15 Questions
What are the two sets of teeth that humans, like most mammals, have?
Deciduous teeth and permanent teeth
Which of the following is NOT a cause of permanent teeth eruption mentioned in the text?
Gingival epithelium growth
What is the duration of Phase 1 in the process of root resorption?
4 years
What happens at the end of Phase 1 in the process of root resorption?
Primary teeth show signs of mobility
What is the role of sulcular epithelium in the process of root resorption?
It grows apically between the crown and junctional epithelium
What is the term for the process that leads to replacement of deciduous teeth by their permanent successors?
Deciduous shedding process
What is the reason why another generation of teeth is needed as mentioned in the text?
To fulfill the requisity of the growing jaw
In the shedding of deciduous anterior teeth, where do the permanent incisors and canines tooth germs initially develop in relation to their deciduous predecessors?
Apical position
What initiates the resorptive process in the shedding of deciduous anterior teeth?
Apico-lingual root surface resorption
What leads to the replacement of the primary teeth by their permanent successors in the exact position as mentioned in the text?
Apico-lingual root surface resorption
Why is another generation of teeth needed to replace the deciduous teeth?
The deciduous teeth cannot grow in size to accommodate the growing jaw
What is the pattern of shedding for deciduous anterior teeth?
Apico-lingual resorption followed by transverse plane resorption
What initiates the resorptive process in the shedding of deciduous anterior teeth?
Apico-lingual root surface
What leads to the replacement of the primary teeth by their permanent successors in the exact position?
The movement of permanent anterior tooth germs into an incisolabial direction
What is the significance of the physiologic process that leads to replacement of deciduous teeth by their corresponding permanent successors?
To fulfill the need for a new generation of teeth as the jaw grows
Study Notes
Human Dentition
- Humans, like most mammals, have two sets of teeth: deciduous (primary) teeth and permanent teeth.
Tooth Eruption
- Not a cause of permanent teeth eruption: none of the above (implying the text does not mention a specific cause)
Root Resorption
- Duration of Phase 1: not specified
- At the end of Phase 1: the roots of deciduous teeth are partially resorbed
- Role of sulcular epithelium: helps in the process of root resorption
Tooth Replacement
- Term for the process of replacing deciduous teeth with permanent successors: not specified
- Reason for another generation of teeth: deciduous teeth are small and not strong enough to last a lifetime
Deciduous Anterior Teeth
- Initial development of permanent incisors and canines tooth germs: lingual to their deciduous predecessors
- Initiation of the resorptive process: growth of the permanent tooth germs
- Pattern of shedding: deciduous anterior teeth are shed in a specific order
- Replacement of primary teeth by permanent successors: in the exact position, guided by the root of the deciduous tooth
Physiologic Process
- Significance of replacing deciduous teeth with permanent successors: allows for a more functional and efficient dental system
Explore the process of dental development and the eruption of permanent teeth. Learn about the causes of permanent teeth eruption and the phases of root resorption in the transition from primary teeth to permanent teeth.
