INBDE (Integrated National Board Dental Examination) Practice Exam

What type of lesion occurs in the body of the mandible of teenagers and appears as empty cavities?

1. Ameloblastoma

2. Traumatic Bone Cysts

3. Odontogenic Keratocyst

4. Dentigerous Cyst

The correct answer is: Traumatic Bone Cysts

Traumatic Bone Cysts are the type of lesions that occur in the body of the mandible of teenagers and appear as empty cavities. They are also known as simple bone cysts or solitary bone cysts. These cysts are usually seen in young individuals, often teenagers, and are characterized by their empty or fluid-filled appearance on imaging studies. The cavity within a traumatic bone cyst may sometimes be filled with blood. Ameloblastoma is a benign but locally aggressive odontogenic tumor that typically appears in the posterior mandible of adults. Odontogenic keratocysts are developmental cysts that most commonly occur in the posterior body and ascending ramus of the mandible and are often associated with the Gorlin-Goltz syndrome. Dentigerous cysts typically form at the crown of an unerupted or developing tooth and are associated with the crown of an impacted or unerupted tooth, not in the body of the mandible as described in this question.
