Orthokeratinised Odontogenic Cyst Mimicking Mandibular Paradental Cyst: A Rare Case

Swaroop Savanur, Shitalkumar G Sagari, Roopa Babannavar, Bishen A Kundendu

Abstract


The orthokeratinised odontogenic cyst is a rare epithelial developmental cyst of the jaws. This lesion resembles odontogenic keratocyst which is commonly found in the mandible, and can become quite large due to its rapid growth and its extension into the adjacent structures. Clinically the parakeratinising odontogenic keratocyst’s are characterized by aggressive growth and tendency to recur after surgical treatment in contrast to orthokeratinised odontogenic keratocyst. We report a rare case with no clinical signs and symptoms other than pain in relation to left posterior mandibular region. The intraoral soft tissues adjoining to third molar are absolutely normal, whereas radiographic appearance were suggestive of Paradental cyst and periodontal cyst. The excised tissue specimen diagnosed as orthokeratinised odontogenic cyst.
