    All evaluated visible light-curing cavity liners released fluoride over 17 weeks. Fluoride release levels decreased significantly over time and varied between the different dental materials.

    Area of Science:

    • Dental Materials Science
    • Biomaterials
    • Fluoride Chemistry

    Background:

    • Visible light-curing (VLC) materials are widely used as cavity liners and bases in restorative dentistry.
    • Fluoride-containing dental materials are desirable for their potential anticariogenic properties.
    • Understanding the fluoride release kinetics of new VLC liners is crucial for assessing their clinical efficacy.

    Purpose of the Study:

    • To evaluate the fluoride release characteristics of five new VLC cavity liners/bases over a 17-week period.
    • To determine if fluoride release changes significantly over time.
    • To compare the fluoride release levels among the different evaluated materials.

    Main Methods:

    • Five new VLC cavity liners/bases containing fluoride were selected for the study.

  • Fluoride release was measured over a 17-week experimental duration.
  • Statistical analysis was performed to assess changes over time and differences between materials.

    • Main Results:

    • All five tested materials demonstrated fluoride release throughout the 17-week evaluation period.
    • A statistically significant decrease in fluoride release was observed over the 17 weeks (P < .01).
    • Significant differences in the total amount of fluoride released were found among the various materials (P < .05).

    Conclusions:

    • The evaluated VLC cavity liners/bases are capable of releasing fluoride over an extended period.
    • The rate of fluoride release from these materials diminishes over time.
    • Material composition significantly influences the extent of fluoride release, suggesting varying anticariogenic potential.
