Odontogenic keratocysts: review of the literature and report of a case.

The odontogenic keratocyst is a common odontogenic cyst which accounts for 10% of all oral cysts. Odontogenic keratocysts are believed to arise from remnants of the dental lamina and are found in locations which may be encountered by periodontists. keratocysts have a distinctive histopathologic appearance and are known to be locally aggressive and have a high recurrence rate, thus requiring close long-term follow-up. Odontogenic keratocysts are one component of the basal cell nevus syndrome and all patients with odontogenic keratocysts should be evaluated for this syndrome. This paper reviews odontogenic keratocysts and presents a case treated by conservative enucleation and ultrasonic debridement of the cystic cavity with no evidence of recurrence at five years.
