Talk:Mineral trioxide aggregate

"It was developed by the research pioneer and Endodontist, Dr. Mahmoud Torabinejad at Loma Linda University."? Source? Torabinejad was the inventor of MTAD, a fluid which helps to desinfect and clean the root canal. Perhaps these two are switched?

A certain person removed the fact that MTA had the same formula as Portland Cement, but this is widely spread information:. So why is it removed??? Restored the information. —Preceding unsigned comment added by 80.200.63.131 (talk) 10:52, 29 September 2009 (UTC)

Took the first two random studies about portland cement and mta. Both said arsenic release was the same (ie. way below dangerous) regarding both materials, so the sentence "However, dental materials are required to have high purity and be lead and arsenic free, unlike portland cement." is an outright LIE. Why do i have the feeling an interested party is editing this wiki page? —Preceding unsigned comment added by 90.191.47.67 (talk) 07:44, 13 May 2011 (UTC)
