Normal Color of Oral Mucosa

1). dark pink (reddish) to very pale (almost white).

2). thickness of epithelium, degree of keratinizationA). thicker epithelium: more keratinized, more fibrous and

less vascular subepithelial connective tissue--color is whiter; hard palate, fixed gingival, dorsal surface of the tongue.

B). darker pink or more reddish in color: less keratin, more vascular tissues; vestibule, floor of the mouth, ventral surface of the tongue, retromolar regions.

Leukoedema non-malignant variation of normal

mucosa. most often at buccal mucosa, but also

other sites (labial mucosa, soft palate). most often seen adults > 40 yrs. clinical features:

early stage: firmly opalescence; later stage: definite grayish white cast

with coarsely wrinkle surface which cannot be removed with a tongue blade, but will disappear on stretching.

(if injury: red eroded area, mimic cheek biting).
