Growth and Development Flashcards
Stages of Tooth Formation (in order)
- Bud stage
- Cap Stage
- Bell Stage (Histodifferentiation and Morphodifferentiation)
- Crown formation (Apposition and Calcification)
When does the bud stage or initiation begin?
6th week of embryonic life
What gives rise to the dental lamina?
Primary Epithelial Band
is the epithelial thickening in the region of the future dental arches
Primary Epithelial Band
gives rise to primary teeth and
permanent molars
Dental Lamina
gives rise to
permanent Incisors, canines, and premolars
Buds of Primary Predecessors
Disturbance during bud stage leads to?
absence or continued budding
Stage where tooth germ forms
Cap stage
Tooth germ is composed of?
Enamel organ
Dental Papilla
Dental Follicle
Structure that superficially resembles a cap sitting on the ball
of ectomesenchyme and forms the enamel
Enamel organ
Structure that is a ball of condensed ectomesenchymal cell and forms the dentin and pulp
Dental papilla
Structure that forms the supporting structures of the teeth
Dental follicle
Disturbance during cap stage may lead to?
Failure of tooth germ to develop and
in fewer than normal numbers of teeth
What happens during the bell stage?
Histodifferentiation and
Morphodifferentiation
Epithelium continues to invaginate and deepen until the enamel organ takes on the shape of the bell
Marks end of proliferative stage as the cell uses its ability to confine
Histodifferentiation
