孩子多吃堅硬食品 防牙齒畸形Children eat more solid food anti-teeth deformity

孩子多吃堅硬食品 防牙齒畸形 【新華網】近年來，兒童牙齒錯合畸形的發病率越來越高，其中一個重要原因是：兒童食品越來越精細，孩子的咀嚼功能弱化。專家建議家長多給孩子吃牛肉乾、燒餅等「堅硬耐磨」的食品，有助孩子的牙齒整齊健康。 據深圳市第二人民醫院口腔科主任梁芮表示，牙齒錯合畸形的原因主要是遺傳因素和環境因素。在環境因素中，後天因素起著很大的作用，其中咀嚼功能退化是主要原因之一。現在的兒童食品越來越精細，大量奶製品、麵包、膨化食品，使孩子的咀嚼功能越來越弱，牙齒和口腔內外的肌肉得不到應有的鍛鍊，導致肌肉無力、萎縮，頜骨發育異常，但牙齒的數量並沒有減少，所以兒童牙齒錯合畸形的發病率也越來越高。 梁芮說，精細的食物還容易引起牙齒齲壞，出現牙齒缺損、乳牙過早丟失、恒牙萌出間隙不足，進而造成牙齒排列不齊。 梁芮提醒家長，在替牙期內補鈣對於牙齒及頜骨生長的作用遠低於咀嚼功能訓練。應加強兒童咀嚼功能訓練，充分鍛鍊口腔肌肉功能，進而有效刺激下頜骨的生長發育。 要多給孩子吃一些堅硬耐磨的食品，如排骨、牛肉乾、燒餅、鍋巴、饅頭乾、蘋果等。孩子2歲左右乳牙基本完全萌出後，應定期到正規口腔專科檢查，預防齲齒，保證恒牙的正常萌出，同時對有頜骨異常發育的患兒進行早期預防治療。 2008-09-30 Children eat more solid food anti-teeth deformity Xinhua】 【In recent years, the children's teeth wrong jointly malformation of the rising incidence of one of the important reasons are: children, more and more fine food, children's weakening chewing function. Experts recommend parents give their children to eat beef jerky, fried, and other "hard wear" the food, help the child's teeth healthy and tidy. According to the Shenzhen Second People's Hospital, said Rui Liang, director of dentistry, teeth wrong jointly deformed due to genetic factors and environmental factors. Environmental factors, the day after a lot of factors play a role, which is the degradation of the chewing function of one of the main reasons. Now more and more fine food for children, a large number of dairy products, bread, puffed food, so that the child's chewing function more and more weak, both inside and outside of the mouth and teeth are not properly exercise the muscles, resulting in muscle weakness and atrophy, jaw Dysplasia of bone, teeth, but the number has not declined, the children's teeth wrong jointly incidence of deformity was also getting higher and higher. Rui Liang said, fine food is also easily lead to dental caries, dental defects occur, the premature loss of deciduous and permanent teeth eruption lack of space, which resulted in irregular teeth alignment. Parents Xing Rui Ti Liang, for calcium during tooth for tooth and jaw growth much lower than the role of the chewing function of training. Should strengthen the training of children chewing function, the full exercise of oral muscle function, thereby effectively stimulate growth and development of the mandible. To give a child to eat some of the hard wear-resistant food such as pork, beef jerky, sesame seed Guoba, dry bread, apple and so on. 2-year-old children about basic full eruption of primary teeth should be on a regular basis to formal oral examination specialist in the prevention of dental caries, to guarantee the normal eruption of permanent teeth and jaw at the same time there is abnormal development of children with early preventive treatment. 2008-09-30 View more information, see the World Journal reported that e-ePaper

自體移植 牙齒也可種回去Autologous transplantation can be kind of back teeth

自體移植 牙齒也可種回去 【施靜茹】因齒顎矯正拔掉臼齒，或用不到的智齒，過去可能拔掉不用，台北醫學大學日前成立台灣首家保存恆牙的牙齒銀行，標榜以後蛀牙能做為自體牙齒移植。 台北醫學大學牙醫學系主任李勝揚指出，自體牙齒移植和牙齒再植，就是把口內一顆健康牙齒拔起來後，移植到另一顆缺齒位置，在台灣臨床發展十多年，成功率可達九成。 適合做自體牙齒移植的牙齒，包括智齒、齒顎矯正拔掉的臼齒、牙齒萌發位置或角度異常的多生牙、阻生牙，都能保存。 李勝揚說，日本厚生省與齒科醫師19年前就提出「8020」運動，希望日本國民到80歲，仍擁有20顆自己的牙齒，所以這次北醫與日本廣島大學牙齒銀行合作，使用專利程式降溫儀，避免因冰晶形成造成細胞受損。 至於保存恆牙能否萃取幹細胞做為保存？李勝揚說，乳牙能取得牙髓體積約0.2cc，恆牙約0.4cc，再從中分離培養幹細胞保存，待日後幹細胞技術達純熟境界，就能使用。 台北榮民總醫院牙科部主任高壽延說，過去治病人牙齒時，如果病人剛好第一、二大臼齒蛀牙，而且第三大臼齒（智齒）還在，就可以用智齒補臼齒蛀牙。 不過，高壽延強調，第一、二大臼齒如蛀得早，後面牙齒可能向前推，使蛀牙牙槽空間縮小，再加上有人智齒牙根呈爪狀，相對較大，必須修磨才能移植蛀牙區，但可能使牙周細胞受損，造成移植效果變差。 2008-09-30 Autologous transplantation can be kind of back teeth Shi Jing-Ru】 【because of Orthodontists molar pulled, or less than the wisdom teeth, in the past may not have pulled out, Taipei Medical University recently set up to preserve Taiwan's first permanent teeth Bank, tooth decay can do for itself after autologous transplantation teeth . Taipei Medical University dental Head of the Department of Li Yang pointed out that the autologous transplantation of teeth and tooth replantation, the mouth is a healthy tooth pulled up, transplanted to another location of the missing tooth in Taiwan for more than a decade of clinical development, the success rate is Up to 90. Suitable for autologous transplantation teeth teeth, including wisdom teeth, pulled out of Orthodontists the molar teeth or the location of the germination point of view of the abnormal teeth, impacted teeth can be preserved. Li Yang said that the Japanese Ministry of Health and Welfare and dental doctors 19 years ago on "8020" campaign hope that the Japanese people to the 80-year-old, still has 20 of his teeth, so the Taipei Medical University and Hiroshima, Japan Bank teeth, the use of patented cooling program Miriam, to avoid the formation of ice crystals cause damage to cells. As for the preservation of permanent teeth can extract stem cells for preservation? Li Yang said that the deciduous dental pulp can be made about the size 0.2cc, permanent teeth about 0.4cc, and then separated from stem cells to preserve culture, stem cell technology in the future to be reached proficient level, you can use. Taipei Veterans General Hospital Department of Dentistry, said Yan, director of Igor, who in the past dental treatment, if the patient is just the first and second molar tooth decay, and the third molars (wisdom teeth) also can fill with wisdom molar tooth decay . However, the extension of Igor stressed that the first and second molars as early borers, the back teeth may be pushed forward so that the alveolar space to reduce tooth decay, plus some wisdom teeth were root-like claws, relatively large, the mill would have to be transplanted District tooth decay, periodontal cells could cause damage, resulting in the deterioration effect of transplantation. 2008-09-30 View more information, see the World Journal reported that e-ePaper

電動牙刷差別只在快慢The difference of electric toothbrushes is only in the speed

電動牙刷差別只在快慢 【詹建富】電動牙刷問世，刷牙進入電動時代，甚至還有所謂音波電動牙刷，以及內建藍牙裝置的導航電動牙刷，號稱讓刷牙變得輕鬆省事。問題是電動牙刷的潔牙效果會比一般的手動牙刷好嗎？ 台北醫學大學附設醫院牙周病科主任呂炫指出，在門診中，常有病人問起： 「電動牙刷有比較好嗎？ 」他總是拿腳踏車和機車做比喻，如果以目的地來說，兩者都可到達，差別只在快慢而已；同樣的，若採用相同的刷牙手法，電動牙刷和傳統牙刷的清潔效用也都差不多，唯一的差別在於電動牙刷瞬間轉動次數非常快，可大幅降低潔牙時間。 不過，呂炫指出，部分民眾常以為電動牙刷可以自動刷牙，刷牙動作反而不正確，效果反而差。 用電動牙刷刷毛仍應輕輕接觸到牙齒表面，然後輕輕地以圓弧方式擺動震動中的牙刷頭，否則刷不到正確的位置，根本無法有效去除牙菌斑。 另外，目前雖有兒童專用的電動牙刷，握把非常輕巧，但呂炫認為，兒童使用電動牙刷還是有其年齡上的限制，最好是6至8歲以上及單手能有效握住牙刷的握把，家長應確定孩子已習慣一般牙刷，再使用電動牙刷。 2008-09-19 The difference of electric toothbrushes is only in the speed Zhan Jian Fu】 【electric toothbrushes come out, brush their teeth into the electric age, and even the so-called acoustic electric toothbrush, as well as built-in Bluetooth navigation devices for electric toothbrush, so-called brush easily become easier. The problem is the electric toothbrush teeth than the normal effect of the manual toothbrush, please? Taipei Medical University Hospital, director of Periodontology Xuan Lu pointed out that the patient, the patient often asked: "There compare electric toothbrush?" He always take a bicycle and motorcycle to do an analogy, if the destination, Both can be arrived at, the only difference in the speed of it; Similarly, the use of a brush the same way, the electric toothbrush and clean the effectiveness of traditional toothbrushes are almost the only difference is that the electric toothbrush the moment the number of rotating very fast, can significantly Reduce the time to clean teeth. However, Hyun Lui pointed out that some people think that electric toothbrush automatically brush, movements do not brush their teeth correctly, but poor results. Using electric toothbrush bristles should gently touch the surface of the teeth, and then gently arc to swing the way of shock in the first toothbrush, or less than a brush in the right place, can not effectively remove plaque. In addition, although at present the exclusive use of electric toothbrushes for children, is very lightweight grip, but Lu-hyun of the view that the use of electric toothbrushes for children or have restrictions on their age, preferably 6-8 years of age and single hand can effectively hold the toothbrush Grip, the parents should be sure their children have been accustomed to the general toothbrush, and then use the electric toothbrush. 2008-09-19 View more information, see the World Journal reported that e-ePaper

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.

每次吃完 都要潔牙？ After each have teeth?

每次吃完 都要潔牙？ �� Q：小朋友常常在不同卻相近的時間吃東西，等他吃完了再一次清潔，比較省時省力？ A：大錯特錯，這種作法將使幼童牙齒長時間暴露在蛀牙風險中。段茂玲指出，吃東西後，口腔PH值會降低，通常經過20分鐘，口水就會進行口腔自潔，提高PH值，避免牙齒遭蛀蝕，但如果每隔一小段時間就吃一次東西，反覆降低PH值，反而對牙齒傷害更大。 因此她建議，幼童吃東西最好要集中在短時間內一次吃完，不要吃一口玩一會兒，等一下再來吃；且每次吃完後，都要進行清潔，才不會蛀牙。 2008-09-21 After each have teeth? Q: children are often similar but different in time to eat, he again finished a clean, relatively labor-saving time? A: a big mistake, which will enable the teeth of young children for a long time exposure to the risk of tooth decay. Mao-ling pointed out that paragraph, eating, oral PH value will be reduced, usually after 20 minutes, the water will be conducted oral self-cleaning to raise PH value, to avoid tooth decay by, but if every time a small section of the first things to eat, Over and over again to lower PH value, but more damage to the teeth. She therefore suggested that young children eat the best things to focus on eating a short period of time, do not eat a play for a while, then wait to eat; and finish every time, have to be clean, not only tooth decay. 2008-09-21 View more information, see the World Journal reported that e-ePaper

認真刷牙 為何爛牙？Why brush serious tooth decay?

認真刷牙 為何爛牙？ 【本報訊】Q：為什麼有的人明明就很認真刷牙，卻依舊一口爛牙；有的人不好好刷牙，牙齒卻看起來很健康。容不容易蛀牙是不是跟體質有關？ A：認真刷牙的人不見得清潔的方式正確，可能光刷牙沒有用牙線，或者牙刷刷毛都倒了還捨不得更換，因此沒能達到清潔的目的。 而不好好刷牙的人更有可能是因為根本還沒發現牙齒有問題，所以自以為牙齒很健康。 她認為，想擁有一口健康的貝齒絕無僥倖，雖然極少數人的確是因為先天體質，牙齒比較抗酸，不易遭蛀，但不管如何，一定都要把握徹底清潔和定期洗牙兩大原則，才能保有健康牙齒。 2008-09-20 Why brush serious tooth decay?

333黃金刷法 蛀牙拜拜333 gold tooth brushing bye

333黃金刷法 蛀牙拜拜 【詹建富】想要擁有一口潔白的貝齒，除了先天遺傳，最重要的是維持良好的口腔衛生習慣。 台灣林口長庚兒童醫院小兒牙科主任林孝禺提出「333黃金刷牙準則」，亦即每天3餐後都要刷牙、用餐後3分鐘內要刷牙，以及每次刷牙至少要3分鐘，就能確保牙齒清新、健康。 3餐飯後都刷牙 目前最常刷牙的時段往往固定在早上起床後及睡前，林孝禺表示，1天3餐通常是我們比較固定進食的時候，應建立餐後立即潔牙的習慣，才是正確的口腔衛生習慣。做到3餐後都刷牙，是預防蛀牙的第1步。 餐後3分鐘內刷 林孝禺指出，用餐後卡在牙縫中的食物殘渣，經過唾液的混合，就是孳生細菌的溫床，並逐漸累積成覆蓋在牙齒表面的牙菌斑。 另一方面，口腔內原本的酸鹼平衡狀態，也會隨著進食而呈酸性，如果口腔內長時間處於酸性環境，將有利於牙菌斑的生長，進而造成牙齒脫鈣及蛀牙。 因此，建議在餐後的黃金3分鐘內刷牙是最好的，即使不方便刷牙，至少也要用清水漱口或喝白開水，以降低口中酸性值。 刷牙至少3分鐘 根據統計，平均刷牙時間少於2分鐘。現代人工作忙碌，刷牙時也都非常草率。林孝禺表示，若要達到清潔牙齒的目的，其實以貝氏刷牙法，每兩顆牙的牙面都至少要來回刷10次才夠，只是要真的去計算刷牙次數並不容易，因此若以時間估算，大約每次刷牙最少應有3分鐘，才有足夠的時間讓清潔劑停留在口中發揮潔牙效果。 2008-09-18 333 gold tooth brushing bye Zhan Jian Fu】 【want to have a white Beichi, in addition to congenital genetic, the most important thing is to maintain good oral hygiene habits. Taiwan Linkou Chang Gung Children's Hospital pediatric dental Lin Yu, director of the "333 gold brush guidelines", that is 3 a day meal should brush their teeth, eat 3 minutes to brush their teeth, brush their teeth every time, as well as at least 3 Minutes, we can ensure that the teeth clean and healthy. 3 brush their teeth after meals At present, most of the time often brush their teeth fixed in the morning before going to bed and get up later, Lin Yu said that 1 day 3 meals we usually eat relatively fixed, should be established immediately after meal used to clean teeth, is the right of oral hygiene . 3 brush their teeth after dinner to do all that is the prevention of tooth decay in step 1. Brush with 3 minutes after meal Lin Yu pointed out that after the meal card in the dental residues in food, through saliva mixed, that is a breeding ground for breeding bacteria, and gradually accumulate to cover the surface of the teeth in dental plaque. On the other hand, the mouth of the original acid-base balance, but also with the consumption of acidic, mouth for a long time in acidic environment will be conducive to the growth of plaque, which cause tooth decay and tooth decalcification. It is therefore recommended that the gold meal in 3 minutes brushing is the best, even if brushing is not convenient, at least with mouthwash or clean water to drink boiled water to reduce the acidity of the population value. Brush their teeth at least 3 minutes According to statistics, the average time to brush their teeth less than 2 minutes. Modern busy work, brush their teeth when they are very hasty. Lin Yu said, in order to achieve the purpose of cleaning teeth, in fact, Tony's brush with law, Liang Keya each of the tooth surface at least 10 times to brush back and forth enough, but to really have to calculate the number of brush it is not easy, so If time is estimated that about brushing their teeth every time there should be at least 3 minutes, only to allow sufficient time for cleaning agents remain in the mouth to play a scaling effect. 2008-09-18 View more information, see the World Journal reported that e-ePaper

沒有牙膏 也可以刷牙Toothpaste can not brush their teeth

沒有牙膏 也可以刷牙 【詹建富）】在口腔保健中，牙刷和牙膏是必備的用品，也有人以牙粉取代牙膏。但牙醫師指出，如果出門在外，沒有牙膏，只用牙刷也能刷牙，重要的是刷牙的動作，牙膏其實是配角。 刷牙配角 方便毛滑動 台北醫學大學附設醫院副院長鄭信忠指出，市售牙膏的組成成分，不外是起泡劑 （濕潤劑）、打磨劑、芳香劑 （甘味劑）和治療劑。 起泡劑和濕潤劑可降低牙齒表面張力，維持牙膏濕潤度，以便牙刷刷毛的滑動；打磨劑是幫助去除牙齒表面的色素、牙菌斑等物質；芳香劑和甘味劑則提升牙膏的香味及口感；治療劑則是將有治療作用的藥物加入牙膏中，以預防或治療牙齒與口腔疾病，目前以含氟牙膏、去敏感牙膏及含中藥成分的牙膏為主。 特殊牙膏 別長期使用 鄭信忠表示，消費者可根據治療目的來選擇牙膏，例如要防止蛀牙，則選擇含氟牙膏，若要防止牙齒酸軟敏感，則選擇去敏感牙膏。 要注意的是，具特殊功能的牙膏不宜長期使用，使用前應先徵詢牙醫師的意見，而且它也不能代替普通牙膏來用，更不建議兒童使用。 以去敏感牙膏為例，這類牙膏能封閉牙本質小管，阻隔它對冷熱刺激的傳導，進而降低牙齒敏感程度，如果症狀持續，就要找牙醫師找出牙齒痠軟的根源所在。 美白牙膏 用久會傷齒 此外，某些市售美白作用的牙膏，它所含的微粒比較大，藉此磨去牙齒表面的牙漬，獲得漂白的效果，但鄭信忠提醒，如果顆粒過粗，長期使用下，反而會破壞牙齒表面結構，最終讓牙漬更容易附著在牙齒上，消費者切勿為了美白而得到反效果。 至於牙膏的用量多寡，鄭信忠表示，電視上的牙膏廣告常出現在牙刷刷毛上擠出一長條的鏡頭，其實太浪費了，大約擠出黃豆大小即可。 2008-09-20 Toothpaste can not brush their teeth 【Zhan Jian Fu)】 in oral health, toothbrush and toothpaste is essential supplies, was also to replace tooth powder toothpaste. But the dentist said that if away from home, no toothpaste, toothbrush just can brush their teeth, it is important to brush their actions, toothpaste is in fact a supporting role.

It should be noted that a special function in toothpaste is not appropriate for long-term use, before the use of consultation with the dentist's advice, and it can not be used to replace the ordinary toothpaste, but also does not recommend the use of children. In order to sensitive toothpaste, for example, such a small dentinogenesis toothpaste tube can be closed, blocking the conduction of its hot and cold stimulation, and reduce the sensitivity of the teeth, if the symptoms continued, to find a dentist to identify the root causes of tooth limp. Whitening toothpaste will be used for a long time tooth injury In addition, some of the effects of whitening toothpaste on the market, it contains larger particles to the surface of the teeth Moqu teeth stains, was the bleaching effect, but Hsin-Chung Cheng reminded that if the particles have been rough, long-term use, but Would undermine the structure of the tooth surface, so that the final stain teeth more easily attached to the teeth, the whitening and consumers in order not to be counter-productive.

愛吃酸 毀了牙齒琺瑯質 胃酸逆流、碳酸飲料… 造成琺瑯質流失 正確刷牙、勤漱口很重要 　牙齒酸蝕第一級，牙釉質稍流失，外觀變黃無光澤。 　牙齒酸蝕第三級，已侵蝕至牙本質三分之一。 【施靜茹】嗜吃酸性食物或愛喝碳酸飲料的人，要小心牙齒可能遭到酸蝕，造成琺瑯質流失，嚴重時可能牙髓神經露出來，得接受牙醫根管治療，甚至拔掉牙齒。 台灣高雄醫學大學附設中和醫院牙周病科主任何坤炎說，牙齒酸蝕原因，包括牙齒琺瑯質接觸到酸性物質（pH值小於5.5）、年齡增長累積酸性物質、刷牙方法不對、有胃酸逆流的人，都可能導致琺瑯質流失。 何坤炎曾收治一名50多歲的女性病患，由於平常有喝健康醋的習慣，後來覺得牙齒痠痛前往就醫，經過檢查發現，她已是第四級牙齒酸蝕，牙本質暴露超過三分之二，再不及時處理，牙髓神經可能就會露在外面。 不少年輕人愛喝碳酸飲料，有一名女模特兒道聽途說，認為喝有氣泡的碳酸飲料能去除食物殘渣，讓黃板牙變白，她也依樣畫葫蘆，後來也出現酸蝕性牙齒，牙齒形狀差點就變得破碎。 還有一名18歲大學生，平常愛喝可樂，因牙齒不舒服去看牙醫，也發現齒頸部琺瑯質變色且脫鈣，快要成為牙齒酸蝕一族。 何坤炎說，牙齒被酸性食物侵蝕的症狀，患者往往在初期沒感覺，可能偶爾局部痠痛，但琺瑯質會漸漸失去光澤和紋理，最後演變到牙本質和牙髓神經暴露。 何坤炎表示，如果屬於酸蝕的牙齒，牙醫師通常會檢測患者牙齒，顏色是否變黃、牙切緣有變薄呈半透明狀、牙齒結構是否易碎且呈鋸齒狀，甚至牙齒表面有杯狀或窩洞的酸蝕等症狀。 因此，何坤炎建議，偏好吃酸性食物的人，不妨在進食後，再喝幾口白開水漱口，就能沖淡口中的酸性環境；如果喝酸性飲料，也應避免小口長時間啜飲，或儘量不要含在口中過長。 台北榮民總醫院牙科部主任高壽延表示，無論是甜、鹹、酸食物，最重要還是吃完東西應仔細刷牙，因為牙菌斑停留在牙齒一段時間，就會使牙齒產生局部偏酸環境，增加蛀牙的機會。 2008-08-20 Favorite acid to destroy tooth enamel Weisuanniliu, carbonated drinks… caused the loss of enamel, brush their teeth correctly, Qin mouthwash is very important Dental etching the first-class, slightly enamel loss, dull appearance turn yellow. Dental etching the third grade, has been eroded to one-third of dentin. [Shi Jing-Ru:嗜eating acidic food or carbonated drinks Aihe people to be careful teeth may have been etching, resulting in the loss of enamel, may be seriously exposed to nerve pulp, a dental root canal treatment, and even pulled out teeth. Taiwan's Kaohsiung Medical University Hospital and periodontal disease in the attached director Kun-Yen Ho said, teeth etching reasons, including tooth enamel exposed to acid (pH value of less than 5.5), age cumulative growth of acidic substances, brushing method is wrong, there Weisuanniliu People are likely to lead to the loss of enamel. Kun-Yen Ho had treated a 50-year-old female patient, as usual with the habit of drinking vinegar health, dental pain that was later to seek medical treatment, after examination revealed that she had the fourth-class dental etching, exposed more than two-thirds of dentin Second, does not timely processing, pulp nerve may be Louzaiwaimian. Many young people Aihe carbonated drinks, a female models hearsay that the bubble has to drink carbonated drinks to remove food residue, Huang Banya white, she also依样画葫芦, but also etching of teeth , The shape of teeth becomes almost broken. Another 18-year-old university student, usually love He Kele, uncomfortable look at the teeth because of dental, also found that tooth enamel discoloration neck and decalcification, is about to become a dental etching owners. Kun-Yen Ho said that the teeth were the symptoms of acid erosion of food, patients often did not feel at the early stage, localized pain may occasionally, but the enamel will gradually lose their luster and texture, the final evolution of the nerve exposed dentin and pulp. Kun-Yen Ho said that if they are etching the teeth, dentists usually detected in patients with teeth, whether or not to turn yellow color, teeth have thinner margins with a translucent, dental structure is fragile and was Juchi Zhuang, and even tooth surface goblet Cavity or the etching, and other symptoms. Therefore, Kun-Yen Ho suggested that eating acidic food preferences of the people, may wish to eat, Zaihe几口water gargle, the population will be able to dilute the acidity of the environment if they drink acid drinks, should also avoid small I indulge a long time, or try to give In the long-mouth.

玻璃離子體 填乳臼齒防蛀牙

玻璃離子體 填乳臼齒防蛀牙 　兒童乳臼齒凹隙縫平時無法清理，填補上玻璃離子體材料，可以有效減少咬合面蛀牙。 ●台灣5歲以下小朋友，七成五者至少有一顆蛀牙，台北榮民總醫院追蹤發現，小朋友使用玻璃離子體材料封填乳臼齒凹隙，對預防咬合面蛀牙效果不錯。 台北榮總兒童牙科主治醫師施文宇說，現在的家長越來越注重小孩口腔衛生，再加上氟化物使用普遍，「小朋友蛀到滿口爛牙才來就醫比以前少。」 不過，由於乳臼齒咬合面較深的溝隙，容易積存細菌及食物殘渣，刷牙不容易刷乾淨，氟化物對預防咬合面蛀牙效果有限，臼齒凹隙封填就成了預防蛀牙的方法之一。 施文宇指出，一般使用樹脂材料，做臼齒凹隙封填，但對成人恆牙臼齒的效果較好；6歲以下小朋友治療時，較難控制口水，大多會選擇玻璃離子體，台北榮民總醫院兒童牙科再將此材料經技術處理，調得稍為濃稠。 台北榮民總醫院蒐集481顆經玻璃離子體材料封填凹隙的乳臼齒，發現不管追蹤半年、一年或兩年，玻璃離子體留置率超過八成，即使脫落，玻璃離子體中的氟化物仍會滲入乳臼齒凹隙，乳臼齒頂多只會有淺淺的窩洞或稍微變色。 施文宇說，玻璃離子體優點為可直接黏在牙齒上，不必先在牙齒咬合面鑽洞，施作過程也不怕口水汙染，且封填後會持續釋放氟化物，對抗細菌，雖然持久性不如樹脂，但小朋友會由乳牙換成恆牙，沒有時間的疑慮。 施文宇表示，世界衛生組織建議，5歲以下小朋友至少蛀一顆牙比率，不應超過五成者，小朋友三歲以後乳牙長齊約20顆，或可考慮做乳臼齒凹隙封填。（施靜茹） 小朋友如何預防蛀牙 吃完東西就刷牙 刷牙時使用牙線 減少吃甜食的數量和頻率 使用氟化物預防蛀牙，如含氟牙膏、含氟漱口水、氟膠、氟漆、氟錠 做凹隙封填預防蛀牙 定期口腔檢查 （資料來源／台北榮民總醫院牙科部） 2008-02-03

記憶可能被拔走

記憶可能被拔走 研究發現，牙齒健全者的記憶力明顯比牙齒被拔除的人要好得多。 　拔牙會使部份記憶消失，對於老人牙齒狀況和失憶症的研究來說可能是突破性的進展。 【新華網】瑞典科學家最新公布的一項研究報告顯示，當疼痛的牙被拔掉時，人的部分記憶也被「拔」掉了。 據中國中醫藥報報導，為了進行這項研究，從1988年開始，瑞典余默奧大學研究人員在長達15年的時間裏對1962名年齡在35歲至90歲的志願者進行了跟蹤調查，對牙齒健全志願者的記憶力和牙齒被全部拔除、使用假牙的志願者的記憶力進行了比較。 科學家發現，在所有如教育、年齡、疾病史等其他因素全部相似的情況下，牙齒健全者的記憶力明顯比牙齒被拔除的人要好得多。 余摩奧大學副教授揚．貝里達爾說：「我們自己對這個結果也感到很驚訝。對於老年人牙齒狀況和失憶症的研究來說，這都可能是個突破性的進展。」貝里達爾是位牙醫，也是這份報告的作者之一。 他同時還指出，他們的研究是第一次針對人類的此類大規模研究，此前還在動物身上進行了實驗。結果表明，拔牙能夠切斷牙齒通往腦部的神經，從而影響記憶。 這一結果和最近日本科學家對老鼠牙齒和記憶力之間關係研究的結果非常吻合。日本科學家發現，被拔掉牙齒的老鼠對的記憶力明顯不如牙齒健全的老鼠。 這項研究迄今也未能解釋拔牙對人的記憶力到底有什麼影響。可能是因為牙齒有很多神經與大腦相連，當牙齒被拔除時，這些神經也相應消失了。 2007-12-25
