1What are some causes of pulpitis?
- AAnachoresis
- BDental caries
- CAttrition
- DCracked tooth syndrome
- EThermal
- FBarotrauma
2Which are some factors influencing irritation of the pulp?
- ADuration and severity of the irritant
- BHost defenses
- CApical blood flow
- DLocal anatomy of the pulp chamber
3The pulp chamber is rigid. This therefore means it has no ability to tolerate oedema. This results in this sequelae:

[blank_start]Hypoxia[blank_end]
Anoxia
Localised [blank_start]necrosis[blank_end]
More [blank_start]chemical[blank_end] mediators which exacerbate [blank_start]inflammation[blank_end]
Total [blank_start]necrosis[blank_end]- Avenous
- BHypoxia

- Einflammation
- Fchemical
4Chronic hyperplastic pulpitis is
- AIrreversible
- BReversible

- AReversible
- BIrreversible
7Acute and Chronic pulpitis are a histological classification whereas irreversible and reversible pulpitis is a clinical classification.

- EOedema
14Which of these are associated with age changes in the pulp?
- ADecreased volume
- BDecreased cellularity
- CIncreased fibrosis
- DDecreased vascularity
- EDecreased collagen
- FIncreased volume
15Age changes in the pulp may impair the response of the tissue to healing
