Epulis fissuratum is a mucosal hyperplasia that results from chronic low-grade trauma induced by a denture flange. Epulis fissuratum is analogous to acanthoma fissuratum of skin.
Epulis fissuratum arises in association with denture flanges. Consequently, epulis fissuratum is usually observed in the maxillary or mandibular vestibule.
Significant morbidity does not occur with epulis fissuratum.
Most cases of epulis fissuratum are observed in whites. This, no doubt, relates to the predominance of whites as denture wearers.
Most studies indicate a clear predilection for epulis fissuratum in females. The fact that women are more likely than men to wear their dentures for prolonged periods because of their reluctance to be seen without them probably plays a significant role. In addition, more women than men wear dentures and are more likely to seek treatment. Possibly, atrophic epithelial changes secondary to menopause may influence an increased reaction to trauma in older females.
Epulis fissuratum occurs in greatest numbers in the fifth, sixth, and seventh decades, but it can be observed at almost any age. Epulis fissuratum has been described in children. The fact that the lesions are related to denture wear and chronicity of an irritative process explains the higher incidence in older individuals.
