Abstract

Introduction: Permanent denture soft liners are widely applied in prosthodontics. The unsolved problem of Candida albicans colonization of soft denture liners is especially troubling. Recently, many research tried to enhance soft liner properties by incorporating nano fillers into the polymeric matrix. In this study BaTiO3 NPs powder was incorporated in acrylic soft liner to assess its effect on adherence of candida albicans, radiopacity and surface hardness.

Materials and Methods: Based on the findings of the pilot study the percentage (1% and 1.5% by wt. of BaTiO3 NPs) chosen to be added to soft liner. Main: one hundred specimens prepared in accordance with the tests to be conducted. Firstly, BaTiO3 NPs powder was dispersed into the monomer of the soft lining material by using probe sonicator and then, measured amount of the soft liner's powder blended into this suspension. C. albicans adherence test was performed to assess the antifungal efficacy of BaTiO3 NPs/soft liner composite. Also, radiopacity test and Shore a hardness test were performed.

Results and Discussion: there was a highly significant drop in Candida albicans adherence to soft lining material after the addition of BaTiO3 NPs. Also, the radiopacity significantly increased, but the surface hardness not significantly increased after the addition of BaTiO3 NPs.

Conclusion: the addition of BaTiO3 NPs can improve the anti-fungal properties and the radiopacity of soft denture liner, while surface hardness Non-significantly changed with the addition of BaTiO3 NPs.
