Mandibular Incisors Flashcards
Which tooth has the smaller dimension? Mandibular central/lateral incisor
Mandibular central incisor.
Mandibular central incisor has a small mesial distal dimension and a smaller inciso cervical dimension.
Which incisor has the straightest, flattest incisal edge?
Mandibular central incisor.
Very straight and flat. The lateral incisor has more curvature, especially towards the distal surface.
Which tooth has a more square distal incisal angle?
Mandibular central incisor.
The rounding in the distal incisal corner for the lateral is more rounded than the central.
Which one of these teeth has a proximal contact that is located further cervically than the other?
Mandibular lateral incisor.
Which one of these teeth has the least amount of convexity to its distal surface?
Mandibular lateral incisor.
Which tooth has a longer / wider root?
Mandibular lateral incisor.
Which tooth has a larger faciolingual crown dimension?
Mandibular lateral incisor.
Note* this is the opposite of the maxillary incisors.
What is unique about the distal view of the mandibular lateral incisor?
When viewed distally, more of incisal edge is visible on lateral incisors.
The distal proximal contact is located farther cervically on the mandibular lateral incisor.
Which one of these would have an incisal edge that is perpendicular to the facial lingual bisector?
Mandibular Central incisor
Which tooth has a crown that appears to be twisted on its root?
Mandibular Lateral incisor
Which tooth appears to be bilaterally symmetrical?
Mandibular Central incisor.
Only tooth of the mouth where the crown of the tooth is bilaterally symmetrical. The mesial half is equal to the distal half of the tooth.
Which tooth has both proximal contacts located at the same incisocervical location?
