The Council on Dental Therapeutics is one of many councils under the American Dental Association and was created in 1930 to oversee the evaluation of dental products. In 1931, the Council established the ADA's Seal Program and awarded the first ADA Seal of Approval to a brand of cold liver oil recommended as a food supplement to promote strong teeht and healthy gums. Neither Sargenti Paste nor any other paraformaldehyde containing root canal sealer has ever been given the ADA seal of approval.
Theis link is to excerpts from the 2006 ADA/PDR Guide to Dental Therapeutics where Sargenti Paste and, in general, unapproved drugs are discussed along with a dentists's "duty of disclosure" when these materials are used.
Sargenti using dentists are not following the written guidelines established by the ADA, in general, and the ADA's Council on Dental Therapeutics.
"Paralegally, the Council on Dental Therapeutics of the American Dental Association reissued a resolution against paraformaldelyde sealers that concluded “that the FDA has not approved any products with this formulation, [so] the Council cannot recommend the use of these products at this time(232). This report buttressed two previous negative pronouncements by Council in 1977 and 1987"(233, 234).
