15 Questions
What is the definition of tooth eruption?
The emergence of teeth from their developmental position in the bone to the functional occlusal position in the dental arch.
When does the eruptive phase begin?
When the root starts to form.
What are the three phases of tooth eruption?
Pre-eruptive phase, eruptive phase, and functional phase.
Name three developmental processes and factors related to tooth eruption.
Elongation of the root, force exerted by vascular tissue, growth of dentine.
What happens after the emergence of the crown of the tooth through the alveolar bone?
The enamel organ degenerates, becomes thinner, and is known as reduced enamel epithelium.
What is the term for the phase of tooth eruption in which the tooth germ undergoes intraosseous and supraosseous movement until it enters the oral cavity?
Eruptive phase
Which factor contributes to the movement of teeth to maintain their positions of functional occlusion and towards the occlusal plane?
Force exerted by vascular tissue around and beneath the root
What happens to the enamel organ after the emergence of the crown of the tooth through the alveolar bone?
It becomes thinner and is known as reduced enamel epithelium
Which phase of tooth eruption is observed before the beginning of root formation, during which the tooth germ moves within the tooth crypt?
Pre-eruptive phase
What developmental process contributes to the elongation of the tooth root during eruption?
Dental follicle growth
During which phase of tooth eruption does the enamel organ degenerate and become thinner?
Post-eruptive phase
What factor contributes to the elongation of the tooth root during the eruptive phase?

Which process occurs after the tooth germ undergoes intraosseous and supraosseous movement until it enters the oral cavity?
Eruption of the crown
What contributes to the movement of teeth to maintain their positions of functional occlusion and toward the occlusal plane?
Growth and pull of periodontal membrane
What happens to the enamel organ after the emergence of the crown of the tooth through the alveolar bone?
