title: Unacceptably high levels of fluoride in commercial preparations of silver fluoride.
abstract: Instead of expected fluoride ion concentrations of around 60,000 ppm, commercial preparations of 40 per cent aqueous silver fluoride were found to contain 120,000-127,000 ppm. Information received from the Western Australian Chemistry Centre which provided independent confirmation of the higher than expected [F] indicates that the currently available commercial preparations contain silver difluoride rather than silver fluoride. In view of the potential of fluoride-containing products such as dentifrices (1000-1500 ppm F) and topical fluoride gels and solutions (6000-12,000 ppm F) to cause adverse effects if excessive quantities are ingested, any product that contains 120,000 ppm [F] should be regarded as carrying a high risk of toxicity when used on young children.
