fully formed
so cannot have a standard root canal becuase nothing preventing material that we put into root canal from going into the surrounding bone so do a capping!

Answer 24

usually extraction

Question 25

What do you see radiographically with a compromized root?

Answer 25

1. acute: radiolucent line, trebecular bone patterns may obscure fracture, no periapical abnormalities
2. chronic: periapical radiolucency, loss of lamina dura, fistula?

Answer 26

1. accident or structural damage to tooth?
   1.. enamel hypoplasia
