INFLAMMATORY DENTIGEROUS CYST: A RARE CASE REPORT

Dr. Ifzah, Dr. Nazia Lone* and Dr. Mohsin

ABSTRACT

Introduction: A dentigerous cyst is a cyst that encloses the crown of an unerupted tooth by expansion of its follicle and is attached to its neck. It is usually associated with impacted or unerupted teeth with mandibular third molars, maxillary canines and mandibular premolars being the most frequently involved teeth. Rarely, a dentigerous cyst is associated with odontome, deciduous teeth and supernumerary teeth. We hereby report a rare case of a 12-year-old boy with dentigerous cyst associated with deciduous mandibular molars. Case Report: A 8 year old male patient reported to the department of Pediatric Dentistry, Govt Dental College and Hospital with the chief complaint of painless swelling in right lower back tooth region since 2 months. . The panoramic radiograph revealed a large, well- defined unilocular radiolucent lesion with sclerotic borders on right side of mandible. Diffential Diagnosis: Based on the clinical, radiological and histopathological findings a differential diagnosis of dentigerous cyst was made and marsuplization was decided for the lesion. Treatment: In our case, marsupilization of the infected cyst was done because of the involvement of permanent teeth in the cyst. Conclusion: Dentigerous cyst is most commonly associated with impacted third molars. In the present case we reported a rare case of inflammatory dentigerous cyst associated with primary mandibular molars and impacted second premolar.
