    Optical and scanning electron microscopy reveal distinct oral epithelial surface features. These findings aid in diagnosing oral pathology, including leukoplakia and carcinomas.

    Area of Science:

    • Oral pathology
    • Microscopy
    • Epithelial biology

    Background:

    • Oral mucosa exhibits variable surface morphology.
    • Understanding these variations is crucial for diagnosing oral diseases.
    • Previous studies have utilized microscopy to examine oral tissues.

    Purpose of the Study:

    • To comparatively analyze oral epithelial surface morphology using optical and scanning electron microscopy.
    • To correlate observed surface features with specific oral conditions.
    • To provide insights into cellular modifications during epithelial maturation.

    Main Methods:

    • Comparative study employing optical microscopy.
    • Scanning electron microscopy (SEM) for detailed surface analysis.
    • Examination of lip, gingival, and lingual mucosa.

    Main Results:

    • Four distinct superficial cell surface types identified: parallel microridges, honeycomb appearance, microvilli, and smooth surface.
    • A smooth surface morphology was frequently observed in leukoplakia and carcinomas.
    • Hairy tongue showed enlarged filiform papillae with cellular conglomerates, bacteria, and pseudohyphae.
    • Scleroderma presented with absent filiform papillae.

    Conclusions:

    • Surface morphology variations in oral epithelium are linked to cellular modifications during maturation.
    • Microscopic analysis of epithelial surfaces is valuable for oral pathology diagnosis.
    • Distinct morphological patterns can indicate specific pathological conditions like leukoplakia, carcinomas, hairy tongue, and scleroderma.
