Tooth Development And Eruption Part 1 Flashcards
What is odontogenesis?
Odontogenesis is the process of tooth development.
Can developmental disturbances occur during odontogenesis?
Yes, developmental disturbances can occur during each stage of odontogenesis.
How can developmental disturbances affect the tooth?
They can affect the physiological processes taking place during development.
What are the potential clinical implications of developmental disturbances in odontogenesis?
These disturbances may have ramifications that affect the clinical treatment of a patient.
What does the term ‘dentition’ refer to?
The term ‘dentition’ refers to the natural teeth in the jaws.
How many types of dentitions are there?
There are two types of dentitions: primary and permanent.
When does the primary dentition develop?
The primary dentition develops during the prenatal period.
How many teeth are included in the primary dentition?
The primary dentition consists of 20 teeth.
What happens to the primary dentition teeth before the permanent teeth erupt?
They will be exfoliated (shed).
How many teeth are included in the permanent dentition?
The permanent dentition consists of 32 teeth.
How does odontogenesis take place?
Odontogenesis takes place in stages, which occur sequentially for both dentitions.
When does odontogenesis of the primary dentition begin?
It begins between the sixth and seventh week of prenatal development, during the embryonic period.
What are the initial identifiable stages in tooth development after initiation?
The initial identifiable stages are the bud stage, cap stage, and bell stage.
What stage follows the bell stage in odontogenesis?
Odontogenesis progresses to the apposition stage after the bell stage.
What happens during the apposition stage?
The apposition stage involves the formation of partially mineralized dental tissue types, including enamel, dentin, and cementum.
What is the final stage of odontogenesis?
The final stage is the maturation stage, where the dental tissues fully mineralize.
What physiologic processes take place during odontogenesis?
The physiologic processes include induction, proliferation, differentiation, morphogenesis, and maturation.
Are the processes of odontogenesis separate or overlapping?
Except for induction, many of these processes overlap and are continuous during odontogenesis.
Although the physiologic processes during odontogenesis may occur simultaneously,
one process will tend to be predominant, marking each stage of odontogenesis.
What is the first stage of tooth development?
The first stage of tooth development is the initiation stage.
What physiologic process is involved in the initiation stage?
The initiation stage involves the physiologic process of induction.
What is induction in the context of tooth development?
Induction is an active interaction between embryologic tissue types.
What happens at the beginning of the 6th week of prenatal development?
At the beginning of the 6th week, the stomodeum (primitive mouth) is lined by ectoderm.
What does the outer part of the ectoderm give rise to?
The outer part of the ectoderm gives rise to the oral epithelium.
