    Summary

    This study evaluates dental filling biomaterials for sealing ability and durability. Gold alloys and amalgams are best for posterior teeth, while microfilled composites and bonded porcelain are suitable for anterior restorations.

    Area of Science:

    • Dental biomaterials science
    • Restorative dentistry

    Background:

    • Biomaterial selection is crucial for dental restoration longevity and biocompatibility.
    • Effective sealing of cavity walls is a primary criterion for filling materials.

    Purpose of the Study:

    • To assess dental filling biomaterials based on their ability to form a tight seal.
    • To evaluate the adhesive potential, durability, and biocompatibility of various restorative materials.

    Main Methods:

    • Assessment of biomaterials against specification criteria, focusing on seal formation.
    • Evaluation of direct or indirect adhesive potential (cementing or bonding).

    Main Results:

    • Gold inlay alloys and amalgams demonstrate reliability and good tolerance for posterior restorations.
    • Microfilled composites are indicated for small anterior cavities.
    • Bonded porcelain shows potential for larger anterior restorations, though long-term validation is pending.

    Conclusions:

    • Material choice depends on cavity location and size, prioritizing sealing and adhesion.
    • Amalgams and gold alloys remain standards for posterior restorations.
    • Advanced materials like bonded porcelain offer promising alternatives for anterior restorations.
