Question	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
