    Area of Science:

    • Oral health research
    • Dental caries prevention

    Background:

    • Dental caries is a significant oral health issue.
    • Fluoride is a key agent in preventing tooth decay.
    • Understanding fluoride's interaction with plaque pH is crucial.

    Purpose of the Study:

    • To investigate the effect of sucrose-containing fluoride tablets on salivary fluoride levels and interproximal plaque pH.
    • To compare the pH changes induced by fluoride tablets versus placebo tablets.

    Main Methods:

    • Simultaneous telemetry of salivary fluoride and interproximal plaque pH.
    • Utilizing fluoride and pH sensors near dissolving tablets.
    • Administering sucrose-containing fluoride tablets (1.0 mg fluoride/42 mg sucrose) and placebo tablets.

    Main Results:

    • Fluoride tablets caused slight plaque pH depressions (6.7 to 6.0) with salivary fluoride increases up to 190 ppm.
    • Placebo tablets without fluoride led to significant pH drops to 4.2 due to acid formation.
    • Fluoride mitigated the pH drop caused by sucrose.

    Conclusions:

    • Fluoride effectively counteracts the acidogenic potential of sucrose in plaque.
    • Topical fluoride delivery via tablets can help manage cariogenic challenges.
    • Further research into optimized fluoride delivery systems is warranted.
