Principles of Adhesion

Question 1

cohesive forces like ionic, covalent, and metallic are blank bonds

Answer 1

primary

Question 2

twot types of secondary bonds

Answer 2

hydrogen bonds, van der waals forces

Question 3

bond between positive and negative that has electron trransfer

Answer 3

ionic

Question 4

bonds characterized by sharing electrons with very precise bond orientations

Answer 4

covalent bonds

Question 5

electron sharing among metals type of bond

Answer 5

metallic bond

Question 6

secondary bonds do not involve blank

Answer 6

electron sharing

Question 7

secondary bonds depend on blank forces

Answer 7

polar

Question 8

leakage adjacent to dental restorative materials results from an insufficient or incomplete blank

Answer 8

adhesion

Question 9

adhesion is when blank molecules are attracted to each other

Answer 9

unlike

Question 10

when molecules of the same kind are attracted

Answer 10

cohesion

Question 11

when molecules of the same kind are attracted

Answer 11

cohesion

Question 12

material or film used to cause adhesion is known as a blank

Answer 12

adhesive

Question 13

material to which adhesive is applied is called the blank

Answer 13

adherend

Question 14

bonding or retention that does not include molecular attraction

Answer 14

mechanical bonding

Question 15

bonding mechanism commonly used in dentistry because of the absence of truly adhesive cements or restorative materials

Answer 15

micromechanical bonding

Question 16

wetting does not require a blank

Answer 16

liquid

Question 17

wetting involves creating a blank by minimizing space between objects

Answer 17

adhesion

Question 18

extent to which an adhesive wets the surface of an adherent may be determined by measuring the blank between the adhesive and adherend

Answer 18

contact angle

Question 19

contact angle of wetting agent should be very very blank

Answer 19

tiny

Question 20

three common dental biomaterials

Answer 20

ceramic, metallic, plastic
