饮食养生:多吃什么对牙齿好

儿童应多吃一些豆类、豆制品、蔬菜、鱼、虾等钙质丰富的食物,以供给足够的矿物质和维生素,使牙齿得到正常的发育。

Children should eat more beans, bean products, vegetables, fish, shrimp and other calcium rich food to provide enough minerals and vitamins, so that the teeth can get normal development.

牛奶和乳制品这些食品中含有大量的钙,钙能抑制细菌产酸,并能防止牙齿的钙磷化合物溶解。

Milk and dairy products contain a lot of calcium, which can inhibit bacterial acid production and prevent the dissolution of calcium and phosphorus compounds in teeth.

此外牛奶中所含的免疫球蛋白和酶等能抑制口腔中的细菌生长。

In addition, the immunoglobulin and enzyme contained in milk can inhibit the growth of bacteria in the mouth.

含氟较多的食物有鱼、虾、海带、海蜇,茶和矿泉水中含量也不少,氟能与牙质中的钙磷化合物形成不易溶解的氟磷灰石,从而防止细菌所产生的酸对牙质的侵蚀。

There are fish, shrimp, kelp, jellyfish, tea and mineral water that contain more fluorine. Fluorine can form insoluble fluorapatite with calcium and phosphorus compounds in dentin, so as to prevent the acid produced by bacteria from eroding dentin.

应少食用加工过细的精制食品(如话梅、巧克力、汽水、糖果、糕点、饼干等)。

Should eat less processed refined food (such as plum, chocolate, soda, candy, cakes, biscuits, etc.).

此外,水果中的果胶还有抑制细菌的作用。

In addition, pectin in fruits can inhibit bacteria.

蔬菜含有许多微量元素和大量的维生素c,也是很重要的抗龋营养素。

Vegetables contain a lot of trace elements and a lot of vitamin C, and they are also very important anti caries nutrients.

而蔬菜纤维通过对牙面的机械性摩擦清洗和刺激唾液腺分泌,可以减少食物的粘附和牙菌斑的形成。

Vegetable fiber can reduce the adhesion of food and the formation of dental plaque by mechanical friction cleaning and stimulating salivary gland secretion.

另外植物油能在牙齿表面形成疏水层,可以保护牙齿,防止牙质溶解。

In addition, vegetable oil can form a hydrophobic layer on the surface of teeth, which can protect teeth and prevent dissolution of dentin.

其实鲨鱼的牙齿就是特化的楯鳞。

In fact, shark teeth are specialized scales.

楯鳞和牙齿是同源器官,有相同的结构:同样有釉质和齿质,里面还有髓腔。

The scales and teeth are homologous organs with the same structure: enamel and dentin, and medullary cavity.

髓腔内同样有神经和血管通入。

There were also nerves and blood vessels in the medullary cavity.

哺乳动物与其爬行类祖先的重要分水岭不是胎生,也不是分泌乳汁,而是牙齿的分化,以及二出齿的出现,所谓二出齿就是动物的一生只有两套牙齿,即我们通常所说的乳牙和恒牙。

The important watershed between mammals and their reptile ancestors is not viviparity or lactation, but the differentiation of teeth and the emergence of two teeth. The so-called two teeth means that there are only two sets of teeth in an animal's life, that is, deciduous teeth and permanent teeth.

哺乳类的牙齿分化为切齿,犬齿,前臼齿,臼齿。

Mammalian teeth are divided into incisors, canines, premolars and molars.

由于牙齿的分化,在咀嚼时必须使上下牙齿的咀嚼面完美的闭合在一起,如果动物一生不断换牙,就有可能打破这种闭合,使咀嚼功能受到影响。

Because of the differentiation of teeth, the chewing surfaces of upper and lower teeth must be perfectly closed together during chewing. If animals change their teeth all their lives, it is possible to break the closure and affect the chewing function.

牙齿的生长牙齿生长与骨骼有一定关系,但因胚胎来源不完全相同,牙齿与骨骼的生长不完全平行。

The growth of teeth has a certain relationship with bone, but the growth of teeth and bone is not completely parallel due to the different sources of embryos.

出生时乳牙已骨化,乳牙牙孢隐藏在颌骨中,被牙龈覆盖;恒牙的骨化从新生儿期开始,18~24个月时第三恒臼齿已骨化。

The primary teeth were ossified at birth, and the spores of the primary teeth were hidden in the jaw and covered by the gums; the ossification of the permanent teeth began in the neonatal period, and the third permanent molar was ossified at 18-24 months.

乳牙萌出顺序一般为下颌先于上颌、自前向后,约于2.5岁时乳牙出齐。

The eruption order of deciduous teeth is that the mandible is prior to the maxilla, from front to back, and the deciduous teeth are fully erupted at about 2.5 years old.

6岁左右萌出第一颗恒牙(第一恒磨牙,在第二乳磨牙之后,又称6龄齿);6~12岁阶段乳牙逐个被同位恒牙替换,其中第1、2前磨牙代替第1、2乳磨牙,此期为混合牙列期;12岁萌出第二恒磨牙;约在18岁以后萌出第三恒磨牙(智齿),也有终生第三恒磨牙不萌出者。

The first permanent tooth (first permanent molars, after the second deciduous molars, also known as 6-year-old teeth) erupts around the age of 6; the deciduous teeth are replaced by the same permanent teeth one by one at the age of 6-12, in which the first and second premolars replace the first and second deciduous molars, which is the mixed dentition stage; the second permanent molars erupt at the age of 12; the third permanent molars (wisdom teeth) erupt after the age of 18, and there are also those who do not erupt the third permanent molars all their lives.

牙齿的健康生长与蛋白质、钙、磷、氟、维生素a、c、d等营养素和甲状腺激素有关。

The healthy growth of teeth is related to protein, calcium, phosphorus, fluorine, vitamin A, C, D and thyroid hormone.

食物的咀嚼有利于牙齿生长。

Chewing food is good for tooth growth.
