Quiz 3
1.)On incisors, the number of lobes on the facial surface, which is the name number of
mamelons on the lingual surface is:
One
Two
Three
I’m confused about this question.
I know that an incisor has 4 total lobes.
Are you asking for the total number or just
the number on the facial surface?
Four
2.) Which of the following is NOT a possible line angle of an incisor crown?
Mesiolabial line angle
Distolingual line angle
Mesiolingual line angle
Mesiodistal line angle
3.) Which tooth has the shortest root relative to its crown?
Mandibular lateral incisor
Maxillary lateral incisor
Mandibular central incisor
Maxillary central incisor
4.) When holding both any maxillary & mandibular incisor, which characteristic is most likely
to apply to the mandibular incisor but NOT the maxillary incisors
The cingulum is off center toward the distal
on mandibular incisors
From the incisal view, the labiolingual
dimension is greater than the mesiodistal
dimension on mandibular incisors
The root is more likely to be straight than
bent to the distal on mandibular incisors
The crown has lingual ridges & fossae that
are most prominent on the mandibular
incisors
5.) Which teeth are considered the "Cornerstones of the Mouth"
Lateral incisors
Canines
Central incisors
None of the above
6.) Compared to premanent maxillary lateral incisors, maxillary central incisors are more
likely to exhibit:
Smaller crowns
The cingulum is positioned distally
Lingual pits
Deeper & smaller lingual fossae
7.) Which statement is true regarding the wear patterns of the incisal edges of anterior teeth
in ideal occlusion?
Maxillary central incisors are likely to exhibit
wear on the labial/facial part of the incisal
edge
Maxillary canines are likely to exhibit ear on
the labial/facial part of the incisal edge
Mandibular incisors are likely to exhibit wear
on facial part of the incisal edge
Mandibular canines are likely to exhibit wear
on the lingual part of the incisal edge
8.) All but one type of incisor have a mesioincisal angle more square (more acute) than the
distal angle. Which incisor is the exception?
Maxillary cental incisor
Maxillary lateral incisor
Mandibular central incisor
Mandibular lateral incisor
9.) Which of the following characteristics is seen
most of the time
on ALL permanent
incisors?
The proximal view is pentagon shaped
The root is longer than the crown
The distoincisal angle is more acute/sharper
than the mesioincisal angle
Facial & lingual crests of curvature are
located in the middle third
10.) When holding both a maxillary & mandibular incisor, which characteristic can be used to
determine which tooth is the maxillary incisor?
The maxillary incisal edge is rotated or
twisted when viewed from the incisal
The maxillary cingulum is centered when
viewed from the incisal
The maxillary root has prominent longitudinal
grooves in both surfaces
The maxillary crown has lingual ridges &
fossa that are more prominent
11.) When holding both an extracted maxillary & mandibular incisor from the same mouth,
which characteristic will apply to ONLY the maxillary incisor?
The mesiodistal dimension is narrower
compared to the incisocervical length
The lingual anatomy is more prominent with
marginal ridges & deeper fossa
The incisal edge is lingual to or centered on
the midroot axis
Proximal contact areas are closer to the
incisal edge
12.) The distal contact area of the permanent maxillary central incisor is located in the:
Incisal third
Junction of the incisal & middle third
Junction of the middle & cervical third
Cervical third
