Scanning and transmission electron microscope study of pellicle morphogenesis.

T Lie

    Scandinavian Journal of Dental Research
    |May 1, 1977

    Summary

    The study reveals three distinct types of early dental pellicle: globular, fibrillar, and granular. Pellicle formation varied on different surfaces, reflecting its complex composition.

    Area of Science:

    • Oral biology
    • Biomaterials science
    • Microscopy

    Background:

    • Dental pellicle is a thin proteinaceous layer forming on tooth surfaces.
    • Understanding pellicle morphology is crucial for oral health and biomaterial interactions.

    Purpose of the Study:

    • To investigate the morphology of early dental pellicle formation.
    • To characterize different pellicle types using advanced microscopy techniques.

    Main Methods:

    • Correlated transmission and scanning electron microscopy were employed.
    • Pellicle was formed on hydroxyapatite/epoxy resin splints in vivo.
    • Splint samples were collected at various time points (2-48 hours).

    Main Results:

    • Pellicle thickness differed between apatite and epoxy resin surfaces in the early stages (first 12 hours).
    • This thickness difference became negligible by 24-48 hours.
    • Three distinct pellicle morphologies were identified: globular, fibrillar, and granular.

    Conclusions:

    • Early dental pellicle exhibits complex and variable morphology.
    • The observed variations in pellicle structure are likely due to its intricate chemical composition.
    • Identification of pellicle types provides insights into early biofilm development.
