牙龈萎缩艾滋病的关系
  更新时间：2009-8-5 1:15:00
    牙龈萎缩艾滋病关联1、牙龈萎缩相当多见，尤其在老年人中更为普遍。全国牙防组抽样调查报告表明。我国12岁儿童中牙周不健康的多达69％。成年人和老年人中有牙龈萎缩现象的高达82％和97％。很多人认为。牙龈萎缩是人上了年纪出现的自然现象。但是有证据表明，一些牙龈健康的高龄者并不发生牙龈萎缩。有人估计，成年人的健康牙周组织也有缓慢而微小的附着丧失。每10年约为0．17毫米，到70岁时。牙周组织的退缩仅为0．5毫米，肉眼不易觉察且无症状。一般情况下已发生牙龈萎缩。就不会再恢复到以前的状况。这是由牙龈组织的特殊结构所决定的。牙龈萎缩常使裸露的牙根对冷热的温度变化及酸性食物等异常敏感，妨碍进食，降低生活质量。

    牙龈萎缩艾滋病关联2、牙周病导致牙齿龈缘部分存在的牙石长期得不到清理，细菌滋生，刺激长期存在。造成牙龈萎缩，从而导致牙冠变长。牙齿松动。王女士牙龈萎缩就是因为患有严重的牙周病所致。在洁牙前，因牙龈萎缩而暴露的牙根被牙石所覆盖。吃饭时没什么症状，但洁牙后，牙石被去除。牙根暴露，遇冷遇热就酸了。

    牙龈萎缩艾滋病关联3、刷牙不当使用过硬的牙刷、牙膏中摩擦剂的颗粒太粗，或者是使用拉锯式的横刷法等。尤其好发于牙弓弯曲处。如尖牙、前磨牙部位。譬如第一例中的张小姐。因为想把自己牙齿刷白点，刷牙时总是用力横刷，从而导致了两个尖牙的牙龈萎缩。镶牙不当镶牙不当也可导致牙龈萎缩。例如。活动假牙的卡环过低，基托边缘压迫牙龈缘等。牙齿解剖变异等健康的牙龈像一道屏障。紧紧包裹住牙根。防止牙石、酸性物质的侵蚀。
The relationship between AIDS gingival atrophy

     AIDS associated gingival atrophy 1, gums shrink quite often, especially more common in the elderly. National sample survey of dental anti-group report. China's 12-year-old children in an unhealthy periodontal up 69%. Adults and the elderly in the gums shrink up to 82% and 97% respectively. Many people think that. Shrinkage of the gums is a natural phenomenon of age. However, there is evidence that some senior citizens gums healthy gums do not atrophy occurred. It is estimated that the health of the periodontal tissues of adults are slow and small attachment loss. Every 10 years is about 0.17 millimeters, to 70 years of age. Periodontal tissues of the back of only 0.5 mm, the naked eye and difficult to detect asymptomatic. Under normal circumstances gum shrinkage has occurred. Will no longer return to the status quo ante. This is determined by the special structure of the gingival tissue determined. Shrinkage of gums often the root exposed to hot and cold temperature changes and is extraordinarily sensitive to acidic food, etc., hinder eating, lowering the quality of life.

     2 AIDS associated gingival atrophy, periodontal disease leading to tooth gingival margin of the existence of some long-term lack of clean-up of tartar, bacteria and stimulate a long time. Atrophy caused by gums, resulting in longer crown. Loose teeth. Ms. Wang is shrinking gums because the result of suffering from severe periodontal disease. Cleaning teeth in the former, due to shrinking gums and exposed roots were covered by calculus. No symptoms, when to eat, but after cleaning teeth, dental calculus was removed. Root exposure, when hot-cold-shouldered on the ache.

     AIDS related gums shrink 3, the improper use of strong brush toothbrush, toothpaste friction agent in the particles are too coarse, or the use of see-saw type of cross-brushing method. In particular, made a good bend in the arch. Such as the canine, premolar site. For example, in the first case of Miss Zhang. Because the want their white teeth, the brush when the brush is always horizontal force, resulting in two of the gums to shrink canine. Improper setting teeth setting teeth can also lead to improper shrinking gums. For example. Activities of clasp dentures too low, base edge of the brink of oppression, such as gums. Anatomic variations, such as dental health gum as a barrier. Root live tightly wrapped. The prevention of tartar, acid erosion.
