Incisors Flashcards
Which teeth have the function to primarily bite?
Incisors
Which teeth have the most facio-lingual axial inclination? (tilts towards the facial a lot)
Maxillary central
Which teeth have the greatest cervical curvature (on mesial end the cej curves a lot) than any other tooth?
Max. Central
Which CEJ dips deeper? anterior or posterior teeth?
Anterior
Which CEJ dips deeper? Maxillary or Mandibular
Maxillary
Which CEJ dips deeper? Mesial or distal?
Mesial
Which teeth are the only anteriors to be wider mesio-distally than facio-lingually?
Maxillary incisors
Which anterior teeth has the greatest MD crown dimension ?
Maxillary central incisor
Which anterior tooth has Inciso-cervical and Mesio-distal measurements that are almost identical?
Maxillary Central
Which contact embrasure is bigger between max central and lateral… lingual or facial?
Lingual

Where is the contact for the distal of maxillary lateral?
about the middle (furthest cervical of any tooth)
Which tooth has a longer root length (unless it’s equal) max lateral or central?
Max lateral
Which side does the mandibular central (mesial or distal) have a greater cervical curve?
Mesial (it dips more)

Yes both
Which tooth is most symmetrical?
Mand centrals
Which tooth is the smallest crown dimension?
Mand centrals

mand lateral
