    Acidified sodium fluoride solutions significantly increase fluoride levels on etched enamel compared to neutral solutions. This finding is crucial for optimizing fluoride uptake during orthodontic bonding procedures.

    Area of Science:

    • Dental research
    • Materials science

    Background:

    • Orthodontic bonding requires enamel preparation, often involving etching.
    • Fluoride application is used to enhance enamel resistance to demineralization.
    • The efficacy of fluoride uptake can be influenced by the solution's pH.

    Purpose of the Study:

    • To compare the effectiveness of neutral and acidified sodium fluoride solutions in increasing enamel fluoride levels after etching.
    • To determine the optimal pH for topical fluoride application in the context of orthodontic procedures.

    Main Methods:

    • Enamel surfaces were subjected to etching, simulating orthodontic bonding preparation.
    • Topical application of both neutral and acidified sodium fluoride solutions was performed.
    • Enamel fluoride levels were quantified after treatment.

    Main Results:

    • Acidified sodium fluoride solutions resulted in significantly higher enamel fluoride levels compared to neutral solutions.
    • The pH of the sodium fluoride solution directly impacts fluoride retention on the etched enamel surface.

    Conclusions:

    • Acidified sodium fluoride solutions are more effective in enhancing enamel fluoride content post-etching.
    • Utilizing acidified fluoride solutions may offer improved protection against caries during orthodontic treatment.
