What are some causes of pulpitis?
Anachoresis
Dental caries
Attrition
Cracked tooth syndrome
Thermal
Barotrauma
Which are some factors influencing irritation of the pulp?
Duration and severity of the irritant
Host defenses
Apical blood flow
Local anatomy of the pulp chamber
The pulp chamber is rigid. This therefore means it has no ability to tolerate oedema. This results in this sequelae: Local collapse of the microcirculation Anoxia Localised More mediators which exacerbate Total
Chronic hyperplastic pulpitis is
Irreversible
Reversible
Pulp necrosis is
Pulp hyperaemia is
Acute and Chronic pulpitis are a histological classification whereas irreversible and reversible pulpitis is a clinical classification.
Which of these are features of hyperaemia?
Oedema
Vasodilation
Extravasation of red blood cells
Diapedesis of leukocytes
Fibrosis
Which of these are features of acute pulpitis?
Continued vascular dilatation
Collections of PMNLs
Pulp abscess
Degeneration of odontoblastic layer
Exacerbated inflammatory process
Dark red polyp
Which of these are features of chronic pulpitis?
Infiltration by lymphocytes and plasma cells
Wide open cavity
Which of these are features of chronic hyperplastic pulpitis?
Hyperplastic granulation tissue becoming epithelialised
Large, open carious lesions
Good apical blood supply
Apical blood supply constriction
Hyperplastic granulation tissue which does not become epithelialised
Which of these are features of acute inflammation?
Oedema (due to increased permeability)
Heat and redness (due to vasodilation)
PMNL infiltration
Plasma cell infiltration
Antigenic stimulation
Which of these are features of chronic inflammation?
Lymphocyte, macrophage and plasma cell infiltration
Lymphadenopathy
PMNL infiltration only
Which of these are associated with age changes in the pulp?
Decreased volume
Decreased cellularity
Increased fibrosis
Decreased vascularity
Decreased collagen
Increased volume
Age changes in the pulp may impair the response of the tissue to healing
Pulp necrosis following injury to the blood supply is called
Coagulative necrosis
Gangrenous necrosis
Liquefaction necrosis
Pulp necrosis following breakdown of inflammatory cells is known as
Pulp necrosis following breakdown by putrefactive bacteria is known as
Some complications of pulpitis could be:
's angina Periapical disease (periapical g, cyst) (bone marrow infection) thrombosis Bacteraemia caemia Death
Which of these are ways of healing the pulp?
Removing irritant
Pulp capping
Pulpotomy
XTA
How long does it take for a dentine bridge to form
4 weeks
2 weeks
1 week
A few hours
What are the three types of pulp stones?
Free
Adherent
Interstitial
Closed
Open
Pulp stones are c bodies within the matrix of the pulp
Pulp stones may be visible in radiographs
False pulp stones contain dentinal tubules
True pulp stones contain dentinal tubules
A false pulp stone surrounded by secondary dentin is known as
Both false and true pulp stones are found more commonly in the pulp chamber than the root canal
True pulp stones bear greater resemblance to primary dentin than secondary dentin
Pulp stones are l masses of material that may resemble (or not) dentinal
True pulp stones tend to be larger than false pulp stones
