    Finishing procedures significantly impact dental composite surface roughness. Microfilled composites generally yield smoother surfaces than conventional ones after finishing, with Mylar matrix strips providing the smoothest finish.

    Area of Science:

    • Dental Materials Science
    • Surface Engineering
    • Biomaterials

    Background:

    • Dental composites are widely used restorative materials.
    • Achieving smooth surfaces is crucial for esthetics and preventing plaque accumulation.
    • Different finishing techniques can influence the surface properties of dental composites.

    Purpose of the Study:

    • To evaluate the effect of various finishing procedures on the surface roughness of microfilled and conventional dental composites.
    • To compare the surface microstructure and roughness of different composite types after finishing.

    Main Methods:

    • Surface roughness was measured using profilometry.
    • Surface microstructures were analyzed.
    • Three microfilled composites (Isopast, Silar, Superfil) and one conventional composite (Concise) were tested.

  • Finishing procedures included Mylar matrix strips, white stones, silicon carbide disks, and aluminum oxide disks.

    • Main Results:

    • Surfaces cured against Mylar matrix strips exhibited the smoothest finish, with no significant differences between composite types.
    • White stones resulted in the roughest surfaces for Isopast, Silar, and Superfil.
    • Silicon carbide and aluminum oxide disks produced smoother surfaces compared to white stones.
    • Microfilled composites generally demonstrated smoother finished surfaces than the conventional composite (Concise) across evaluated finishing instruments.

    Conclusions:

    • The choice of finishing procedure significantly influences the surface roughness of dental composites.
    • Microfilled composites offer superior surface smoothness compared to conventional composites after specific finishing protocols.
    • Mylar matrix curing provides an optimal smooth surface, minimizing the need for extensive post-curing finishing.
