口腔科的X 光是否有害?

牙医诊所的工作人员常说牙科 X光剂量很小,和日常生活或坐飞机被放射线照射差不多。问题是日常生活中的射线散布全身,牙科 X光却是有方向性的。整篇文章很有意思。。。

It's impossible to tell, because there are no good studies showing the right number of X-rays to give someone who isn't having any particular dental problem. While some dentists do bitewing X-rays every six months on a healthy patient, others hardly ever do them, relying instead on a visual examination of the mouth with a sharp explorer and a mirror.
It's an important question, since dental X-rays are the only form of medical radiation received on a regular basis by large numbers of American men, women, and children.
"It's crazy," says Dr. Nicholas Dello Russo, an instructor in the department of oral and maxillofacial surgery at the Harvard University School of Dental Medicine. "We're doing an experiment on a vast number of people in this country and we have no idea how it will play out in the next 15 or 20 years."

每年牙医检查都要给我们照,x ray, 给孩子照时我问她是否辐射不好,可不可以不照?她都说比微波炉的辐射小,我觉得她是应付我,如 -蒲公英的梦想555- 给 蒲公英的梦想555 发送悄悄话 蒲公英的梦想555 的个人群组 (0 bytes) () 07/16/2017 postreply 13:59:46

只要换牙医,必照无疑,不管最近是否已经照过一次,这是挣钱的第一步。牙医工资那么高,坑了多少人啊! -lawattaction- 给 lawattaction 发送悄悄话 lawattaction 的个人群组 (0 bytes) () 07/16/2017 postreply 17:45:11

CNN文章的中心思想:避免儿童期射线过度暴露,平时做好牙保健,了解牙科协会的建议,不要被牙医忽悠每半年拍局部或全景X光。 -聽風- 给 聽風 发送悄悄话 聽風 的个人群组 (0 bytes) () 07/16/2017 postreply 17:56:03
