Q

What type of nerve fibres are in dental pulp?

A

90% ADelta
10% ABeta

18
Q

Where is the Plexus of Raschkow?

A

Cell free zone

19
Q

Where is the marginal plexus?

A

around odontoblasts

20
Q

What happens to dental pulp as age increases?

A

Pulp volume decreases as number of undifferentiated cells decrease

21
Q

How does pulp sensitivity change with age?

A

Pulp sensitivity decreases as pulp becomes less vascular and contains less nerves

22
Q

What else may happen to pulp with age?

A

It may calcify/ pulp stones or denticles may arise

23
Q

What are true pulp stones?

A

tubular structure from odontoblast like cells

24
Q

What are false pulp stones?

A

calcified fibrous tissue

25
Q

Describe the reactionary tertiary dentine response.

A

TGF beta is released from carious/ demineralised dentine which increases odontoblast dentine formation.
