Children’s dental development has always been a concern for parents, so as a parent, do you know what fossa sealing is all about? Today we will share with you the knowledge related to fissure sealing, so that you will not blame yourself for your child’s mouth full of rotten teeth when he grows up. 1, what is fissure sealing? Fissure closure, also known as point gap fissure closure, refers to the occlusal surface without damage to the tooth tissue, coated with a layer of adhesive resin, when it penetrates the fissure after curing and hardening, forming a layer of protective barrier, covering the fissure, to protect the enamel from bacterial and metabolic products erosion, and enhance the tooth’s resistance to caries, in order to achieve the prevention of fissure caries, a method. The occlusal surface of each person’s grinding teeth is uneven, and the concave part is called the fossa. When the development is not good, these fossas are very deep, and it is easy to embed food and bacteria, and caries will occur easily, which is the fossa caries. 2.The best time for fissure closure The best time for fissure closure is when the teeth are fully erupted and reach the occlusal plane. Generally speaking, the ideal fossa sealing should be done three times, that is, at the age of 3-4 years old for the milk molar once, at the age of 6-7 years old for the “six age teeth” once, at the age of 12 years old for the bicuspid and the second permanent molar once. 3.What is “six-year-old teeth”? When the baby is around 6 years old, the mother can observe the teeth erupting at the end of the baby’s dentition, i.e. behind the second molar, which is the first permanent molar. The first permanent molar in the embryo 3-4 months or so the tooth germ began to form, the birth of the beginning of calcification, 2-3 years of age around the completion of the calcification of the crown, 6-7 years of age when the eruption out of the oral cavity, up and down the right and left each one a total of 4, because of its eruption of babies at the age of 6 years old or so, so customarily referred to as the “six years of age teeth”. In China, more than 90% of the caries in adolescents occur in the fossa area. The “six-year-old teeth” is a good place for fossa caries, it is the earliest eruption time of permanent molar, its chewing function is the most powerful, but also the most prone to caries, and even premature loss, therefore, the protection of children’s first permanent molar teeth is very important. 4, the method of fossa closure The method of fossa closure is very simple, by cleaning the teeth, acid etching, rinsing and drying, applying sealant and curing several steps to complete. When the material is cured and closely bonded to the wall of the groove, it will have a certain resistance to chewing, so that there is no obstacle for the baby to eat. Moreover, the material is non-toxic after curing and will not cause harm to the human body. The mark of success of fissure sealing is that the sealant can exist intact, can be worn but can not fall off. 5, the fossa closed after the precautions (1) just after the fossa closed a few days, such as found closed teeth have overbite, discomfort, pain when eating, should be timely consultation; if found to have part or all of the filling material off, should also be timely re-closed fossa, otherwise it can not achieve the effect of caries prevention. (2) If the fissure sealant is not close or falls off, the sealing fails, and the exposed fissure may become carious again. Therefore, the fissure should be reviewed 6 months after closure, and once a year thereafter, and if it falls off, it should be closed again. (3) Fissure sealing can well reduce the chance of caries on the occlusal surface, but there is no obvious preventive effect on the neighboring surface of caries, therefore, the fissure sealing is not a foolproof insurance for the teeth, still need to brush the teeth carefully, and can not ignore this most basic anti-caries measures. Children’s dental care knowledge 1, pay attention to dental hygiene Generally in the baby 2 years old when the baby began to teach the baby rinse after meals, morning and evening brushing. Let them develop a good oral health habits. When the age of 3 years old, and then gradually teach the baby “upper teeth to the lower brush, lower teeth to the upper brush, inside and outside are brushed to the teeth biting surface do not forget” brushing method. 2.Regular checkups As parents, we should pay more attention to the two or three years after the baby’s teeth eruption, we should try to do a checkup once every six months, and fill in the caries holes immediately, don’t let the caries holes expand, so as to achieve timely prevention, timely detection and timely treatment. 3.Timely repair of caries If you find that the baby has serious caries, the pulp has necrosis, do not easily make the decision to pull out, if you can ask the doctor to do root canal treatment to retain the tooth, dental damage is serious can be used to repair the metal sleeve crown. If you really can’t keep it, you should do the gap keeper according to the specific situation and other corresponding treatment. 4, for “six-year-old teeth” wear “protective clothing” due to “six-year-old teeth” eruption of the earliest, the occlusal surface of the fossa fissure more, the degree of mineralization is poor, food is easy to stagnate. If the baby did not develop good oral hygiene habits, and like sweets, snacks, then this tooth is most likely to occur caries. Therefore, “six-year-old teeth” need more care. When not yet caries, do fossa sealing, for its protective clothing.
