Answer
|
|
The deciduous maxillary second molar resembles
|
Permanent maxillary first molar. Similarly the deciduous mandibular
second molar resemble the permanent mandibular first molar |
|
In mesial aspect the bifurcation of buccal roots deciduous maxillary
second molar lies below the |
Mesiopalatal cusp
|
|
The occlusal table of the deciduous maxillary second molar is best
described as |
Rhomboid. So is the occlusal table of deciduous mandibular first
molar. |
|
Most often the deciduous maxillary second molar has ______cusp, _____
developmental groove. |
4, 4
|
|
Both the marginal ridges are well developed in
|
Deciduous maxillary second molar
|
|
The characteristic developmental depression of deciduous mandibular
first molar is found on the |
Mesial aspect
|
|
The largest cusp in the deciduous mandibular first molar is
|
Mesiolingual
|
|
The occlusal table of the deciduous mandibular second molar is best
described as |
Rectangular
|
|
The deciduous mandibular second molar has
|
3 buccal and 2 lingual cusp
|
|
The outline following the labial and buccal surfaces of maxillary
deciduous teeth is a segment of |
Eclipse
|
|
The upward and downward movement of tempromandibular joint in lower
animals is due to |
Interlocking conical form of teeth; Tempromandibular joint
morphology; Lack of muscle attachment. Because of all this factors only, the lower animals are able to move their joint in only one plane. |
|
The anatomic alignment of the teeth and their relationship to the
rest of masticatory system is the |
Occlusion
|
|
Tangential loading of masticatory stress results in
|
Reduced chewing force
|
|
The receptors in periodontium mediate tangential chewing force via
|
Negative feedback mechanism
|
|
The receptor threshold for axially directed masticatory forces
appears to be_________ as compared to the tangentially directed forces. |
Higher. It is because the axially directed force has a positive
feedback while tangential forces causes reduced chewing forces. |
|
The general age of child when the teeth of primary dentition emerge
through the alveolar gingiva is |
6 – 30 months post natal
|
|
A partial absence of bone in the form of a cleft over the root of a
tooth is |
Dehiscence
|
|
A partial absence of bone in the form of a window over the root of a
tooth is |
Fenestration
|
|
Generally the root form of any tooth is associated with
|
Over all form of the tooth; Work it carries on; Position of tooth in
the arch |
|
The measurement from cusp tip to cusp tip in posterior teeth
buccolingually is much less than the |
Buccolingual diameter of root base
