A kidney shaped alveolus that is wider faciolingually than
mesiodistally is in |
Permanent mandibular first premolar
|
Maximum rotation and translation of both condyles takes place during
|
Hinge movement
|
The movement that cannot be seen in horizontal plane diagram of jaw
movements is the |
Vertical movement
|
The presence of horizontal overlap in molars prevents the
|
Cheek biting
|
The major supporting cusp in the permanent maxillary first molar is
the |
Mesiopalatal. The other supporting cusps of dentition are the lingual
cusps of maxillary posterior teeth and buccal cusps of mandibular posterior teeth. |
In the permanent mandibular first molar, the central stop is provided
by the |
Central fossa
|
The oblique ridge in the occlusal surface of the permanent mandibular
first molar fits in to the concave sulcus formed by the junction of the |
Distobuccal groove; Central groove; Lingual groove
|
The outline form of pulp chamber corresponds to the
|
Shape of crown. The pulp canal corresponds to the root shape
|
Radiograph of the teeth does not reveal features of the
|
Mesial & distal aspect
|
The root canal of the posterior teeth near the apex breaks in to
multiple tiny canals system called as |
The delta system. Each of such extra canals is called as an accessory
canal and when in middle third it is called as lateral canals. |
