Cervical line-curves incisally-less than on mesial
Cervical line-marked, curved incisally
4. Mesial surface of the crown is convex and smooth at incisal one-third and then
flattens
Mandibular Incisors- Distal - answerCervical line-curves incisally-less than on mesial
Distal surface is similar to the mesial surfaces
Mandibular Incisors- Incisal - answerIncisal edge-almost at right angle to line bisecting
crown labio-lingually
2. Labial surface-see more than lingual surface
Mand lateral incisors- labial - answerTooth is asymmetrical-right side (M) does not
match the left (D) side of lateral
, Lateral incisor is somewhat larger than the mandibular central (exact opposite of
maxillary incisors)
Mesial side is somewhat longer than the distal side-slopes downwards somewhat
Incisal ridge-slopes downward in a distal direction
Crown is somewhat longer than mandibular central incisor
Mesial Surface and Distal Surface
Mand Lateral incisors- lingual - answerLingual form-poorly formed
Cingulum-off centered toward distal
Mand Lateral incisors- incisal - answer1. Incisal edge-is not at approximate right angle
to a line bisecting the crown labiolingually.
Max canine- labial - answerCrown is narrower mesiodistally than maxillary central
incisor (the mandibular
canine more so than the maxillary canine)
Cusp tip is in a line with the center of the root
Mesial and distal cusp ridge-mesial cusp is shorter
Shallow depressions-mesially and distally (dives labial lobes)
Of the labial lobes, the middle labial lobe is more developed
Developed Ridge runs from tip of cusp to cervical line
7. Mesial half of the crown resembles a portion of an incisor whereas the distal half
resembles a portion of a premolar
Max canine- lingual - answer1. Cingulum is better developed than maxillary central
2. Marginal ridges are strongly developed
3. Lingual ridge extends to point near the Cingulum
Mesial and Distal lingual fossae located between marginal ridges and lingual ridge
Max canine- mesial - answerGreater labiolingual measurement than any other anterior
teeth
