Introduction: Calcifying epithelial odontogenic tumor (CEOT) is a rare benign, but locally infiltrating neoplasm which accounts for less than 1% of all other odontogenic tumors. The tumor is often associated with impacted teeth and is twice as prevalent in the mandible. Dentigerous cysts are developmental odontogenic cysts, commonly manifesting in the second and third decades of life. A greater incidence in men than in women with a ratio of 1.6:1 and 61.4% associated with impacted or unerupted teeth. Observation: A 17-year-old Indian male reported to the hospital with an asymptomatic lesion associated to an impacted lower first molar with the presence of radiopaque entity inside. The radiological differential diagnosis was calcifying odontogenic tumor, adenomatoid odontogenic tumor and dentigerous cyst. The lesion was completely enucleated under general anesthesia and was sent for histopathologic examination. Discussion: Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm derived from epithelial tissue, forming 0.4–3.0% of all intraosseous odontogenic tumors. A dentigerous (follicular) cyst is a developmental odontogenic cyst usually attached to the crown of an unerupted tooth lined by reduced enamel epithelium. Conclusion: The patient is still under follow-up and has not shown any signs of recurrence in past 8 months after surgery.
Key words: Calcifying epithelial odontogenic tumor (CEOT) / dentigerous cyst / adenomatoid odontogenic tumor (AOT)
