September 20th was the 28th National Day for Dental Accident. Yesterday, Nanjing Stomatological Hospital held a large-scale free clinic to publicize dental disease prevention and control knowledge. During the interview, the reporter learned that because the feeding is too elaborate, one of the 10 children now has a "double row of teeth." There are two teeth, one deciduous tooth and one permanent tooth in one's life. After 8 months, the baby begins to grow long teeth, which is generally enough for 20 teeth. After 6 years old, the teeth are replaced by permanent teeth and they are replaced after about 12 years old. If you can protect your child's teeth at these key nodes, he or she will benefit for life. New issues The teeth were not replaced, and 10% of the children grew "double row teeth." Fang Fang (a pseudonym) is 6 years old this year and has just entered the changing period. A few days ago, the family suddenly discovered that the baby's teeth at the lower left incisor had not yet fallen. A new small tooth appeared on the inside, and the new tooth grew slowly. The family rushed to the hospital to diagnose the deciduous teeth and had to remove the deciduous teeth to make room for new tooth growth. "Now, children's long double-row teeth are more and more common, and the clinical rate is as high as 10%, that is, one of the 10 children has a phenomenon of double row teeth, had to come to the hospital to remove the teeth, for the new tooth free Growth space.†According to Ge Jiuyu, chief physician of the Department of Endodontics, Nanjing Stomatological Hospital, under normal circumstances, children from the age of six or seven years old, the deciduous teeth will naturally fall off, and the permanent teeth will erupt in succession between six months and one year. If you eat too much, can not play the physiological stimulation of the teeth, it is easy to form a "double-layered teeth" - when the deciduous teeth can not fall off, and the new eruption of permanent teeth is forced to grow inside. This is the retention of deciduous teeth. If the retention of deciduous teeth is very serious and delayed, affecting eruption and dislocation of permanent teeth may affect the child's occlusion and normal facial development. Feeding too fine is considered the main reason According to Director Ge, the reason why the modern diet is too delicate is an important reason for children's long double teeth. Some parents feel that their children are reluctant to pick up apples and cut them into slices to allow them to use toothpick forks. Previously, children smashed corn. Now, these grains are almost away from the table, and children’s chewing ability is not obtained. Exercise, the teeth can not get enough stimulation, resulting in Lai in the gums do not want to fall off. The new tooth will take time to grow. The baby teeth have not yet fallen. The new tooth will start to go out. The new tooth will have no place. It will only erupt on the side of the teeth. Director Ge suggested that parents should allow their children to eat more chewy foods such as peanuts, sugar cane, apples, and corn to maintain a good stimulatory effect on deciduous teeth and promote timely shedding of deciduous teeth. In addition, once the child has found the phenomenon of double row teeth, it is necessary to go to the hospital in time to pull out the deciduous teeth, to make the permanent teeth grow. New research 90% of dental caries caused by sulcus While the incidence of double-row teeth has been rising, the incidence of dental caries is still high. At present, the incidence of deciduous dental caries in 5-year-olds is as high as 70%, that is, there are 7 teeth in 10 teeth. Dr. Gong Ling, Director of Preventive Stomatology at the Nanjing Stomatological Hospital, said with concern that the deciduous teeth were broken and that new teeth could be grown, but the six-year-old teeth did not have “replacement members†and only had one lifetime. These 4 teeth are easily overlooked due to the eruption of their deciduous teeth. The current morbidity rate is as high as 30%. "Clinical studies have found that 93% of rickets are caused by fissures," she explained. If you look closely, you will find that there are many crevices on the surface of the molars, pits, and pits. These depressions are called pits and fissures. This is caused by obstacles in the process of development and fusion of the cusps of the teeth and is a weak part of the hard tissues of the teeth. For the newly erupted tooth, the pit and fissure area is deep and narrow, and the bristles can't enter and clean, leaving the food residue and bacteria hiding. The bacteria causing bacteria use food to ferment and produce acid and erode teeth to form cavities. 90% Children's dental caries occur here, and we call them pit and fissures. At the same time, the bottom of the pit and fissure is close to the boundary of the glaze dentine or located in the dentine. Once it suffers from convulsions, the destruction can quickly develop to the deep, forming a small, deep and practical cavity that is difficult to detect early. Expert advice Grab three time nodes and put on "protective clothing" for the teeth So, how to prevent these tooth decay? Director Gong suggested that children should be closed as early as possible. The so-called pit and fissure sealing is a method in which the tooth, groove, and point gap prone to rickets are formed on the surface of the teeth without grinding the dental tissue, and is closed with some organic polymer material to keep the teeth free Erosion of bacteria and their metabolites, sequestration of oral deterrence factors, prevention of accumulation of food and plaque, and use of a protective barrier against rickets. The best time for closure is when the crown is completely erupted. When the dental caries have not yet occurred, the common molars are 3-5 years old, the first permanent molars are 6-8 years old, and the second permanent molars are 11-13 years old. Young people with deeper fissures can also use fissure seals to prevent moths. In addition, some of the children's caries occur on the smooth surface and adjacent surfaces of the teeth, and the pit and fissure seal has no preventive effect on the caries. Fluoride is a chemical anti-mite method, which can effectively prevent the smooth surface of teeth and the occurrence of adjacent caries by enhancing the anti-carious ability of teeth and promoting remineralization. Therefore, the combined use of pit and fissure sealing and fluoride can simultaneously prevent pit and gill and smooth facial wart, which can prevent the occurrence of caries as much as possible. Have good teeth, please let your child chew more As society develops, food becomes more and more refined, the jaws used to chew gradually degenerate, become smaller and smaller, and the teeth are still so much, which brings a result that the teeth are arranged more and more crowded and even arranged Nothing causes the deformity of the teeth. Nowadays, children are often taken care of in every possible way. Eating food on weekdays is also a matter of shredding and cooking to make them easy to bite. As everyone knows, this “caress†to reduce children’s chewing movements is consistent with their use. The disuse theory is extremely unfavorable to the growth and development of children's maxillofacial regions. Chewing exercise has the following aspects: 1. Children and adolescents can promote the development of maxillofacial bones and muscles by properly chewing hard foods, so that they can be coordinated with erupted permanent teeth, which is conducive to tidy teeth. 2, chewing exercise can stimulate the secretion of saliva, strengthen the lips, cheeks, tongue, the scrubbing of the teeth and saliva on the tooth surface cleaning effect. 3, chewing campaign in the food chew, so that the saliva evenly mixed into the food, so that you can not only taste the delicious food, but also conducive to the digestion and absorption of food, enhance children's appetite. - Extended reading These actions will make your teeth more and more ugly Dr. Jiang Yong, the fifth outpatient department of Nanjing Stomatological Hospital, told the reporter that the incidence of malocclusion of the teeth is about 60%. There are hereditary factors, and there are acquired factors, such as habitual tongue sticking, licking, biting up and down lips, Biting things, breathing with the lips, unilateral chewing and sleeping, etc. These seemingly inconspicuous habits can cause malocclusion in the teeth and can cause deformities in the teeth over time. General deformities include tooth deformities and skeletal deformities. Teeth deformities can be corrected by wearing braces. 11-13 years old is the best time to wear braces, girls develop early, treatment time should be properly advanced to 10-12 years old. The treatment of skeletal deformities is more complicated. If it is covered in the sky, it is recommended that it be corrected from 3.5 to 5 years old. Some serious skeletal deformities need to be treated with surgery after 18 years of age.
