的家长可以看一下， 算是科普。
Q: How often should a child have dental X-ray films?
Since every child is unique, the need for dental X-ray films varies from
child to child. Films are taken only after reviewing your child’s medical
and dental histories and performing a clinical examination, and only when
they are likely to yield information that a visual examination cannot.
In general, children need X-rays more often than adults. Their mouths grow
and change rapidly. They are more susceptible than adults to tooth decay.
For children with a high risk of tooth decay, the American Academy of
Pediatric Dentistry recommends X-ray examinations every six months to detect
cavities developing between the teeth. Children with a low risk of tooth
decay require X-rays less frequently.
Q: Why should X-ray films be taken if my child has never had a cavity?
X-ray films detect much more than cavities. For example, X-rays may be
needed to survey erupting teeth, diagnose bone diseases, evaluate the
results of an injury, or plan orthodontic treatment. X-rays allow dentists
to diagnose and treat conditions that cannot be detected during a clinical
examination. If dental problems are found and treated early, dental care is
more comfortable and affordable.
Q: Will X-ray films be taken routinely?
No. X-ray films are recommended only when necessary to evaluate and monitor
your child’s oral health. The frequency of X-ray films is determined by
your child’s individual needs. If your child’s previous dentist obtained X
-ray films, request copies be sent to your new pediatric dentist to help
reduce radiation exposure.
Q: How safe are dental X-rays?
Pediatric dentists are particularly careful to minimize the exposure of
child patients to radiation. With contemporary safeguards, the amount of
radiation received in a dental X-ray examination is extremely small. In fact
, dental X-rays represent a far smaller risk than undetected and untreated
dental problems.
Q: What safeguards are used to protect my child from X-ray exposure?
Lead body aprons and shields help protect your child. Today’s equipment
filters out unnecessary X-rays and restricts the X-ray beam to the area of
interest. High-speed film, digital X-rays, and proper shielding assure that
your child receives a minimal amount of radiation exposure.
注： 我的这些帖子属于科普帖。 有些具体的病例， 由于没有看到病人， 只能根据家
长的描述给出建议， 具体治疗还要和自己的医生商议。 | l******2
发帖数: 2994 | 2 头年有一篇新的观测文章说是小儿脑瘤根照牙科X-RAY的频率跟照的年龄有关系。不记
得具体记得文章杂志了，也是只看了个摘要。我的理解，既然怀孕的时候孕妇是不能照
X-RAY的以保护胎儿，那么儿童作为胎儿的延续阶段，细胞还是应该对X-RAY比成人敏感
的，所以我觉得能不照还是不照。还有我觉得牙齿不影响咀嚼功能影响外貌的话，没有
必要弄得从头到脚的完美，平时保护好牙齿不出洞，长不齐带个牙套就行了，实在是横
着长孩子痛或影响孩子自尊心那就没办法了再照。
我很喜欢你的科普系列，但是这个X-RAY 我还是保留牙盲的意见。 | l****i
