Abstract

Introduction: A dentigerous cyst is the most commonly developed cyst of the jaw. It is most frequently associated with impacted canines and mandibular third molars. Bilateral dentigerous cysts are rare and are generally associated with developmental syndromes or systemic diseases.

Case Presentation: We report on an eight-year-old boy who presented with a complaint of bilateral malposed first mandibular molars. There was no complaint of pain and no swelling. An intraoral examination revealed buccal tipping of both the right and left first mandibular molars with slight swelling. The overlying mucosa was completely normal and there was no tenderness on palpation. This unusual case occurrence associated with the crowns of the bilateral impacted lower second molars. There are no cases reported with bilateral dentigerous cyst involving mandibular second molars. The clinical and radiographic findings, especially the cone beam computed tomography (CBCT) views, were suggestive of dentigerous cysts.

Conclusions: After the surgical removal of the cysts, the specimens were sent for histopathological evaluation. A microscopic examination suggested infected dentigerous cysts.
