. Primary molars differ from permanent molars in that primary molars
a. have flatter facial and lingual surfaces extending from the occlusal to the cervical ridge.
b. have thicker enamel compared to the total bulk of crowns.
c. have heavier root trunks.
d. tend to have less pronounced cervical ridges.

. Embrasures are the triangular spaces or areas between adjacent teeth where the approximating surfaces diverge from the contact area. Which of the following is NOT the location of an embrasure?
a. occlusal or incisal from the contact area
b. facial (buccal or lingual) from the contact area
c. lingual from the contact area
d. cervical from the contact area

Viewed from the occlusal, the greatest faciolingual diameter of a permanent mandibular second molar is located in which third of the crown?
a. distal
b. apical
c. middle
d. mesial
e. none of these

1)have flatter facial and lingual surfaces extending from the occlusal to the cervical ridge

2)here the location of the embrasure is asked and cervically the gingival embrasure is present so i think there is no appropriate choice for this question.

3)middle .
