* Growth (Eruption) of Teeth


Size Of Teeth:

1. Microdontia
2. Macrodontia

1. Germination
2. Fusion
3. Concrescence
4. Di laceration
5. Talon cusp
6. Dens in Dente
7. Dens Evaginatus
8. Taurodontism
9. Supernumerary Roots

Number Of Teeth:

1. Anodontia
2. Supernumerary Teeth
3. Pre-Decidious Teeth
4. Post-Permanent Teeth

Structure Of Teeth:

1. Amelogenesis Imperfecta
2. Environmental Enamel Hypoplasia
3. Dentinogenesis Imperfecta

4. Dentin Dysplasia
5. Regional Odontodysplasia
6. Dentin Hypocalcification

Growth (or) Eruption Of Teeth:

1. Premature Eruption
2. Delayed Eruption
3. Eruption Sequestrum
4. Multiple Unerupted Teeth
