Potential toxicants in alginate powders.

J F de Freitas

    Australian Dental Journal
    |August 1, 1980
    PubMed
    Summary

    Dental alginate powders contain heavy metals like lead and cadmium. Analysis revealed potential health risks from inhaling these materials, particularly lead aerosols.

    Area of Science:

    • Dental Materials Science
    • Analytical Chemistry
    • Environmental Health

    Background:

    • Dental alginate impression materials are widely used in dentistry.
    • Concerns exist regarding the potential health effects of trace elements in dental materials.

    Purpose of the Study:

    • To quantify the levels of specific heavy metals (Pb, Zn, Ba, Cd, As, Be, Hg, Sb, V) and total fluoride in dental alginate powders.
    • To assess the lead content in aerosols and aqueous extracts from set alginate materials.

    Main Methods:

    • Atomic absorption spectroscopy was employed to determine metal concentrations.
    • Conventional wet-way procedures were used for total fluoride determination.
    • Analysis of aerosolized and extractable lead from set materials.

    Main Results:

    • Significant levels of lead (Pb) and other heavy metals were detected in the alginate powders.
    • Lead was found in aerosols generated during handling and extractable from set materials.
    • Fluoride content was also quantified.

    Conclusions:

    • The presence of heavy metals, especially lead, in dental alginate powders poses a potential inhalation hazard to dental professionals and patients.
    • Further toxicological assessments are warranted to fully understand the health risks associated with these materials.
