Most scalloped tooth?
mesial of max central incisor
If you looked at the midline of the incisal edge of the central incisors, where would it be in relation to the root of the tooth?
Centered
Maxillary incisal edges difference between mandibular incisal edges
Maxillary incisal edges are centered
are lingual to root axis except maxillary canine, which is facial to root
Maxillary central is least likely to have a?
divided canal
When extracting a tooth, due to its root shape, what is the easiest tooth to rotate?
Maxillary central
Maxillary central incisor is cut @ the CEJ. What shape is the tooth outline?
Triangular
How do permanent max centrals difference from primary centrals?
a. Longer Root
b. No Mamelons
c. No Cingulum
d. No Marginal Ridge
b. No Mamelons
Teeth with Mamelons on incisal edge intact on a adult over 30 year old indicates what?

Dens in dente has highest frequency in which tooth?
Tooth #7 & 10 (max lateral incisors)
Which tooth is most likely to have a peg lateral?
Maxillary Lateral Incisor
Girl has no caries except on max lateral. This is due to _______________ that goes into the gingiva
lingual groove
Maxillary lateral has a lingual groove that extends from enamel to cementum?
palato-radicular groove
Problem with root planning a maxillary lateral?
Inciso-apical fissure
Most likely to be congenitally missing:

Which tooth is most likely to be trifurcated?
Maxillary 1st PM
Maxillary 1st PM is the only permanent tooth with a longer mesial slope than _________________ on the facial
distal slope
Describe Primary maxillary canine
only primary tooth with mesial slope than distal slope
Lingual cusp of the max 1st PM compared to the facial cusp?
Shorter
Max 1st PM is most simiar to what man 2nd PM?
H type, Y type, U type
In which tooth is the lingual dimension greater than buccal dimension?
Maxillary 1st Molar
- because of the Cusp of Carabelli
