    Summary

    This study assessed permanent luting cement solubility in dentures. Glass ionomer and silicophosphate cements showed the lowest solubility over six months.

    Area of Science:

    • Dental Materials Science
    • Biomaterials Research
    • Clinical Dentistry

    Background:

    • Assessing the in vivo solubility of permanent luting cements is crucial for understanding their longevity and performance in the oral environment.
    • Previous studies have investigated cement solubility, but standardized in vivo methods are needed for reliable comparisons.
    • Permanent luting cements are essential for securing dental prostheses, and their degradation can impact treatment success.

    Purpose of the Study:

    • To evaluate a novel method for comparing the in vivo solubility of permanent luting cements.
    • To quantify and compare the solubility of nine different permanent luting cements under simulated oral conditions.
    • To validate the findings against existing clinical solubility data.

    Main Methods:

    • Permanent luting cements were placed into standardized crypts within complete dentures.
    • A vented cover design facilitated continuous fluid access, simulating oral fluid exposure.
    • Cement loss was measured after a 6-month in vivo evaluation period for nine distinct cement types.

    Main Results:

    • Glass ionomer cements (at two powder-liquid ratios) and silicophosphate cements exhibited comparable and minimal solubility.
    • These specific cement types demonstrated significantly lower solubility compared to the other seven cements tested.
    • The observed solubility patterns align closely with results from two prior clinical solubility studies.

    Conclusions:

    • The evaluated method provides a reliable means for assessing in vivo luting cement solubility.
    • Glass ionomer and silicophosphate cements present favorable solubility profiles for long-term clinical use.
    • This research contributes to the selection of durable luting cements in restorative dentistry.
