Oral Path Exam 1 - Bone Lesion Radiopacities Flashcards
What type of bony growth?
Asymptomatic, smooth, bony growth, can show enlargment
Palatal torus
Mand torus
Exostoses
What type of bony growth?
Developmental
Palatal torus
Mand torus
Exostoses
What type of bony growth?
Stony hard, variable shape/size, overlying mucosa may ulcerate with trauma
Palatal torus
Mand torus
Exostoses
What type of bony growth?
Hard palate; midline
Palatal torus
What type of bony growth?
Lingual mandible; usually bilateral
Mand torus
What type of bony growth?
Buccal or palatal ridge; unilateral or bilateral
Exostoses
What type of bony growth?
Diagnosed by appearance; can be removed surgically if needed
Palatal torus
Mand torus
Exostoses
What type of lesion?
PDL space surrounding radiopacity with potential thin central pulp chamber and tapered shape
Retained root tips
What type of lesion?
Focal bone sclerosis associated with the apex of a tooth exhibiting pulpal inflammation or necrosis
Condensing osteitis
What type of lesion?
Uniform radioopacity
Widened PDL
85% partial or total regression w/ ext or RCT
Condensing osteitis
What is residual condensing osteitis called?
Bone scar
What type of lesion?
Most in posterior mandible
Affects children/adolescents
Idiopathic osteosclerosis
What type of lesion?
Dense, homogenous radioopacity w/ some well-defined borders and others that show spicules into surrounding normal bone
Idiopathic osteosclerosis
What type of lesion?
Can obscure root, but does NOT fuse to it; may incorporate the lamina dura
Idiopathic osteosclerosis
Are teeth vital or non-vital in idiopathic osteosclerosis?
Vital!
What type of lesion?
No radiolucent rim and no radiolucent center
Idiopathic osteosclerosis
What type of lesion?
Dense, viable bone microscopically
Idiopathic osteosclerosis
What type of lesion?
Remains static or slow increase in size until maturity; X-Ray follow-up is all that is needed
Idiopathic osteosclerosis
What type of lesion?
Common, typically asymptomatic, dome-shaped, homogeneous, faintly radiopaque lesion arising from the floor of the maxillary sinus due to accumulation of inflammatory (serous) exudate underneath the sinus mucosa
Antral pseudocyst
What type of lesion?
Cause is not known; possible adjacent odontogenic infection or sinus lining irritation from sinus infection or allergies
Antral pseudocyst
What type of lesion?
Tx = rule out odontogenic infection; only treat is there are significant symptoms (expansion, pain)
Antral pseudocyst
How do you tell the difference between an antral psuedocyst and chronic sinusitis?
Chronic sinusitis = cloudy sinus, not well-defined, pain from several teeth, headache, nasal congestion/discharge
(antral pseudocyst will look like a clear dome shape on pano)
What type of lesion?
Bacteria, foreign material and desquamated keratin accumulation in the tonsillar crypts forms compacted, foul-smelling tonsillar concretion
Tonsillar concretions/tonsillolithiasis
What type of lesion?
If it calcifies, called a tonsillolith
(looks superimposed on ramus on pano; CBCT can confirm)
Tonsillar concretions/tonsillolithiasis
What type of lesion?
Causes bad breath (halotosis)
Sensation of something stuck in throat, but otherwise asymptomatic
Tonsillar concretions/tonsillolithiasis
What type of lesion?
Variable size, single/multiple, unilateral/bilateral
Not acutely painful, but can predispose to recurrent tonsillar infection leading to pain or abscess
Tonsillar concretions/tonsillolithiasis
What type of lesion?
Tx = if symptomatic, remove with saltwater gargling or waterpik, enucleation/curettage, laser cryptolysis, or tonsillectomy
Tonsillar concretions/tonsillolithiasis
What type of lesion?
Benign osseous tumor, affecting membranous bone
Osteoma
What type of lesion?
Painless, slowly enlarging
Paranasal sinus involvement is common
Osteoma
How do you tell the difference between an osteoma in the paranasal sinus vs an antral pseudocyst in the sinus?
Antral pseudocyst is on the sinus floor
Osteoma is up higher in the sinus
What type of lesion?
Jaw lesions are associated with condylar area and lingual posterior mandible
Osteoma
What type of lesion?
Exophytic mass on bone surface (periosteal) stimulating a tori/exostoses
Osteoma
What type of lesion?
Intramedullary growth (endosteal or central) similar to end stage inflammatory process (condensing osteitis) or sclerotic bone (idiopathic osteosclerosis)
Osteoma
What type of lesion?
Histologically identical to tori, condensing osteitis, or idiopathic osteosclerosis, but with continual growth
Osteoma
What should you always rule out if you see an Osteoma?
Gardner syndrome
What type of lesion?
Autosomal dominant
Gardner syndrome
What type of lesion?
Mutation in adenomatous polyposis coli (APC) tumor suppressor gene
Gardner syndrome
What type of lesion?
One of the multiple intestinal polyposis syndromes
Gardner syndrome
What type of lesion?
Characterized by osteomas of facial bones, skin lesions like epidermoid cysts/desmoid tumors, impacted supernumerary teeth, or odontomas
Gardner syndrome
What type of lesion?
Development of precancerous polyps of the colon
Gardner syndrome
What type of lesion?
Increased risk of thyroid carcinoma
Gardner syndrome
What type of lesion?
Tx = prophylactic colectomy; removal of cosmetically problematic cysts and osteomas; genetic counseling
Gardner syndrome
