— Self‐inflicted, conscious, or subconscious oral mucous membrane changes caused by a biting or a sucking habit in 17 patients are presented. The name morsicatio mucosae oris et suctio mucosae oris is proposed for this entity. The biting type lesions are characterized by an irregular flaky desquamation of the epithelial layer intermingled with minute to small erosions. Histologically, this type of lesion is characterized by flattening of the superficial layers of the epithelium with retention of bacteria, presence of large faintly stained “swollen” cells in the upper part of the stratum spinosum and basophilic stained cells just below. This microscopic picture is considered pathognomonic. The sucking‐type lesions are characterized by whitish‐grayish patches of the mucosa with some degree of chagrination in direct light. Histologically, the lesion is characterized by a compression of all layers of the epithelium. Treatment with an oral screen resulted in cure in 50% of the patients treated. The importance of motivation as part of treatment is emphasized.
