Characterization of some denture cleansers.

H J Mueller, E H Greener

    The Journal of Prosthetic Dentistry

    Summary

    Dental cleansers catalyze hydrogen peroxide (H2O2) decomposition, producing oxygen (O2) via varied mechanisms. Product differences in catalysis, CO2-H2O chemistry, and chloride (Cl-) concentration were observed.

    Area of Science:

    • Analytical Chemistry
    • Physical Chemistry
    • Materials Science

    Background:

    • Hydrogen peroxide (H2O2) is a common ingredient in dental cleansers.
    • Understanding the decomposition kinetics and mechanisms of H2O2 in these systems is crucial for product efficacy and safety.

    Purpose of the Study:

    • To investigate and compare the catalytic mechanisms of H2O2 decomposition in various dental cleanser products.
    • To analyze the aqueous chemistry, including oxygen and carbon dioxide evolution, and chloride ion concentrations.

    Main Methods:

    • Comparison of calculated reaction times for homogeneous H2O2 decomposition with measured rates in cleanser systems.
    • Long-term oxygen (O2) concentration measurements.
    • Analysis of carbon dioxide (CO2) and chloride (Cl-) ion concentrations.

    Main Results:

    • Dental cleansers exhibit both heterogeneous and homogeneous catalysis of H2O2 decomposition.
    • Different products show distinct decomposition pathways: some primarily yield O2, while others involve the perhydroxyl ion (HO2-).
    • Efferdent and Polident show contributions from the CO2-H2O system, while Kleenite has significantly higher Cl- concentrations.

    Conclusions:

    • The catalytic process for H2O2 decomposition varies significantly among dental cleanser brands.
    • Aqueous chemistry, including CO2-H2O interactions and Cl- levels, differentiates cleanser performance and mechanisms.
