Area of Science:

Dentistry
Dermatology
Psychiatry

Background:

Recurrent cheek biting is a rare self-injurious behavior.
It often presents to dental and dermatology specialists.
Understanding its etiology and management is crucial.

Observation:

A case of severe, recurrent cheek biting in an adult male is presented.
The behavior led to significant mucosal ulceration.
The biting pattern was stereotypic.

Findings:

The patient exhibited a stereotypic pattern of cheek biting.
Associated behaviors suggested a link to impulse control disorders.
This case underscores the oral manifestations of self-injurious behaviors.

Implications:

Dentists and dermatologists should be aware of this condition.
Cheek biting may indicate underlying impulse control issues.
Further research is needed to explore the relationship between self-injurious behaviors and impulse control disorders.
