Developmental Disturbances Flashcards
Affects the adult and baby teeth.
Amelogenesis Imperfecta
3 Stages of enamel formation affected in amelogenesis imperfecta.
1) Elaboration
2) Mineralization
3) Maturation
Amelogenesis Imperfecta is often associated with this.
Anterior open bite.
4 Types of Amelogenesis Imperfecta
1) Hypoplastic
2) Hypomature
3) Hypocalcified
4) Hypomature-Hypocalcified with taurodontism
AI where there’s not enough quantity of enamel.
Hypoplastic
AI where there’s normal thickness of enamel, but mineral content is low.
Hypomature
This type of AI is soft and fragile.
Hypocalcified
This AI is mottled, pitted, and associated with tricho-dento-osseous syndrome.
Hypomature-Hypoplastic with taurodontism
This defect is autosomal DOMINANT
Dentinogenesis Imperfecta
Amorphic, disorganized, atubular circumpulpal dentin.
DI
Color from DI.
Blue-brown with translucence.
Enamel is normal, but tends to chip away.
DI
DI is prone to what?
Abscesses
Crowns in DI
Bulbous or shelled with early pulp chamber obliteration in bulbous.
Large pulp chambers in shelled teeth.
Roots in DI
Short
Has bulbous or shelled crowns with short roots.
DI
Variation of DI.
Shelled teeth with large pulp chambers.
Types of DI
Shields Type 1, 2, and 3.
Osteogenesis Imperfecta is seen in this type of DI.
1
Blue sclera are seen in this type of DI.
1
Primary teeth are more affected in this type of DI.
1
Periapical RL’s and amber translucence is seen in this type of DI.
1
Both dentitions affected in this type of DI.
2
Same clinical findings as Type 1, without the osteogenesis imperfecta.
