Are there any benign radiolucent lesions of the mandible?
Are there any benign radiolucent lesions of the mandible?
• Although most radiolucent lesions with well-defined sclerotic borders are benign, MRI may reveal clinically unsuspected malignant disease. Keywords: Mandible, Radiolucent lesions, Panoramic radiography, Computed tomography (CT), Magnetic resonance imaging (MRI)
Are there tumors in the submandibular gland and space?
Mass lesions in the submandibular region may be intrinsic or extrinsic to the submandibular gland (SMG). If nonglandular, such neoplastic masses will be due to level 1A adenopathy; tumors arising from the floor of the mouth, mandible, and masticator space; or rarely, primarily in the submandibular space (SMS) (Fig.
What kind of cyst is in the mandible?
Cystic lesions periapical cyst (or radicular cyst): common dentigerous cyst (or follicular cyst of the mandible): common odontogenic keratocyst (OKC): uncommon primordial cyst of the mandible Stafne cyst (or static bone cavity): uncommon solitary bone cyst of the mandible (or traumatic or haemorraghic bone cysts)
What are the protuberances on the mandibular area?
Mandibular tori: bilaterally symmetric bony protuberances on the lingual aspect of the mandible.

Are there any nonodontogenic lesions of the mandible?
Mineralization produces lesions with varying degrees of opacity. Although these lesions are classically described as radiopaque or of mixed opacity, we prefer the more precise, biologic process–oriented term lesions with mineralization. In addition, some nonodontogenic lesions mimic odontogenic lesions at radiography.
How is the SMG related to the submandibular gland?
The mass, which on several images appeared to be possibly contiguous with the SMG, was shown to be extrinsic to the gland. This was most convincingly demonstrated on multiplanar images, which showed the facial vessels as seen in (B) ( arrows) to be compressed between the reactive lymph node and the SMG.
