Epulis fissuratum is a mucosal hyperplasia that results from chronic low-grade trauma induced by a denture.
Epulis fissuratum is analogous to acanthoma fissuratum of skin
The cause of epulis fissuratum is chronic low-grade irritation from an ill-fitting denture. Frequently, this is the consequence of resorption of the alveolar ridge so that the denture moves further into the vestibular mucosa, creating an inflammatory fibrous hyperplasia that proliferates over the flanges.
Race- mostly seen in whites
Sex-more in women than men.
Age-more seen in 5-6 th decades
encompass the border of the denture flange. The edge of the denture usually fits in a groove between the
folds. The lesions are most frequently observed at the facial aspect of the denture. The occurrence of this
on the lingual surface is unusual. They are more often observed in the anterior portion of the jaws;
however, a predilection for the maxilla or the mandible does not seem to exist.
Surgical - Surgically excise the epulis fissuratum because even removal of the offending stimulus (ie, denture) will not result in complete resolution. In addition, correct the denture; otherwise, the lesion will recur. Either make a new denture or reline the old denture. The use of laser therapy is also seen.
