|
idiopathic protuberances of bone, midline palate and Lingual of anterior mandible. Esp. Asian, native American, Inuit populations
|
Tori
|
|
|
BFOL’s stands for:
|
Benign Fibrooseous Lesions (of the jaws)
|
|
|
bone mass on buccal alveolar bone
|
Exostoses
|
|
|
Asian and Native American
|
Tori
|
|
|
normal bone is replaced by benign fibrous CT + immature and/or cementum like material. A benign abnormal change in the bone quality (not really a true dysplasia).
|
Cementoosseous dysplasia
|
|
|
affects apices of mandibular incisors, more common in Black females 20-30’s causing multiple RL (à opaque w/t)lesions of VITAL teeth. Tx: none
|
Periapical cementoosseous dysplasia (periapicocemmento dysplasia)
|
|
|
Black females age 20-30's
|
Periapical cementoosseous dysplasia (periapicocemmento dysplasia):
|
|
|
Slow expansion of jaws and craniofacial bones à well circumscribed defined border, mixed RL (variable presentation). Tx: complete surgical excision.
|
Ossifying fibroma
|
|
|
Developmental disorder caused by the mutation of GNAS1 Gene à abnormal fibrous CT = not well circumscribed immature woven bone with dysplasia (will not mature). 3 types: monostatic (single part of body), polystatic (multiple), McCune-Albright syndrome (polyostotic fibrous dysplasia, café-au-lait, endocrine abnormalities). Can involve jaws and other bone, 10-20 years old – normally stabilizes after puberty, classic “Ground Glass” appearance. Tx: recontour after growth stops.
|
Fibrous dysplasia
|
|
|
same as PA Cementoosseous Dysplasia but NOT in mandibular incisors, 90% women, RL/mixed, may need to be biopsied.
|
Focal cementoosseous dysplasia
|
|
|
jaw and craniofacial bone expansion
|
Ossifying fibroma
|
|
|
90% women
|
Focal cementoosseous dysplasia
|
|
|
exuberant form, esp black women, multiquadrant +/- RL, prone to osteomyelitis
|
Florid cementoosseous dysplasia
|
|
|
GNAS1 Gene mutation; histo: 'ground glass' look
|
Fibrous dysplasia
|
|
|
cementoosseous dysplasia that is found EVERYWHERE
|
Florid cementoosseous dysplasia:
|
|
|
Nocturnal pain (most others cause no pain) relieved by NSAIDs. Resembles other BFOLs esp mixed radiolucent/radiopaque. Tx: excision.
|
Osteoblastoma(>1.5-2 cm)/Osteoid Osteoma(<1.5-2 cm)
|
|
|
Benign proliferation of bone common in paranasal sinuses. No Tx necessary. Multiple osteomas à think Gardner’s syndrome (numerous impacted teeth, intestinal premalignant polyps).
|
Osteoma
|
|
|
Osteoblastoma or Osteoid Osteoma is <1.5-2cm?
|
Osteoid Osteoma
|
|
|
multiple Osteoma's, numerous impacted teeth, intestinal premalignant polyps
|
Gardner’s syndrome
|
|
|
Night pain
|
Osteoblastoma/Osteoid Osteoma
|
|
|
Bone proliferation in PARANASAL SINUSES
|
Osteoma
|
|
|
area of increased bone density of unknown etiology = increased/well defined RP usually< 1cm, NOT associated with inflamed tooth.
|
Ideopathic osteosclerosis aka dense bone island
|
|
|
reaction due to chronic pulpal inflammation. Does not require aggressive Tx like true osteomyelitis.
|
Condensing Osteitis aka focal sclerosing osteomyelitis
|
|
|
"dense bone island"
|
Ideopathic osteosclerosis
|
|
|
"focal sclerosing osteomyelitis"
|
Condensing Osteitis
|
|
|
Benign proliferation of multineuclated giant cells of jaws, most multilocular / some unilocular. Histo: multinucleated giant cells (identical to cherubism = multiple CGCG’s of the jaw, peripheral giant cell granuloma and “brown tumor.”
|
Central Giant Cell Granuloma
|
|
|
Central (intraosseous) vascular malformation à teeth my extrude +/- spontaneous bleeding/bruit. Radio: most multilocular, “soap bubble” +/- sun-ray-like appearance.
|
Hemangioma of Bone
|
|
|
histo: multinucleated giant cells
|
Central Giant Cell Granuloma
|
|
|
'soap bubble' x-ray
|
Hemangioma of Bone
