Abstract:

Background: The calcifying odontogenic cyst (COC) is a rare example of a developmental odontogenic cyst. COC may clinically be diagnosed as calcifying epithelial odontogenic tumour, adenomatoid odontogenic tumour, ameloblastic fibroodontoma, complex or compound odontoma, dentigerous cyst or as other types of odontogenic cysts.
Purpose: The aim is to present an unusual clinical case of COC associated with an impacted third molar of the lower jaw.
Material and methods: We present a male patient with histologically proved COC associated with a retained lower left third molar. The orthopantomography revealed an impacted third molar whose crown was surrounded by a radiolucent, circular in shape amorphous formation.
Results: The treatment of choice was third molar surgery – odontectomia and extirpation/enucleation of the cyst formation. The complete removal of the cyst was successfully performed, since after few years of follow-up there were no signs of recurrence. The result of the pathophysiological examination showed COC.
Conclusion: COC is a rare odontogenic cyst of developmental origin, which should be diagnosed timely and surgically removed.
