乳牙不保養 恆齒長不好 Deciduous non-permanent teeth long maintained good

乳牙不保養 恆齒長不好 護牙從小做起 孩子肌肉未成熟時 最好由父母代為潔牙 ●「乳牙自己會掉，所以不需保養，等長出新牙再開始照顧。」這是很多新手媽咪的認知，兒童牙醫師每提到這個就會大搖其頭。 缺乳牙導引 恆齒易長歪 台北市主人翁兒童牙科診所醫師段茂玲表示，幼童上頜骨中，藏有持續分化中的恆牙牙胚，成熟的牙胚在冒出牙齦、取代乳牙時，和乳牙間會以化學物質交換生長方向等訊息，因此若不好好照顧乳牙，讓乳牙提早掉落，視掉落位置不同，未來屬於恆齒的空間多少都會受到侵占，而恆齒沒有乳牙的導引，也容易長歪、長斜。 嬰兒喝奶後 紗布清口腔 乳牙要怎麼照顧？段茂玲指出，新生兒剛出生時，口腔處在無菌狀態，隨著日後飲食種類的增加，慢慢會有菌叢進駐。因此媽媽餵完奶後，一定要用以滾水消毒過的紗布或紗布巾，沾水輕柔的幫小嬰兒清潔口腔，否則口腔內殘餘的奶水，還是會發酵、滋生細菌，而這也將造成嬰兒成長後，口中細菌數量比一般人多。 長第1顆牙 就該用牙刷 從嬰兒長出第1顆牙齒開始，就應該以牙刷清理牙齒，還沒長出牙齒的部份，仍需用紗布巾沾水清潔。 值得注意的是，只要嬰兒長出第2顆牙，且與鄰近牙齒相鄰、有鄰接面的時候，就應該使用牙線，因為牙刷刷毛難以清潔到的牙齒鄰接面，容易有牙菌斑堆積，所以一定要利用牙線將齒縫間的髒東西先行清除。 可拿筆寫字 刷牙的指標 那麼，小朋友何時可以開始自己刷牙？ 段茂玲指出，可自行拿筆寫字是重要的觀察指標，幼童能拿筆寫字，表示小肌肉運作趨於成熟，這時可以試著讓他自行操作正確貝氏刷牙法；在此之前，讓小朋友拿牙刷刷牙，充其量只是讓孩子養成刷牙的習慣，不能冀望孩子自己能將牙齒刷乾淨。 過早學刷牙 當心反效果 過去曾有研究顯示，假設徹底清潔的牙齒是100分，過早教孩子貝氏刷牙法，讓孩子在小肌肉未臻靈活時勉強執行，清潔度僅達10分，反而孩子順著自己的意思，使用「亂七八糟」刷牙法，清潔度則有40分。 由此可見，在孩子肌肉運作未發展成熟時，最好由父母代為執行潔牙的工作。 補充氟化物牙齒更耐酸 在亞洲，除了中國以外，台灣、日本、韓國、新加坡和香港，在自來水中添加氟化物都已行之有年。 段茂玲表示，人體雖可自日常飲食中攝取到氟，卻難足量攝取，對發育中的幼兒牙齒生長會有影響，所以，幼兒發育中的恆牙牙胚若有外加的氟化物參與恆牙鈣化，未來生長出來的恆牙會更耐酸。一般來說，恆牙的發育時間是從0歲開始到10歲，可以每日服用低劑量的氟錠來補充氟化物。 而已生成的牙齒，因為已不再分化，建議可以改用塗氟的方式，將氟化物敷在牙齒表面，可在酸性物質侵蝕牙齒表面時，由氟化物先行出面抵擋，減少牙齒遭蛀蝕機會。 （洪家愉） 2008-09-21 Deciduous non-permanent teeth long maintained good Dental care from a young age children start with immature muscle when the best of parental teeth ● "will be their primary teeth out, so no maintenance, and so grow new teeth start to take care of." This is a lot of new awareness of the Mummy, dentist every child will be referred to the major shake his head. Lack deciduous easy guide permanent teeth long distortion Taipei masters of children's dental clinic physicians paragraph Mao-ling said that the maxillary young children, possession of the continuing division of the permanent tooth germ and mature in the tooth gum up to replace the deciduous teeth, and between deciduous will be the exchange of chemical substances Growth direction of the message, and so on, so do not take good care of primary teeth, so that deciduous early fall, depending on the location of falling, the future belongs to the number of permanent teeth of the space will be occupied, and no permanent teeth of the deciduous guide can also be easily distorted long, long Oblique. Baby milk after oral clearance gauze How to take care of primary teeth? Mao-ling pointed out that paragraph, just newborn at birth, at the mouth sterile, with the future increase in the types of food, slowly flora will be stationed. Wei Wan after the mother milk, therefore, we must employ in order to disinfect water over the gauze bandage or towel, Zhanshui gently clean the baby's mouth to help small, oral or remaining in the milk, or fermentation, the breeding ground for bacteria, and this will also cause infant Growth, the population of bacteria than the average number of people. Long section on the teeth with a toothbrush From the first to grow a baby teeth start, it should clean teeth with a toothbrush, yet most of the teeth grow, the need to Zhanshui clean linen yarn. It is worth noting that as long as the babies grow teeth No. 2, and with neighboring adjacent teeth, adjacent to the surface, they should use floss, difficult to clean because toothbrush bristles into the tooth surface adjacent to, and likely to have plaque accumulation Therefore, we must use to floss between Chifeng dirty things clear first. Brush pen can write indicators Then, when the children can start their own brush? Mao-ling pointed out that the paragraph could be a pen to write on their own observation is an important indicator of a pen to write children, said that the operation of the small muscles mature, then let him try to operate in the right brush Bayesian method; here Let the children take brush toothbrush at best to let children develop the habit of brushing their teeth, their children can not hope to be able to brush teeth clean. Beware of brush are forced to learn counter-productive In the past, studies have shown that the assumption that a thorough cleaning of the teeth is 100 points Early off the children brush their teeth Bayesian method, so that small children might not be flexible when the muscle to force, cleanliness only for 10 minutes, but their children along Meaning, "a mess" brush method, the cleanliness and 40 minutes. This shows that children in the operation of the muscle is not developed, it is best carried out by the parents teeth. To add more teeth fluoride acid In Asia, apart from China, Taiwan, Japan, South Korea, Singapore and Hong Kong, the addition of fluoride in tap water have been for years. Mao Ling Duan said that although the human body can be from day-to-day diet to fluoride intake, and intake hard enough, the development of early childhood tooth growth will be affected, so early childhood development in the permanent tooth germ plus if the participation of fluoride Heng Calcified teeth, the permanent teeth grow in the future will be more acid-resistant. In general, the development of permanent teeth is from 0 to 10-year-old start-year-old, you can take a daily low dose of fluoride to add fluoride tablet. It generated teeth, because the divide is no longer recommended to use fluoride can be a way to enough fluoride in the tooth surface, in acid erosion of teeth on the surface, the first came against fluoride to reduce tooth decay by the opportunity.
