Odontogenesis is the process of tooth What is odontogenesis, and what are its stages?
development and can be divided into:
1)Initiation stage
2)Bud stage
3)Cap stage
4)Bell stage
5)Crown/Maturation stage
Odontogenesis begins during fetal When does odontogenesis begin, and what dentition is
development and involves the formation of involved?
the deciduous (primary) dentition
at 18 weeks there is dentin and functional What happens between week 18-32 weeks during fetal
ameloblasts in deciduous teeth (primary development in relation to odontogenesis?
dentition) and at 32 weeks there is dentin
and functional ameloblasts in permanent
teeth
A horseshoe-shaped band of thickened What structure forms during the initiation stage of
epithelium forms, called the primary oral odontogenesis , and what does it look like (what kind of
epithelium or primary epithelial band epithelium forms)?
(stratified squamous epithelium)
seated on a basement membrane in the what does the primary oral epithelium sit on top of?
ectomesenchyme region
,primary oral epithelium What is shown by the pink and green band in this image?
primary oral epithelium; shows bud stage What are the black arrows pointing to in this image and in
what stage is the structure?
The dental lamina forms from the What is the dental lamina, and how does it form?
invagination of the oral epithelium into the
underlying ectomesenchyme

center, secreting genetic factors to induce
the differentiation of ectomesenchymal
cells into tooth-forming tissues
During this stage the primary oral in the initiation stage what structure is coordinating the tooth
epithelium is coordinating the tooth development through what feature?
through the dental placode
ectomesenchyme A
Dental placode B
dental placode A
Ectomesenchymal cells are stem cells What is the significance of ectomesenchymal cells in tooth
(pluripotent cells) that can be differentiated development?
into different types of cells and give rise to
tooth-forming tissues
The dental lamina grows into the What happens to the dental lamina during the bud stage?
mesenchyme, forming the tooth bud, which
is the deepest part of the dental lamina
Ectomesenchymal cells condense around What changes occur in the ectomesenchymal cells during the
and beneath the tooth bud, assuming bud stage?
odontogenic potential and coordinating
tooth formation by secreting genetic factors
The bud stage is more tube-like with How does the structure of the tooth bud differ from the
additional growth compared to the initiation initiation stage?
