Sequelae of Pulpal Disease Flashcards
inflammation of the pulpal tissue:
pulpitis
What are the three classifications of pulpitis?
- reversible vs. irreversible
- acute vs. chronic
- symptomatic bs. asymptomatic
During inflammation of the pulp, describe the blood supply and collateral support:
limited blood supply; no collateral support
The expansile process of inflammation of the pulp includes:
- blood vessel dilation
- leakage of fluid into surrounding tissue
- migration of cells
pulp is alive, tooth can heal:
reversible pulpitis
pulp is dead, tooth cannot heal, even once irritant is removed
irreversible pulpitis
can occur as a result of irreversible pulpitis:
pulpal necrosis
- blood supply of tooth is severed
- tooth is discolored (grey)
pulpal necrosis
pulpitis characterized by sudden onset and symptomatic:
acute pulpitis
In acute pulpitis there is a collection of ____ ( ____)
neutrophils; abscess
exudate enclosed within chambers, builds pressure:
abscess
acute pulpitis can progress to:
- osteomyelitis
- PA abscess
pulpitis characterized by longer process and asymptomatic:
chronic pulpitis
Less irritant within the pulpal chamber occurs with:
chronic pulpitis
chronic pulpitis can progress to:
- periodontitis
- PA granuloma
- PA cyst
Chronic hyperplastic pulpitis is seen mostly in:
primary teeth (children)
What might cause the pulpal tissue to become hyperplastic in chronic hyperplastic pulpitis?
constant, long-standing irritant
Discuss the symptoms of chronic hyperplastic pulpitis:
asymptomatic
What causes the pulp polyp in chronic hyperplastic pulpitis?
proliferation of granulation tissue
due to the pulp being contained in a rigid, non-expansive tooth cavity, ____ occurs in pulpal inflammation
destruction
The presence of open or closed pulpitis occurs in:
periapical lesions
virulence of involved ____ occurs in periapical lesions
microorganism
In a periapical lesion we may see extent of ____ of ____
sclerosis; dentinal tubules
What is important in resolving PA lesions?
competency of host immune response
Cysts, granulomas and abscesses on a radiograph all appear:
radiolucent
Mass of chronically-inflamed granulation tissue:
PA granuloma
Where is a PA granuloma located?
apex of non-vital tooth
Most PA granulomas are:
asymptomatic
What is an absolute must in order to have a periapical granuloma?
NON-VITAL TOOTH
Is a PA granuloma considered a true granuloma?
NO- its just granulation tissue (not true granulomatous inflammation)
What is seen in this image?
periapical radiolucency (PA granuloma)
A periapical granuloma may develop as the initial ____ or arise after an initial ____.
periapical pathosis; periapical abscess
A periapical granuloma may transform into:
- periapical cyst
- periapical abscess
What type of inflammation is involved with periapical granulomas? What cells are present?
chronic inflammation; plasma cells, macrophages & lymphocytes
What are frequently seen with PA granulomas?
cholesterol clefts; giant multinucleated cells
This image shows:
periapical granuloma
This image shows:
periapical granuloma
This image shows:
periapical granuloma
This image shows a periapical granuloma. What helps to diagnose this?
presence of neutrophils, plasma cells, and macrophages
pathologic cavity located in soft tissue or bone lined by epithelium:
cyst
In order to have a cyst, what is an absolute must?
epithelial lining
Components of a cyst include:
- wall (connective tissue wall)
- lumen (can be filled or empty)
- lining (epithelial lining)
creates epithelial lining surrounding cavity of a cyst:
rest of malassez
The epithelial lining of a cyst is derived from:
rest of malassez
This image shows:
rest of malassez
A periapical cyst may also be called: (2)
radicular cyst or apical periodontal cyst
Pathologically, how can you differentiate a periapical cyst from a periapical granuloma?
The presence of an epithelial lining
An inflammatory cyst that is an asymptomatic, slow-growing lesion associated with the root apex of a non-vital tooth:
periapical cyst
external root resorption may be possible with:
PA cyst
Accumulation of acute inflammatory cells at the apex of a non-vital tooth:
periapical abscess
What is an absolute must for a periapical abscess?
NON-VITAL TOOTH!
A periapical abscess may arise as the initial ____ or as an ____ (____).
Initial periapical pathosis; an acute exacerbation of chronic periapical lesion (phoenix abscess)
