2
Q

What causes enamel hypoplasia/hypocalcification?

A

High fevers, distemper, endocrine dysfunction early in life

3
Q

Why will dentin stain more easily than enamel?

A

It is porous

4
Q

Not enough attachment for teeth

A

Radicular dysplasia

5
Q

How can you treat enamel hypoplasia/hypocalcification is only a few teeth are affected?

A

Conservative management, composite restoration and crown

6
Q

How do you treat diffuse enamel hypoplasia/hypocalcification?

A

Teeth brushing, regular cleanings, extractions as needed

7
Q

A

Tetracycline

8

27
Q

What are draining tracts usually caused by (that’s not a tooth abscess)?

A

FB

28
