Tooth Morphology

Question
Answer
The palatal topography of in the entire maxillary permanent central incisors from proximal aspect resembles a
Scoop
The most prominent teeth in the mouth are the
Permanent maxillary first molar
Most often the maxillary permanent central incisors has
Sharp mesioincisal angle; round distoincisal angle
A line drawn through the center of root and crown of permanent maxillary central incisor tends to be parallel to the
Mesial outline of crown and root
The cross section of root at cervix of permanent maxillary central incisor is
Triangular with rounded edges and apex palatally
The relationship of the line drawn through the mesial aspect of permanent maxillary central incisor through the center of tooth with the line joining the apex of root with incisal ridge is such that they
Bisect the latter
The permanent maxillary central incisor incisal surface has
Palatal inclination. The mandibular incisors has a labial inclination
The relationship of mesiodistal and buccopalatal diameter of permanent maxillary central incisor is that
Greater mesiodistal and lesser buccopalatal width
The teeth that is highly variable in form and shape next to third molars is the
Permanent maxillary lateral incisor
A rounded mesioincisal angle is characteristic of
Permanent maxillary lateral incisor
