    Area of Science:

    • Biomaterials Science
    • Dental Materials
    • Tissue Engineering

    Context:

    • Dental composites are widely used restorative materials.
    • Assessing the biocompatibility of dental materials is crucial for patient safety.
    • Human gingival cell cultures provide a relevant in vitro model for evaluating oral tissue response.

    Purpose:

    • To evaluate the tissue tolerance of three dental composites: Nuva Fil, Vytol, and Estic microfil.
    • To compare the cytotoxicity of nonpolymerized and polymerized states of these materials.
    • To identify potential adverse cellular reactions in human gingival fibroblasts.

    Summary:

    • Cell cultures of human gingiva were used to assess the tissue tolerance of Nuva Fil, Vytol, and Estic microfil composites.
    • Nuva Fil and Vytol demonstrated extremely low cytotoxicity in both nonpolymerized and polymerized forms.
    • Estic microfil exposure resulted in the observation of multinuclear fibroblasts, suggesting a potential for adverse tissue response.

    Impact:

    • This study provides critical biocompatibility data for dental restorative materials.
    • Findings highlight the need for careful material selection in dental procedures to ensure optimal tissue integration.
    • The observed cellular response to Estic microfil warrants further investigation into its long-term effects and potential clinical implications.
