Anteriors Flashcards
First, second, and third tallest crowns in mouth
- Mand canine
- Max central
- Max canine
Which tooth has an incisal view that is triangle shaped
Max central
Which teeth have a trapezoid shape from the facial view
Max centrals
Which teeth have their proximal contacts at the same height
Mand centrals bc they are most symmetrical
Mand centrals appear to tilt ______
Lingually, insical edge is lingual to root axis line
Which tooth has the widest crown of all incisors
Max centrals
Mand laterals are
Larger and more rounded than centrals
Cingulum is offset to distal
Which tooth is most likely to have dens in dente
Max lateral
Lingual embrasure are larger on all teeth except which ones
Mand centrals are equal
And max first molars
Max central crown width
Longer than they are wider from facial view
What shape are incisors from proximal view
Triangles
Which teeth display the greatest variation besides the third molars
Max laterals
Which tooth has the most developed lingual anatomy
Max laterals
Which incisors have cingulum offset to the distal
Max centrals and mand laterals
When do anteriors show the first sign of calcification and what does this mean
Before the age of one
Calcification means when the teeth start forming under the gums and make a bud, not eruption
Eruption sequence of teeth
Mand centrals- 6 Mand laterals- 7 Max centrals- 7 Max laterals- 8 Mand canines- 9 Max canines- 11
All roots of incisors bend at the apex towards the distal, except which tooth
Max centrals, they are not likely to bend
Mand incisor contacts are located more ______ than max incisors
More incisal
Pulp on which tooth is wider MD than FL
Max centrals, oval shaped FLAT
Functions of incisors
Cut food
Speech: v and f sounds
Esthetics and lip support
Which tooth has an incisal view that is oval shaped
Max lateral
Where are incisors more narrow and more broad from the facial view
Narrow towards the cervical and broad towards the incisal
Most likely to be missing
- Third molars
- Max laterals
- Mand second premolars
Linguocervical groove present on which tooth
Max laterals
May cross into cementum
Overjet vs overbite
Overjet - horizontal dimension
Overbite- vertical dimension
Max incisors from incisal view
More curved
All incisors are made from how many developmental lobes
4 lobes
Lingual is called the cingulum
Mand incisors have a _____ favorable root to crown ratio
More favorable bc they have longer roots in comparison to their crown, more anchor
Mesial/distal marginal ridges and fissures/grooves are more prominent than centrals on which arch
Max laterals
Deeper lingual fossa , more caries prone
Function of incisors
Cut food like a butcher knife
Most symmetrical teeth
Mand central incisors
They do not have a sharper mesial incisal corner
Do max or mand incisors have more anatomy
Max incisors
Which tooth has poorly defined lingual anatomy
Mand laterals
CEJ on which tooth exhibits greatest depth of curvature
Max central incisor mesial view
Which incisor roots are more rounded
Max centrals, the other roots are wider FL than MD
Which tooth curves to follow the curvature of the jawline and twist. Why?
Mand laterals appear to be TWISTED
Can see the distal from the mesial view
Bc as you move distally, the incisal edge curves more lingual and the cingulum is offset
What is the first succedaneous tooth
Mand centrals
