3 Pulpal & Periapical Diseases Flashcards
What is the differential diagnosis?
- Periapical granuloma
- Periapical abscess
- Radicular cyst
What is the most common periapical radiolucency?
(seen here)
Periapicalgranuloma
What kind of periapical radiolucency is this?
Lateral apical periodontal cyst
Why does this cyst present laterally to the root?
Due to a lateral root canal
What is one way you might be able to differentiate an abscess from a cyst on a radiograph?
widening of the PDL in abscesses
Give a differential diagnosis.
- Periapical granuloma
- Periapical abscess (shown in picture)
- Periapical cyst
This is seen after an extraction and it is determined that both facial and lingual cortical plates have resorbed. What is the diagnosis?
Periapical fibrous scar
(most common after surgical extraction, and involve loss of facial/lingual cortical plates)
What is seen with #14?
pulp stone
Biopsy reveals this is granulation tissue. What would your diagnosis be?
Chronic hyperplastic pulpitis
Give a possible diagnosis. Pt reports the growth has been there for some time.
chronic hyperplastic pulpitis
This is growing out of an extraction site 2 days post-op. What might it be?
Epulis granulomatosa (granulation tissue)
Pt reports this has been slowly growing over the previous weeks. Give a possible diagnosis.
Possible oral presentation of metastatic cancer
Pt has caries on #26 and radiolucencies on the radiograph. What might this presentation be from?
cutaneous sinus tract from a periapical abscess
These are pustules of the gums and have two names. What are they?
gum boil
intraoral sinus tract
Bilateral cellulitis of the submandibular region is consistent with what diagnosis?
Ludwig’s angina
You find the Pt has an advanced abscess involving #11. What would you call this?
cavernous sinus thrombosis
What’s happening apically with #30?
focal cemento-osseous dysplasia
What can cause the increased radiopaque areas?
pulpitis of the associated tooth can cause sclerosis of alveolar bone
