Answer 3

Mesial root

Question 4

The type of cement that is not indicated for permanent cementation for indirect restorations.

Answer 4

Zinc oxide eugenol

Question 5

Teeth with this characteristic are poor candidates for an all-ceramic crowns because they do not have enough preparation length to support the lingual and incisal surfaces of the restoration.

Question 8

Cement that adheres to enamel and dentin with good biocompatibility. It is more translucent than zinc phosphate cement.

Answer 8
