  1. Why White lesions appear White ? By : Dr. Devi Charan Shetty Principal, Professor and HOD Department of Oral Pathology, ITS CDSR, Ghaziabad

  2. Varied appearances of White Lesions

  3. Why white lesions appear white???? Epithelium Connective tissue • Increased thickness of the epithelium • Hydration of keratin • Acanthosis • Increased fibrosis • Increased distance of blood vessels from epithelium

  4. Why white lesions appear white???? • Increased thickness of the epithelium imparts a white appearance to the oral mucosa by increasing the distance to the underlying blood vessels. Usually this thickening is a result of the increased formation of keratin. • Ability of abnormal oral keratin to evenly reflect the visible light spectrum because of the hydration of the keratin layer in a manner similar to the reaction of the stratum corneum of the epidermis to water.

  5. Why white lesions appear white???? • Acanthosis or a thickening of the spinous cell layer, edema of the epithelium, or increased fibrosis of the connective tissue thereby reducing blood vessels. • Occasionally the surface of an ulcer may appear white, due to collection of fibrin on the surface. • Further elucidation in regard to the role of lipids, keratohyaline granules, membrane-coating granules, and intercellular cement.
