6

- most commonly the third molars
7
Q
Hyperdontia
A

8
Q
Microdontia
A
- reduced SIZE of teeth in the dentition
9
Q
Gemination
A
“twinning”
- one tooth splits into two
- results in hyperdontia
10
Q
Fusion
A
“joining”
- two teeth join into one
- results in hypodontia
11
Q
Concrescence
A
- When two teeth are joined only be cementum
12

13
Q
Dentinogenesis imperfecta
A
- imperfect formation of dentin
14
