Exam 1 - Radiopacities Flashcards
Exostoses are found where
On the buccal or on palatal ridge
Radiographically looks like dense bone, shows overlap in the premolar or molar region on mandibular
Torus / exostosis
What two things can you look for if you suspect a retained root tip
PDL space surrounding the RP with thin central pulp chamber
Bone sclerosis at apex of tooth, not very homogeneous, sunburst look
Condensing osteitis
Pulpal inflammation or necrosis, non vital tooth (radiopacity)
Condensing osteitis
Can regress with extraction
Condensing osteitis
Found in the mandible, usually in the posterior (periapical and periradicular regions)
Dense, well defined, obscures root but does not fuse to it, very homogenous
Idiopathic osteosclerosis
When does Idiopathic osteosclerosis usually arise
In childhood
Stays stable over time with no change
Idiopathic osteosclerosis
Are teeth non vital or vital in Idiopathic osteosclerosis
Teeth are vital
Dome shaped, faintly RP but no calcified product, arises from floor of the max sinus
Antral pseudocyst
T/F: Antral pseudocyst is a cyst
False
Antral pseudocyst symptoms
It is asymptomatic
What do you need to rule out with Antral pseudocyst
Odontogenic infection
Foul smelling/ bad breath
Tonsillar concretions / Tonsillolithiasis
accumulation in the tonsillar crypts, superimposed on the ramus on a pan. CBCT confirms
Tonsillar concretions / Tonsillolithiasis
if tonsillar concretions / Tonsillolithiasis calcify its called
tonsillolith
Benign osseous tumor, painless, slowly enlarging.
Osteoma
Can be a mass on bone surface simulating a tori , found in the condylar area and lingual posterior mandible
Osteoma
With and Osteoma, __ involvement is common
paranasal sinus
growth of an osteoma is similar to __
condensing osteitis (end stage inflammatory process) or idiopathic osteosclerosis (sclerotic bone)
If you suspect an osteoma you should rule out
Gardner syndrome
Gardner syndrome is a mutation in the
APC tumor suppressor gene
Characterized by osteomas of the facial bones
Gardner syndrome
