A multicentre study of 268 cases of calcifying odontogenic cysts and a literature review

Abstract

COC is a rare lesion. Novel data on the clinicopathological features of 268 cases have been added to the literature. Data regarding gender and age of the Brazilian patients reported herein contrast with findings of case series and retrospective studies reported elsewhere.

Calcifying odontogenic cyst: A case report

“…A COC is an uncommon lesion in the oral cavity with a cystic cavity, lined by odontogenic epithelium of variable thickness containing focal ghost cells. The COC can arise at any site in the oral cavity with cases occurring most frequently in the anterior maxilla, followed by the posterior mandible. The COC is thought to evolve from odontogenic epithelial remnants confined within the maxillary and mandibular bones or gingival tissues.…”

“…COCs are often associated with impacted teeth. However, the displacement of an adjacent tooth is rarely reported and is observed in the case discussed.…”

“…Incidence is almost equally distributed between the maxilla and the mandible. Reports on gender prevalence vary in the literature but, the occurrence of COCs is approximately equal in males and females. There appears to be a slight predilection for Caucasians.…”

“…Reports on gender prevalence vary in the literature but, the occurrence of COCs is approximately equal in males and females. There appears to be a slight predilection for Caucasians. The incidence of root resorption is 75–77% of cases.…”

“…Primary clinical presentations vary from loosening of teeth to increasing swelling. This lesion can occur at any age with incidence most commonly in the second decade of life. Incidence is almost equally distributed between the maxilla and the mandible.…”
