Peripheral odontogenic keratocyst causing bone resorption: Report of two cases

Abstract

Two cases of peripheral odontogenic keratocyst (POKC) of the gingiva presenting as asymptomatic nodules are described. The exceptional finding of cystic radiolucency in POKCs was observed on dental radiography in one case, which had a diameter of 10 mm. Conservative surgical excision was performed on both cases, and histopathological examination showed features consistent with keratocysts. POKC may recur and should thus be followed up like intraosseous keracysts. No recurrences were observed after 10-years in our two cases. POKC is managed by conservative treatment. Recurrences should be excised more radically. Adjunct treatment with modified Carnoy's solution or topical 5Fluorouracil should be considered. POKC should be included in the differential diagnosis of asymptomatic gingival nodules.
