Buccal bifurcation cyst (paradental cyst) defined by ultrasonography and cone-beam computed tomography.

Buccal bifurcation cyst (BBC) is an uncommon inflammatory odontogenic cyst that generally occurs at the buccal region of the permanent mandibular first molars in children aged 6-8 years. The diagnosis of BBC cannot be made from the histopathologic features; therefore, diagnosis is primarily based on specific clinical and radiographic findings. In this case report, we present the clinical and radiological findings, including ultrasonography (USG) and cone-beam computed tomography (CBCT) images, of a 10-year-old boy who was referred with a complaint of swelling on the lower right jaw.
