Etiology • Sporadic form is idiopathic • May be a component of Gardner’s syndrome • Excludes maxillary and mandibular tori
Clinical Presentation • Sporadic form with frontal and sphenoid sites predisposed • May be multiple • Solitary lesions rare in jaws
Radiographic Findings • Well circumscribed, dense, sclerotic • May be subperiosteal or medullary
Diagnosis • Radiographic features • Microscopic features: normal cortical and trabecular bone
Clinical Presentation • Sporadic form with frontal and sphenoid sites predisposed • May be multiple • Solitary lesions rare in jaws
Radiographic Findings • Well circumscribed, dense, sclerotic • May be subperiosteal or medullary
Diagnosis • Radiographic features • Microscopic features: normal cortical and trabecular bone
Differential Diagnosis • Tori, exostoses • Ossifying fibroma • Osteoblastoma • Focal sclerosing osteitis
Treatment • Usually none • Local resection, if compromising
Prognosis • Excellent • Little recurrence potential • When associated with Gardner’s syndrome, malignant conver-
sion of intestinal polyps is assured.
