Definition
This section has been translated automatically.

Harmless mucosal calluses, especially on the cheeks, which are caused by habitual cheek chewing (so-called habitual chewing) or by the pleasurable retraction of the cheek mucosa, processes which in children and adults can develop into a habitual compulsive reaction to stress or other discomfort.

Combination with cheilophagy (lip chewing) is possible, see also artefacts.

Etiopathogenesis
This section has been translated automatically.

Conscious or unconscious sucking and chewing of the cheek mucosa.

Clinical features
This section has been translated automatically.

Strip-shaped chewed, whitish or spotty, reddened, blurred plaques in the area of the buccal mucosa with ragged lesions in the area of the tooth closing ridge. In addition, focal bleeding and erosions also occur. The anterior buccal interdental line is particularly affected, as the retro-angular area can be sucked between the teeth particularly easily.

Histology
This section has been translated automatically.

Irregular plump acanthosis with focal, racy ortho or parakeratotic cornification. No cell types. No inflammatory cells in the lamina propria.

Therapy
This section has been translated automatically.

Avoidance of chronic, artifactual, mechanical irritation. The patient must be informed about the mechanism of the skin changes, in severe cases psychotherapeutic assistance is recommended.

If the diagnosis is unclear, biopsy and histological control are indicated (to exclude precancerous leukoplakia).

Note(s)

Often associated with nightly teeth grinding (bruxism), recognizable by the heavily ground down molars.
