牙科X射线(dental x-ray)被认为是低剂量的。但许多研究发现,有证据表明使用牙科X射线会增加患脑癌的风险 – 脑膜瘤(meningioma)。 2012年发布的一项研究证实,对牙科X射线进行检查可增加脑膜瘤的风险。

研究人员发现这一相关性,他们从1433例患者进行分析后的数据与颅内脑膜瘤诊断为年龄20〜79岁。 病人在2006年5月1日和2011年四月28号间居住在康涅狄格州,马萨诸塞州,北卡罗来纳州,加利福尼亚州和得克萨斯州。

在这个案例研究中,患有脑膜瘤的患者报告曾经进行过咬合 (bitewing)牙科X射线成像是两倍多。

那些10岁岁或以下每年或更经常做咬翼片的比那些没有做咬翼片的患脑膜瘤的风险高40%。在10至19岁的人群中,风险提高了60%。在20至49岁的人群中,风险增加了90%,在40岁或以上的人群中,风险提高了50%。

Panorex成像在年轻时或年龄小于10岁时,脑膜瘤的风险增加了近500%。

在许多牙科诊所,牙医现在使用数字X射线,其使用相对较低剂量的X射线。尽管如此,这种较低剂量的X射线并不意味着无风险。任何数量的X射线都会增加患癌症的风险!更糟糕的是,牙医知道使用的剂量较低,这使他们有可能滥用X射线,经常使用它!

除了脑癌,牙科X射线是甲状腺癌 (thyroid cancer)的危险因素。大多数暴露于牙科X射线的患者不会很快发生癌症,这会使他们在使用牙科X射线时得到不该有的安慰。

大多数牙医并不关心牙科X光检查患者的风险。在许多情况下,他们强迫使用牙科X射线。他们否认牙科X射线的风险。许多牙科助理训练不足,往往拍摄的照片数量超过需要量。这种做法不仅会增加患者患癌症的风险,还会增加牙科助理本身的风险。(DR LU)

Dental x‐rays raises risk of meningioma

Dental x-ray is considered low dose. But lots of studies have found evidence that suggests that using dental x-ray can increase risk of brain cancer – meningioma. A study released in 2012 confirmed that exposure to dental x-ray can increase risk of meningioma.

Researchers found the link after they analyzed data from 1433 patients with intracranial meningioma diagnosed at ages 20 to 79 years who resided in Connecticut, Massachusetts, North Carolina, California and Texas between May 1, 2006 and April 28 2011.

In this case study, patients with meningioma were more than twice as likely to report having ever had a bitewing dental x ray imaging.

Those who had received bitewing films annually or more often were 40% more likely to develop meningioma among those ages 10 years or younger. Among those ages 10 to 19 years, the risk was raised by 60%. Among those ages 20 to 49 years, the risk was 90% increased and among those ages 40 or older, the risk was elevated by 50%.

Panorex imaging taken at a young age or frequently at ages younger than 10 years, the risk for meningioma was increased by nearly 500%.

In many dental clinics, dentists now use digital x-ray which uses relatively lower dose of x-ray. Still, this lower dose x-ray does not mean to be risk free. Any amount of x-ray can increase the risk of cancer! The worse thing is that dentists know the dose used is lower, which give them an excuse to abuse x-ray, as a result, they use it too often!

In addition to brain cancer, dental x-ray is a risk factor for thyroid cancer. Most patients exposed to dental x-ray will not develop cancer quickly, which can give them a false comfort with use of dental x-ray.

Most dentists do not care about the risk of dental x-ray to patients. In many cases, they force use of dental x-ray. They downplays dental x-ray. Many dental assistants are ill-trained and often take more pictures than needed. This practice not only increases risk of cancer in patients, but also dental assistants themselves.
