Frictional keratosis

Frictional keratosis
Definition
Current treatment
Oral mucosa develops hyperplasia (white elevated layer) in places where it is exposed to repetitive friction.
Problems
There is no treatment that directly targets the actual friction, except maybe wearing a dental splint (bite guard) on both the upper and the lower arch at night. But the patient compliance is very low, mostly because people find the splints uncomfortable to sleep in.
- hyperplasia on the mucosa (white thick line at the level of the occlusal plane)
- indentations on the lateral sides of the tongue
- maybe greater risk of developing oral cancer
Etiology
Solution?
Easy fix
Not easy fix
- malformed dentures
- sharp tooth edges
- chronic cheek biting (morsicatio buccarum)
- tongue thrusting
- A flat barrier between the teeth and the tongue and buccal mucous membrane.
- Stiff patches attached to the soft tissues to prevent them getting chewed on.
