ABSTRACT
Keratocystic odontogenic tumor or Odontogenic keratocyst is a benign but one of the most locally aggressive type of developmental odontogenic cyst. Due to its invasive abilities in the bone and its high recurrence rate, it shares features of a cyst or a neoplasm and continues to riddle clinicians and researchers. Clinical and radiological expertise lies in diagnosing such lesions which present themselves as a coincidental finding in a routine out patient department. We report an unusual occurrence of a Collateral Odontogenic Keratocyst between the roots of two mandibular molars.
ABSTRACT
Dentigerous cyst is a developmental odontogenic cyst which originates through alterations of the reduced enamel epithelium in an unerupted tooth after the crown has been fully formed. Dentigerous cysts associated with supernumerary teeth are rare and constitute 5–6% of all dentigerous cysts. Supernumerary teeth should be examined very carefully to prevent possible effects on adjacent regular teeth and possible cystic development. We report a rare case of mid palatal swelling due to a dentigerous cyst associated with an impacted supernumerary in an elderly patient.
