What is the protective function of pulp
Formation of tertiary dentine
What is the formative function of the pulp

4 influences on clinical factors of the pulp
Carious pulp exposure
Age
Periodontal disease
Previous plural trauma
Describe carious pulp exposure
Pulp exposed to caries + bacteria
What effect does age have on the pulp
Less likely to be able to reverse inflammation
3 reasons age effects the pulp
Continued dentine formation reduces pulp size
Increased calcification + fibrous components
Decreased nerves + blood vessels
2 reasons periodontal disease effects the pulp
Pulp ages prematurely
Pulp less resistant to inflammation
