Answer
|
When 2 adjacent teeth in
same arch are in contact, their curvatures adjacent to the contact area form spill way spaces called |
Embrasures. Col is the
gingiva occupying the space below the contact area in a healthy intact tooth. |
The average number of
embrasures in a contact area of healthy intact well-lined teeth are |
Four
|
The normal curvature from
cementoenamel junction to crest of cervical contour is approximately |
0.5 millimeters
|
The cervical curvature
extends about a millimeter beyond cervical line in lingual surface of |
Mandibular posterior teeth
|
The crest of cervical
curvature in permanent mandibular posterior teeth is at |
Middle third of crown
|
The curvature of cervical
line in proximal aspect will be approximately differ by |
One millimeter less
distally |
The predominant function of
incisors in humans is to |
Shear the food. Grasping is
by means of canine and grinding by means of posterior teeth |
Among all the maxillary
permanent anterior teeth the labial surface of central incisor is |
Less convex
|
The smallest mamelon in the
maxillary permanent central incisors is the |
Central
|
In the maxillary permanent
central incisors, palatally the middle and incisal third is |
Concave
