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
