets were passed down from China to Japan, and the most famous of them was Zhang Jizhi's calligraphy. Zhang Jizhi was an important figure in the history of China calligraphy. He successfully built a bridge between Song and Yuan Dynasties. At present, there were only a limited number of Zhang Jizhi's authentic calligraphy works in the world, but there were more than a dozen in Japan. At an auction, a small volume of Zhang Yizhi's calligraphy was sold for more than 60 million yuan, showing the high value of his calligraphy. In addition, the plaque on the signboard of Japanese shrines usually wrote the words "Inawa Shrine". Japanese signboard design focused on neatness, simplicity, and composition, making the signboard more beautiful and artistic.
Why is the plaque repeating?The main reasons for the repeated appearance of dental plaque were as follows:
1. The oral environment: The oral cavity is an environment full of various microorganisms. There are hundreds of thousands of bacteria, which cannot be a sterile environment. This makes it easy for plaque to multiply repeatedly.
2. Inappropriate brushing method: If the brushing method is not effective in removing plaque, it will cause it to appear repeatedly. For example, not brushing your teeth according to the correct brushing method (such as the Bath brushing method), or not brushing your teeth at a 45-degree angle with your gums, repeatedly brushing with high frequency and light force, or not controlling the movement range within an appropriate range.
3. Incomplete cleaning: When brushing teeth, you may not thoroughly clean all sides of the teeth, including the root of the teeth, under the gums, and other places where plaque is easily attached. Moreover, it was difficult to completely remove plaque by brushing teeth. If the soft dirt and food residue between the teeth were not cleaned up in time, it would also provide conditions for the growth of plaque.
4. Mouth physiological characteristics: During sleep, the amount of saliva secretion is reduced, and the ability of the oral cavity to regulate is weakened, creating a good environment for the activity of oral bacteria, which is conducive to the growth of dental plaque; After eating, the sugar in the food will be converted into acidic substances. If the teeth are not cleaned in time, it will also promote the growth of dental plaque.
5. Dieting habits: Eating sweets and acidic foods often will provide a decomposing base for the bacteria in the plaque, thereby promoting their growth and reproduction, causing the plaque to appear repeatedly.
