The Food and Drug Administration (FDA) is going to review the risks mercury-containing dental fillings called amalgams pose to patients, officials say.
美國食品和藥物管理局（FDA）將檢討含汞補牙填料(稱為汞合金)對患者構成的風險，官員說。

Mercury is a known toxin and many experts concern that vapors released from the mercury fillings would increase the risk of developing brain and kidney damage especially in children and the fetus of pregnant women.
水銀是一種已知的毒素，和許多專家擔心，從汞補牙填料釋出的蒸氣會增加發展腦和腎損害的風險，特別是在兒童和孕婦的胎兒。
On Friday, FDA agreed to review its last year's ruling on mercury-containing dental fillings that indicated amalgams are harmless for dental patients.
上週五，美國 FDA同意審查它去年在含汞補牙的裁決，那指出汞合金對牙科病人是無害的。
Many US experts including dental and medical professionals, lead by the International Academy of Oral Medicine and Toxicology (IAOMT), have provoked new challenges to FDA's last ruling, asking the administration to ban or increase the regulation on dental amalgams.
許多美國專家包括牙科和醫療專業人員，由國際口腔醫學科學院毒物（IAOMT）領道，已對美國 FDA的最後裁決挑起新挑戰，要求政府禁止或增加規管牙科用汞合金。
The American Dental Association, however, said earlier this month "there is no scientific reason to revisit" FDA's 2009 ruling and that the data has not changed since. It also added that porcelain fillings are more attractive, but not always as durable or strong as silver, especially for back teeth.

Critics have questioned scientific evidences and methods used by FDA in reaching its previous decision.

The public meeting concluded that the FDA has three options in this regard: it can continue to back silver fillings, it can urge more caution in using them or it can ban the use of these fillings all together.
