1. How are mandibular central incisors different from lateral incisors from the labial view?
Four ways... |
1. More symmetrical crown
2. No distal bulge on crown 3. Proximal contacts at same level mesial and distal 4. Smaller than lateral incisors in same mouth |
|
2. How are mandibular lateral incisors different from centrals from the labial view?
Five ways... |
1. Less symmetrical crown
2. Tips to distal 3. Distal bulge on side of crown 4. Mesial contact is more incisal 5. Larger than centrals |
|
3. What traits differentiate the right central incisor from the left from the labial view?
|
Nothing
Very symmetrical crown so cannot tell left from right |
|
4. What traits differentiate the right lateral incisor from the left from the labial view?
Three things.. |
1. Crown tips to distal
2. Distal crown outline bulges more than mesial 3. Distal contact is more cervical |
|
5. How are mandibular central incisors different from lateral incisors from the lingual view?
Two things.. |
1. Cingulum is centered
2. Same length mesial and distal marginal ridge |
|
6. How are mandibular lateral incisors different from central incisors from the lingual view?
Two things.. |
1. Cingulum is distal
2. Longer mesial marginal ridge |
|
7. What traits differentiate the right centrall incisor from the left from the lingual view?
|
Nothing
Very symmetrical and cannot tell |
|
8. What traits differentiate the right lateral incisor from the left from the lingual view?
Three things.. |
1. Same traits as from labial
2. Cingulum is distal 3. Shorter distal marginal ridge |
|
9. How are mandibular central incisors different from lateral incisors from the proximal view?
|
View is not good to differentiate central from later
|
|
10. What traits differentiate the right central incisor from the left from the proximal view?
Two things... |
1. Distal incisal ridge even with mesial incisal ridge
2. Mesial cervical line curves greater that distal |
|
11. What traits differentiate the right lateral incisor from the left from the proximal view?
Two things... |
1. Distal incisal ridge may be more lingual
2. Mesial cervical line curves greater than distal |
|
12. Do maxillary central and lateral incisors have root depressions?
|
Central
-no mesial root depression (or slight or flat) -No distal root depression Lateral -Yes mesial root depression -No distal root depression |
|
13. Do mandibular central and lateral incisors have root depressions?
|
Central
-Yes mesial root depression -Yes (deeper) distal root depression Lateral -Yes mesial root depression -Yes (deeper) distal root depression |
|
14. What traits differentiate the mandibular central incisor from the later incisor from the incisal view?
Two things... |
1. No distolingual twist of incisal edge
2. Cingulum is centered |
|
15. What traits differentiate the mandibular laterl incisor from the later central from the incisal view?
Two things... |
1. Distolingual twist of incisal edge
2. Cingulum is offset to distal |
|
16. What traits differentiate the right from left mandibular central incisor from the incisal view?
|
Nothing - very symmetrical
|
|
17. What traits differentiate the right from left mandibular later incisors from the incisal view?
Two things... |
1. Distolingual twist of incisal edge
2. Cingulum is offset to distal |
|
18. Describe the cingulum position on maxillary anterior teeth.
|
Centrals - distal
Lateral - center Canines - center |
|
19. Describe the cingulum position on mandibular anterior teeth.
|
Centrals - center
Lateral - distal Canines - distal |
