    Area of Science:

    • Dental materials science
    • Biomaterials engineering
    • Tooth structure and integrity

    Context:

    • Rotary instruments used in dentistry create a smear layer on dental tissues.
    • This layer comprises grinding debris and organic film, impacting restorative procedures.
    • Understanding the smear layer is crucial for successful dental treatments.

    Purpose:

    • To elucidate the morphology and formation mechanisms of the dental smear layer.
    • To investigate the smear layer's influence on dentin permeability and bacterial infection.
    • To evaluate the smear layer's effect on the bonding of adhesive dental materials.

    Summary:

    • The smear layer's morphology and formation are presented, highlighting its composition of debris and organic film.
