The most primitive cusp of
the permanent maxillary first molar is the |
Mesiopalatal cusp
|
|
The outline of the root
trunk of permanent maxillary first molar reminds of the _________________ stage of human tooth evolution. |
Tritubercular. Both the
root trunk and the stage are triangular. |
|
The occlusal table of
permanent maxillary first molar is made up of |
2 major and 2 minor fossa.
The major fossa (central, distal) and minor (mesial triangular and distal triangular)fossa. In a permanent mandibular first molar it is 1 major fossa (central fossa) and 2 minor fossa (distal and mesial fossa) |
|
In the permanent mandibular
first molar, the mesiobuccal developmental groove separates the |
Mesiobuccal lobe and
distobuccal lobe. The distobuccal developmental groove separates distobuccal lobe from distal lobe. |
|
Tubercle of Zuckerland is
associated with |
Deciduous maxillary first
molar. It is a tubercle found in the deciduous maxillary first molar on the facial or the buccal aspect near the cervical ridge. |

maxillary central incisor, incisal surface inclines cervically from the labioincisal edge to the palatoincisal edge by an angle of |
45 degrees
|
|
A typical human permanent
maxillary lateral incisor is positioned by an angle of ______ degrees to the occlusal plane. |
65

|
A typical human permanent
maxillary lateral incisor is positioned by an angle of ______ degrees to the mid saggital plane. |
10

|
In human permanent
dentition, the teeth that exhibit a bilateral symmetrical form from facial aspect is |
Mandibular central incisor.
Maxillary central incisors have a rounded distoincisal angle and sharp mesioincisal angle. Maxillary canine have unequal slopes. Mandibular lateral incisor towards the distal side has a slope. |

centric stops for opposing cusps is the |
Marginal ridge
