as the oral mucosa
ages
DEFINITION 93
1) It is thinner, smoother (due to flattening of surface ridges &
cells), less moist (minor salivary glands atrophy & major glands
are less active). 4) Increased fibrosis-due to decreased cellular
activity. 5) Calcifications appear in the lamina propria & PDL. 6)
Ability to repair is reduced & healing time is increased. 7) Apical
migration of the gingiva. 8) Medication side effects.
