Mandibular Lateral Incisors Flashcards
Are mandibular lateral incisors symmetrical (facial view)?
No
How would you describe the incisal edge (facial view)?
Slopes distally and pulls lingually.
How would you describe the realtionship between the mesial and distal outlines (facial view)?
The mesial outline is greater than the distal outline.
How would you describe the relationship between the mesial and distal edges (facial view)?
The distal edge is more rounded.
Where is the contact for the mandibular lateral incisors? (facial view)
Both are at the incisal 1/3.
Which contact is placed a little more cervically (facial view)?
Distal contact
Which contact is placed a little more incisally (facial view)?
Mesial contact.
In comparison to mandibular central incisors how would you describe the width of the mesial-distal edge of the mandibular lateral incisor (facial view)?
Wider than the central.
How would you describe the difference between the cingulum on the central and lateral incisors of the mandible? (lingual view)
The mandibular lateral incisal cingulum is more offset to the distal than the centrals.
How would you describe the CEJ of the mandibular lateral incisor? (lingual view)
Curvature is slightly offset.
What is the relationship of the mesial marginal ridge and distal marginal ridge from the lingual view?
MMR is longer than the DMR.
How would you describe the CEJ from the mesial and distal views?
Mesial CEJ has more curvature than the Distal CEJ.
What are three important characteristics of the mandibular lateral incisors that can be seen from the incisal view?
- Not at 90 degrees
- Pull Lingually
- Follows the curvature of the arch.
When do the mandibular lateral incisors erupt?
7-8yrs
When is the root completed in the mandibular lateral incisors?
10yrs
